• Passenger Temperature Control
Rotate this control to regulate the tem- perature of the air inside the passenger compartment for the right front seat occupant. Rotating the dial left into the blue area of the scale indicates cooler temperatures, while rotating right into the red area indicates warmer temperatures. If your air conditioning performance seems NOTE: lower than expected, check the front of the A/C con- denser located in front of the radiator for an accumula- tion of dirt or insects. Clean with a gentle water spray from behind the radiator and through the condenser. Fabric front fascia protectors may reduce airflow to the condenser, reducing air conditioning performance.
396 UNDERSTANDING YOUR INSTRUMENT PANEL Mode Control (Air Direction) Push the mode control buttons to choose from several patterns of air distribution. Panel
Air is directed through the outlets in the instrument panel. These outlets can be adjusted to direct airflow. NOTE: The center instrument panel outlets can be aimed so that they are directed toward the rear seat passengers for maximum airflow to the rear. Bi-Level
Air is directed through the panel and floor outlets.
NOTE: For all settings, except full cold or full hot, there is a difference in temperature between the upper and lower outlets. The warmer air flows to the floor outlets. This feature gives improved comfort during sunny but cool conditions.
Floor
Air is directed through the floor outlets with a small amount flowing through the defrost and side
window demist outlets. Mix
Air is directed through the floor, defrost, and side window demist outlets. This setting works best in cold or snowy conditions that require extra heat to the windshield. This setting is good for maintaining comfort while reducing moisture on the windshield. Defrost
Air is directed through the windshield and side window demist outlets. Use this mode with maxi- mum blower and temperature settings for best wind- shield and side window defrosting.
NOTE: • In Floor, Mix and Defrost modes a small amount of air will flow through the outboard panel outlets for occupant comfort. • The air conditioning compressor operates in Mix, Defrost, or a blend of these modes, even if the Air Conditioning (A/C) button is not pressed. This dehu- midifies the air to help dry the windshield. To improve fuel economy, use these modes only when necessary.
Recirculation Control
Pressing the Recirculation Control button will put the system in recirculation mode. This can be used when outside conditions such as smoke, odors, dust, or high humidity are pres- ent. Activating recirculation will cause the LED in the control button to illuminate.

3. When the system is set up for your comfort level, it is not necessary to change the settings. You will experience the greatest efficiency by simply allowing the system to function automatically. NOTE: • It is not necessary to move the temperature settings for cold or hot vehicles. The system automatically adjusts the temperature, mode and fan speed to provide comfort as quickly as possible. • The temperature can be displayed in U.S. or Metric units by selecting the US/M customer-programmable feature. Refer to the “Electronic Vehicle Information Center (EVIC) — Customer-Programmable Features (SETUP)” in this section of the manual.To provide you with maximum comfort in the Automatic mode, during cold start-ups the blower fan will remain on low until the engine warms up. The blower will increase in speed and transition into Auto mode.
402 UNDERSTANDING YOUR INSTRUMENT PANEL Manual Operation This system offers a full complement of manual override features. NOTE: Each of these features operate independently from each other. If any one feature is controlled manually, temperature control will continue to operate automati- cally.
There are seven fixed blower speeds. Use the outer dial control to regulate the amount of air forced through the system in any mode you select. The blower speed increases as you move the control clockwise and decreases when you move the control counter- clockwise.
Blower Control
The blower fan speed can be set to any fixed speed by adjusting the blower control outer dial. The fan will now operate at a fixed speed until additional speeds are selected. This allows the front occupants to control the volume of air circulated in the vehicle and cancel the Auto mode. The operator can also select the direction of the airflow by selecting one of the following positions. Panel Mode
Air comes from the outlets in the instrument panel. Each of these outlets can be individually adjusted to direct the flow of air. The air vanes of the center outlets and outboard outlets can be moved up and down or side to side to regulate airflow direction. There is a shut off wheel located below the air vanes to shut off or adjust the amount of airflow from these outlets.
Bi-Level Mode
Air comes from the instrument panel outlets, floor outlets and defrost outlets.
In many temperature positions, the BI-LEVEL NOTE: mode is designed to provide cooler air out of the panel outlets and warmer air from the floor outlets. Floor Mode
Air comes from the floor outlets. A slight amount of air is directed through the defrost and side window
demister outlets. Mix Mode
Air comes from the floor, defrost and side window demist outlets. This mode works best in cold or snowy conditions. It allows you to stay comfortable
while keeping the windshield clear.
