366 MAINTAINING YOUR VEHICLE gas cap until a ⬙clicking⬙ sound is heard. This is an indication that the gas cap is properly tightened. The message will remain displayed until the vehicle diagnostic system can retest the fuel system. The test will perform the next time the vehicle is started, if the vehicle was keyed off above 40°F (4°C) outside temperature and the following vehicle start is above 40°F (4°C) outside temperature. It may be possible to have a message that will not clear due to the test being disabled due to low outside temperatures. If the test is performed and the problem is gone, the message will disappear. 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 MIL. Resolving the problem will turn the MIL off. See your authorized dealer for service.

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 that require an Inspection and Mainte- nance (I/M), this check verifies the “Malfunction Indicator Light (MIL)” is functioning and is not on when the engine is running, and that the OBD II system is ready for testing. Normally, the OBD II system will be ready. The OBD II system may not be ready if your vehicle was recently serviced, recently had a dead battery or a battery replace- ment. If the OBD II 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 II system is ready, you must do the following: 1. Turn the ignition switch to the ON position, but do not crank or start the engine. 2. If you crank or start the engine, you will have to start this test over. 3. As soon as you turn the ignition switch to the ON position, you will see the MIL symbol come on as part of a normal bulb check. 4. 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 or start the engine. This means that your vehicle’s OBD II system is not ready and you should not proceed to the I/M station.

MAINTAINING YOUR VEHICLE 367
b. The MIL will not flash at all and will remain fully illuminated until you turn OFF the ignition or start the engine. This means that your vehicle’s OBD II system is ready and you can proceed to the I/M station.

If your OBD II 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, you may need to do nothing more than drive your vehicle as you normally would in order for your OBD II 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 II system is ready or not, if the MIL 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 is on with the engine running.

368 MAINTAINING YOUR VEHICLE REPLACEMENT PARTS Use of genuine MOPAR威 parts for normal/scheduled maintenance and repairs is highly recommended to en- 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.

DEALER SERVICE Your authorized dealer has the qualified service person- nel, special tools, and equipment to perform all service operations in an expert manner. Service Manuals are available which include detailed service information for your vehicle. Refer to these manuals before attempting any procedure yourself. Intentional tampering with emissions control NOTE: systems may void your warranty and could result in civil penalties being assessed against you.

WARNING!

You can be badly injured working on or around a motor vehicle. Only do 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 me- chanic.

MAINTENANCE PROCEDURES The pages that follow contain the required maintenance services determined by the engineers who designed your vehicle. Besides those maintenance items specified in the fixed maintenance schedule, there are other components which may require servicing or replacement in the future.

CAUTION!

• Failure to properly maintain your vehicle or per- form repairs and service when necessary could result in more costly repairs, damage to other components or negatively impact vehicle perfor- mance. Immediately have potential malfunctions examined by an authorized Chrysler Group LLC dealership or qualified repair center. • Your vehicle has been built with improved fluids that protect the performance and durability of your vehicle and also allow extended maintenance intervals. Do not use chemical flushes in these components as the chemicals can damage your engine, transmission, power steering or air condi- tioning. Such damage is not covered by the New Vehicle Limited Warranty. If a flush is needed because of component malfunction, use only the specified fluid for the flushing procedure.

MAINTAINING YOUR VEHICLE 369

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 five 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.

370 MAINTAINING YOUR VEHICLE

CAUTION!

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

Change Engine Oil The oil change indicator system will remind you that it is time to take your vehicle in for scheduled maintenance. Refer to “Maintenance Schedule” for further information. NOTE: Under no circumstances should oil change intervals exceed 6,000 miles (10 000 km) or six months, whichever occurs first.

Engine Oil Selection — Gasoline Engines 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 Chrysler Material Standard MS-6395. 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.

CAUTION!

Do not use chemical flushes in your engine oil as the chemicals can damage your engine. Such damage is not covered by the New Vehicle Limited Warranty.

Engine Oil Viscosity (3.7L and 5.7L Engines) SAE 5W-20 engine oil is recommended for all operating temperatures. This engine oil improves low temperature starting and vehicle fuel economy. The engine oil filler cap also shows the recommended engine oil viscosity for your vehicle. For information on engine oil filler cap location, refer to “Engine Compart- ment” in “Maintaining Your Vehicle” for further informa- tion. NOTE: Vehicles equipped with a 5.7L engine must use SAE 5W-20 oil. Failure to do so may result in improper operation of the Multiple Displacement System (MDS). Refer to “Multi-Displacement System” in “Starting and Operating” for further information. Lubricants, which do not have both the engine oil certi- fication mark and the correct SAE viscosity grade num- ber, should not be used.

