occupants and cargo should never exceed XXX kg or XXX lbs.” 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 pounds” 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 kilograms or XXX pounds.

4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if “XXX” amount equals 1400 lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lb. (since 5 x 150 = 750, and 1400 – 750 = 650 lb.) 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

STARTING AND OPERATING 285

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 calculate total load, cargo/luggage and towing capacities of your vehicle with varying seating configurations and number and size of occupants. This table is for illustra- tion purposes only and may not be accurate for the seating and load carry capacity of your vehicle. NOTE: For the following example the combined weight of occupants and cargo should never exceed 865 lbs. (392
Kg).

286 STARTING AND OPERATING

WARNING!

1. Safety—

STARTING AND OPERATING 287

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. • Under inflation increases tire flexing and can result in tire failure. • Over inflation reduces a tire’s ability to cushion shock. Objects on the road and chuck holes can cause damage that results in tire failure. • Unequal tire pressures can cause steering prob- lems. You could lose control of your vehicle. • Overinflated or under inflated tires can affect vehicle handling and can fail suddenly, resulting in loss of vehicle control. • 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 properly inflated.

288 STARTING AND OPERATING

2. 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. Under inflation also increases tire rolling resistance and results in higher fuel consump- tion. 3. Ride Comfort and Vehicle Stability— Proper tire inflation contributes to a comfortable ride. Over inflation produces a jarring and uncomfortable ride. Both under inflation and over inflation 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 either the face of the driver’s door, or the driver’s side “B” pillar.

Tire Placard Location

The pressure should be checked and adjusted as well as inspecting 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 under inflated.

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 the valve stem.

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 3 hours, or driven less than 1 mile (1 km) after a 3 hour period. The cold tire inflation pressure must not exceed the maximum inflation pres- sure molded into the tire side wall.

STARTING AND OPERATING 289

Check tire pressures more often if subject to a wide range of outdoor temperatures, as tire pressures vary with temperature changes. 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.

290 STARTING AND OPERATING

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 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 under maxi- mum load is dangerous. The added strain on your tires could cause them to fail. You could have a serious accident. Don’t 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 dealer for radial tire repairs. Tire Spinning When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle’s wheels above 35 mph (55 km/h).

WARNING!

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 someone. 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 291

These indicators are molded into the bottom of the tread grooves and will appear as bands when the tread depth becomes 1/16 inch (2 mm). When the indicators appear in 2 or more adjacent grooves, the tire should be replaced. Many states have laws requiring tire replacement at this point.

292 STARTING AND OPERATING

Life of Tire The service life of a tire is dependent upon varying factors including but not limited to: • Driving style • Tire pressure • Distance driven

WARNING!

Tires and 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 result- ing in serious injury or death.

Keep unmounted 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 (see the paragraph on tread wear indicators). Refer to the Tire and Loading Informa- tion placard for the size designation of your tire. 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, han- dling, and ride of your vehicle. We recommend that you contact your original equipment or an authorized tire dealer with any questions you may have on tire specifi- cations or capability.

WARNING!

• Do not use a tire, wheel size or rating other than that specified for your vehicle. Some combina- tions of unapproved tires and wheels may change suspension dimensions and performance charac- teristics, resulting in changes to steering, han- dling, and braking of your vehicle. This can cause unpredictable handling and stress to steering and suspension 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, other 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. • Failure to equip your vehicle with tires having adequate speed capability can result in sudden tire failure and loss of vehicle control.

STARTING AND OPERATING 293

CAUTION!

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

Alignment and Balance Poor suspension alignment may result in: • Fast tire wear. • Uneven tire wear, such as feathering and one-sided • Vehicle pull to right or left.

wear.

294 STARTING AND OPERATING

Tires may also cause the vehicle to pull left or right. Alignment will not correct this problem. See your autho- rized dealer for proper diagnosis. Improper alignment will not cause vehicle vibration. Vibration may be a result of tire and wheel out-of- balance. Proper balancing will reduce vibration and avoid tire cupping and spotty wear.

TIRE PRESSURE MONITOR SYSTEM (TPMS)

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 check the NOTE: tire pressure in all of your tires regularly and to maintain the proper pressure.

The “Tire Pressure Monitoring Telltale Light” will illuminate in the instrument cluster, and an au- dible chime will be activated when one or more tire pressures is low. The “Tire Pressure Monitoring Telltale Light” will flash on and off for 10 to 60 seconds when a system fault is detected. The flash cycle will repeat every ten minutes or until the fault condition is removed and reset. The Tire Pressure Monitor System (TPMS) consists of the following components: • Receiver Module • 5 Wheel Sensors (including Full Size Spare Tire) • Tire Pressure Monitoring Telltale Light

The system will consist of tire pressure monitoring sensors attached to each wheel through the valve stem mounting hole, a central receiver module and a “Tire Pressure Monitoring Telltale Light.” A sensor is located in the spare wheel if the vehicle is equipped with a match- ing full size spare wheel and tire assembly. NOTE: For vehicles with optional wheel/tire sizes and significantly different tire placard pressures, the placard pressure value and the low-pressure threshold value is re-programmable at your authorized dealer to accommo- date the customer selected wheel/tire combinations rec- ommended by DaimlerChrysler Corporation.

STARTING AND OPERATING 295

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 equip- ment that is not of the same size, type, and/or style. After-market wheels can cause sensor damage. Do not use tire sealant from a can, or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.

STARTING AND OPERATING 301

NOTE: The Premium Tire Pressure Monitor System will automatically locate the pressure values displayed in the correct vehicle position following a tire rotation. The suggested rotation method is the “forward-cross” shown in the following diagram.

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. 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 found in the “Maintenance Schedules” Section of this manual. More frequent rotation is permis- sible if desired. The reasons for any rapid or unusual wear should be corrected prior to rotation being per- formed.