UNDERSTANDING YOUR INSTRUMENT PANEL 403
Defrost Mode
Air comes from the windshield and side window demist outlets. Use Defrost mode with maximum temperature settings for best windshield and side win- dow defrosting. When the defrost mode is selected, the blower will automatically default to medium-high unless the blower is controlled manually. NOTE: While operating in the other modes, the system will not automatically sense the presence of fog, mist or ice on the windshield. Defrost mode must be manually selected to clear the windshield and side glass. Air Conditioning (A/C) The Air Conditioning (A/C) button allows the operator to manually activate or deactivate the air conditioning system. When in A/C mode and the ATC is set to a cool temperature, dehumidified air flows through the air
404 UNDERSTANDING YOUR INSTRUMENT PANEL outlets. If Economy mode is desired, press the A/C button to turn off the A/C mode in the ATC display and deactivate the A/C system. NOTE: • If the system is in Mix, Floor or Defrost Mode, the A/C can be turned off, but the A/C system shall remain active to prevent fogging of the windows. • If fog or mist appears on the windshield or side glass,
select Defrost mode and increase blower speed.
Recirculation Control
When outside air contains smoke, odors, or high humidity, or if rapid cooling is desired, you may wish to recirculate interior air by pressing the Recirculation control button. Re- circulation mode should only be used temporarily. The recirculation LED will illuminate when this button is
selected. Push the button a second time to turn off the Recirculation mode LED and allow outside air into the vehicle. In cold weather, use of Recirculation mode may NOTE: lead to excessive window fogging. The Recirculation mode is not allowed in the Defrost mode to improve window clearing operation. Recirculation will be dis- abled automatically if this mode is selected. Operating Tips
Window Fogging Windows will fog on the inside when the humidity inside the vehicle is high. This often occurs in mild or cool temperatures when it’s rainy or humid. In most cases, turning the air conditioning (pressing the A/C button) on will clear the fog. Adjust the temperature control, air direction, and blower speed to maintain comfort.
As the temperature gets colder, it may be necessary to direct air onto the windshield. Adjust the temperature control and blower speed to maintain comfort. Higher blower speeds will reduce fogging. Interior fogging on the windshield can be quickly removed by selecting the Defrost mode. Regular cleaning of the inside of the windows with a non-filming cleaning solution (vinegar and water works very well) will help prevent contaminates (cigarette smoke, perfumes, etc.) from sticking to the windows. Contaminates increase the rate of window fogging. Summer Operation
In some cases during high temperature trailer NOTE: tow operation the Air Conditioning system performance may be reduced. This is to help protect the engine from overheating during the high load condition.
UNDERSTANDING YOUR INSTRUMENT PANEL 405
Your air conditioning system is also equipped with an automatic recirculation system. When the system senses a heavy load or high heat conditions, it may use partial Recirculation A/C mode to provide additional comfort. Winter Operation When operating the system during the winter months, make sure the air intake, located directly in front of the windshield, snow, or other obstructions. Vacation Storage Anytime you store your vehicle, or keep it out of service (i.e. vacation) for two weeks or more, run the air condi- tioning system at idle for about five minutes in the fresh air and high blower setting. This will ensure adequate system lubrication to minimize the possibility of com- pressor damage when the system is started again.free of

• Never pour fuel or other flammable liquids into the throttle body air inlet opening in an attempt to start the vehicle. This could result in a flash fire causing serious personal injury. • Do not attempt to push or tow your vehicle to get it started. Vehicles equipped with an automatic trans- mission cannot be started this way. Unburned fuel could enter the catalytic converter and once the engine has started, ignite and damage the converter and vehicle. If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or the battery in another vehicle. This type of start can be dangerous if done improp- erly. Refer to “Jump Starting” in “What To Do In Emergencies” for further information.

WARNING! (Continued)
• Children should be warned not to touch the park- ing brake, brake pedal or the shift lever. Do not leave the key fob in or near the vehicle, and do not leave Keyless Enter-N-Go in the ACC or ON/RUN mode. A child could operate power windows, other controls, or move the vehicle.
