514 MAINTAINING 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” (MIL). 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 authorized dealer for service as soon as possible.

CAUTION!

• Prolonged driving with the MIL on could cause further damage to the emission control system. It could also affect fuel economy and drivability. The vehicle must be serviced before any emissions tests can be performed. • If the MIL is flashing while the engine is running, severe catalytic converter 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 possibly loose, improp- erly installed, or damaged. A “gASCAP” message will be displayed in the odometer. Tighten the gas 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 prob- lem is detected twice in a row, the system will turn on the MIL. Resolving the problem will turn the MIL 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 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.

MAINTAINING YOUR VEHICLE 515
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.

516 MAINTAINING YOUR VEHICLE 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. 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.

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 Service 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.

MAINTAINING YOUR VEHICLE 517

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.

(Continued)

518 MAINTAINING YOUR VEHICLE

CAUTION! (Continued)

• 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.

Engine Oil

Checking Oil Level To assure proper lubrication of your vehicle’s engine, the engine oil must be maintained at the correct level. The engine oil level should be checked five minutes after a warmed up engine has been shut off.

Checking the oil while the vehicle is on level ground will improve the accuracy of the oil level readings. Always maintain the oil level within the SAFE zone on the dipstick. Adding 1 U.S. Quart (0.95L) of oil when the reading is at the bottom of the SAFE zone will result in a reading at the top of the safe zone on these engines.

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 8,000 miles (13 000 km) or six months, whichever occurs 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 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.

MAINTAINING YOUR VEHICLE 519

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 (SAE Grade) SAE 5W-30 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 engine. For information on engine oil filler cap location, refer to “Engine Compart- ment” in “Maintaining Your Vehicle” for further informa- tion. Lubricants which do not have both, the engine oil certi- fication mark and the correct SAE viscosity grade num- ber, should not be used.

520 MAINTAINING YOUR VEHICLE Synthetic Engine Oils Synthetic engine oils can be used if the recommended oil quality requirements are met, and the recommended maintenance intervals for oil and filter changes are followed. Materials Added To Engine Oils Do not add any supplemental materials, other than leak detection dyes, to your engine oil. Engine oil is an engineered product and its performance may be im- paired 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 authorized dealer, service station, or governmental agency for advice on how and where used oil and oil filters can be safely discarded in your area.

Engine Oil Filter The engine oil filter should be replaced with a new filter at every engine 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. Engine Air Cleaner Filter Refer to the “Maintenance Schedule” for the proper maintenance intervals.

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 compartment before starting the vehicle with the air cleaner 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 521

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. Refer to “Jump-Starting Procedures” in “What To Do In Emergencies” for further information. • 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.

522 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 posi- tive (+) and negative (-) and are identified on the battery case. Cable clamps should be tight on the terminal posts and free of corrosion. • If a “fast charger” is used while the 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 tension 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 523

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. A/C Air Filter Refer to the “Maintenance Schedule” for the proper maintenance intervals.

WARNING!

Do not remove the A/C air filter while the blower is operating or personal injury may result.

524 MAINTAINING YOUR VEHICLE The A/C air filter is located in the fresh air inlet behind the glove box. Perform the following procedure to re- place the filter: 1. Open the glove compartment and remove all contents. 2. Push in on the sides of the glove compartment and lower the door. 3. Pivot the glove compartment downward. 4. Disengage the two retaining tabs that secure the two air filter access doors to the HVAC housing.

5. Open the two air filter access doors.

MAINTAINING YOUR VEHICLE 525

CAUTION!

The A/C air filter is identified with an arrow to indicate airflow direction through the filter. Failure to properly install the filter will result in the need to replace it more often.

7. Install the A/C air filter with the air filter position indicators pointing in the same direction as removal. NOTE: Ensure the air filter access door retainers are secure. 8. Rotate the glove compartment door back into position. 7

6. Remove the two particulate air filters from the HVAC air inlet housing. Pull the filter elements straight out of the housing, one at a time.

526 MAINTAINING YOUR VEHICLE 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 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 non-abrasive cleaner. This will remove accumula- tions 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 remove 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 of these conditions are present, clean the wiper blades or replace as necessary. Adding Washer Fluid The fluid reservoir for the windshield washers and the rear window washer (if equipped) 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 anti- freeze). 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 perfor- mance. 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.

MAINTAINING YOUR VEHICLE 527

WARNING!

Commercial windshield washer solvents are flam- mable. They could ignite and burn you. Care must be exercised when filling or working around the washer solution.

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

528 MAINTAINING YOUR VEHICLE 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.

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 information. • 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 ve- hicle in areas where your exhaust system can contact anything that can burn.

CAUTION!

• The catalytic converter requires the use of un- leaded fuel only. Leaded gasoline will destroy the effectiveness of the catalyst as an emissions con- trol device and may seriously reduce engine per- formance and cause serious damage to the engine. • Damage to the catalytic converter can result if your vehicle is not kept in proper operating condition. In the event of engine malfunction, particularly involving engine misfire or other apparent loss of performance, have your vehicle serviced promptly. Continued operation of your vehicle with a severe malfunction could cause the converter to overheat, resulting in possible damage to the converter and vehicle.

Intentional tampering with emissions control in civil penalties being assessed

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. NOTE: systems can result against you. 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.

MAINTAINING YOUR VEHICLE 529
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.