302 STARTING AND OPERATING

FUEL REQUIREMENTS

3.7/4.7L Engines (If Equipped)

All engines (except 5.7L engines) are de- signed to meet all emissions regulations and provide excellent fuel economy and performance when using high quality un- leaded “regular” gasoline having an oc- tane rating of 87. The use of premium gasoline is not recommended. Under normal conditions, the use of premium gasoline will not provide a benefit over high quality regular gasolines, and in some circum- stances may result in poorer performance. 5.7L Engines (If Equipped)

The 5.7L engine is designed to meet all emissions regulations and provide satisfac- tory fuel economy and performance when

using high quality unleaded gasoline having an octane range of 87 to 89. The manufacturer recommends the use of 89 octane for optimum performance. The use of premium gasoline is not recommended. Under normal conditions, the use of premium gasoline will not provide a benefit over high quality regular and mid-grade gaso- lines, and in some circumstances may result in poorer performance. Light spark knock at low engine speeds is not harmful to your engine. However, continued heavy spark knock at high speeds can cause damage and immediate service is required. Poor quality gasoline can cause problems such as hard starting, stalling and hesitations. If you experience these symptoms, try another brand of gasoline before consid- ering service for the vehicle.

Over 40 auto manufacturer’s world wide have issued and endorsed consistent gasoline specifications (the World- wide Fuel Charter, WWFC) to define fuel properties necessary to deliver enhanced emissions, performance, and durability for your vehicle. The manufacturer recom- mends the use of gasoline that meets the WWFC speci- fications if they are available. Reformulated Gasoline Many areas of the country require the use of cleaner burning gasoline referred to as Reformulated Gasoline. Reformulated gasoline contains oxygenates, and is spe- cifically blended to reduce vehicle emissions and im- prove air quality. The manufacturer strongly supports the use of reformu- lated gasoline. Properly blended reformulated gasoline will provide excellent performance and durability for the engine and fuel system components.

STARTING AND OPERATING 303

Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded gasoline with oxy- genates such as 10% ethanol, MTBE, and ETBE. Oxygen- ates are required in some areas of the country during the winter months to reduce carbon monoxide emissions. Fuels blended with these oxygenates may be used in your vehicle.

CAUTION!

DO NOT use gasoline containing METHANOL. Gasoline containing methanol may damage critical fuel system components.

304 STARTING AND OPERATING

MMT In Gasoline MMT is a manganese containing metallic additive that is blended into some gasoline to increase octane. Gasoline blended with MMT provides no performance advantage beyond gasoline of the same octane number without MMT. Gasoline blended with MMT reduces spark plug life and reduces emission system performance in some vehicles. The manufacturer recommends that gasoline without MMT be used in your vehicle. The MMT content of gasoline may not be indicated on the gasoline pump, therefore, you should ask your gasoline retailer whether or not his/her gasoline contains MMT. It is even more important to look for gasoline without MMT in Canada because MMT can be used at levels higher than allowed in the United States. MMT is pro- hibited in Federal and California reformulated gasoline.

Materials Added To Fuel All gasoline sold in the United States is required to contain effective detergent additives. Use of additional detergents or other additives is not needed under normal conditions. Fuel System Cautions

CAUTION!

Follow these guidelines to maintain your vehicle’s performance: • The use of leaded gas is prohibited by Federal law. Using leaded gasoline can impair engine performance, damage the emission control system.

• An out-of-tune engine, or certain fuel or ignition malfunctions, can cause the catalytic converter to overheat. If you notice a pungent burning odor or some light smoke, your engine may be out of tune or malfunctioning and may require immediate service. Contact your dealer for service assistance. • The use of fuel additives which are now being sold as octane enhancers is not recommended. Most of these products contain high concentrations of methanol. Fuel system damage or vehicle performance problems resulting from the use of such fuels or additives is not the responsibility of the manufacturer.

NOTE: systems can result against you.

STARTING AND OPERATING 305

Carbon Monoxide Warnings

WARNING!

Carbon monoxide (CO) in exhaust gases is deadly. Follow the precautions below to prevent carbon monoxide poisoning: • Do not inhale exhaust gases. They contain carbon monoxide, a colorless and odorless gas which can kill. Never run the engine in a closed area, such as a garage, and never sit in a parked vehicle with the engine running for an extended period. If the vehicle is stopped in an open area with the engine running for more than a short period, adjust the ventilation system to force fresh, outside air into the vehicle.

306 STARTING AND OPERATING

• Guard against carbon monoxide with proper mainte- nance. Have the exhaust system inspected every time the vehicle is raised. Have any abnormal conditions repaired promptly. Until repaired, drive with all side windows fully open. • Keep the liftgate closed when driving your vehicle to prevent carbon monoxide and other poisonous ex- haust gases from entering the vehicle.

FUEL TANK FILLER CAP (GAS CAP) The fuel cap is located on the left side of the vehicle. If the fuel cap is lost or damaged, be sure the replacement cap is for use with this vehicle.

Fuel Filler Cap Location

STARTING AND OPERATING 307

CAUTION!

CAUTION!

Damage to the fuel system or emission control system could result from using an improper fuel cap (gas cap). A poorly fitting cap could let impurities into the fuel system. Also, a poorly fitting after- market cap can cause the MIL (Malfunction Indica- tor Light) to illuminate, due to fuel vapors escaping from the system. • Turn the engine off. • Rotate the fuel cap to the left to remove. • To replace the cap, insert it into the filler neck and tighten the cap about 1/4 turn until you hear one click. This is an indication that the cap is properly tightened. • Make sure that the fuel cap tether strap is not caught

under the fuel cap.

To avoid fuel spillage and overfilling, do not “top off” the fuel tank after filling.

NOTE: When the fuel nozzle “clicks” or shuts off, the fuel tank is full. Loose Fuel Filler Cap Message If the vehicle diagnostic system determines that the fuel filler cap is loose, improperly installed, or damaged, a “CHECK GAS CAP” message will be displayed in the EVIC (Electronic Vehicle Information Center). Refer to “Electronic Vehicle Information Center” in Section 4 of this manual. Tighten the fuel filler cap properly and press the odometer reset button to turn the message off. If the problem continues, the message will appear the next time the vehicle is started. Refer to “Onboard Diagnostic System — OBDII” in Section 7 of this manual for more information.