Key Ignition Park Interlock This vehicle is equipped with a Key Ignition Park Inter- lock which requires the shift lever to be placed in PARK before the ignition switch can be turned to the LOCK/ OFF position. The key fob can only be removed from the ignition when the ignition is in the LOCK/OFF position and once removed the shift lever is locked in PARK. Brake/Transmission Shift Interlock System This vehicle is equipped with a Brake Transmission Shift Interlock System (BTSI) that holds the shift lever in the

PARK position unless the brakes are applied. To move the shift lever out of the PARK position, the ignition switch must be turned to the ON/RUN position (engine running or not) and the brake pedal must be pressed. Five-Speed Automatic Transmission (3.6L Engine) — If Equipped The shift lever position display (located in the instrument panel cluster) indicates the transmission gear range. You must press the brake pedal to move the shift lever out of the PARK position (refer to “Brake/Transmission Shift Interlock System” in this section). To drive, move the shift lever from PARK or NEUTRAL to the DRIVE position. 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).422 STARTING AND OPERATING Shifting from DRIVE to PARK or REVERSE should be done only after the accelerator pedal is released and the vehicle is stopped. Be sure to keep your foot on the brake pedal when moving the shift lever between these gears. The transmission shift lever has only PARK, REVERSE, NEUTRAL, and DRIVE shift positions. Manual down- shifts can be made using the Electronic Range Select (ERS) shift control (refer to “Electronic Range Select (ERS)” in this section). Moving the shift lever to the left or right (-/+) while in the DRIVE position will select the highest available transmission gear, and will display that gear in the instrument cluster as 4, 3, 2, 1.
Shift Lever
Gear Ranges DO NOT race the engine when shifting from PARK or NEUTRAL into another gear range.
PARK This range supplements the parking brake by locking the transmission. The engine can be started in this range. Never attempt to use PARK while vehicle is in motion. Apply the parking brake when leaving vehicle in this range. When parking on a level surface, you may place the shift lever in the PARK position first, and then apply the parking brake. When parking on a hill, 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. As an added precau- tion, turn the front wheels toward the curb on a downhill grade and away from the curb on an uphill grade.
STARTING AND OPERATING 423
WARNING!
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully when parked to guard against vehicle movement and possible injury or damage. • Your vehicle could move and injure you and others if it is not completely in PARK. Check by trying to move the shift lever rearward (with the brake pedal released), after you have placed it in PARK. Make sure the transmission is in PARK before leaving the vehicle.

STARTING AND OPERATING 425
CAUTION!
• Before moving the shift lever out of PARK, you must turn the ignition switch from the LOCK/OFF position to the ON/RUN position, and also press the brake pedal. Otherwise, damage to the shift lever could result. • DO NOT race the engine when shifting from PARK or NEUTRAL into another gear range, as this can damage the drivetrain.
The following indicators should be used to ensure that you have engaged the shift lever into the PARK position: • When shifting into PARK, move the shift lever all the way forward and to the left until it stops and is fully seated. • Look at the shift lever position display and verify that
it indicates the PARK position.
426 STARTING AND OPERATING
• With brake pedal released, verify that the shift lever
will not move out of PARK.
REVERSE This range is for moving the vehicle backward. Shift into REVERSE only after the vehicle has come to a complete stop. NEUTRAL Use this range when the vehicle is standing for prolonged periods with engine running. The engine may be started in this range. Set the parking brake and shift the trans- mission into PARK if you must leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the ignition to coast down a hill. These are unsafe practices that limit your response to changing traffic or road conditions. You might lose control of the vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other reason with the transmission in NEUTRAL can result in severe transmission damage. Refer to “Recre- ational Towing” in “Starting And Operating” and “Towing A Disabled Vehicle” in “What To Do In Emergencies” for further information.
DRIVE This range should be used for most city and highway driving. It provides the smoothest upshifts and down- shifts, and the best fuel economy. The transmission automatically upshifts through underdrive first, second, and third gears, direct fourth gear and overdrive fifth gear. The DRIVE position provides optimum driving characteristics under all normal operating conditions. When frequent transmission shifting occurs (such as when operating the vehicle under heavy loading condi- tions, in hilly terrain, traveling into strong head winds, or while towing heavy trailers), use the Electronic Range Select (ERS) feature (refer to “Electronic Range Select (ERS)” in this section) to select a lower gear range. Under these conditions, using a lower gear range will improve performance and extend transmission life by reducing excessive shifting and heat buildup.
