blankets will greatly increase starting capability at low temperatures. Suitable battery blankets are available from your authorized MOPAR威 dealer. Engine Starting Procedure

WARNING!

NEVER pour fuel or other flammable liquid into the air inlet opening in an attempt to start the vehicle. This could result in a flash fire causing serious personal injury.

1. The shift lever must be in the NEUTRAL or PARK position before you can start the engine. 2. Turn the ignition key to the ON position. 3. Watch for the “Wait To Start Light” in the instrument cluster. Refer to “Instrument Cluster” in Section 4 of this manual. It will glow for two to ten seconds or more,

284 STARTING AND OPERATING

depending on engine temperature. When the “Wait To Start” goes out, the engine is ready to start. 4. Tip Start Feature Do not press the accelerator. Use the Fob with Integrated Key (FOBIK) to briefly turn the ignition switch to the START position and then release it. The starter motor will continue to run, and it will automatically disengage when the engine is running. If the engine fails to start, the starter will disengage automatically in 20 seconds. The starter can be disengaged by turning the ignition key to the OFF position, if required. 5. After the engine starts, allow it to idle for approxi- mately 30 seconds before driving. This allows oil to circulate and lubricate the turbocharger. Avoid prolonged idling in ambient temperatures below 0°F (-18°C). Long periods of idling may be harmful to your engine because combustion chamber temperatures can drop so low that the fuel may not burn completely.

Incomplete combustion allows carbon and varnish to form on piston rings and injector nozzles. Also, the unburned fuel can enter the crankcase, diluting the oil and causing rapid wear to the engine. Engine Warm-Up Avoid full throttle operation when the engine is cold. When starting a cold engine, bring the engine up to operating speed slowly to allow the oil pressure to stabilize as the engine warms up. NOTE: High-speed, no-load running of a cold engine can result in excessive white smoke and poor engine performance. No-load engine speeds should be kept under 1,200 RPM during the warm-up period, especially in cold ambient temperature conditions. If temperatures are below 32°F (0°C), operate the engine at moderate speeds for five minutes before full loads are applied.

Engine Idling - In Cold Weather Avoid prolonged idling in ambient temperatures below 0°F (-18°C). Long periods of idling may be harmful to your engine because combustion chamber temperatures can drop so low that the fuel may not burn completely. Incomplete combustion allows carbon and varnish to form on piston rings and injector nozzles. Also, the unburned fuel can enter the crankcase, diluting the oil and causing rapid wear to the engine. Stopping The Engine Before turning off your turbo diesel engine, always allow the engine to return to normal idle speed and run for several seconds. This assures proper lubrication of the turbocharger. This is particularly necessary after any period of hard driving. Idle the engine a few minutes before routine shutdown. After full load operation, idle the engine three to five minutes before shutting it down. This idle period will

STARTING AND OPERATING 285

allow the lubricating oil and coolant to carry excess heat away from the combustion chamber, bearings, internal components, and turbocharger. This is especially impor- tant for turbocharged, charge air cooled engines.

ENGINE BLOCK HEATER — IF EQUIPPED The engine block heater warms the engine, and permits quicker starts in cold weather. Connect the heater cord to a ground-fault interrupter protected 110-115 Volt AC electrical outlet with a grounded, three-wire extension cord. Use the heater when temperatures below 0°F (-18°C) are expected to last for several days. The block heater must be plugged in at least one hour to have an adequate warming effect on the coolant. The engine block heater cord is located: • 3.7L/4.7L Engine — coiled and strapped to the engine

oil dipstick tube.

286 STARTING AND OPERATING

harness.

• 5.7L Engine — bundled and fastened to the injector • 3.0L Diesel Engine — on the passenger side of the vehicle, mounted on a stud between the fresh airbox and coolant reservoir.

WARNING!

Remember to disconnect the cord before driving. Damage to the 110-115 Volt AC electrical cord could cause electrocution.

AUTOMATIC TRANSMISSION

CAUTION!

a complete stop.

Damage to the transmission may occur if the follow- ing precautions are not observed: • Shift into PARK only after the vehicle has come to • Shift into or out of REVERSE only after the vehicle has come to a complete stop and the engine is at idle speed. • Do not shift from REVERSE, PARK, or NEUTRAL into any forward gear when the engine is above idle speed. • Before shifting into any gear, make sure your foot

is firmly on the brake pedal.

WARNING!

It is dangerous to move the shift lever out of PARK or NEUTRAL if the engine speed is higher than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accelerate quickly forward or in reverse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your foot is firmly on the brake pedal.

Brake/Transmission Shift Interlock System This system prevents you from moving the shift lever out of PARK and into any gear unless the brake pedal is pressed. This system is active only while the ignition switch is in the ON position. Always depress the brake pedal first, before moving the shift lever out of PARK.

STARTING AND OPERATING 287

Brake/Transmission Interlock Manual Override Your vehicle may be equipped with a shift lock manual override. The manual override may be used in the event that the shift lever should fail to move from PARK with the key in the ON position and the brake pedal de- pressed. To operate the shift lock manual override, per- form the following steps: 1. Turn the key to the ON position without starting the engine. 2. Firmly set the parking brake. 3. Using a flat blade screwdriver, carefully remove the shift lock manual override cover, which is located on the PRNDL bezel. 4. Depress and maintain firm pressure on the brake pedal.

288 STARTING AND OPERATING

5. Using the screwdriver, reach into the manual override opening. Press and hold the shift lock lever down.

Interlock Manual Override

6. Move the shift lever into the NEUTRAL position. 7. The vehicle may then be started in NEUTRAL.

Have your vehicle inspected by your local authorized dealer, if the shift lock manual override has been used. Five–Speed Automatic Transmission The electronically controlled transmission provides a precise shift schedule. The transmission electronics are self-calibrating; therefore, the first few shifts on a new vehicle, may be somewhat abrupt. This is a normal condition, and precision shifts will develop within a few hundred miles/kilometers. Gear Ranges

NOTE: After selecting any gear range, wait a moment to allow the selected gear to engage before accelerating. This is especially important when the engine is cold. If there is a need to restart the engine, be sure to cycle the key to the LOCK position before restarting. Transmission gear engagement may be delayed after restarting the engine if the key is not cycled to the LOCK position first.

PARK This gear position supplements the parking brake by locking the transmission. The engine can be started in this range. Never use PARK while the vehicle is in motion. Apply the parking brake when leaving the vehicle in this range. Always apply the parking brake first, then place the shift lever into the PARK position.

WARNING!

• Never use the PARK position as a substitute for the parking brake. Always apply parking brake fully when parked to guard against vehicle move- ment and possible injury or damage.

(Continued)

STARTING AND OPERATING 289

WARNING! (Continued)

• It is dangerous to move the shift lever out of PARK or NEUTRAL if the engine speed is higher than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accelerate quickly forward or in reverse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your right foot is firmly on the brake pedal.

REVERSE Use this range only after the vehicle has come to a complete stop. NEUTRAL Shift into NEUTRAL when the vehicle is standing for prolonged periods with the engine running. The engine may be started in this range. Set the parking brake if you must leave the vehicle.

290 STARTING AND OPERATING

NOTE: Towing the vehicle, coasting, or driving for any other reason with the shift lever in NEUTRAL can result in severe transmission damage. Refer to “Recreational Towing” in Section 5 and “Towing a Disabled Vehicle” in Section 6 of this manual. DRIVE Shift into DRIVE only when the vehicle is at a complete stop and the brakes are firmly applied. The transmission automatically upshifts through fifth gear. The DRIVE position provides optimum driving characteristics under all normal operating conditions. Electronic Range Select (ERS)Operation The Electronic Range Select (ERS) shift control allows you to move the shift lever left (-) or right (+) when the shift lever is in the DRIVE position, allowing you to limit the highest available gear. For example, if the driver

shifts the transmission into ERS 3 (third gear), the trans- mission will never shift above third gear, but can shift down to 2 (second) or 1 (first), when needed. NOTE: • If you pull and hold (not tap) the shift lever to the left (-), the transmission will downshift to the lowest gear that can be attained without overrevving the engine. The display will show the gear the vehicle is in and will limit the top gear to the one displayed. • If you pull and hold (not tap) the shift lever to the right (+), the transmission will exit the gear limiting mode and shift to the appropriate gear. The display will read ⬙D⬙.