308 STARTING AND OPERATING

WARNING!

• Remove the fuel cap (gas cap) slowly to prevent fuel spray from the filler neck which may cause injury. • The volatility of some gasoline may cause a buildup of pressure in the fuel tank that may increase while you drive. This pressure can result in a spray of gasoline and/or vapors when the cap is removed from a hot vehicle. Removing the cap slowly allows the pressure to vent and prevents fuel spray. • Never have any smoking materials lit in or near the vehicle when the fuel cap is removed or the tank filled. • Never add fuel to the vehicle when the engine is

running.

WARNING!

A fire may result if gasoline is pumped into a portable container that is inside of a vehicle. You could be burned. Always place gas containers on the ground while filling.

TRAILER TOWING In this section you will find safety tips and information on limits to the type of towing you can reasonably do with your vehicle. Before towing a trailer carefully re- view this information to tow your load as efficiently and safely as possible. To maintain warranty coverage, follow the requirements and recommendations in this manual concerning ve- hicles used for trailer towing.

Common Towing Definitions The following trailer towing related definitions will assist you in understanding the following information: Gross Vehicle Weight Rating (GVWR) The GVWR is the total allowable weight of your vehicle. This includes driver, passengers, cargo and tongue weight. The total load must be limited so that you do not exceed the GVWR. Gross Trailer Weight (GTW) The gross trailer weight (GTW) is the weight of the trailer plus the weight of all cargo, consumables and equipment (permanent or temporary) loaded in or on the trailer in its ⬙loaded and ready for operation⬙ condition. The recom- mended way to measure GTW is to put your fully loaded trailer on a vehicle scale. The entire weight of the trailer must be supported by the scale.

STARTING AND OPERATING 309

Gross Combination Weight Rating (GCWR) The gross combination weight rating (GCWR) is the total permissible weight of your vehicle and trailer when weighed in combination. (Note that GCWR ratings in- clude a 150 lbs (68 kg) allowance for the presence of a driver). Gross Axle Weight Rating (GAWR) The GAWR is the maximum capacity of the front and rear axles. Distribute the load over the front and rear axles evenly. Make sure that you do not exceed either front or rear GAWR.

310 STARTING AND OPERATING

WARNING!

It is important that you do not exceed the maximum front or rear GAWR. A dangerous driving condition can result if either rating is exceeded. You could lose control of the vehicle and have an accident.

Tongue Weight (TW) The downward force exerted on the hitch ball by the trailer. In most cases it should not be less than 10% or more than 15% of the trailer load. You must consider this as part of the load on your vehicle. Frontal Area The maximum height and maximum width of the front of a trailer. Trailer Sway Control The trailer sway control is a telescoping link that can be installed between the hitch receiver and the trailer tongue

that typically provides adjustable friction associated with the telescoping motion to dampen any unwanted trailer swaying motions while traveling. Weight-Carrying Hitch A weight-carrying hitch supports the trailer tongue weight, just as if it were luggage located at a hitch ball or some other connecting point of the vehicle. These kind of hitches are the most popular on the market today and they’re commonly used to tow small- and medium-sized trailers. Weight-Distributing Hitch A weight-distributing hitch includes a receiver attached to the tow vehicle, plus a removable hitch head and spring bar assembly that fits into the receiver opening and hook up brackets that connect the spring bars to the trailer frame.

Trailer Hitch Classification The rear bumper is intended to tow trailers up to 2,000
lbs (907 kg) without added equipment or alterations to the standard equipment. Your vehicle may be factory equipped for safe towing of trailers weighing over 2,000
lbs (907 kg) with the optional Trailer Tow Prep Package. See your dealer for package content. The following chart provides the industry standard for the maximum trailer weight a given trailer hitch class can tow and should be used to assist you in selecting the correct trailer hitch for your intended towing condition.

Note 1 – The trailer tongue weight must be considered as part of the combined weight of occupants and cargo, and should never exceed the weight referenced on the Tire and Loading Information placard. Refer to the Tire– Safety Information Section in this manual. Trailer and Tongue Weight Always load a trailer with 60% to 65% of the weight in the front of the trailer. This places 10% to 15% of the Gross Trailer Weight (GTW) on the tow hitch of your vehicle. Loads balanced over the wheels or heavier in the rear can cause the trailer to sway severely side to side which will cause loss of control of vehicle and trailer. Failure to load trailers heavier in front is the cause of many trailer accidents. Never exceed the maximum tongue weight stamped on your bumper or trailer hitch.

STARTING AND OPERATING 313

Consider the following items when computing the weight on the rear axle of the vehicle: • The tongue weight of the trailer. • The weight of any other type of cargo or equipment • The weight of the driver and all passengers.

NOTE: Remember that everything put into or on the trailer adds to the load on your vehicle. Also, additional factory-installed options, or dealer-installed options, must be considered as part of the total load on your vehicle. Refer to the Tire and Loading Information plac- ard in the Tire Safety Information Section of this manual for the maximum combined weight of occupants and cargo for your vehicle. Towing Requirements To promote proper break-in of your new vehicle driv- etrain components the following guidelines are recom- mended:

CAUTION!

• Avoid towing a trailer for the first 500 miles (805
km) of vehicle operation. Doing so may damage your vehicle. • During the first 500 miles (805 km) of trailer

towing, limit your speed to 50 mph (80 km/h).

Perform the maintenance listed in Section 8 of this manual. When towing a trailer, never exceed the GAWR, or GCWR, ratings.

WARNING!

Improper towing can lead to an injury accident. Follow these guidelines to make your trailer towing as safe as possible: Make certain that the load is secured in the trailer and will not shift during travel. When trailering cargo that is not fully secured, dynamic load shifts can occur that may be difficult for the driver to control. You could lose control of your vehicle and have an accident. • When hauling cargo or towing a trailer, do not over- load your vehicle or trailer. Overloading can cause a loss of control, poor performance or damage to brakes, axle, engine, transmission, steering, suspension, chas- sis structure or tires.