MAINTAINING YOUR VEHICLE 371

Synthetic Engine Oils You may use synthetic engine oils if the recommended oil quality requirements are met, and the recommended main- tenance intervals for oil and filter changes are followed. Materials Added to Engine Oils The manufacturer strongly recommends against the ad- dition of any additives (other than leak detection dyes) to the engine oil. Engine oil is an engineered product and its performance may be impaired by supplemental additives. Disposing of Used Engine Oil and Oil Filters Care should be taken in disposing of used engine oil and oil filters from your vehicle. Used oil and oil filters, indiscriminately discarded, can present a problem to the environment. Contact your local authorized dealer, ser- vice station, or governmental agency for advice on how and where used oil and oil filters can be safely discarded in your area.

372 MAINTAINING YOUR VEHICLE Engine Oil Filter The engine oil filter should be replaced with a new filter at every oil change. Engine Oil Filter Selection The manufacturer’s engines have a full-flow type dispos- able oil filter. Use a filter of this type for replacement. The quality of replacement filters varies considerably. Only high-quality filters should be used to assure most effi- cient service. MOPAR威 engine oil filters are high-quality oil filters and are recommended.

Engine Air Cleaner Filter Refer to “Maintenance Schedule” for further information.

WARNING!

The air induction system (air cleaner, hoses, etc) can provide a measure of protection in the case of engine backfire. Do not remove the air induction system (air cleaner, hoses, etc.) unless such removal is necessary for repair or maintenance. Make sure that no one is near the engine compartment before starting the vehicle with the air induction system (air cleaner, hoses, etc.) removed. Failure to do so can result in serious personal injury.

Engine Air Cleaner Filter Selection The quality of replacement engine air cleaner filters varies considerably. Only high quality filters should be used to assure most efficient service. MOPAR威 engine air cleaner filters are a high quality filter and are recommended. 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.

MAINTAINING YOUR VEHICLE 373

WARNING!

• Battery fluid is a corrosive acid solution and can burn or even blind you. Do not allow battery fluid to contact your eyes, skin or clothing. Do not lean over a battery when attaching clamps. If acid splashes in eyes or on skin, flush the area imme- diately with large amounts of water. • Battery gas is flammable and explosive. Keep flame or sparks away from the battery. Do not use a booster battery or any other booster source with an output greater than 12 Volts. Do not allow cable clamps to touch each other. • Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling.

374 MAINTAINING YOUR VEHICLE

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. • If a “fast charger” is used while battery is in the vehicle, disconnect both vehicle battery cables before connecting the charger to the 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.

CAUTION!

Do not use chemical flushes in your air conditioning system as the chemicals can damage your air condi- tioning components. Such damage is not covered by the New Vehicle Limited Warranty.

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 Warranty Information Book, located on the DVD, for further 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.

NOTE: Use only manufacturer approved A/C System Sealers, Stop Leak Products, Seal Conditioners, Compres- sor Oil, and Refrigerants.

MAINTAINING YOUR VEHICLE 375

Refrigerant Recovery and Recycling R-134a Air Conditioning Refrigerant is a hydrofluoro- carbon (HFC) that is endorsed by the Environmental Protection Agency (EPA) and is an ozone-saving product. However, the manufacturer recommends that air condi- tioning service be performed by authorized dealers or other service facilities using recovery and recycling equipment. Body Lubrication Locks and all body pivot points, including such items as seat tracks, door hinge pivot points and rollers, liftgate, tailgate, sliding doors and hood hinges, should be lubri- cated periodically with a lithium based grease, such as MOPAR威 Spray White Lube or equivalent to assure quiet, easy operation and to protect against rust and wear. Prior to the application of any lubricant, the parts concerned should be wiped clean to remove dust and grit; after lubricating excess oil and grease should be removed. Particular attention should also be given to

376 MAINTAINING YOUR VEHICLE hood latching components to ensure proper function. When performing other underhood services, the hood latch, release mechanism and safety catch should be cleaned and lubricated. The external lock cylinders should be lubricated twice a year, preferably in the Fall and Spring. Apply a small amount of a high quality lubricant, such as MOPAR威 Lock Cylinder Lubricant or equivalent directly into the lock cylinder. Windshield Wiper Blades Clean the rubber edges of the wiper blades and the windshield periodically with a sponge or soft cloth and a mild nonabrasive cleaner to remove accumulations of salt or road film. Operation of the wipers on dry glass for long periods may cause deterioration of the wiper blades. Always use washer fluid when using the wipers to remove salt or dirt from a dry windshield.