3.7L and 3.0L Diesel Engine When in the DRIVE position, the first tap to the left (-), will shift down one gear and will display that gear. For example, if you are in DRIVE and are in 5th gear, when you tap the shift lever one time to the left (-), the

transmission will downshift to 4th gear and the display will show 4. Another tap to the left (-) will shift the transmission into 3rd gear. 4.7L and 5.7L Engine On vehicles equipped with 4.7L or 5.7L engines, use of ERS (or TOW/HAUL mode) also enables an additional underdrive gear which is not normally used during through-gear accelerations. This additional gear im- proves vehicle performance and cooling capability when towing a trailer on certain grades. ERS 1,2, and 3 are underdrive gears; ERS 4 is direct drive. ERS 5 (Overdrive) is the same as the normal 4th gear. When in the DRIVE position in 1st through 4th gear, the first tap to the left (-), will display the ERS designation for the current gear (the transmission will not downshift). For example, if you are in DRIVE and are in 3rd (direct) gear, when you tap the shift lever one time to the left (-), the display will show 4
(ERS 4 is direct gear). Another tap to the left (-) will shift the transmission down to ERS 3 (the added underdrive

STARTING AND OPERATING 291

gear). When in the DRIVE position in 5th gear, the first tap to the left (-) will downshift the transmission and display 5 (ERS 5 is the same as normal 4th gear). Another tap to the left (-) will shift the transmission down to ERS 4 (direct gear).

WARNING!

Do not downshift for additional engine braking on a slippery surface. The drive wheels could lose their grip and the vehicle could skid.

Overdrive Operation The automatic transmission includes an electronically controlled Overdrive (5th gear for 3.7L and 3.0L diesel engine, 4th and 5th gears for 4.7L and 5.7L engines). The transmission will automatically shift to Overdrive, if the following conditions are present: • the transmission selector is in DRIVE; • the engine coolant has reached normal operating tem- • vehicle speed is above approximately 30 mph • the TOW/HAUL switch has not been activated;

operating

If the vehicle is started in extremely cold tem- NOTE: peratures, the transmission may not shift into Overdrive and will automatically select the most desirable gear for operation at this temperature. Normal operation will resume when the transmission fluid temperature has risen to a suitable level. Refer also to the Note under torque converter clutch, later in this section. During cold temperature operation you may notice de- layed upshifts, depending on engine and transmission temperature. This feature improves the warmup time of the engine and transmission. If the transmission temperature gets extremely hot, the transmission will automatically select the most desirable gear for operation at this temperature. If the transmission temperature becomes hot enough, the “TRANSMISSION

OVER TEMP” message may display, and the transmis- sion may downshift out of Overdrive until the transmis- sion cools down. After cool down, the transmission will resume normal operation. In high ambient temperatures with sustained high engine speed and load, an upshift, followed shortly thereafter by a downshift, may occur. The TOW/HAUL light will turn off. This is a normal part of the overheat protection strategy when operating in the TOW/HAUL mode. The transmission will downshift from Overdrive, to the most desirable gear, is fully depressed at vehicle speeds above approximately 35 mph (56 km/h). When To Use TOW/HAUL Mode — If Equipped When driving in hilly areas, towing a trailer, carrying a heavy load, etc., and frequent transmission shifting oc- curs, press the TOW/HAUL switch. This will improve performance and reduce the potential for transmission

overheating or failure due to excessive shifting. When operating in TOW/HAUL mode, the transmission will shift into direct gear and Overdrive will be enabled under steady cruise conditions.

TOW/HAUL Switch

The “TOW/HAUL” indicator light will illuminate in the instrument cluster to indicate when the switch has been

294 STARTING AND OPERATING

activated. Pressing the switch a second time restores normal operation. If the TOW/HAUL mode is desired, the switch must be pressed each time the engine is started. Transmission Limp Home Mode Transmission function is monitored for abnormal condi- tions. If a condition is detected that could result in transmission damage, the transmission limp home mode will be engaged. In this mode, the transmission will remain in the current gear (3.7L and 3.0L diesel engine) or in direct gear (4.7L and 5.7L engines) until the vehicle is brought to a stop. To reset the transmission, use the following procedure: 1. Stop the vehicle. 2. Move the shift lever into the PARK position. 3. Turn the engine off, and be sure to turn the key to the LOCK position.

4. Wait approximately 10 seconds, then restart the en- gine. 5. Move the shift lever to the desired gear range. If the problem is no longer detected, the transmission will return to normal operation. If the problem persists, PARK, REVERSE, and NEUTRAL will continue to oper- ate. Only 2nd gear (3.7L and 3.0L diesel engine) or 3rd gear (4.7L and 5.7L engines) will be available in the DRIVE position. Have the transmission checked at your authorized dealer as soon as possible. Torque Converter Clutch A feature, designed to improve fuel economy, has been included in the automatic transmission on your vehicle. A clutch within the torque converter engages automati- cally, at a calibrated speed, at light throttle. It engages at higher speeds under heavier acceleration. This may re- sult in a slightly different feeling or response during normal operation in high gear. When the vehicle speed

drops below a calibrated speed, or during acceleration, the clutch automatically and smoothly disengages. The feature is operational in Overdrive and in DRIVE. NOTE: • The torque converter clutch will not engage until the transmission fluid and engine coolant are warm [usu- ally after 1 to 3 miles (1.6 to 4.8 km) of driving]. Because the engine speed is higher when the torque converter clutch is not engaged, it may seem as if the transmission is not shifting into Overdrive when cold. This is normal. Manually shifting (using the ERS shift control) between 4 (direct gear) and 5/D (Overdrive gear) positions will demonstrate that the transmission is able to shift into and out of Overdrive. For vehicles with 4.7L or 5.7L engines (which have two Overdrive gears), the transmission may not shift into the top Overdrive gear (normal 5th gear) until the transmis- sion fluid and engine coolant are warm.

STARTING AND OPERATING 295

• If the vehicle has not been driven in several days, the first few seconds of operation after shifting the trans- mission into gear may seem sluggish. This is due to the fluid partially draining from the torque converter into the transmission. This condition is normal and will not cause damage to the transmission. The torque con- verter will refill within five seconds of shifting from PARK into any other gear position.

Rocking The Vehicle If the vehicle becomes stuck in snow, sand, or mud, it can often be moved by a rocking motion. Move the shift lever between DRIVE and REVERSE, while applying slight pressure to the accelerator. NOTE: The Electronic Stability Program (ESP) and Traction Control (if equipped) should be turned OFF before attempting to rock the vehicle. Refer to “Electronic Brake Control System” in Section 3 of this manual.

296 STARTING AND OPERATING

The least amount of accelerator pedal pressure to main- tain the rocking motion, without spinning the wheels or racing the engine, is most effective. Racing the engine or spinning the wheels, due to the frustration of not freeing the vehicle, may lead to transmission overheating and failure. Allow the engine to idle with the shift lever in NEUTRAL for at least one minute after every five rocking-motion cycles. This will minimize overheating and reduce the risk of transmission failure during pro- longed efforts to free a stuck vehicle.

CAUTION!

When “rocking” a stuck vehicle by moving between “First” and REVERSE, do not spin the wheels faster than 15 mph (24 km/h), or drivetrain damage may result.

FOUR-WHEEL DRIVE OPERATION

Quadra-Trac I姞 Operating Instructions/Precautions — If Equipped The Quadra-Trac I威 is a single-speed (HI range only) transfer case, which provides convenient full-time four– wheel drive. No driver interaction is required. The Brake Traction Control System (BTC), which combines standard ABS and Traction Control, provides resistance to any wheel that is slipping to allow additional torque transfer to wheels with traction. NOTE: The Quadra-Trac I威 system is not appropriate for conditions where 4WD LOW range is recommended. Refer to “Off-Road Driving Tips” in this section.

Quadra-Trac II姞 Operating Instructions/Precautions — If Equipped The Quadra-Trac II威 transfer case is fully automatic in the normal driving 4WD HI mode. The Quadra-Trac II威 transfer case provides three mode positions — 4WD HI, NEUTRAL, and 4WD LOW. This transfer case is fully automatic in the 4WD HI mode. When additional traction is required, the 4WD LOW position can be used to lock the front and rear driveshafts together and force the front and rear wheels to rotate at the same speed. The 4WD LOW position is intended for loose, slippery road surfaces only. Driving in the 4WD LOW position on dry hard surfaced roads may cause increased tire wear and damage to driveline components. When operating your vehicle in 4WD LOW, the engine speed is approximately three times that of the 4WD HI position at a given road speed. Take care not to overspeed the engine and do not exceed 25 mph (40 km/h).

STARTING AND OPERATING 297

Proper operation of four-wheel drive vehicles depends on tires of equal size, type, and circumference on each wheel. Any difference will adversely affect shifting and cause damage to the transfer case. Because four-wheel drive provides improved traction, there is a tendency to exceed safe turning and stopping speeds. Do not go faster than road conditions permit.

WARNING!