STARTING AND OPERATING 427
Transmission Limp Home Mode Transmission function is monitored electronically for abnormal conditions. If a condition is detected that could result in transmission damage, Transmission Limp Home Mode is activated. In this mode, the transmission remains in the current gear until the vehicle is brought to a stop. After the vehicle has stopped, the transmission will remain in second gear regardless of which forward gear is selected. PARK, REVERSE, and NEUTRAL will con- tinue to operate. The Malfunction Indicator Light (MIL) may be illuminated. Limp Home Mode allows the vehicle to be driven to an authorized dealer for service without damaging the transmission. In the event of a momentary problem, the transmission can be reset to regain all forward gears by performing the following steps: 1. Stop the vehicle. 2. Shift the transmission into PARK.
428 STARTING AND OPERATING 3. Turn the ignition switch to the LOCK/OFF position. 4. Wait approximately 10 seconds. 5. Restart the engine. 6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to normal operation. NOTE: Even if the transmission can be reset, we recom- mend that you visit your authorized dealer at your earliest possible convenience. Your authorized dealer has diagnostic equipment to determine if the problem could recur. If the transmission cannot be reset, authorized dealer service is required.
Electronic Range Select (ERS) Operation The Electronic Range Select (ERS) shift control allows the driver to limit the highest available gear when the shift lever is in the DRIVE position. For example, if you shift the transmission into 3 (third gear), the transmission will never shift above third gear, but will shift down into second and first gear normally. You can switch between DRIVE and ERS mode at any vehicle speed. When the shift lever is in the DRIVE position, the transmission will operate automatically, shifting between all available gears. Tapping the shift lever to the left (-) will downshift the transmission, activate ERS mode, display the current gear in the instrument cluster, and maintain that gear as the top available gear. Once in ERS mode, tapping the shift lever to the left (-) or right (+) will change the top available gear.
To exit ERS mode, simply press and hold the shift lever to the right (+) until “D” is once again displayed in the shift lever position indicator in the instrument cluster.
WARNING!
Do not downshift for additional engine braking on a slippery surface. The drive wheels could lose their grip and the vehicle could skid, causing an accident or personal injury.

REVERSE This range is for moving the vehicle backward. Shift into REVERSE only after the vehicle has come to a complete stop. NEUTRAL Use this range when the vehicle is standing for prolonged periods with engine running. The engine may be started in this range. Set the parking brake and shift the trans- mission into PARK if you must leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the ignition to coast down a hill. These are unsafe practices that limit your response to changing traffic or road conditions. You might lose control of the vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other reason with the transmission in NEUTRAL can result in severe transmission damage. Refer to “Recre- ational Towing” in “Starting And Operating” and “Towing A Disabled Vehicle” in “What To Do In Emergencies” for further information.
DRIVE This range should be used for most city and highway driving. It provides the smoothest upshifts and down- shifts, and the best fuel economy. The transmission automatically upshifts through underdrive first and sec- ond gears, direct third gear and overdrive fourth and fifth gears. The DRIVE position provides optimum driv- ing characteristics under all normal operating conditions. To access all six available gears, you must use the Electronic Range Select (ERS) feature (refer to “Electronic Range Select (ERS)” in this section). When frequent transmission shifting occurs (such as when operating the vehicle under heavy loading condi- tions, in hilly terrain, traveling into strong head winds, or while towing heavy trailers), use the Electronic Range Select (ERS) feature (refer to “Electronic Range Select (ERS)” in this section) to select a lower gear range. Under
STARTING AND OPERATING 435
these conditions, using a lower gear range will improve performance and extend transmission life by reducing excessive shifting and heat buildup. If the transmission operating temperature exceeds nor- mal operating limits, the powertrain controller will modify the transmission shift schedule and expand the range of torque converter clutch engagement. This is done to prevent transmission damage due to overheat- ing. If the transmission becomes extremely hot, the “Trans- mission Temperature Warning Light” may illuminate and the transmission may downshift out of Overdrive until the transmission cools down. NOTE: Use caution when operating a heavily loaded vehicle at low speeds (such as towing a trailer up a steep grade, or in stop-and-go traffic) during hot weather. In these conditions, torque converter slip can impose a significant additional heat load on the cooling system.436 STARTING AND OPERATING Downshifting the transmission to the lowest possible gear (when climbing a grade), or shifting to NEUTRAL (when stopped in heavy traffic) can help to reduce this excess heat generation. During cold temperatures, transmission operation may be modified depending on engine and transmission temperature as well as vehicle speed. This feature im- proves warm up time of the engine and transmission to achieve maximum efficiency. Engagement of both the torque converter clutch and the top overdrive gear are inhibited until the transmission fluid is warm (refer to the “Note” under “Torque Converter Clutch” in this section). During extremely cold temperatures (-16°F [-27°C] or below), operation may briefly be limited to first and direct gears only. Normal operation will resume once the transmission temperature has risen to a suitable level.