Avoid using the wiper blades to wipe frost or ice from the windshield. Keep the blade rubber out of contact with petroleum products such as engine oil, gasoline, etc. NOTE: Life expectancy of wiper blades varies depend- ing on geographical area and frequency of use. Poor performance of blades may be present with chattering, marks, water lines or wet spots. If any condition is present please proceed to clean wiper blades with humid cloth removing any debris that may be affecting its function. Adding Washer Fluid On vehicles equipped with a Electronic Vehicle Informa- tion Center (EVIC), the low washer fluid level will be indicated. When the sensor detects a low fluid level, the windshield will light on the vehicle graphic outline and the “WASHER FLUID LOW” message will be displayed. The fluid reservoir for the windshield washers and the rear window washer is shared. The fluid reservoir is

located in the engine compartment, be sure to check the fluid level at regular intervals. Fill the reservoir with windshield washer solvent only (not radiator antifreeze). When refilling the washer fluid reservoir, take some washer fluid and apply it to a cloth or towel and wipe clean the wiper blades, this will help blade performance. To prevent freeze-up of your windshield washer system in cold weather, select a solution or mixture that meets or exceeds the temperature range of your climate. This rating information can be found on most washer fluid containers.

WARNING!

Commercially available windshield washer solvents are flammable. They could ignite and burn you. Care must be exercised when filling or working around the washer solution.

MAINTAINING YOUR VEHICLE 377

Exhaust System The best protection against carbon monoxide entry into the vehicle body is a properly maintained engine exhaust system. If you notice a change in the sound of the exhaust system; or if the exhaust fumes can be detected inside the vehicle; or when the underside or rear of the vehicle is damaged; have an authorized technician inspect the complete ex- haust system and adjacent body areas for broken, dam- aged, deteriorated, or mispositioned parts. Open seams or loose connections could permit exhaust fumes to seep into the passenger compartment. In addition, inspect the exhaust system each time the vehicle is raised for lubri- cation or oil change. Replace as required.

378 MAINTAINING YOUR VEHICLE

WARNING!

Exhaust gases can injure or kill. They contain carbon monoxide (CO), which is colorless and odorless. Breathing it can make you unconscious and can eventually poison you. To avoid breathing CO, refer to “Safety Tips/Exhaust Gas” in “Things To Know Before Starting Your Vehicle” for further informa- tion.

CAUTION!

The catalytic converter requires the use of unleaded fuel only. Leaded gasoline will destroy the effective- ness of the catalyst as an emissions control device and may seriously reduce engine performance and cause serious damage to the engine.

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.

CAUTION!

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.

NOTE: systems can result against you.

Intentional tampering with emissions control in civil penalties being assessed

WARNING!

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 exhaust system. Do not park or operate your vehicle in areas where your exhaust system can contact anything 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 tuneup to manufacturer’s specifica- tions, should be obtained immediately.

MAINTAINING YOUR VEHICLE 379
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, or for prolonged periods during very rough idle or malfunctioning operating conditions.

vehicle.

380 MAINTAINING YOUR VEHICLE Cooling System

WARNING!

You or others can be badly burned by hot engine coolant (antifreeze) or steam from your radiator. If you see or hear steam coming from under the hood, do not open the hood until the radiator has had time to cool. Never try to open a cooling system pressure cap when the radiator or coolant bottle is hot.

Engine Coolant Checks Check the engine coolant (antifreeze) protection every 12 months (before the onset of freezing weather, where applicable). If the engine coolant (antifreeze) is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh engine coolant (anti- freeze). Check the front of the A/C condenser for any

accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from a garden hose vertically down the face of the condenser. Check the engine cooling system hoses for brittle rubber, cracking, tears, cuts, and tightness of the connection at the coolant recovery bottle and radiator. Inspect the entire system for leaks. With the engine at normal operating temperature (but not running), check the cooling system pressure cap for proper vacuum sealing by draining a small amount of engine coolant (antifreeze) from the radiator drain cock. If the cap is sealing properly, the engine coolant (anti- freeze) will begin to drain from the coolant recovery bottle. DO NOT REMOVE THE COOLANT PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT.