You or others could be injured if you leave the vehicle unattended with the transfer case in the N (Neutral) position without first fully engaging the parking brake. The transfer case N (Neutral) position disengages both the front and rear driveshafts from the powertrain and will allow the vehicle to move regardless of the transmission position. The parking brake should always be applied when the driver is not in the vehicle.

298 STARTING AND OPERATING

Shift Positions

For additional information on the appropriate use of each transfer case mode position, see the information below: 4WD HI All roads surfaces such as ice, snow, gravel, sand, and dry hard pavement. NEUTRAL Disengages both the front and rear driveshafts from the powertrain. To be used for flat towing behind another vehicle. Refer to “Recreational Towing” in Section 5 of this manual. 4WD LOW Low speed four-wheel drive. Locks the front and rear driveshafts together. Forces the front and rear wheels to rotate at the same speed. Additional traction and maxi- mum pulling power for loose, slippery road surfaces only. Do not exceed 25 mph (40 km/h).

Shifting Procedures

4WD HI to 4WD LOW With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), key ON or engine running, shift the transmission into NEUTRAL, and raise the transfer case T-handle. The “4WD LOW” indicator light in the instrument cluster, will begin to flash and remain on solid when the shift is complete. Release the T-handle. If shift conditions/interlocks are not met, or a NOTE: transfer case motor temperature protection condition exists, a “CHECK SHIFT PROCEDURES” message will flash from the EVIC (Electronic Vehicle Information Cen- ter). Refer to “Electronic Vehicle Information Center (EVIC)” in Section 4 of this manual.

STARTING AND OPERATING 299

“4WD LOW” indicator light in the instrument cluster, will flash and go out when the shift is complete. Release the T-handle. NOTE: • If shift conditions/interlocks are not met, or a transfer case motor temperature protection condition exists, a “CHECK SHIFT PROCEDURES” message will flash from the EVIC (Electronic Vehicle Information Center). to “Electronic Vehicle Information Center Refer (EVIC)” in Section 4 of this manual. • Shifting into or out of 4WD LOW is possible with the vehicle completely stopped, however difficulty may occur due to the mating clutch teeth not being prop- erly aligned. Several attempts may be required for clutch teeth alignment and shift completion to occur. The preferred method is with the vehicle rolling 0 to 3 mph (0 to 5 km/h). If the vehicle is moving faster than 3 mph (5 km/h), the transfer case will not allow the shift.

Shifter T-Handle

4WD LOW to 4WD HI With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), key ON or engine running, shift the transmission into NEUTRAL, and raise the transfer case T-handle. The

300 STARTING AND OPERATING

NEUTRAL Shift Procedure 1. Key ON, engine off. 2. Vehicle stopped, with foot on brake. 3. Place transmission into NEUTRAL. 4. Hold down the NEUTRAL “pin” switch (with a pen, etc.) for four seconds until the LED lamp by the switch starts to blink indicating shift in progress. The lamp will stop blinking (stay on solid) when the NEUTRAL shift is complete. A “4WD SYSTEM IN NEUTRAL” message will display on the EVIC (Electronic Vehicle Information Center). Refer to “Electronic Vehicle Information Center (EVIC)” in Section 4 of this manual.

Neutral Switch

5. Repeat Steps 1 to 4 to shift out of NEUTRAL. If shift conditions/interlocks are not met, a NOTE: “CHECK SHIFT PROCEDURES” message will flash from the EVIC (Electronic Vehicle Information Center). Refer to “Electronic Vehicle Information Center (EVIC)” in Section 4 of this manual.

Quadra-Drive II姞 System — If Equipped The optional Quadra-Drive II威 System features three torque transfer couplings. The couplings include ELSD (Electronic Limited-Slip Differential) front and rear axles and Quadra-Trac II威 transfer case. The optional ELSD axles are fully automatic and require no driver input to operate. Under normal driving conditions, the units function as standard axles, balancing torque evenly be- tween left and right wheels. With a traction difference between left and right wheels, the coupling will sense a speed difference. As one wheel begins to spin faster than the other, torque will automatically transfer from the wheel that has less traction, to the wheel that has traction. While the transfer case and axle couplings differ in design, their operation is similar. Follow the Quadra-Trac II威 transfer case shifting information, preceding this section, for shifting this system.

STARTING AND OPERATING 301

ON-ROAD DRIVING TIPS Utility vehicles have higher ground clearance and a narrower track to make them capable of performing in a wide variety of off-road applications. Specific design characteristics give them a higher center of gravity than ordinary cars. An advantage of the higher ground clearance is a better view of the road, allowing you to anticipate problems. They are not designed for cornering at the same speeds as conventional two-wheel drive vehicles any more than low-slung sports cars are designed to perform satisfacto- rily in off-road conditions. If at all possible, avoid sharp turns or abrupt maneuvers. As with other vehicles of this type, failure to operate this vehicle correctly may result in loss of control or vehicle rollover.

302 STARTING AND OPERATING

OFF-ROAD DRIVING TIPS

NOTE: Prior to off-road driving, remove the front air dam to prevent damage. The front air dam is attached to the lower front fascia with quarter turn fasteners, and can be removed by hand. When To Use 4WD LOW Range — If Equipped When off-road driving, shift to 4WD LOW for additional traction. This range should be limited to extreme situa- tions such as deep snow, mud, or sand where additional low speed pulling power is needed. Vehicle speeds in excess of 25 mph (40 km/h) should be avoided when in 4WD LOW range. Driving Through Water Although your vehicle is capable of driving through water, there are a number of precautions that must be considered before entering the water.

CAUTION!

When driving through water, do not exceed 5 mph (8 km/h). Always check water depth before entering as a precaution, and check all fluids afterward. Driv- ing through water may cause damage that may not be covered by the new vehicle limited warranty.

Driving through water more than a few inches/ centimeters deep will require extra caution to ensure safety and prevent damage to your vehicle. If you must drive through water, try to determine the depth and the bottom condition (and location of any obstacles) prior to entering. Proceed with caution and maintain a steady controlled speed less than 5 mph (8 km/h) in deep water to minimize wave effects.

Flowing Water If the water is swift flowing and rising (as in storm run-off) avoid crossing until the water level recedes and/or the flow rate is reduced. If you must cross flowing water avoid depths in excess of 9 in (23 cm). The flowing water can erode the streambed causing your vehicle to sink into deeper water. Determine exit point(s) that are downstream of your entry point to allow for drifting. Standing Water Avoid driving in standing water deeper than 20 in (51 cm), and reduce speed appropriately to minimize wave effects. Maximum speed in 20 in (51 cm) of water is less than 5 mph (8 km/h). Maintenance After driving through deep water, inspect your vehicle fluids and lubricants (engine oil, transmission oil, axle,

STARTING AND OPERATING 303

transfer case) to assure the fluids have not been contami- nated. Contaminated fluid (milky, foamy in appearance) should be flushed/changed as soon as possible to pre- vent component damage. Driving In Snow, Mud And Sand In heavy snow, when pulling a load, or for additional control at slower speeds, shift the transmission to a low gear and shift the transfer case to 4WD LOW if necessary. Refer to “Four-Wheel Drive Operation” in this section. Do not shift to a lower gear than necessary to maintain forward motion. Over-revving the engine can spin the wheels and traction will be lost. Avoid abrupt downshifts on icy or slippery roads, be- cause engine braking may cause skidding and loss of control.

304 STARTING AND OPERATING

Hill Climbing

NOTE: Before attempting to climb a hill, determine the conditions at the crest and/or on the other side. Before climbing a steep hill, shift the transmission to a lower gear and shift the transfer case to 4WD LOW. Use first gear and 4WD LOW for very steep hills. If you stall or begin to lose forward motion while climbing a steep hill, allow your vehicle to come to a stop and immediately apply the brakes. Restart the engine, and shift into REVERSE. Back slowly down the hill, allowing the compression braking of the engine to help regulate your speed. If the brakes are required to control vehicle speed, apply them lightly and avoid locking or skidding the tires.

WARNING!

If the engine stalls, you lose forward motion, or cannot make it to the top of a steep hill or grade, never attempt to turn around. To do so may result in tipping and rolling the vehicle. Always back care- fully straight down a hill in REVERSE gear. Never back down a hill in NEUTRAL using only the brake.

Remember, never drive diagonally across a hill always drive straight up or down. If the wheels start to slip as you approach the crest of a hill, ease off the accelerator and maintain forward motion by turning the front wheels slowly. This may provide a fresh “bite” into the surface and will usually provide traction to complete the climb.