Transmission Limp Home Mode Transmission function is monitored electronically for abnormal conditions. If a condition is detected that could result in transmission damage, Transmission Limp Home Mode is activated. In this mode, the transmission remains in third gear regardless of which forward gear is selected. PARK, REVERSE, and NEUTRAL will continue to oper- ate. The Malfunction Indicator Light (MIL) may be illu- minated. Limp Home Mode allows the vehicle to be driven to an authorized dealer for service without dam- aging the transmission. In the event of a momentary problem, the transmission can be reset to regain all forward gears by performing the following steps: 1. Stop the vehicle. 2. Shift the transmission into PARK. 3. Turn the ignition switch to the LOCK/OFF position.
4. Wait approximately 10 seconds. 5. Restart the engine. 6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to normal operation.

the transmission into 3 (third gear), the transmission will never shift above third gear, but will shift down into second and first gear normally. 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 can improve vehicle performance and cooling capability when towing a trailer on certain grades. In ERS mode, gears 1 though 3 are underdrive gears, and ERS 4 is direct drive. ERS 5 and 6 (Overdrive gears ) are the same as the normal fourth and fifth gears. You can switch between DRIVE and ERS mode at any vehicle speed. When the shift lever is in the DRIVE position, the transmission will operate automatically, shifting between all available gears. Tapping the shift lever to the left (-) will activate ERS mode, display the current gear in the instrument cluster, and maintain that438 STARTING AND OPERATING gear as the top available gear.

When To Use TOW/HAUL Mode When driving in hilly areas, towing a trailer, carrying a heavy load, etc., and frequent transmission shifting oc- curs, press the TOW/HAUL switch to select TOW/ HAUL mode. This will improve performance and reduce the potential for transmission overheating or failure due to excessive shifting. When operating in TOW/HAUL mode, transmission upshifts are delayed, and the trans- mission will automatically downshift (for engine brak- ing) during steady braking maneuvers.

TOW/HAUL Switch
The “TOW/HAUL Indicator Light” will illuminate in the instrument cluster to indicate that TOW/HAUL mode has been 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.
440 STARTING AND OPERATING 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 calibrated speeds. This may result in a slightly different feeling or response during normal operation in the upper gears. When the vehicle speed drops or during some accelerations, the clutch automatically disengages. NOTE: • The torque converter clutch will not engage, and the transmission will not shift into the top overdrive gear, until the transmission fluid and engine coolant are warm [usually after 1 to 3 miles (1.6 to 4.8 km) of driving]. Because top gear is disabled, and engine speed is higher when the torque converter clutch is not engaged, it may seem as if the transmission is not shifting properly when cold. This is normal. Using the
Electronic Range Select (ERS) feature, when the trans- mission is sufficiently warm, will demonstrate that the transmission is able to shift into and out of Overdrive. • If the vehicle has not been driven for 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 after starting the engine.
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 (BTC) System, 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 “Starting and Oper- ating” for further information. Quadra-Trac II姞 Operating Instructions/ Precautions – If Equipped The Quadra-Trac II威 transfer case is fully automatic in the normal driving 4WD AUTO mode. The Quadra-Trac II威 transfer case provides three mode positions: • 4WD HI • NEUTRAL • 4WD LOW This transfer case is fully automatic in the 4WD HI mode.
STARTING AND OPERATING 441
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). 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.442 STARTING AND OPERATING
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.
Shift Positions
For additional information on the appropriate use of each transfer case mode position, see the information below: 4WD AUTO This range is used on surfaces such as ice, snow, gravel, sand, and dry hard pavement.