Cooling System — Drain, Flush, and Refill If the engine coolant (antifreeze) is dirty and contains a considerable amount of sediment, clean and flush with reliable cooling system cleaner. Follow with a thorough rinsing to remove all deposits and chemicals. Properly dispose of the old engine coolant (antifreeze). Refer to “Maintenance Schedule” for further information. Selection Of Coolant Use only the manufacturer’s recommended engine cool- ant (antifreeze). Refer to “Fluids, Lubricants, and Genu- ine Parts” in “Maintaining Your Vehicle” for further information.

MAINTAINING YOUR VEHICLE 381

CAUTION!

• Mixing of engine coolant (antifreeze), other than the specified HOAT engine coolant (antifreeze), may result in engine damage and may decrease corrosion protection. If a non-HOAT engine cool- ant (antifreeze) is introduced into the cooling system in an emergency, it should be replaced with the specified engine coolant (antifreeze) as soon as possible. • Do not use water alone or alcohol based engine coolant (antifreeze) products. Do not use addi- tional rust inhibitors or antirust products, as they may not be compatible with the engine coolant (antifreeze) and may plug the radiator.

(Continued)

382 MAINTAINING YOUR VEHICLE

CAUTION! (Continued)

• This vehicle has not been designed for use with Propylene Glycol-based engine coolant (anti- freeze). Use of Propylene Glycol-based engine coolant (antifreeze) is not recommended.

Adding Coolant Your vehicle has been built with an improved engine coolant (antifreeze) that allows extended maintenance intervals. This engine coolant (antifreeze) can be used up to 5 Years or 102,000 miles (170 000 km) before replace- ment. To prevent reducing this extended maintenance period, it is important that you use the same engine coolant (antifreeze) throughout the life of your vehicle. Please review these recommendations for using Hybrid Organic Additive Technology (HOAT) engine coolant (antifreeze).

recommends

When adding engine coolant (antifreeze): • The manufacturer

using MOPAR威 Antifreeze/ Coolant 5–Year/100,000 Mile Formula HOAT (Hybrid Organic Additive Technology) or equivalent. • Mix a minimum solution of 50% HOAT engine coolant (antifreeze) and distilled water. Use higher concentra- tions (not to exceed 70%) if temperatures below -34°F (-37°C) are anticipated. • Use only high purity water such as distilled or deion- ized water when mixing the water/engine coolant (antifreeze) solution. The use of lower quality water will reduce the amount of corrosion protection in the engine cooling system.

Please note that it is the owner’s responsibility to main- tain the proper level of protection against freezing ac- cording to the temperatures occurring in the area where the vehicle is operated.

NOTE: Mixing engine coolant (antifreeze) types will decrease the life of the engine coolant (antifreeze) and will require more frequent engine coolant (antifreeze) changes. Cooling System Pressure Cap The cap must be fully tightened to prevent loss of engine coolant (antifreeze), and to ensure that engine coolant (antifreeze) will return to the radiator from the coolant recovery tank. The cap should be inspected and cleaned if there is any accumulation of foreign material on the sealing surfaces.

MAINTAINING YOUR VEHICLE 383

WARNING!

• The warning words DO NOT OPEN HOT on the cooling system pressure cap are a safety precau- tion. Never add engine coolant (antifreeze) when the engine is overheated. Do not loosen or remove the cap to cool an overheated engine. Heat causes pressure to build up in the cooling system. To prevent scalding or injury, do not remove the pressure cap while the system is hot or under pressure. • Do not use a pressure cap other than the one specified for your vehicle. Personal injury or en- gine damage may result.

384 MAINTAINING YOUR VEHICLE Disposal of Used Engine Coolant Used ethylene glycol-based engine coolant (antifreeze) is a regulated substance requiring proper disposal. Check with your local authorities to determine the disposal rules for your community. To prevent ingestion by ani- mals and children, do not store ethylene glycol-based engine coolant (antifreeze) in open containers or allow it to remain in puddles on the ground. If ingested by a child or pet, seek emergency assistance immediately. Clean up any ground spills immediately. Coolant Level The coolant bottle provides a quick visual method for determining that the engine coolant (antifreeze) level is adequate. With the engine idling, and warm to normal operating temperature, the level of the engine coolant (antifreeze) in the bottle should be between the ranges indicated on the bottle.

The radiator normally remains completely full, so there is no need to remove the radiator cap, unless checking for engine coolant (antifreeze) freeze point or replacing en- gine coolant (antifreeze). Advise your service attendant of this. As long as the engine operating temperature is satisfactory, the coolant bottle need only be checked once a month. When additional engine coolant (antifreeze) is needed to maintain the proper level, it should be added to the coolant bottle. Do not overfill. Points To Remember NOTE: When the vehicle is stopped after a few miles (kilometers) of operation, you may observe vapor coming from the front of the engine compartment. This is nor- mally a result of moisture from rain, snow, or high humidity accumulating on the radiator and being vapor- ized when the thermostat opens, allowing hot engine coolant (antifreeze) to enter the radiator.