Traction Downhill Shift the transmission into a low gear, and the transfer case into 4WD LOW range. Let the vehicle go slowly down the hill with all four wheels turning against engine compression drag. This will permit you to control the vehicle speed and direction. When descending mountains or hills, repeated braking can cause brake fade with loss of braking control. Avoid repeated heavy braking by downshifting the transmis- sion whenever possible. After Driving Off-Road Off-road operation puts more stress on your vehicle than does most on-road driving. After going off-road, it is always a good idea to check for damage. That way you can get any problems taken care of right away and have your vehicle ready when you need it.

STARTING AND OPERATING 305

• Completely inspect the underbody of your vehicle. Check tires, body structure, steering, suspension, and exhaust system for damage. • Check threaded fasteners for looseness, particularly on the chassis, drivetrain components, steering, and sus- pension. Retighten them, if required, and torque to the values specified in the Service Manual. • Check for accumulations of plants or brush. These things could be a fire hazard. They might hide damage lines, brake hoses, axle pinion seals, and to fuel propeller shafts. • After extended operation in mud, sand, water, or similar dirty conditions, have brake rotors, wheels, brake linings, and axle yokes inspected and cleaned as soon as possible.

306 STARTING AND OPERATING

WARNING!

Abrasive material in any part of the brakes may cause excessive wear or unpredictable braking. You might not have full braking power when you need it to prevent an accident. If you have been operating your vehicle in dirty conditions, get your brakes checked and cleaned as necessary. • If you experience unusual vibration after driving in mud, slush or similar conditions, check the wheels for impacted material. Impacted material can cause a wheel imbalance and freeing the wheels of it will correct the situation.

POWER STEERING The standard power steering system will give you good vehicle response and increased ease of maneuverability in tight spaces. The system will provide mechanical steering capability if power assist is lost.

If for some reason the power assist is interrupted, it will still be possible to steer your vehicle. Under these condi- tions, you will observe a substantial increase in steering effort, especially at very low vehicle speeds and during parking maneuvers. Increased noise levels at the end of the steering NOTE: wheel travel are considered normal and do not indicate that there is a problem with the power steering system. Upon initial start-up in cold weather, the power steering pump may make noise for a short amount of time. This is due to the cold, thick fluid in the steering system. This noise should be considered normal, and it does not in any way damage the steering system.

WARNING!

WARNING!

STARTING AND OPERATING 307

Continued operation with reduced power steering assist could pose a safety risk to yourself and others. Service should be obtained as soon as possible.

CAUTION!

Prolonged operation of the steering system at the end of the steering wheel travel will increase the steering fluid temperature and it should be avoided when possible. Damage to the power steering pump may occur.

System Power

Do not use Automatic Transmission Fluid (ATF), or other types of power steering fluids, when servicing the power steering system of this vehicle. Damage to the power steering system can result from the use of the wrong power steering fluid.

Checking the power steering fluid level at a defined service interval is not required. The fluid should only be checked if a leak is suspected, abnormal noises are apparent, and/or the system is not functioning as antici- pated. Coordinate inspection efforts through an autho- rized dealer.

308 STARTING AND OPERATING

WARNING!

Fluid level should be checked on a level surface and with the engine off to prevent injury from moving parts and to ensure accurate fluid level reading. Do not overfill. Use only manufacturers recommended power steering fluid.

If necessary, add fluid to restore to the proper indicated level. With a clean cloth, wipe any spilled fluid from all surfaces.

PARKING BRAKE To set the parking brake, pull the lever up as firmly as possible. When the parking brake is applied with the ignition ON, the Brake Warning Light in the instrument cluster will light. To release the parking brake, pull up slightly, press the center button, then lower the lever completely.

NOTE: The Brake Warning Light indicates only that the parking brake is applied. It does not indicate the degree of brake application.

Be sure the parking brake is firmly set when parked, and the shift lever is in the PARK position. When parking on a hill, you should apply the parking brake before placing

the shift lever in PARK, otherwise the load on the transmission locking mechanism may make it difficult to move the shift lever out of PARK.

WARNING!

• Always fully apply the parking brake when leav- ing your vehicle, or it may roll and cause damage or injury. Also, be certain to leave the transmission in PARK. Failure to do so may allow the vehicle to roll and cause damage or injury. • Leaving unattended children in a vehicle is dan- gerous for a number of reasons. A child or others could be injured. Children should be warned not to touch the parking brake or the shift lever. Do not leave the key in the ignition. A child could operate power windows, other controls, or move the vehicle.

STARTING AND OPERATING 309

WARNING! (Continued)

• Be sure the parking brake is fully disengaged before driving, failure to do so can lead to brake problems due to excessive heating of the rear brakes.

When parking on a hill, turn the front wheels toward the curb on a downhill grade, and away from the curb on an uphill grade. The parking brake should always be applied whenever the driver is not in the vehicle.

ANTI-LOCK BRAKE SYSTEM The Anti-Lock Brake System (ABS) is designed to aid the driver in maintaining vehicle control under adverse braking conditions. The system operates with a separate computer to modulate hydraulic pressure, to prevent

310 STARTING AND OPERATING

lock-up and help avoid skidding on slippery

wheel surfaces. All vehicle wheels and tires must be the same size and type, and tires must be properly inflated, to produce accurate signals for the computer.

WARNING!

Significant over or under-inflation of tires or mixing sizes of tires or wheels on the vehicle can lead to loss of braking effectiveness.

The ABS conducts a low-speed self-test at about 12 mph (20 km/h). If you have your foot lightly on the brake while this test is occurring, you may feel slight pedal movement. The movement can be more apparent on ice and snow. This is normal.

The ABS pump motor runs during the self-test at 12 mph (20 km/h) and during an ABS stop. The pump motor makes a low humming noise during operation, which is normal.

WARNING!

• Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to an accident. Pumping makes the stopping distance longer. Just press firmly on your brake pedal when you need to slow down or stop. • The ABS cannot prevent the natural laws of phys- ics from acting on the vehicle, nor can it increase braking or steering efficiency beyond that af- forded by the condition of the vehicle brakes and tires or the traction afforded.

(Continued)

WARNING! (Continued) • The ABS cannot prevent accidents,

including those resulting from excessive speed in turns, following another vehicle too closely, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents. • The capabilities of an ABS equipped vehicle must never be exploited in a reckless or dangerous manner, which could jeopardize the user’s safety or the safety of others.

CAUTION!

The ABS is subject to possible detrimental effects of electronic interference caused by improperly in- stalled aftermarket radios or telephones.

STARTING AND OPERATING 311

NOTE: During severe braking conditions, a pulsing sensation may occur and a clicking noise will be heard. This is normal, indicating that the ABS is functioning. • Do not “ride” the brakes by resting your foot on the pedal. This could overheat the brakes and result in longer stopping dis- unpredictable braking action, tances, or brake damage. • When descending mountains or hills, repeated brak- ing can cause brake fade with loss of braking control. Avoid repeated heavy braking by downshifting the transmission or locking out overdrive whenever pos- sible. • Engines may idle at higher speeds during warm-up, which could cause rear wheels to spin and result in loss of vehicle control. Be especially careful while driving on slippery roads, in close-quarter maneuver- ing, parking, or stopping.

312 STARTING AND OPERATING

• Do not drive too fast for road conditions, especially when roads are wet or slushy. A wedge of water can build up between the tire tread and the road. This hydroplaning action can cause loss of traction, braking ability, and control. • After going through deep water or a car wash, brakes may become wet, resulting in decreased performance and unpredictable braking action. Dry the brakes by gentle, intermittent pedal action while driving at very slow speeds.

ELECTRONIC BRAKE CONTROL SYSTEM Your vehicle is equipped with an advanced electronic brake control system that includes ABS (Anti-Lock Brake System), TCS (Traction Control System), BAS (Brake Assist System), ERM (Electronic Roll Mitigation), and ESP (Electronic Stability Program). All five of these systems work together to enhance vehicle stability and control in various driving conditions.

Also, your vehicle is equipped with TSC (Trailer Sway Control) and, if it has 4WD with the NV245 two-speed transfer case, HSA (Hill Start Assist) and HDC (Hill Descent Control). ABS (Anti-Lock Brake System)

This system aids the driver in maintaining vehicle control under adverse braking conditions. The system controls hydraulic brake pressure to prevent wheel lock-up and help avoid skidding on slippery surfaces during braking. Refer to “Anti-Lock Brake System” in Section 5 of this manual.

WARNING!

ABS (Anti-Lock Brake System) cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. ABS cannot prevent accidents, in- cluding those resulting from excessive speed in turns, driving on very slippery surfaces, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ABS- equipped vehicle must never be exploited in a reck- less or dangerous manner which could jeopardize the user’s safety or the safety of others.