STARTING AND OPERATING 315

• Safety chains must always be used between your vehicle and trailer. Always connect the chains to the frame or hook retainers of the vehicle hitch. Cross the chains under the trailer tongue and allow enough slack for turning corners. • Vehicles with trailers should not be parked on a grade. When parking, apply the parking brake on the tow vehicle. Put the tow vehicle automatic transmission in P for Park. With a manual transmission, shift the transmission into reverse. And with four-wheel-drive vehicles, make sure the transfer case is not in neutral. Always, block or ⬙chock⬙ the trailer wheels.

• GCWR must not be exceeded. • Total weight must be distributed between the tow vehicle and the trailer such that the following four ratings are not exceeded: 1. GVWR

316 STARTING AND OPERATING

2. GTW 3. GAWR 4. Tongue weight rating for the trailer hitch utilized (This requirement may limit the ability to always achieve the 10% to 15% range of tongue weight as a percentage of total trailer weight).

Towing Requirements — Tires − Do not attempt to tow a trailer while using a compact

spare tire.

− Proper tire inflation pressures are essential to the safe and satisfactory operation of your vehicle. Refer to the Tires–General Information section of this manual on Tire Pressures for proper tire inflation procedures.

− Also, check the trailer tires for proper tire inflation

pressures before trailer usage.

− Check for signs of tire wear or visible tire damage before towing a trailer. Refer to the Tires–General Information section of this manual on Tread Wear Indicators for the proper inspection procedure.

− When replacing tires refer to the Tires–General Infor- mation section of this manual on Replacement Tires for proper tire replacement procedures. Replacing tires with a higher load carrying capacity will not increase the vehicle’s GVWR and GAWR limits. Towing Requirements — Trailer Brakes − Do not interconnect the hydraulic brake system or vacuum system of your vehicle with that of the trailer. This could cause inadequate braking and possible personal injury.

− An electronically actuated trailer brake controller is required when towing a trailer with electronically actuated brakes. When towing a trailer equipped with a hydraulic surge actuated brake system, an electronic brake controller is not required.

− Trailer brakes are recommended for trailers over 1,000
lbs (454 kg) and required for trailers in excess of 2,000
lbs (907 kg).

CAUTION!

If the trailer weighs more than 1,000 lbs (454 kg) loaded, it should have its own brakes and they should be of adequate capacity. Failure to do this could lead to accelerated brake lining wear, higher brake pedal effort, and longer stopping distances.

STARTING AND OPERATING 317

WARNING!

Do not connect trailer brakes to your vehicle’s hy- draulic brake lines. It can overload your brake sys- tem and cause it to fail. You might not have brakes when you need them and could have an accident. Towing any trailer will increase your stopping dis- tance. When towing you should allow for additional space between your vehicle and the vehicle in front of you. Failure to do so could result in an accident.

Towing Requirements — Trailer Lights & Wiring Whenever you pull a trailer, regardless of the trailer size, stop lights and turn signals on the trailer are required for motoring safety. The Trailer Tow Package may include a 4 and 7 pin wiring harness. Use a factory approved trailer harness and connector.

318 STARTING AND OPERATING

NOTE: Do not cut or splice wiring into the vehicles wiring harness. The electrical connections are all complete to the vehicle but you must mate the harness to a trailer connector. Refer to the following illustrations.

7- Pin Connector

Towing Tips Before setting out on a trip, practice turning, stopping and backing the trailer in an area away from heavy traffic.

4 - Pin Connector

If using a manual transmission vehicle for trailer towing, all starts must be in FIRST gear to avoid excessive clutch slippage. Towing Tips — Automatic Transmission The “D” range can be selected when towing. However, if frequent shifting occurs while in this range, the ”Tow/ Haul” mode (if equipped) or the “3” range should be selected. Shift the transmission to Drive position 2 on more severe grades. NOTE: Using the ”Tow/Haul” mode (if equipped) or the “3” range while operating the vehicle under heavy operating conditions will improve performance and ex- tend transmission life by reducing excessive shifting and heat build up. This action will also provide better engine braking.

STARTING AND OPERATING 319

The automatic transmission fluid and filter should be changed if you REGULARLY tow a trailer for more than 45 minutes of continuous operation. See Schedule “B” in section 8 of this manual for transmission fluid change intervals. NOTE: Check the automatic transmission fluid level before towing. Towing Tips — Electronic Speed Control (If Equipped) − Don’t use in hilly terrain or with heavy loads. − When using the speed control, if you experience speed drops greater than 10 mph (16 km/h), disengage until you can get back to cruising speed.

− Use speed control in flat terrain and with light loads to

maximize fuel efficiency.

320 STARTING AND OPERATING

Towing Tips — Cooling System To reduce potential for engine and transmission over- heating, take the following actions: − City Driving When stopped for short periods of time, put transmission in neutral and increase engine idle speed. − Highway Driving Reduce speed. − Air Conditioning Turn off temporarily. − refer to Cooling System Operating information in the Maintenance section of this manual for more informa- tion.

RECREATIONAL TOWING (BEHIND MOTORHOME, ETC.)

Towing – 2WD Models

Recreational towing is allowed ONLY if the driveshaft is removed. Towing with the rear wheels on the ground while the driveshaft is connected can result in severe transmission damage. Towing — Quadra-Trac I (Single-Speed Transfer Case) 4WD Models

Recreational towing is not allowed. This model does not have a N (Neutral) position in the transfer case.

Towing — Quadra–Trac II /Quadra–Drive II 4WD Models

CAUTION!

Front or rear wheel lifts should not be used. Internal damage to the transmission or transfer case will occur if a front or rear wheel lift is used when recreational towing.

NOTE: The transfer case must be in the N (Neutral) position, and the transmission must be in the P (Park) position for recreational towing. Shifting Into Neutral (N) Use the following procedure to prepare your vehicle for recreational towing.