NOTE: Refer to “Selec-Terrain威 – If Equipped” in “Start- ing and Operating” for further information on the vari- ous positions and their intended usages. NEUTRAL This range disengages both the front and rear driveshafts from the powertrain. It is to be used for flat towing behind another vehicle. Refer to “Recreational Towing” in “Starting and Operating” for further information. 4WD LOW This range is for low speed four-wheel drive. It locks the front and rear driveshafts together and forces the front and rear wheels to rotate at the same speed. It provides additional traction and maximum pulling power for loose, slippery road surfaces only. Do not exceed 25 mph (40 km/h). NOTE: Refer to “Selec-Terrain威 – If Equipped” for further information on the various positions and their intended usages.
Shifting Procedures
4WD HI To 4WD LOW With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the ON position or the engine running, shift the transmission into NEUTRAL, and press the “4WD LOW” button once on the transfer case switch. The “4WD LOW” indicator light in the instrument cluster will begin to flash and remain on solid when the shift is complete.
STARTING AND OPERATING 443
Transfer Case Switch
If shift conditions/interlocks are not met, or a NOTE: transfer case motor temperature protection condition ex- ists, a “For 4x4 Low Slow Below 3 MPH or 5 KPH Put Trans in N Press 4 Low” message will flash from the Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center (EVIC)” in “Under- standing Your Instrument Panel” for further information.
444 STARTING AND OPERATING 4WD LOW To 4WD HI With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the ON position or the engine running, shift the transmission into NEUTRAL, and press the “4WD LOW” button once on the transfer case switch. The “4WD LOW” indicator light in the instrument cluster will flash and go out when the shift is complete. NOTE: • If shift conditions/interlocks are not met, or a transfer case motor temperature protection condition exists, a “For 4x4 High Slow Below 3 MPH or 5 KPH Put Trans in N Press 4 Low” message will flash from the Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center (EVIC)” in “Understanding Your Instrument Panel” for further information. • 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.
NEUTRAL Shift Procedure 1. Turn the ignition switch to the ON position, engine off. 2. Vehicle stopped, with foot on brake. 3. Place the transmission into NEUTRAL. 4. Hold down the NEUTRAL “pin” switch (with a pen, etc.) for four seconds until the LED light by the switch starts to blink indicating shift in progress. The light will stop blinking (stay on solid) when the NEUTRAL shift is complete.

The optional ELSD axle is fully automatic and requires no driver input to operate. Under normal driving conditions, the unit functions as a standard axle, balancing torque evenly between 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 coupling differ in design, their operation is similar. Follow the Quadra-Trac II威 transfer case shifting information, preceding this section, for shifting this system.Neutral Switch

Selec-Terrain™ Switch
Selec-Terrain™ consists of the following positions: • Sport – Dry weather, on-road calibration. Only avail- able in 4WD High range. Performance based tuning that provides a rear wheel drive feel but with im- proved handling and acceleration over a two-wheel drive vehicle. The Electronic Stability Control will set to allow more driver control of vehicle while maintain- ing safe handling controls. The vehicle will lower (if equipped with Air Suspension) to Aero Mode in High Range. 4WD Low is not available in SPORT mode, if 4WD Low is selected the Selec-Terrain™ will auto- matically switch back to AUTO. • Snow – Tuning set for additional stability in inclement weather. Use on and off road on loose traction surfaces such as snow. When in Snow mode (depending on certain operating conditions), the transmission may use second gear (rather than first gear) during launches, to minimize wheel slippage. If equipped

While in OR2, if the vehicle speed exceeds 25 mph (40 km/h) the vehicle height will be automatically lowered to OR1. Refer to “Off-Road Driving Tips” in “Starting and Operating” for further information. • Aero Mode (Lowers the vehicle approximately 0.5 in (13 mm) – This position provides improved aerody- namics by lowering the vehicle. The vehicle will automatically enter Aero Mode when the vehicle speed remains between 62 mph (99 km/h) and 66 mph (106 km/h) for greater than 20 seconds or if the vehicle speed exceeds 66 mph (106 km/h). The vehicle will return to NRH from Aero Mode if the vehicle speed remains between 30 mph (48 km/h) and 35 mph (56 km/h) for greater than 20 seconds or if the vehicle speed falls below 30 mph (48 km/h). The vehicle will enter Aero Mode, regardless of vehicle speed if the450 STARTING AND OPERATING
Selec-Terrain™ knob is turned to the “SPORT” posi- tion. Turning the Selec-Terrain™ knob to the “AUTO” position will return the system to normal operation. • Park Mode (Lowers the vehicle approximately 1.5 in (38 mm) – This position lowers the vehicle for easier passenger entry and exit as well as lowering the rear of the vehicle for easier loading and unloading of cargo. To enter Park Mode, press the “Down” button once while the vehicle speed is below 25 mph (40 km/h). Once the vehicle speed goes below 15 mph (24 km/h) the vehicle height will begin to lower. If the vehicle speed remains between 15 mph (24 km/h) and 25 mph (40 km/h) for greater than 60 seconds, or the vehicle speed exceeds 25 mph (40 km/h) the Park Mode change will be cancelled. To exit Park Mode, press the “Up” button once while in Park Mode or drive the vehicle over 15 mph (24 km/h).