TCS (Traction Control System)

This system monitors the amount of wheel spin of each of the driven wheels. If wheel spin is detected, brake pressure is applied to the slipping wheel(s) and engine power is reduced to provide enhanced acceleration and

STARTING AND OPERATING 313

stability. A feature of the TCS system functions similar to a limited-slip differential and controls the wheel spin across a driven axle. If one wheel on a driven axle is spinning faster than the other, the system will apply the brake of the spinning wheel. This will allow more engine torque to be applied to the wheel that is not spinning. This feature remains active even if TCS and ESP are in either the “Partial Off” or “Full Off” modes. Refer to “ESP (Electronic Stability Program)” in this section for more information. BAS (Brake Assist System) The BAS is designed to optimize the vehicle’s braking capability during emergency braking maneuvers. The system detects an emergency braking situation by sens- ing the rate and amount of brake application and then applies optimum pressure to the brakes. This can help reduce braking distances. The BAS complements the anti-lock brake system (ABS). Applying the brakes very quickly results in the best BAS assistance. To receive the

314 STARTING AND OPERATING

benefit of the system, you must apply continuous brak- ing pressure during the stopping sequence (do not “pump” the brakes). Do not reduce brake pedal pressure unless braking is no longer desired. Once the brake pedal is released, the BAS is deactivated.

WARNING!

BAS (Brake Assist System) cannot prevent the natu- ral laws of physics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. BAS cannot prevent accidents, including those resulting from excessive speed in turns, driving on very slippery surfaces, or hydroplaning. Only a safe, attentive, and skillful driver can prevent acci- dents. The capabilities of a BAS-equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.

ERM (Electronic Roll Mitigation) This system anticipates the potential for wheel lift by monitoring the driver’s steering wheel input and the speed of the vehicle. When ERM determines that the rate of change of the steering wheel angle and vehicle speed are sufficient to potentially cause wheel it then applies the brake of the appropriate wheel and may also reduce engine power to lessen the chance that wheel lift will occur. ERM will only intervene during very severe or evasive driving maneuvers. ERM can only reduce the chance of wheel lift occurring during severe or evasive driving maneuvers. It cannot prevent wheel lift due to other factors such as road conditions, leaving the roadway or striking objects or other vehicles.

lift,

NOTE: Anytime the ESP system is in the “Full Off” mode, ERM is disabled. Refer to ESP (Electronic Stability Program) for a complete explanation of the available ESP modes.

WARNING!

Many factors, such as vehicle loading, road condi- tions and driving conditions, influence the chance that wheel lift or rollover may occur. ERM cannot prevent all wheel lift or rollovers, especially those that involve leaving the roadway or striking objects or other vehicles. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ERM-equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopar- dize the user’s safety or the safety of others.

STARTING AND OPERATING 315

ESP (Electronic Stability Program)

This system enhances directional control and stability of the vehicle under various driving conditions. ESP cor- rects for oversteering or understeering of the vehicle by applying the brake of the appropriate wheel to assist in counteracting the oversteer or understeer condition. En- gine power may also be reduced to help the vehicle maintain the desired path. ESP uses sensors in the vehicle to determine the vehicle path intended by the driver and compares it to the actual path of the vehicle. When the actual path does not match the intended path, ESP applies the brake of the appropri- ate wheel to assist in counteracting the oversteer or understeer condition. • Oversteer - when the vehicle is turning more than

appropriate for the steering wheel position.

316 STARTING AND OPERATING

• Understeer - when the vehicle is turning less than

appropriate for the steering wheel position.

The ESP/TCS Indicator Light located in the instrument cluster, starts to flash as soon as the tires lose traction and the ESP system becomes active. The ESP/TCS Indicator Light also flashes when TCS is active. If the ESP/TCS Indicator Light begins to flash during acceleration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing road conditions.

WARNING!

ESP (Electronic Stability Program) cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. ESP cannot prevent accidents, in- cluding those resulting from excessive speed in turns, driving on very slippery surfaces, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ESP- equipped vehicle must never be exploited in a reck- less or dangerous manner which could jeopardize the user’s safety or the safety of others.

The ESP system has three available operating modes in 4WD HIGH range, two available operating modes on 2WD vehicles, and one operating mode in 4WD LOW range.

High Range (4WD Models) or 2WD Models

On This is the normal operating mode for ESP in 4WD HIGH range and in 2WD vehicles. Whenever the vehicle is started or the transfer case (if equipped) is shifted from 4WD LOW range or NEUTRAL back to 4WD HIGH range, the ESP system will be in this “On” mode. This mode should be used for most driving situations. ESP should only be turned to “Partial Off” or “Full Off” mode for specific reasons as noted below. Partial Off This mode is entered by momentarily depressing the ESP OFF switch. When in ⬙Partial Off⬙ mode, the TCS portion of ESP, except for the “limited slip” feature described in the TCS section, has been disabled and the ESP/TCS Indicator Light will be illuminated. All other stability features of ESP function normally. This mode is intended to be used if the vehicle is in deep snow, sand, or gravel

STARTING AND OPERATING 317

conditions and more wheel spin than ESP would nor- mally allow is required to gain traction. To turn ESP on again, momentarily depress the ESP OFF switch. This will restore the normal “ESP On” mode of operation.

ESP OFF Switch

318 STARTING AND OPERATING

NOTE: To improve the vehicle’s traction when driving with snow chains, or starting off in deep snow, sand, or gravel, it may be desirable to switch to the “Partial Off” mode by pressing the ESP OFF switch. Once the situation requiring ESP to be switched to the “Partial Off” mode is overcome, turn ESP back on by momentarily depressing the ESP OFF switch. This may be done while the vehicle is in motion. Full Off (4WD Models Only) This mode is intended for off-highway or off-road use when ESP stability features could inhibit vehicle maneu- verability due to trail conditions. This mode is entered by depressing and holding the ESP OFF switch for five seconds when the vehicle is stopped and the engine is running. After five seconds, the ESP/TCS Indicator Light will illuminate, and the “ESP OFF” message will appear in the Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center (EVIC)” in Section 4 of this manual for more information.

In this mode, ESP and TCS, except for the “limited slip” feature described in the TCS section, are turned off until the vehicle reaches a speed of 40 mph (64 km/h). At 40 mph (64 km/h), the system returns to “Partial Off” mode, described above. When the vehicle speed drops below 35 mph (56 km/h), the ESP system shuts off. ESP is deactivated at low vehicle speeds so that it will not interfere with off-road driving, but ESP function returns to provide the stability feature at speeds above 40 mph (64 km/h). The ESP/TCS Indicator Light will always be illuminated when ESP is off. To turn ESP on again, momentarily depress the ESP OFF switch. This will restore the normal “ESP On” mode of operation. NOTE: The “ESP OFF” message will display, and the audible chime will sound, when the shift lever is placed in the PARK position from any other position, and then moved out of the PARK position. This will occur even if the message was previously cleared.

WARNING!

With the ESP switched off, the enhanced vehicle stability offered by ESP and ERM are unavailable. In an emergency evasive maneuver, the ESP and ERM systems will not engage to assist in maintaining stability. The “Full Off” ESP mode is intended for off-road use only.

4WD Low Range

Full Off This is the normal operating mode for ESP in 4WD LOW range. Whenever the vehicle is started in 4WD LOW range, or the transfer case (if equipped) is shifted from 4WD HIGH range or NEUTRAL to 4WD LOW range, the ESP system will be in this “Full Off” mode. In 4WD LOW range, ESP and TCS, except for the “limited slip” feature described in the TCS section, are turned off until the vehicle reaches a speed of 40 mph (64 km/h). At 40 mph

STARTING AND OPERATING 319

(64 km/h), the normal ESP stability function returns but TCS remains off. When the vehicle speed drops below 35 mph (56 km/h), the ESP system shuts off. ESP is deactivated at low vehicle speeds in 4WD LOW range so that it will not interfere with off-road driving but ESP function returns to provide the stability feature at speeds above 40 mph (64 km/h). The ESP/TCS Indicator Light will always be illuminated in 4WD LOW range when ESP is off. NOTE: The “ESP OFF” message will display, and the audible chime will sound, when the shift lever is placed in the PARK position from any other position, and then moved out of the PARK position. This will occur even if the message was previously cleared

320 STARTING AND OPERATING

WARNING!

With the ESP switched off, the enhanced vehicle stability offered by ESP and ERM are unavailable. In an emergency evasive maneuver, the ESP and ERM systems will not engage to assist in maintaining stability. The “Full Off” mode is intended for off- road use only.