STARTING AND OPERATING 321

NOTE: When shifting out of transfer case N (Neutral), turning the engine OFF may be required to avoid gear clash.

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.

STARTING AND OPERATING 325

CAUTION!

Do not use a bumper mounted clamp-on tow bar on your vehicle. The bumper face bar will be damaged.

SNOW PLOW Snow plows, winches, and other aftermarket equipment should not be added to the front end of your vehicle. The airbag crash sensors may be affected by the change in the front end structure. The airbags could deploy unexpect- edly or could fail to deploy during a collision.

WARNING!

Do not add a snow plow, winches, or any other aftermarket equipment to the front of your vehicle. This could adversely affect the functioning of the airbag system and you could be injured.

328 WHAT TO DO IN EMERGENCIES

HAZARD WARNING FLASHERS Your vehicle’s hazard warning flasher is an emergency warning system. When you activate it, all front and rear directional signals will flash intermittently. Use it when your vehicle is disabled on or near the road. It warns other drivers to steer clear of you and your vehicle. This is an emergency warning system, not to be used when the vehicle is in motion.

Hazard Warning Switch

To activate the warning flasher, push down on the button on top of the steering column until it latches. To turn the warning flasher off, push down again to unlatch the button. NOTE: With extended use, the flasher may run down your battery.

IF YOUR ENGINE OVERHEATS In any of the following situations, you can reduce the potential for overheating by taking the appropriate ac- tion. • On the highways — Slow down. • In city traffic — While stopped, put transmission in N

(Neutral), but do not increase engine idle speed.

NOTE: There are steps that you can take to slow down an impending overheat condition. If your air conditioner is on, turn it off. The air conditioning system adds heat to the engine cooling system and turning off the A/C removes this heat. You can also turn the Temperature Control to maximum heat, the Mode Control to floor, and the Fan Control to High. This allows the heater core to act as a supplement to the radiator and aids in removing heat from the engine cooling system.

WHAT TO DO IN EMERGENCIES 329

CAUTION!

Driving with a hot cooling system could damage your vehicle. If the temperature gauge reads “H”, pull over and stop the vehicle. Idle the vehicle with the air conditioner turned off until the pointer drops back into the normal range. If the pointer remains on the “H”, and you hear continuous chimes, turn the engine off immediately, and call for service.

330 WHAT TO DO IN EMERGENCIES

JACKING AND TIRE CHANGING

WARNING!

• Getting under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never get any part of your body under a vehicle that is on a jack. If you need to get under a raised vehicle, take it to a service center where it can be raised on a lift. • The jack is designed to use as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes. The vehicle should be jacked on a firm level surface only. Avoid ice or slippery areas.

Jack Location The scissor-type jack and tire changing tools are located in the passenger side compartment behind the second row seat.

Jack Storage Location

Spare Tire Stowage The spare tire is stowed under the rear of the vehicle by means of a cable winch mechanism. To remove or stow the spare, use the jack handle to rotate the “spare tire drive” nut. The nut is located under a plastic cover at the center-rear of the cargo floor area, just inside the liftgate opening.

WARNING!

Do not use power tools to winch the tire up or down. Impact type tools can damage the winch mechanism.

WHAT TO DO IN EMERGENCIES 331

Lowering/Raising Spare Tire

332 WHAT TO DO IN EMERGENCIES

Spare Tire Removal Fit the jack handle extension over the drive nut. Use the Lug Wrench to rotate the nut counter clockwise until the spare is on the ground with enough slack in the cable to allow to pull the tire out from under the vehicle.

CAUTION!

The winch mechanism is designed for use with the jack extension tube only. Use of an air wrench or other power tools is not recommended and can damage the winch.

When the spare is clear, tilt the retainer at the end of the cable and pull it through the center of the wheel.

Preparations For Jacking Park the vehicle on a firm level surface, avoid ice or slippery areas, set the parking brake and place the gear selector in P (Park). Turn OFF the ignition.

WARNING!

Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to avoid being hit when operating the jack or changing the wheel. • Turn on the Hazard Warning Flasher.

• Block both the front and rear of the wheel diagonally oppo- site of the jacking position.

For example, if changing the right front tire, block the left rear wheel. • Passengers should not remain in the vehicle when the

vehicle is being jacked.

Jacking Instructions

1. Remove the spare tire, jack, and tools from storage. 2. Loosen (but do not remove) the wheel lug nuts by turning them to the left one turn while the wheel is still on the ground.

WHAT TO DO IN EMERGENCIES 333

3. Assemble the jack and jacking tools as shown. Connect jack handle driver (A) to two extensions (B), then to the lug wrench (C).

334 WHAT TO DO IN EMERGENCIES

4. Locate the jack as shown. For the front axle, place it under the front lower control arm as shown. For the rear axle, place it under the axle near the wheel to be changed. Ensure the jack is closest to the inside of the wheel when jacking on the rear axle. Do not raise the vehicle until you are sure the jack is fully engaged.

Rear Jacking Location

5. Raise the vehicle by turning the jack screw clockwise. Raise the vehicle only until the tire just clears the surface and enough clearance is obtained to install the spare tire. Minimum tire lift provides maximum stability.

Front Jacking Location

WARNING!

Raising the vehicle higher than necessary can make the vehicle less stable. It could slip off the jack and hurt someone near it. Raise the vehicle only enough to remove the tire.

6. Remove the lug nuts and wheel. 7. Position the spare wheel/tire on the vehicle and install the lug nuts with the cone-shaped end toward the wheel. Lightly tighten the nuts. To avoid the risk of forcing the vehicle off the jack, do not tighten the nuts fully until the vehicle has been lowered. 8. Lower the vehicle by turning the jack screw counter clockwise, and remove the jack and wheel blocks.

WHAT TO DO IN EMERGENCIES 335

9. Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alternate nuts until each nut has been tightened twice. Correct wheel nut tightness is 130 N·m (95 ft. lbs). If in doubt about the correct tightness, have them checked with a torque wrench by your authorized dealer or at a service station. 10. Lower the jack to it’s fully closed position.