If an examination of your engine compartment shows no evidence of radiator or hose leaks, the vehicle may be safely driven. The vapor will soon dissipate. • Do not overfill the coolant recovery bottle. • Check engine coolant (antifreeze) freeze point in the radiator and in the coolant recovery bottle. If engine coolant (antifreeze) needs to be added, contents of coolant recovery bottle must also be protected against freezing. • If frequent engine coolant (antifreeze) additions are required, or if the level in the coolant recovery bottle does not drop when the engine cools, the cooling system should be pressure tested for leaks. • Maintain engine coolant (antifreeze) concentration at 50% HOAT engine coolant (antifreeze) (minimum) and distilled water for proper corrosion protection of your engine, which contains aluminum components.

MAINTAINING YOUR VEHICLE 385

bottle hoses are not kinked or obstructed.

• Make sure that the radiator and coolant recovery • Keep the front of the radiator clean. If your vehicle is equipped with air conditioning, keep the front of the condenser clean. • Do not change the thermostat for Summer or Winter operation. If replacement is ever necessary, install ONLY the correct type thermostat. Other designs may result in unsatisfactory cooling performance, poor gas mileage, and increased emissions.

Brake System In order to assure brake system performance, all brake system components should be periodically inspected. Refer to “Maintenance Schedule” for further information.

386 MAINTAINING YOUR VEHICLE

WARNING!

Riding the brakes can lead to brake failure and possibly an accident. Driving with your foot resting or riding on the brake pedal can result in abnormally high brake temperatures, excessive lining wear, and possible brake damage. You would not have your full braking capacity in an emergency.

Fluid Level Check — Brake Master Cylinder The fluid level of the master cylinder should be checked when performing under the hood service, or immedi- ately if the brake system warning lamp indicates system failure. The brake master cylinder has a translucent plastic reservoir. On the outboard side of the reservoir, there is a “MAX” dot and a “MIN” dot. The fluid level must be kept within these two dots. Do not add fluid above the MAX mark, because leakage may occur at the cap.

With disc brakes, the fluid level can be expected to fall as the brake linings wear. However, an unexpected drop in fluid level may be caused by a leak and a system check should be conducted. Refer to “Fluids, Lubricants, and Genuine Parts” in “Maintaining Your Vehicle” for further information.

WARNING!

• Use only manufacturer’s recommended brake fluid. Refer to “Fluids, Lubricants, and Genuine Parts” in “Maintaining Your Vehicle” for further information. Using the wrong type of brake fluid can severely damage your brake system and/or impair its performance. The proper type of brake fluid for your vehicle is also labeled on the origi- nal factory installed hydraulic master cylinder reservoir.

(Continued)

WARNING! (Continued)

• To avoid contamination from foreign matter or moisture, use only new brake fluid or fluid that has been in a tightly closed container. Keep the master cylinder reservoir cap secured at all times. Brake fluid in a open container absorbs moisture from the air resulting in a lower boiling point. This may cause it to boil unexpectedly during hard or prolonged braking, resulting in sudden brake failure. This could result in a accident. • Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts, causing the brake fluid to catch fire. Brake fluid can also damage painted and vinyl surfaces, care should be taken to avoid its contact with these surfaces.

(Continued)

MAINTAINING YOUR VEHICLE 387

WARNING! (Continued)

• Do not allow petroleum based fluid to contami- nate the brake fluid. Brake seal components could be damaged, causing partial or complete brake failure. This could result in an accident.

Front/Rear Axle Fluid

Front Axle Fluid Level Check Lubricant should be to the bottom of the oil fill hole. Rear Axle Fluid Level Check Lubricant should be 1/2 inch (1 cm) below the oil fill hole. Adding Fluid Add lubricant only at the fill hole and only to the level specified above.

388 MAINTAINING YOUR VEHICLE Selection of Lubricant Use only the manufacturer’s recommended fluid. Refer to “Fluids, Lubricants, and Genuine Parts” in “Maintain- ing Your Vehicle” for further information. Transfer Case

Fluid Level Check Inspect the transfer case for fluid leaks. If a fluid leak is found, the transfer case fluid level can be checked by removing the filler plug located on the back side of the transfer case. The fluid level should be at the bottom edge of the filler plug hole when the vehicle is in a level position. Adding Fluid Add fluid at the filler hole, until it runs out of the hole, when the vehicle is in a level position.