The Selec-Terrain™ switch will automatically change the vehicle to the proper height based on the position of the Selec-Terrain™ switch. The height can be changed from the default Selec-Terrain™ setting by normal use of the air suspension buttons. Refer to “Selec-Terrain™” in “Starting and Operating” for further information. The system requires that the engine be running for all changes. When lowering the vehicle all of the doors, including the liftgate, must be closed. If a door is opened at any time while the vehicle is lowering the change will not be completed until the open door(s) is closed. The Quadra-Lift™ air suspension system uses a lifting and lowering pattern which keeps the headlights from incorrectly shining into oncoming traffic. When raising the vehicle, the rear of the vehicle will move up first and then the front. When lowering the vehicle, the front will move down first and then the rear.
After the engine is turned off, it may be noticed that the air suspension system operates briefly, this is normal. The system is correcting the position of the vehicle to ensure a proper appearance. To assist with changing a spare tire, the Quadra-Lift™ air suspension system has a feature which allows the auto- matic leveling to be disabled. Press and hold both the “Up” and “Down” buttons simultaneously between 5
and 10 seconds, a message will appear in the EVIC stating leveling has been disabled immediately after both buttons have been released. Refer to “Electronic Vehicle Information Center (EVIC)” in “Understanding Your Instrument Panel” for further information. Driving the vehicle over 5 mph (8 km/h) will return the air suspen- sion to normal operation. Refer to “Jacking and Tire Changing” in “What To Do In Emergencies” for further information.STARTING AND OPERATING 451
WARNING!
The air suspension system uses a high pressure volume of air to operate the system. To avoid per- sonal injury or damage to the system, see your authorized dealer for service.
Electronic Vehicle Information Center (EVIC) Display Messages When the appropriate conditions exist, a message will appear in the EVIC display. Refer to “Electronic Vehicle Information Center (EVIC)” in “Understanding Your Instrument Panel” for further information. An audible chime will be heard whenever a system error has been detected.
452 STARTING AND OPERATING Operation The indicator lamps 3 through 6 will illuminate to show the current position of the vehicle. Flashing indicator lamps will show a position which the system is working to achieve. When raising, if multiple indicator lamps are flashing on the “Up” button, the highest flashing indica- tor lamp is the position the system is working to achieve. When lowering, if multiple indicators are flashing on the ⬙Up⬙ button the lowest solid indicator lamp is the posi- tion the system is working to achieve. Pressing the “UP” button once will move the suspension one position higher from the current position, assuming all conditions are met (i.e. engine running, speed below threshold, etc). The “UP” button can be pressed multiple times, each press will raise the requested level by one position up to a maximum position of OR2 or the highest position allowed based on current conditions (i.e. vehicle speed, etc).
Pressing the “DOWN” button once will move the sus- pension one position lower from the current level, as- suming all conditions are met (i.e. engine running, doors closed, speed below threshold, etc). The “DOWN” button can be pressed multiple times. Each press will lower the requested level by one position down to a minimum of Park Mode or the lowest position allowed based on current conditions (i.e. vehicle speed, etc.) Automatic height changes will occur based on vehicle speed and the current vehicle height. The indicator lamps and EVIC messages will operate the same for automatic changes and user requested changes. • Off-Road 2 (OR2) – Indicator lamps 4, 5, and 6 will be • Off-Road 1 (OR1) – Indicator lamps 4 and 5 will be

while the vehicle is not moving provided that the engine is still running and all doors remain closed.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.