TSC (Trailer Sway Control) TSC uses sensors in the vehicle to recognize an exces- sively swaying trailer and will take the appropriate actions to attempt to stop the sway. The system may reduce engine power and apply the brake of the appro- priate wheel(s) to counteract the sway of the trailer. TSC will become active automatically once an excessively swaying trailer is recognized. No driver action is re- quired. Note that TSC cannot stop all trailers from swaying. Always use caution when towing a trailer and

follow the trailer tongue weight recommendations. Refer to “Trailer Towing” in Section 5 of this manual. When TSC is functioning, the ESP/TCS Indicator Light will flash, the engine power may be reduced and you may feel the brakes being applied to individual wheels to attempt to stop the trailer from swaying. TSC is disabled when the ESP system is in the “Partial Off” or “Full Off” modes.

WARNING!

If TSC activates while driving, slow the vehicle down, stop at the nearest safe location, and adjust the trailer load to eliminate trailer sway.

HSA (Hill Start Assist) (4WD Models With NV245
Two–Speed Transfer Case Only) The HSA system is designed to assist the driver when starting a vehicle from a stop on a hill. HSA will maintain the level of brake pressure the driver applied for a short

period of time after the driver takes their foot off of the brake pedal. If the driver does not apply the throttle during this short period of time, the system will release brake pressure and the vehicle will roll down the hill. The system will release brake pressure in proportion to amount of throttle applied as the vehicle starts to move in the intended direction of travel. HSA Activation Criteria The following criteria must be met in order for HSA to activate: • Vehicle must be stopped. • Vehicle must be on a 8% grade or greater hill. • Gear selection matches vehicle uphill direction (i.e., vehicle facing uphill is in forward gear; vehicle back- ing uphill is in REVERSE gear).

STARTING AND OPERATING 321

HSA will work in REVERSE and all forward gears when the activation criteria have been met. The system will not activate if the vehicle is placed in NEUTRAL or PARK.

WARNING!

There may be situations on minor hills (i.e., less than 8%), with a loaded vehicle, or while pulling a trailer, when the system will not activate and slight rolling may occur. This could cause a collision with another vehicle or object. Always remember the driver is responsible for braking the vehicle.

Towing with HSA HSA will provide assistance when starting on a grade when pulling a trailer.

322 STARTING AND OPERATING

WARNING!

• If you use a trailer brake controller with your trailer, your trailer brakes may be activated and deactivated with the brake switch. If so, when the brake pedal is released there may not be enough brake pressure to hold the vehicle and trailer on a hill and this could cause a collision with another vehicle or object behind you. In order to avoid rolling down the hill while resuming acceleration, manually activate the trailer brake prior to releas- ing the brake pedal. Always remember the driver is responsible for braking the vehicle.

(Continued)

WARNING! (Continued)

• HSA is not a parking brake. If you stop the vehicle on a hill without putting the transmission in PARK and using the parking brake, it will roll down the hill and could cause a collision with another vehicle or object. Always remember to use the parking brake while parking on a hill, and that the driver is responsible for braking the vehicle.

HSA Off If you wish to turn off the HSA system, it can be done using the Customer Programmable Features in the Elec- tronic Vehicle Information Center (EVIC). Refer to “Elec- tronic Vehicle Information Center (EVIC)” in Section 4 of this manual.

HDC (Hill Descent Control) (4WD Models With NV245 Two–Speed Transfer Case Only) HDC maintains vehicle speed while descending hills during off-road driving situations and is available in 4WD LOW range only. To enable HDC (transfer case must be in 4WD LOW range), press the HDC switch. If the HDC switch is pressed when the vehicle is not in 4WD LOW range, the light in the switch will flash for five seconds and HDC will not be enabled.

STARTING AND OPERATING 323

Hill Descent Switch

When HDC is properly enabled, the message “HILL DESCENT CONTROL” will appear in the EVIC and the light in the switch will be illuminated. HDC will auto- matically apply the brakes to control downhill speed when necessary. HDC has the capability to sense terrain

324 STARTING AND OPERATING

and will only activate when the vehicle is descending a hill. It will usually not activate on level ground. The HDC speed may be adjusted by the driver to suit the driving conditions. The speed corresponds to the trans- mission gear selected. • 1st = 1 mph (1.6 km/h) • 2nd = 2.5 mph (4 km/h) • 3rd = 4 mph (6 km/h) • 4th = 5.5 mph (9 km/h) • 5th = 7.5 mph (12 km/h) • REVERSE = 1 mph (1.6 km/h) • NEUTRAL = 2.5 mph (4 km/h) • PARK = HDC will not function

HDC also has the capability to sense rough terrain, and will automatically adjust to a slightly slower set speed (about 0.3 mph (0.5 km/h) than normal. HDC operation can be overridden with brake application to slow the vehicle down below the HDC control speed. Conversely, if more speed is desired during HDC control, the accelerator pedal will increase vehicle speed in the usual manner. When either the brake or the accelerator is released, HDC will control the vehicle back to the origi- nal set speed. HDC is intended for low speed off-road driving only. At vehicle speeds above 30 mph (48 km/h), HDC will no longer function. When the vehicle speed drops below 30 mph (48 km/h), HDC function will automatically resume and the vehicle speed will return to the chosen set speed.

WARNING!

HDC is only intended to assist the driver in control- ling vehicle speed when descending hills. The driver must remain attentive to the driving conditions and is responsible for maintaining a safe vehicle speed.

ESP/BAS Warning Light And ESP/TCS Indicator Light

The malfunction indicator lamp for the ESP is combined with the BAS indicator. The ESP/ BAS Warning Light and the ESP/TCS Indicator Light in the instrument cluster both come on when the ignition switch is turned to the ON position. They should both go out with the engine running.

If the ESP/BAS Warning Light comes on con- tinuously with the engine running, a malfunc- tion has been detected in either the ESP or the BAS system, or both. If this light remains on

STARTING AND OPERATING 325

after several ignition cycles, and the vehicle has been driven several miles at speeds greater than 30 mph (48 km/h), see your authorized dealer as soon as possible to have the problem diagnosed and corrected. NOTE: • ⬙The ESP/TCS Indicator Light and the ESP/BAS Warning Light come on momentarily each time the ignition switch is turned ON. • Each time the ignition is turned ON, the ESP System • The ESP Control System will make buzzing or clicking sounds when it is active. This is normal; the sounds will stop when ESP becomes inactive following the maneuver that caused the ESP activation.

Tire Loading and Tire Pressure

Tire Placard Location NOTE: The proper cold tire inflation pressure is listed on the driver’s side B-Pillar. Tire and Loading Information Placard

Tire and Loading Information Placard

STARTING AND OPERATING 331

This placard tells you important information about the: 1) number of people that can be carried in the vehicle 2) total weight your vehicle can carry 3) tire size designed for your vehicle 4) cold tire inflation pressures for the front, rear, and spare tires. Loading The vehicle maximum load on the tire must not exceed the load carrying capacity of the tire on your vehicle. You will not exceed the tire’s load carrying capacity if you adhere to the loading conditions, tire size, and cold tire inflation pressures specified on the Tire and Loading Information placard and in the “Vehicle Loading” section of this manual. NOTE: Under a maximum loaded vehicle condition, gross axle weight ratings (GAWRs) for the front and rear

332 STARTING AND OPERATING

axles must not be exceeded. For further information on GAWRs, vehicle loading, and trailer towing, refer to “Vehicle Loading” in this section. To determine the maximum loading conditions of your vehicle, locate the statement “The combined weight of occupants and cargo should never exceed XXX lbs or XXX kg” on the Tire and Loading Information placard. The combined weight of occupants, cargo/luggage and trailer tongue weight (if applicable) should never exceed the weight referenced here. Steps for Determining Correct Load Limit 1. Locate the statement “The combined weight of occu- pants and cargo should never exceed XXX lbs or XXX kg” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.

3. Subtract the combined weight of the driver and pas- sengers from XXX lbs or XXX kg. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if “XXX” amount equals 1,400 lbs (635 kg) and there will be five 150 lb (68 kg) passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (295 kg) (since 5 x 150 = 750, and 1400 – 750 = 650 lbs [295 kg]). 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in step 4. 6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle.

NOTE: • The following table shows examples on how to calcu- late total load, cargo/luggage, and towing capacities of your vehicle with varying seating configurations and number and size of occupants. This table is for illustration purposes only and may not be accurate for the seating and load carry capacity of your vehicle.

STARTING AND OPERATING 333

• For the following example, the combined weight of occupants and cargo should never exceed 865 lbs (392 kg).

334 STARTING AND OPERATING

WARNING!

Safety

STARTING AND OPERATING 335

Overloading of your tires is dangerous. Overloading can cause tire failure, affect vehicle handling, and increase your stopping distance. Use tires of the recommended load capacity for your vehicle. Never overload them.

TIRES — GENERAL INFORMATION

Tire Pressure Proper tire inflation pressure is essential to the safe and satisfactory operation of your vehicle. Three primary areas are affected by improper tire pressure:

WARNING!