Drain First remove fill plug, then remove drain plug. Recom- mended tightening torque for drain and fill plugs is 15 to 25 ft lbs (20 to 34 N·m).

CAUTION!

When installing plugs, do not overtighten. You could damage them and cause them to leak.

Selection of Lubricant Use only the manufacturer’s recommended fluid. Refer to “Fluids, Lubricants, and Genuine Parts” in “Maintain- ing Your Vehicle” for further information.

Automatic Transmission

Selection of Lubricant It is important that the proper lubricant is used in the transmission to assure optimum transmission perfor- mance. Use only the manufacturer’s recommended trans- mission fluid. Refer to “Fluids, Lubricants, and Genuine Parts” in “Maintaining Your Vehicle” for further informa- tion. It is important that the transmission fluid be main- tained at the prescribed level using the recommended fluid.

MAINTAINING YOUR VEHICLE 389

CAUTION!

Using a transmission fluid other than the manufac- turer’s recommended fluid may cause deterioration in transmission shift quality and/or torque converter shudder. Using a transmission fluid other than the manufacturer’s recommended fluid will result in more frequent fluid and filter changes. Refer to “Fluids, Lubricants, and Genuine Parts” in “Main- taining Your Vehicle” for further information.

Special Additives Automatic Transmission Fluid (ATF) is an engineered product and its performance may be impaired by supple- mental additives. Therefore, do not add any fluid addi- tives to the transmission. The only exception to this policy is the use of special dyes to aid in detecting fluid leaks. In addition, avoid using transmission sealers as they may adversely affect seals.

390 MAINTAINING YOUR VEHICLE

CAUTION!

Do not use chemical flushes in your transmission as the chemicals can damage your transmission compo- nents. Such damage is not covered by the New Vehicle Limited Warranty.

Fluid Level Check (3.7L Engine) Regular fluid level checks are not required. For this reason, the dipstick is omitted. If you notice fluid loss or transmission slippage or malfunction, have your authorized dealer check the transmission fluid level.

CAUTION!

• Using a transmission fluid other than the manu- facturer’s recommended fluid may cause deterio- ration in transmission shift quality and/or torque converter shudder. Using a transmission fluid other than that recommended by the manufacturer will result in more frequent fluid and filter changes. Refer to “Fluids, Lubricants, and Genu- ine Parts” in “Maintaining Your Vehicle” for fur- ther information. • The fluid level is preset at the factory and it does not require adjustment under normal operating conditions. If a transmission fluid leak occurs, visit your authorized dealer immediately. Severe damage to the transmission may occur. Your au- thorized dealer has the proper tools to adjust the fluid level accurately.

Fluid Level Check (5.7L Engine) Check the fluid level while the transmission is at normal operating temperature. This occurs after at least 15 miles (25 km) of driving. At normal operating temperature the fluid cannot be held comfortably between the fingertips. To check the fluid level properly, the following procedure must be used: 1. Operate the engine at idle speed and normal operating temperature. 2. The vehicle must be on level ground. 3. Fully apply the parking brake, and press the brake pedal. 4. Place the shift lever momentarily in each gear position ending with the shift lever in PARK. 5. Remove the dipstick, wipe it clean and reinsert it until seated.

MAINTAINING YOUR VEHICLE 391
6. Remove the dipstick again, and note the fluid level on both sides. The fluid level should be between the “HOT” (upper) reference holes on the dipstick at normal operat- ing temperature. The fluid level is only valid if there is a solid coating of oil on both sides of the dipstick. If the fluid is low, add as required into the dipstick tube. Do not overfill. After adding any quantity of oil through the oil fill tube, wait a minimum of two minutes for the oil to fully drain into the transmission before rechecking the fluid level. If it is necessary to check the transmission below NOTE: the operating temperature, the fluid level should be between the two “COLD” (lower) holes on the dipstick with the fluid at approximately 70°F (21°C) (room tem- perature). If the fluid level is correctly established at room temperature, it should be between the “HOT” (upper) reference holes when the transmission reaches 180°F (82°C). Remember it is best to check the level at the normal operating temperature.

392 MAINTAINING YOUR VEHICLE

CAUTION!

Be aware that if the fluid temperature is below 50°F (10°C) it may not register on the dipstick. Do not add fluid until the temperature is elevated enough to produce an accurate reading.