454 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 seven quarter turn fasteners and can be removed by hand.
Front Air Dam

Quadra-Lift™ – If Equipped When off-roading, it is recommended that the lowest useable vehicle height that will clear the current obstacle or terrain be selected. The vehicle height should then be raised as required by the changes in terrain. The Selec-Terrain™ switch will automatically change the vehicle to the optimized height based on the Selec- Terrain™ switch position. The vehicle height can be changed from the default height for each Selec-Terrain™ mode by normal use of the air suspension switches. Refer to “Quadra-Lift™ – If Equipped” in “Starting and Oper- ating” for further information. 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.
CAUTION!
CAUTION!
STARTING AND OPERATING 455
Do not use 4WD LOW range when operating the vehicle on dry pavement. Driveline hardware dam- age can result.
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. NOTE: Your vehicle is capable of water fording in up to 20 inches (51 cm) of water, while crossing small rivers or streams. To maintain optimal performance of your vehi- cle’s heating and ventilation system it is recommended to switch the system into recirculation mode during water fording.
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
456 STARTING AND OPERATING and/or the flow rate is reduced. If you must cross flowing water avoid depths in excess of 9 inches (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 inches (51 cm), and reduce speed appropriately to minimize wave effects. Maximum speed in 20 inches (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, 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 “Starting and Operating” for further information. 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, because engine braking may cause skidding and loss of control. 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.
STARTING AND OPERATING 457
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.458 STARTING AND OPERATING 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. • Completely inspect the underbody of your vehicle. Check tires, body structure, steering, suspension, and exhaust system for damage. • Inspect the radiator for mud and debris and clean as • 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.
required.
• 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 the radiator, fan, brake rotors, wheels, brake linings, and axle yokes inspected and cleaned as soon as possible.
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 a collision. 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
3.6L Engine Your vehicle is equipped with an electro-hydraulic power steering system that will give you good vehicle response and increased ease of maneuverability in tight spaces. The system will vary its assist to provide light efforts while parking and good feel while driving. If the electro- hydraulic power steering system experiences a fault that prevents it from providing power steering assist, then the system will provide mechanical steering capability.
STARTING AND OPERATING 459
CAUTION!
Extreme steering maneuvers may cause the electri- cally driven pump to reduce or stop power steering assistance in order to prevent damage to the system. Normal operation will resume once the system is allowed to cool.
If the “SERVICE POWER STEERING SYSTEM” message and a flashing icon are displayed on the EVIC screen, it indicates that the vehicle needs to be taken to the dealer for service. It is likely the vehicle has lost power steering assistance. Refer to “Electronic Vehicle Information Center (EVIC)” in “Understanding Your Instrument Panel” for further in- formation. If the “POWER STEERING SYSTEM OVER TEMP” mes- sage and an icon are displayed on the EVIC screen, it indicates that extreme steering maneuvers may have
460 STARTING AND OPERATING occurred, which caused an over temperature condition in the power steering system. You will lose power steering assistance momentarily until the over temperature con- dition no longer exists. Once driving conditions are safe, then pull over and let vehicle idle for a few moments until the light turns off. Refer to “Electronic Vehicle Information Center (EVIC)” in “Understanding Your Instrument Panel” for further information. NOTE: • Even if power steering assistance is no longer opera- tional, it is still possible to steer the vehicle. Under these conditions there will be a substantial increase in steering effort, especially at very low vehicle speeds and during parking maneuvers. • If the condition persists, see your authorized dealer for
service.
5.7L Engine 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. NOTE: • Increased noise levels at the end of the steering 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 steer- ing 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!
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.
Power Steering Fluid Check Checking the power steering fluid level at a defined service interval is not required. The fluid should only be
STARTING AND OPERATING 461
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.CAUTION!
Do not use chemical flushes in your power steering system as the chemicals can damage your power steering components. Such damage is not covered by the New Vehicle Limited Warranty.
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 manufacturer’s recommended power steering fluid.
462 STARTING AND OPERATING If necessary, add fluid to restore to the proper indicated level. With a clean cloth, wipe any spilled fluid from all surfaces. Refer to “Fluids, Lubricants, and Genuine Parts” in “Maintaining Your Vehicle” for further information.