WARNING!

A loose tire or jack, thrown forward in a collision or hard stop could endanger the occupants of the ve- hicle. Always stow the jack parts and the spare tire in the places provided.

11. Secure the tire, jack, and tools in their proper loca- tions.

336 WHAT TO DO IN EMERGENCIES

NOTE: Tire should be stowed with the “beauty” side up. Storing the tire upside down may result in scratching or damage to the wheel face. Continue winching up the tire until you hear the winch “ratchet” three times. Double check to ensure the tire is snug against the underbody of the vehicle. Damage to the winch cable may result if the vehicle is driven with the tire loose.

WARNING!

Do not use power tools to winch the tire up or down. Impact type tools may damage the winch mecha- nism.

12. Reinstall the plastic plug into the floor of the cargo area.

JUMP STARTING PROCEDURE

NOTE: Check the charge indicator on the battery. If the indicator is light or yellow, replace the battery. 1. Wear eye protection and remove any metal jewelry such as watch bands or bracelets that might make an unintended electrical contact. 2. When boost is provided by a battery in another vehicle, park that vehicle within booster cable reach but without letting the vehicles touch. Set the parking brake, place the transmission in P (Park), and turn the ignition to OFF for both vehicles. 3. Turn off the heater, radio and all unnecessary electrical loads. 4. Connect one end of a jumper cable to the positive terminal of the discharged battery. Connect the other end of the same cable to the positive terminal of the booster battery.

5. Connect the other cable, first to the negative terminal of the booster battery and then connect the other end to a non-paint metal surface on the engine of the vehicle with the discharged battery. Make sure you have a good contact on the engine. 6. Start the engine in the vehicle which has the booster battery, let the engine idle a few minutes, then start the engine in the vehicle with the discharged battery. 7. When removing the jumper cables, reverse the above sequence exactly. Be careful of the moving belts and fan. NOTE: To start the vehicle following connection of a booster battery, the Security Alarm System must first be disabled by cycling a front door key cylinder or by using the keyless entry transmitter.

WHAT TO DO IN EMERGENCIES 337

WARNING!

Jump starting can be dangerous. To avoid personal injury or damage to electrical components in vehicle, observe the following warnings: • Battery fluid is a corrosive acid solution and can burn or even blind you. Don’t allow battery fluid to contact your eyes, skin, or clothing. Don’t lean over a battery when attaching clamps. If acid splashes in eyes or on skin, flush the area immediately with large amounts of water. • Do not use a booster battery or any other booster source that has a greater than 12–volt system, i.e., do not use a 24–volt power source. • Never attempt to jump start a discharged battery that is frozen, because it could rupture or explode during jump starting.

338 WHAT TO DO IN EMERGENCIES

• Be sure your vehicle is not touching the jump start • Observe all Battery Warnings in Section 7 of this

vehicle.

manual, while jump starting your vehicle.

WARNING!

Do not attempt to push or tow your vehicle to get it started. Unburned fuel could enter the catalytic converter and, once the engine has started, ignite and damage the converter and vehicle.

EMERGENCY TOW HOOKS — IF EQUIPPED If your vehicle is equipped with tow hooks, there will be one in the rear and two mounted on the front of the vehicle. The rear hook will be located on the driver’s side of the vehicle. NOTE: For off-road recovery, it is recommended to use both of the front tow hooks to minimize the risk of damage to the vehicle.

CAUTION!

Tow hooks are for emergency use only, to rescue a vehicle stranded off road. Do not use tow hooks for tow truck hookup or highway towing. You could damage your vehicle.

ONBOARD DIAGNOSTIC SYSTEM — OBD II Your vehicle is equipped with a sophisticated onboard diagnostic system called OBD II. This system monitors the performance of the emissions, engine, and automatic transmission control systems. When these systems are operating properly, your vehicle will provide excellent performance and fuel economy, as well as engine emis- sions well within current government regulations. If any of these systems require service, the OBD II system will turn on the “Malfunction Indicator Light.” It will also store diagnostic codes and other information to assist your service technician in making repairs. Al- though your vehicle will usually be drivable and not need towing, see your dealer for service as soon as possible.

MAINTAINING YOUR VEHICLE 347

CAUTION!

• Prolonged driving with the “Malfunction Indica- tor Light” on could cause further damage to the emission control system. It could also affect fuel economy and driveability. The vehicle must be serviced before any emissions tests can be per- formed. • If the “Malfunction Indicator Light” is flashing while the engine is running, severe catalytic con- verter damage and power loss will soon occur. Immediate service is required.

Loose Fuel Filler Cap Message After fuel is added, the vehicle diagnostic system can determine if the fuel filler cap is loose, improperly installed, or damaged. A loose fuel filler cap message will be displayed in the instrument cluster. Tighten the gas

348 MAINTAINING YOUR VEHICLE

cap until a ⬙clicking⬙ sound is heard. This is an indication that the gas cap is properly tightened. Press the odometer reset button to turn the message off. If the problem persists, the message will appear the next time the vehicle is started. This might indicate a damaged cap. If the problem is detected twice in a row, the system will turn on the Malfunction Indicator Light (MIL). Resolving the problem will turn the MIL light off.

EMISSIONS INSPECTION AND MAINTENANCE PROGRAMS In some localities, it may be a legal requirement to pass an inspection of your vehicle’s emissions control system. Failure to pass could prevent vehicle registration.

For states which have an I/M (Inspection and Maintenance) requirement, this check verifies the following: the MIL (Malfunction Indicator Lamp)

is functioning and is not on when the engine is running, and that the OBD (On Board Diagnostic) system is ready for testing. Normally, the OBD system will be ready. The OBD system may not be ready if your vehicle was recently serviced, if you recently had a dead battery, or a battery replacement. If the OBD system should be determined not ready for the I/M test, your vehicle may fail the test. Your vehicle has a simple ignition key actuated test which you can use prior to going to the test station. To check if your vehicle’s OBD system is ready, you must do the following: 1. Insert your ignition key into the ignition switch. 2. Turn the ignition to the ON position, but do not crank or start the engine. 3. If you crank or start the engine, you will have to start this test over.