7. Check for leaks. Release parking brake. To prevent dirt and water from entering the transmission after checking or replenishing fluid, make certain that the dipstick cap is properly reseated. It is normal for the dipstick cap to spring back slightly from its fully seated position, as long as its seal remains engaged in the dipstick tube.

Maintenance After Off-Road Driving After extended operation in mud, sand or water, or similar dirty conditions, have your brake discs, brake linings, and axle joints inspected and cleaned as soon as possible. This will prevent any abrasive material from causing excessive wear or unpredictable braking action. After driving off-road, completely inspect the underbody of your vehicle. Check the tires, body structure, steering, suspension and exhaust system for damage. Check threaded fasteners for looseness, particularly on the chassis, drivetrain components, steering and suspension. Retighten, if required, to torque values specified in the Service Manual. Also check for accumulations of vegeta- tion or brush that could become a fire hazard, or conceal damage to fuel lines, brake hoses, axle pinion seals, and propeller shafts.

CAUTION!

Under frequent heavy-duty driving conditions, change all lubricants, and lubricate body compo- nents, all driveline joints and steering linkage more often than in normal service, to prevent excessive wear.

Appearance Care and Protection from Corrosion

Protection of Body and Paint from Corrosion Vehicle body care requirements vary according to geo- graphic locations and usage. Chemicals that make roads passable in snow and ice, and those that are sprayed on trees and road surfaces during other seasons, are highly corrosive to the metal in your vehicle. The following maintenance recommendations will enable you to obtain maximum benefit from the corrosion resistance built into your vehicle.

MAINTAINING YOUR VEHICLE 393

What Causes Corrosion? Corrosion is the result of deterioration or removal of paint and protective coatings from your vehicle. The most common causes are: • Road salt, dirt and moisture accumulation. • Stone and gravel impact. • Insects, tree sap and tar. • Salt in the air near seacoast localities. • Atmospheric fallout/industrial pollutants. Washing • Wash your vehicle regularly. Always wash your ve- hicle in the shade using MOPAR威 Car Wash or a mild car wash soap, and rinse the panels completely with clear water.

394 MAINTAINING YOUR VEHICLE

• If insects, tar, or other similar deposits have accumu- lated on your vehicle, use MOPAR威 Super Kleen Bug and Tar Remover or equivalent to remove. • Use a high quality cleaner wax, such as MOPAR威 Cleaner Wax to remove road film, stains, and to protect your paint finish. Take care never to scratch the paint. • Avoid using abrasive compounds and power buffing that may diminish the gloss or thin out the paint finish.

CAUTION!

• Do not use abrasive or strong cleaning materials such as steel wool or scouring powder, which will scratch metal and painted surfaces.

(Continued)

CAUTION! (Continued)

• Use of power washers exceeding 1,200 psi (8 274 kPa) can result in damage or removal of paint and decals.

Special Care • If you drive on salted or dusty roads or if you drive near the ocean, hose off the undercarriage at least once a month. • It is important that the drain holes in the lower edges of the doors, rocker panels and tailgate must be kept clear and open. • If you detect any stone chips or scratches in the paint, touch them up immediately. The cost of such repairs is considered the responsibility of the owner.

• If your vehicle is damaged due to an accident or similar cause which destroys the paint and protective coating, have your vehicle repaired as soon as pos- sible. The cost of such repairs is considered the respon- sibility of the owner. • If you carry special cargo such as chemicals, fertilizers, de-icer salt, etc., assure that such materials are well packaged and sealed. • If a lot of driving is done on gravel roads, consider • Use MOPAR威 Touch Up Paint or equivalent on scratches or chips as soon as possible. Your authorized dealer has touch up paint to match the color of your vehicle.

mud or stone shields behind each wheel.

MAINTAINING YOUR VEHICLE 395

Wheel and Wheel Trim Care All wheels and wheel trim, especially aluminum and chrome-plated wheels should be cleaned regularly with a mild soap and water to prevent corrosion. To remove heavy soil, use MOPAR威 Wheel Cleaner or select a nonabrasive, non-acidic cleaner. Do not use scouring pads, steel wool, a bristle brush or metal polishes. Only MOPAR威 cleaners or equivalent are recommended. Do not use oven cleaner. Avoid automatic car washes that use acidic solutions or harsh brushes that may damage the wheels’ protective finish. Stain Repel Fabric Cleaning Procedure — If Equipped Stain Repel seats may be cleaned in the following man- ner: • Remove as much of the stain as possible by blotting

with a clean, dry towel.