• Improperly inflated tires are dangerous and can cause accidents. • Underinflation increases tire flexing and can result in tire failure. • Overinflation reduces a tire’s ability to cushion shock. Objects on the road and chuckholes can cause damage that result in tire failure. • Unequal tire pressures can cause steering prob- lems. You could lose control of your vehicle. • Overinflated or underinflated tires can affect ve- hicle handling and can fail suddenly, resulting in loss of vehicle control.

(Continued)

336 STARTING AND OPERATING

WARNING! (Continued)

• Unequal tire pressures from one side of the vehicle to the other can cause the vehicle to drift to the right or left. • Always drive with each tire inflated to the recom- mended cold tire inflation pressure.

Economy Improper inflation pressures can cause uneven wear patterns to develop across the tire tread. These abnormal wear patterns will reduce tread life resulting in a need for earlier tire replacement. Underinflation also increases tire rolling resistance and results in higher fuel consumption. Ride Comfort and Vehicle Stability Proper tire inflation contributes to a comfortable ride. Overinflation produces a jarring and uncomfortable ride. Both underinflation and overinflation affect the stability

of the vehicle and can produce a feeling of sluggish response or over responsiveness in the steering. Unequal tire pressures can cause erratic and unpredict- able steering response. Unequal tire pressure from side to side may cause the vehicle to drift left or right. Tire Inflation Pressures The proper cold tire inflation pressure is listed on the driver’s side “B” Pillar. The pressure should be checked and adjusted, as well as inspected for signs of tire wear or visible damage, at least once a month. Use a good quality pocket-type gauge to check tire pressure. Do not make a visual judgement when determining proper inflation. Radial tires may look properly inflated even when they are underinflated.

CAUTION!

After inspecting or adjusting the tire pressure, al- ways reinstall the valve stem cap (if equipped). This will prevent moisture and dirt from entering the valve stem, which could damage it.

Inflation pressures specified on the placard are always cold tire inflation pressure. Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been driven for at least three hours, or driven less than 1 mile (1.6 km) after a three-hour period. The cold tire inflation pressure must not exceed the maximum inflation pres- sure molded into the tire sidewall. Check tire pressures more often if subject to a wide range of outdoor temperatures, as tire pressures vary with temperature changes.

STARTING AND OPERATING 337

Tire pressures change by approximately 1 psi (7 kPa) per 12°F (7°C) of air temperature change. Keep this in mind when checking tire pressure inside a garage, especially in the winter. Example: If garage temperature = 68°F (20°C) and the outside temperature = 32°F (0°C) then the cold tire inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this outside temperature condition. Tire pressure may increase from 2 to 6 psi (13 to 40 kPa) during operation. DO NOT reduce this normal pressure build-up, or your tire pressure will be too low. Tire Pressures For High Speed Operation The manufacturer advocates driving at safe speeds within posted speed limits. Where speed limits or condi- tions are such that the vehicle can be driven at high speeds, maintaining correct tire inflation pressure is very important. Increased tire pressure and reduced vehicle

338 STARTING AND OPERATING

loading may be required for high-speed vehicle opera- tion. Refer to original equipment or an authorized tire dealer for recommended safe operating speeds, loading and cold tire inflation pressures.

WARNING!

High speed driving with your vehicle at or above maximum load is dangerous. The added strain on your tires could cause them to fail. You could have a serious accident. Do not drive a vehicle loaded to the maximum capacity at continuous speeds above 75 mph (120 km/h).

Radial-Ply Tires

WARNING!

Combining radial ply tires with other types of tires on your vehicle will cause your vehicle to handle poorly. The instability could cause an accident. Al- ways use radial tires in sets of four. Never combine them with other types of tires.

Cuts and punctures in radial tires are repairable only in the tread area because of sidewall flexing. Consult your authorized dealer for radial tire repairs. Compact Spare Tire — If Equipped The compact spare is for temporary emergency use with radial tires. It is engineered to be used on your style vehicle only. Since this tire has limited tread life, the original tire should be repaired (or replaced) and rein- stalled at the first opportunity.

STARTING AND OPERATING 339

WARNING!

CAUTION!

Temporary use spare tires are for emergency use only. With these tires, do not drive more than 50 mph (80 km/h). Temporary use spare tires have limited tread life. When the tread is worn to the tread wear indicators, the temporary use spare tire needs to be replaced. Be sure to follow the warnings, which apply to your spare. Failure to do so could result in spare tire failure and loss of vehicle control.

Do not install a wheel cover or attempt to mount a conventional tire on the compact spare wheel, since the wheel is designed specifically for the compact spare. Do not install more than one compact spare tire/wheel on the vehicle at any given time.

Because of the reduced ground clearance, do not take your vehicle through an automatic car wash with the compact spare installed. Damage to the vehicle may result.

Limited-Use Spare — If Equipped The limited-use spare tire is for temporary emergency use on your vehicle. This tire is identified by a limited- use spare tire warning label located on the limited-use spare tire and wheel assembly. This tire may look like the original equipped tire on the front or rear axle of your vehicle, but it is not. Installation of this limited-use spare tire affects vehicle handling. Since it is not the same tire, replace (or repair) the original tire and reinstall on the vehicle at the first opportunity.

340 STARTING AND OPERATING

WARNING!

WARNING!

The limited-use spare tires are for emergency use only. Installation of this limited-use spare tire affects vehicle handling. With this tire, do not drive more than 50 mph (80 km/h). Keep inflated to the cold tire inflation pressure listed on either your tire placard or limited-use spare tire and wheel assembly. Replace (or repair) the original tire at the first opportunity and reinstall it on your vehicle. Failure to do so could result in loss of vehicle control.

Tire Spinning When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle’s wheels above 35 mph (55 km/h).

Fast spinning tires can be dangerous. Forces gener- ated by excessive wheel speeds may cause tire dam- age or failure. A tire could explode and injure some- one. Do not spin your vehicle’s wheels faster than 35 mph (55 km/h) when you are stuck, and do not let anyone near a spinning wheel no matter what the speed.

Tread Wear Indicators Tread wear indicators are in the original equipment tires to help you in determining when your tires should be replaced.

STARTING AND OPERATING 341

Many states have laws requiring tire replacement at this point. Life Of Tire The service life of a tire is dependent upon various factors including but not limited to: • Driving style • Tire pressure • Distance driven

WARNING!

Tires and the spare tire should be replaced after six years, regardless of the remaining tread. Failure to follow this warning can result in sudden tire failure. You could lose control and have an accident resulting in serious injury or death.

1 — Worn Tire 2 — New Tire

These indicators are molded into the bottom of the tread grooves. They will appear as bands when the tread depth becomes 1/16 in (2 mm). When the indicators appear in two or more adjacent grooves, the tire should be re- placed.

342 STARTING AND OPERATING

Keep dismounted tires in a cool, dry place with as little exposure to light as possible. Protect tires from contact with oil, grease, and gasoline. Replacement Tires The tires on your new vehicle provide a balance of many characteristics. They should be inspected regularly for wear and correct cold tire inflation pressure. The manu- facturer strongly recommends that you use tires equiva- lent to the originals in size, quality and performance when replacement is needed. (Refer to the paragraph on “Tread Wear Indicators”). Refer to the “Tire and Loading Information” placard for the size designation of your tires. The service description and load identification will be found on the original equipment tire. Failure to use equivalent replacement tires may adversely affect the safety, handling, and ride of your vehicle. We recommend that you contact your original equipment or an autho- rized tire dealer with any questions you may have on tire specifications or capability.

WARNING!

• Do not use a tire, wheel size or rating other than that specified for your vehicle. Some combinations of unapproved tires and wheels may change sus- pension dimensions and performance characteris- tics, resulting in changes to steering, handling, and braking of your vehicle. This can cause unpredict- able handling and stress to steering and suspen- sion components. You could lose control and have an accident resulting in serious injury or death. Use only the tire and wheel sizes with load ratings approved for your vehicle. • Never use a tire with a smaller load index or capacity than what was originally equipped on your vehicle. Using a tire with a smaller load index could result in tire overloading and failure. You could lose control and have an accident.

(Continued)

WARNING! (Continued)

• Failure to equip your vehicle with tires having adequate speed capability can result in sudden tire failure and loss of vehicle control.

CAUTION!

Replacing original tires with tires of a different size may result in false speedometer and odometer read- ings.