4. As soon as you turn your key to the ON position, you will see your MIL symbol come on as part of a normal bulb check. 5. Approximately 15 seconds later, one of two things will happen:

a. The MIL will flash for about 10 seconds and then return to being fully illuminated until you turn off the ignition key or start the engine. This means that your vehicle’s OBD system is not ready and you should not proceed to the I/M station. b. The MIL will not flash at all and will remain fully illuminated until you turn off the ignition key or start the engine. This means that your vehicle’s OBD system is ready and you can proceed to the I/M station.

If your OBD system is not ready, you should see your authorized dealer or repair facility. If your vehicle was recently serviced or had a battery failure or replacement,

MAINTAINING YOUR VEHICLE 349

you may need to do nothing more than drive your vehicle as you normally would in order for your OBD system to update. A recheck with the above test routine may then indicate that the system is now ready. Regardless of whether your vehicle’s OBD system is ready or not ready, if the MIL symbol is illuminated during normal vehicle operation, you should have your vehicle serviced before going to the I/M station. The I/M station can fail your vehicle because the MIL symbol is on with the engine running.

REPLACEMENT PARTS Use of genuine Mopar威 parts for normal/scheduled maintenance and repairs is highly recommended to in- sure the designed performance. Damage or failures caused by the use of non-Mopar威 parts for maintenance and repairs will not be covered by the manufacturer’s warranty.

WARNING!

You can be badly injured working on or around a motor vehicle. Do only that service work for which you have the knowledge and the proper equipment. If you have any doubt about your ability to perform a service job, take your vehicle to a competent mechanic.

MAINTENANCE PROCEDURES The pages that follow contain the required maintenance services determined by the engineers who designed your vehicle. Besides the maintenance items for which there are fixed maintenance intervals, there are other items that should operate satisfactorily without periodic maintenance. However, if a malfunction of these items does occur, it

could adversely affect the engine or vehicle performance. These items should be inspected if a malfunction is observed or suspected. Engine Oil

Checking Oil Level To assure proper engine lubrication, the engine oil must be maintained at the correct level. Check the oil level at regular intervals, such as every fuel stop. The best time to check the engine oil level is about 5
minutes after a fully warmed engine is shut off or before starting the engine after it has sat overnight. Checking the oil while the vehicle is on level ground will improve the accuracy of the oil level readings. Maintain the oil level in the SAFE level range. Adding 1 U.S. Quart (0.95L) of oil when the level is at the bottom of the SAFE range will result in the level being at the top of the SAFE range.

MAINTAINING YOUR VEHICLE 351

CAUTION!

Overfilling or underfilling the crankcase will cause aeration or loss of oil pressure. This could damage your engine.

Change Engine Oil Road conditions as well as your kind of driving affect the interval at which your oil should be changed. Check the following to determine if any apply to you: • Day or night temperatures are below 32°F (0°C) • Stop and go driving • Extensive engine idling • Driving in dusty conditions • Short trips of less than 10 miles (16.2 km)

352 MAINTAINING YOUR VEHICLE

speeds during hot weather, above 90°F (32°C)

• More than 50% of your driving is at sustained high • Trailer towing • Taxi, Police, or delivery service (Commercial Service) • Off road or desert operation • If equipped for and operating with E-85 (ethanol) fuel If ANY of these apply to you, then change your engine oil every 3,000 miles (5 000 km) or 3 months, whichever comes first, and follow the maintenance recommenda- tions in “Maintenance Schedule B.” If none of these apply to you, then change your engine oil every 6,000 miles (10 000 km) or 6 months, whichever comes first. NOTE: Under no circumstances should oil change in- tervals exceed 6,000 miles (10 000 km) or 6 months whichever comes first.

Engine Oil Selection For best performance and maximum protection for all engines under all types of operating conditions, the manufacturer recommends engine oils that are API Cer- tified and meet the requirements of DaimlerChrysler Material Standard MS-6395. Use Mopar威 or an equiva- lent oil meeting the specification MS-6395.

Oil Filler Caps

American Petroleum Institute (API) Engine Oil Identification Symbol

This symbol means that the oil has been certified by the American Petroleum Institute (API). The manufacturer only recommends API Certified engine oils that meet of DaimlerChrysler Material Stan- dard MS-6395. Use Mopar威 or an equivalent oil meeting the specifi-

requirements

the

cation MS-6395. Engine Oil Viscosity (3.7L and 4.7L Engines) SAE 5W-30 engine oil is recommended for all operating temperatures. This engine oil improves low tempera- ture starting and vehicle fuel economy. Your engine oil filler cap also shows the recommended engine oil viscosity for your vehicle.

MAINTAINING YOUR VEHICLE 353

Engine Oil Viscosity (5.7L Engines) SAE 5W-20 engine oil is recommended for all operating temperatures. This engine oil improves low tempera- ture starting and vehicle fuel economy. Your engine oil filler cap also shows the recommended engine oil viscosity for your vehicle. For information on engine oil filler cap location, see the Engine Compartment illustration in this section. Lubricants which do not have both, the engine oil certi- fication mark and the correct SAE viscosity grade num- ber should not be used. NOTE: Vehicles equipped with 5.7L engines must use 5W–20 oil. Failure to do so may result in improper operation of the Multiple Displacement System (MDS). Refer to “Multi Displacement System” in Section 5 of this manual.

354 MAINTAINING YOUR VEHICLE

Materials Added to Engine Oils The manufacturer strongly recommends against the ad- dition of any additives (other than leak detection dyes) to engine oil. Engine oil is an engineered product and it’s performance may be impaired by supplemental addi- tives. Disposing of Used Engine Oil Care should be taken in disposing of the used engine oil from your vehicle. Used oil, indiscriminately discarded, can present a problem to the environment. Contact your local authorized dealer, service station, or governmental agency for advice on how and where used oil can be safely discarded in your area. Engine Oil Filter The engine oil filter should be replaced with a new filter at every oil change.