396 MAINTAINING YOUR VEHICLE

• Blot any remaining stain with a clean, damp towel. • For tough stains, apply MOPAR威 Total Clean or a mild soap solution to a clean, damp cloth and remove the stain. Use a fresh, damp towel to remove soap residue. • For grease stains, apply MOPAR威 Multi-Purpose Cleaner or equivalent to a clean, damp cloth and remove the stain. Use a fresh, damp towel to remove soap residue. • Do not use any harsh solvents or any other form of

protectants on Stain Repel products.

Interior Care Use MOPAR威 Total Clean or equivalent to clean fabric upholstery and carpeting. Interior Trim should be cleaned starting with a damp cloth, a damp cloth with MOPAR威 Total Clean or equiva- lent, then MOPAR威 Spot & Stain Remover or equivalent,

if absolutely necessary. Do not use harsh cleaners or Armor All威. Use MOPAR威 Total Clean or equivalent to clean vinyl upholstery. Leather Seat Care And Cleaning MOPAR威 Total Clean or equivalent is specifically recom- mended for leather upholstery. Your leather upholstery can be best preserved by regular cleaning with a damp soft cloth. Small particles of dirt can act as an abrasive and damage the leather upholstery and should be removed promptly with a damp cloth. Stubborn soils can be removed easily with a soft cloth and MOPAR威 Total Clean or equivalent. Care should be taken to avoid soaking your leather upholstery with any liquid. Please do not use polishes, oils, cleaning fluids, solvents, detergents, or ammonia-based cleaners to clean your leather upholstery. Application of a leather condi- tioner is not required to maintain the original condition.

WARNING!

Do not use volatile solvents for cleaning purposes. Many are potentially flammable, and if used in closed areas, they may cause respiratory harm.

Cleaning Headlights Your vehicle has plastic headlights that are lighter and less susceptible to stone breakage than glass headlights. Plastic is not as scratch-resistant as glass and therefore different lens cleaning procedures must be followed. To minimize the possibility of scratching the lenses and reducing light output, avoid wiping with a dry cloth. To remove road dirt, wash with a mild soap solution fol- lowed by rinsing. Do not use abrasive cleaning components, solvents, steel wool or other aggressive material to clean the lenses.

MAINTAINING YOUR VEHICLE 397

Glass Surfaces All glass surfaces should be cleaned on a regular basis with MOPAR威 Glass Cleaner or any commercial household-type glass cleaner. Never use an abrasive type cleaner. Use caution when cleaning inside rear windows equipped with electric defrosters. Do not use scrapers or other sharp instruments which may scratch the elements. When cleaning the rearview mirror, spray cleaner on the towel or rag that you are using. Do not spray cleaner directly on the mirror. Cleaning Plastic Instrument Cluster Lenses The lenses in front of the instruments in this vehicle are molded in clear plastic. When cleaning the lenses, care must be taken to avoid scratching the plastic. 1. Clean with a wet soft rag. A mild soap solution may be used, but do not use high alcohol content or abrasive cleaners. If soap is used, wipe clean with a clean damp rag.

398 MAINTAINING YOUR VEHICLE 2. Dry with a soft tissue. Seat Belt Maintenance Do not bleach, dye or clean the belts with chemical solvents or abrasive cleaners. This will weaken the fabric. Sun damage will also weaken the fabric. If the belts need cleaning, use MOPAR威 Total Clean, a mild soap solution, or lukewarm water. Do not remove the belts from the vehicle to wash them. Replace the belts if they appear frayed or worn or if the buckles do not work properly. Dry with a soft tissue.

BULB REPLACEMENT

High Intensity Discharge Headlamps (HID) — If Equipped The headlamps are a type of high voltage discharge tube. High voltage can remain in the circuit even with the headlamp switch off and the key removed. Because of this, you should not attempt to service a headlamp bulb yourself. If a headlamp bulb fails, take your vehicle to an authorized dealer for service.

WARNING!

A transient high tension occurs at the bulb sockets of High Intensity Discharge (HID) headlamps when the headlamp switch is turned ON. It may cause serious electrical shock or electrocution if not serviced prop- erly. See your authorized dealer for service.

408 MAINTAINING YOUR VEHICLE NOTE: On vehicles equipped with High Intensity Dis- charge (HID) headlamps, when the headlamps are turned on, there is a blue hue to the lamps. This dimin- ishes and becomes more white after approximately 10 seconds, as the system charges. Halogen Headlamps — If Equipped