TIRE CHAINS Certain models have sufficient tire-to-body clearance to allow use of tire chains. Install chains on rear tires only. Follow these recommendations to guard against damage and excessive tire and chain wear:

STARTING AND OPERATING 343

• Do not install tire chains or traction devices on ve- hicles with larger than P235/65R17 tires. Tires larger than this may not provide sufficient body clearance with chains or other traction devices. • Use SAE class “S” tire chains or traction devices only. • Follow tire chain manufacturer’s instructions for • Install chains snugly and tighten after 0.5 mile (1 km) • Do not exceed 30 mph (48 km/h), unless otherwise • Drive cautiously, avoiding large bumps, potholes and

344 STARTING AND OPERATING

TIRE ROTATION RECOMMENDATIONS Tires on the front and rear axles of vehicles operate at different loads and perform different steering, handling, and braking functions. For these reasons, they wear at unequal rates and develop irregular wear patterns. The suggested rotation method is the “forward-cross” shown in the following diagram.

These effects can be reduced by timely rotation of tires. The benefits of rotation are especially worthwhile with aggressive tread designs such as those on On/Off-Road type tires. Rotation will increase tread life, help to main- tain mud, snow, and wet traction levels, and contribute to a smooth, quiet ride. Follow the recommended tire rotation frequency for your type of driving. Refer to “Maintenance Schedules” in Section 8 of this manual. More frequent rotation is permissible if desired. The reasons for any rapid or unusual wear should be corrected prior to rotation being performed. NOTE: The premium Tire Pressure Monitor System will automatically locate the pressure values displayed in the correct vehicle position following a tire rotation.

TIRE PRESSURE MONITOR SYSTEM (TPMS) The Tire Pressure Monitoring System (TPMS) will warn the driver of a low tire pressure based on the vehicle recommended cold tire pressure. The tire pressure will vary with temperature by about 1 psi (7 kPa) for every 12°F (–11°C). This means that when the outside temperature decreases, the tire pressure will decrease. Tire pressure should always be set based on cold inflation tire pressure. This is defined as the tire pressure after the vehicle has not been driven for at least three hours, or driven less than 1 mile (1 km) after a three-hour period. Refer to the “Tires – General Infor- mation” in this section for information on how to properly inflate the vehicle’s tires. The tire pressure will also increase as the vehicle is driven - this is normal and there should be no adjustment for this increased pres- sure.

STARTING AND OPERATING 345

The TPMS will warn the driver of a low tire pressure if the tire pressure falls below the low pressure warning threshold for any reason, including low temperature effects, or natural pressure loss through the tire. The TPMS will continue to warn the driver of low tire pressure as long as the condition exists, and will not turn off until the tire pressure is at or above recommended cold tire pressure. Once the low tire pressure warning has been illuminated, the tire pressure must be increased to the recommended cold tire pressure in order for the Tire Pressure Monitoring Telltale Light to be turned off. The system will automatically update and the Tire Pressure Monitoring Telltale Light will extinguish once the up- dated tire pressures have been received. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) to receive this information.

346 STARTING AND OPERATING

For example, your vehicle has a recommended cold (parked for more than three hours) tire pressure of 33 psi (227 kPa). If the ambient temperature is 68°F (20°C) and the measured tire pressure is 28 psi (193 kPa), a tempera- ture drop to 20°F (-7°C) will decrease the tire pressure to approximately 24 psi (165 kPa). This tire pressure is sufficiently low enough to turn ON the Tire Pressure Monitoring Telltale Light. Driving the vehicle may cause the tire pressure to rise to approximately 28 psi (193 kPa), but the Tire Pressure Monitoring Telltale Light will still be ON. In this situation, the Tire Pressure Monitoring Telltale Light will turn OFF only after the tires have been inflated to the vehicle’s recommended cold tire pressure value.

CAUTION!

• The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size, type, and/or style. Aftermarket wheels can cause sensor dam- age. Do not use aftermarket tire sealants or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result. • After inspecting or adjusting the tire pressure always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the Tire Pressure Moni- toring Sensor.

while adjusting your tire pressure.

NOTE: • The TPMS is not intended to replace normal tire care and maintenance, or to provide warning of a tire failure or condition. • The TPMS should not be used as a tire pressure gauge • Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. • The TPMS is not a substitute for proper tire mainte- nance, and it is the driver’s responsibility to maintain correct tire pressure using an accurate tire gauge, even if under-inflation has not reached the level to trigger illumination of the Tire Pressure Monitoring Telltale Light.

STARTING AND OPERATING 347

• Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.

Base System The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim-mounted electronic sensors to monitor tire pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to the Receiver Module. It is particularly important, for you to regularly NOTE: check the tire pressure in all of your tires, and to maintain the proper pressure. The TPMS consists of the following components: • Receiver Module • Four Tire Pressure Monitoring Sensors • Tire Pressure Monitoring Telltale Light

348 STARTING AND OPERATING

A tire pressure monitoring sensor is located in the spare wheel, if the vehicle is equipped with a matching full-size spare wheel and tire assembly. The matching full-size spare tire can be used in place of any of the four road tires. A low spare tire will not cause the Tire Pressure Monitoring Telltale Light to illuminate, a warning mes- sage to appear, or the chime to sound.

The Tire Pressure Monitoring Telltale Light will illuminate in the instrument cluster, a “TIRE LOW PRESSURE” message will display in the instru- ment cluster for 60 seconds, and an audible chime will be activated, when one or more of the four active road tire pressures are low. Should this occur, you should stop as soon as possible, check the inflation pressure of each tire on your vehicle, and inflate each tire to the vehicle’s recommended cold placard pressure value. The system will automatically update and the Tire Pressure Monitor- ing Telltale Light will extinguish, once the updated tire

pressures have been received. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) to receive this information. The Tire Pressure Monitoring Telltale Light will flash on and off for 75 seconds, and remain on solid when a system fault is detected. In addition, a “CHECK TPM SYSTEM” message will be displayed for 75 seconds when a system fault is detected, and a chime will sound. If the ignition key is cycled, this sequence will repeat, provid- ing the system fault still exists. The Tire Pressure Moni- toring Telltale Light will turn off when the fault condition no longer exists. A system fault can occur by any of the following: 1. Jamming due to electronic devices or driving next to facilities emitting the same Radio Frequencies as the TPM sensors. 2. Installing some form of aftermarket window tinting that affects radio wave signals.

3. Lots of snow or ice around the wheels or wheel housings. 4. Using tire chains on the vehicle. 5. Using wheels/tires not equipped with TPM sensors. NOTE: • If your vehicle is equipped with a matching full-size spare wheel and tire assembly, it has a tire pressure monitoring sensor, and can be monitored by the Tire Pressure Monitoring System (TPMS). In the event that the matching full-size spare tire is swapped with a low pressure road tire, the next ignition key cycle will still show the Tire Pressure Monitoring Telltale Light to be ON, a “TIRE LOW PRESSURE” message will be displayed in the instrument cluster for 60 seconds, and a chime to sound. Driving the vehicle for up to 20 minutes above 15 mph (24 km/h) will turn OFF the

STARTING AND OPERATING 349

Tire Pressure Monitoring Telltale Light as long as none of the road tires are below the low pressure warning threshold. • If your vehicle is not equipped with a matching full-size spare wheel and tire assembly, it does not have a tire pressure monitoring sensor in the spare tire. The TPMS will not be able to monitor the tire pressure. If you install the spare tire, in place of a road tire, that has a pressure below the low-pressure warning limit, upon the next ignition key cycle, a chime will sound, a “TIRE LOW PRESSURE” message will be displayed in the instrument cluster for 60 seconds, and the Tire Pressure Monitoring Telltale Light will turn ON. After driving the vehicle for up to 20 minutes above 15 mph (25 km/h), the Tire Pressure Monitoring Telltale Light will flash on and off for 75 seconds and then remain on solid. In addition, a “CHECK TPM SYSTEM” message will be displayed for 75 seconds. For each subsequent ignition key cycle, a chime will sound, a “CHECK

350 STARTING AND OPERATING

TPM SYSTEM” message will be displayed for 75 sec- onds, and the Tire Pressure Monitoring Telltale Light will flash on and off for 75 seconds and then remain on solid. Once you repair or replace the original road tire, and reinstall it on the vehicle in place of the spare tire, the TPMS will update automatically and the Tire Pressure Monitoring Telltale Light will turn OFF, as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) in order for the TPMS to receive this information.

Premium System — If Equipped The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim-mounted electronic sensors to monitor tire pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to the Receiver Module.

The Tire Pressure Monitoring Telltale Light will illuminate in the instrument cluster, and an au- dible chime will be activated, when one or more of the four active road tire pressures are low. In addition, the EVIC will display one or more Low Pressure messages (Left Front, Left Rear, Right Front, Right Rear) for three seconds, and a graphic display of the pressure value(s) with the low tire(s) “flashing.” Refer to “Electronic Ve- hicle Information Center (EVIC)” in Section 4 of this manual. NOTE: Your system can be set to display pressure units in PSI, kPa, or BAR.