Engine Oil Filter Selection All of the manufacturer’s engines have a full-flow type disposable oil filter. Use a filter of this type for replace- ment. The quality of replacement filters varies consider- ably. Only high quality filters should be used to assure most efficient service. Mopar威 engine oil filters are high quality oil filters and are recommended. Drive Belts — Check Condition and Tensioner Belt tension is controlled by means of an automatic tensioner. No belt tension adjustments are required. However, belt and belt tensioner condition should be inspected at the specified intervals, and replaced if re- quired. See your authorized dealer for service. At the mileage indicated in the maintenance schedule, all belts and tensioner should be checked for condition. Improper belt tension can cause belt slippage and failure.

Belts should be inspected for evidence of cuts, cracks, glazing, or frayed cords and replaced if there is indication of damage which could result in belt failure. Low gen- erator belt tension can cause battery failure. Also, check belt routing to make sure there is no inter- ference between the belts and other engine components. Spark Plugs Spark plugs must fire properly to assure engine perfor- mance and emission control. New spark plugs should be installed at the specified mileage. The entire set should be replaced if there is any malfunction due to a faulty spark plug. Refer to the “Vehicle Emission Control Informa- tion” label in the engine compartment for spark plug information.

MAINTAINING YOUR VEHICLE 355

Catalytic Converter The catalytic converter requires the use of unleaded fuel only. Leaded gasoline will destroy the effectiveness of the converter as an emission control device. Under normal operating conditions, the catalytic con- verter will not require maintenance. However, it is im- portant to keep the engine properly tuned to assure proper catalyst operation and prevent possible catalyst damage.

356 MAINTAINING YOUR VEHICLE

CAUTION!

WARNING!

Damage to the catalytic converter can result if your vehicle is not kept in proper operating condition. In the event of engine malfunction, particularly involv- ing engine misfire or other apparent loss of perfor- mance, have your vehicle serviced promptly. Contin- ued operation of your vehicle with a severe malfunction could cause the converter to overheat, resulting in possible damage to the converter and vehicle.

A hot exhaust system can start a fire if you park over materials that can burn. Such materials might be grass or leaves coming into contact with your ex- haust system. Do not park or operate your vehicle in areas where your exhaust system can contact any- thing that can burn.

In unusual situations involving grossly malfunctioning engine operation, a scorching odor may suggest severe and abnormal catalyst overheating. If this occurs, stop the vehicle, turn off the engine and allow it to cool. Service, including a tune up to manufacturer’s specifica- tions, should be obtained immediately.

To minimize the possibility of catalytic converter dam- age: • Do not shut off the engine or interrupt the ignition when the transmission is in gear and the vehicle is in motion. • Do not try to start the engine by pushing or towing the • Do not idle the engine with any spark plug wires disconnected or removed, such as when diagnostic testing. • Do not idle the engine for prolonged periods during very rough idle or malfunctioning operating condi- tions.

Intentional tampering with emissions control in civil penalties being assessed

NOTE: systems can result against you. Crankcase Emission Control System Proper operation of this system depends on freedom from sticking or plugging due to deposits. As vehicle mileage builds up, the PCV valve and passages may accumulate deposits. If a valve is not working properly, replace it with a new valve. DO NOT ATTEMPT TO CLEAN THE OLD PCV VALVE! Check ventilation hose for indication of damage or plugging deposits. Replace if necessary.

358 MAINTAINING YOUR VEHICLE

Air Cleaner Filter Under normal driving conditions, replace the air filter at the intervals shown on “Maintenance Schedule A.” If, however, you drive the vehicle frequently under dusty or severe conditions, the filter element should be inspected periodically and replaced if necessary at the intervals shown on “Maintenance Schedule B.”

WARNING!

The air cleaner can provide protection in the case of engine backfire. Do not remove the air cleaner unless it is necessary for repair or maintenance. Make sure that no one is near the engine compart- ment before starting the vehicle with the air cleaner removed. Failure to do so can result in serious personal injury.

Maintenance-Free Battery Your vehicle is equipped with a maintenance-free battery. You will never have to add water, nor is periodic main- tenance required.

WARNING!

Battery posts, terminals, and related accessories con- tain lead and lead compounds. Always wash hands after handling the battery.

MAINTAINING YOUR VEHICLE 359

CAUTION!

It is essential when replacing the cables on the battery that the positive cable is attached to the positive post and the negative cable is attached to the negative post. Battery posts are marked (+) positive and negative (-) and identified on the battery case. Also, if a “fast charger” is used while battery is in the vehicle, disconnect both vehicle battery cables be- fore connecting the charger to battery. Do not use a “fast charger” to provide starting voltage.

Air Conditioner Maintenance For best possible performance, your air conditioner should be checked and serviced by an Authorized Dealer at the start of each warm season. This service should include cleaning of the condenser fins and a performance test. Drive belt condition should also be checked at this time.

To determine the battery charge, check the battery test indicator (if equipped) on top of the battery. Refer to the illustration.

360 MAINTAINING YOUR VEHICLE

WARNING!

• Use only refrigerants and compressor lubricants approved by the manufacturer for your air condi- tioning system. Some unapproved refrigerants are flammable and can explode, injuring you. Other unapproved refrigerants or lubricants can cause the system to fail, requiring costly repairs. Refer to Section 3 of the Warranty Information Book for additional warranty information. • The air conditioning system contains refrigerant under high pressure. To avoid risk of personal injury or damage to the system, adding refrigerant or any repair requiring lines to be disconnected should be done by an experienced repairman.

Refrigerant Recovery and Recycling R-134a Air Conditioning Refrigerant is a hydrofluorocar- bon (HFC) that is endorsed by the Environmental Pro- tection Agency and is an ozone-saving product. How- ever, the manufacturer recommends that air conditioning service be performed by dealers or other service facilities using recovery and recycling equipment.