530 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 (if

equipped) or radiator for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from a garden hose vertically down the face of the A/C con- denser (if equipped) or the back of the radiator core. 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 the “Maintenance Schedule” for the proper maintenance intervals. Selection Of Engine 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 531

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 antifreeze/engine coolant (antifreeze) and may plug the radiator. • This vehicle has not been designed for use with (anti- Propylene Glycol based engine coolant freeze). Use of Propylene Glycol base engine cool- ant (antifreeze) is not recommended.

532 MAINTAINING YOUR VEHICLE Adding Engine 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 five years or 104,000 miles (169 000 km) before replacement. To prevent reducing this extended mainte- nance 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). When adding engine coolant (antifreeze): • The manufacturer

recommends 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 and distilled water. Use higher concentrations (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 coolant 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 reserve tank. The cap should be inspected and cleaned if there is any accumulation of foreign material on the sealing surfaces.

WARNING!

The warning words DO NOT OPEN HOT on the cooling system pressure cap are a safety precaution. Never add engine coolant (antifreeze) when the en- gine 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.

MAINTAINING YOUR VEHICLE 533

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 or 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. Engine Coolant Level The coolant bottle provides a quick visual method for determining that the coolant level is adequate. With the engine idling, and warm to normal operating tempera- ture, the level of the engine coolant (antifreeze) in the bottle should be between the ranges indicated on the bottle.

534 MAINTAINING YOUR VEHICLE 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 bottle. • Check the engine coolant (antifreeze) freeze point in the radiator and in the coolant recovery bottle. If engine coolant (antifreeze) needs to be added, the contents of the coolant recovery bottle must also be protected against freezing. • If frequent engine coolant (antifreeze) additions are required, or if the level in the recovery bottle does not drop when the engine cools, the cooling system should be pressure-tested for leaks. • Maintain the 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.

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 inspected periodically. Refer to the “Maintenance Schedule” for the proper maintenance intervals.

MAINTAINING YOUR VEHICLE 535

WARNING!

Riding the brakes can lead to brake failure and possibly a collision. 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.

Power Disc Brakes Disc brakes do not require adjustment; however, several hard stops during the break-in period are recommended to seat the linings and wear off any foreign material. Brake Master Cylinder The fluid level in the master cylinders should be checked whenever the vehicle is serviced. If necessary, add fluid to bring level to the full level mark on the side of the reservoir of the brake master cylinder. With disc brakes,

536 MAINTAINING YOUR VEHICLE fluid level can be expected to fall as the brake pads wear. If the brake fluid level is abnormally low, check system for leaks. 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 identified on the original factory installed hydraulic master cylin- der 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 collision. • 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)

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 a collision.

Automatic Transmission – If Equipped

Selection Of Lubricant It is important that the proper lubricant is used in the transmission to assure optimum transmission perfor- mance. Use only manufacturer’s recommended transmis- sion 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 537

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 require 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.

538 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 Check the fluid level while the transmission is at normal operating temperature 180° F (82° C). This occurs after at least 15 miles (25 km) of driving. At normal operating temperature, the fluid cannot be held comfortably be- tween the fingertips. To properly check the automatic transmission fluid level, 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. 4. Place the shift lever momentarily into each gear posi- tion ending with the shift lever in PARK. 5. Remove the dipstick, wipe it clean and reinsert it until seated. 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. Verify that a solid coating of oil is seen 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 dipstick 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 80° F (27° C). If the fluid level is correctly established at 80° F (27° C), 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.

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.

Selection Of Lubricant Use only manufacturer’s recommended manual trans- mission fluid. Refer to “Fluids, Lubricants, and Genuine Parts” in “Maintaining Your Vehicle” for further information.

540 MAINTAINING YOUR VEHICLE Fluid Level Check Check the fluid level by removing the fill plug. The fluid level should be between the bottom of the fill hole and a point not more than 3/16 in (4.76 mm) below the bottom of the hole. Add fluid, if necessary, to maintain the proper level. Frequency Of Fluid Change Under normal operating conditions, the fluid installed at the factory will give satisfactory lubrication for the life of the vehicle. If the fluid becomes contaminated with water, it should be changed immediately. Otherwise, change the fluid as recommended in the Maintenance Schedule. Refer to the “Maintenance Schedule” for the proper maintenance intervals.

Transfer Case

Fluid Level Check The fluid level should be to the bottom edge of the fill hole (A) when the vehicle is in a level position.

Adding Fluid Fluid should be added only at filler hole until fluid begins to run out of the hole.

Drain First remove the fill plug (B), then the drain plug (C). The recommended tightening torque for the drain and fill plugs is 15 to 25 ft lbs (20 to 34 N·m).

CAUTION!

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

Selection Of Lubricant Use only manufacturer’s recommended fluid. Refer to “Fluids, Lubricants, and Genuine Parts” in “Maintaining Your Vehicle” for further information. Front/Rear Axle Fluid For normal service, periodic fluid level checks are not required. When the vehicle is serviced for other reasons the exterior surfaces of the axle assembly should be inspected.

Refer to “Fluids, Lubricants, and Genuine Parts” in “Maintaining Your Vehicle” for further information. 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

542 MAINTAINING YOUR VEHICLE trees and road surfaces during other seasons, are highly corrosive to the metal in your vehicle. Outside parking, which exposes your vehicle to airborne contaminants, road surfaces on which the vehicle is operated, extreme hot or cold weather and other extreme conditions will have an adverse effect on paint, metal trim, and under- body protection. The following maintenance recommendations will enable you to obtain maximum benefit from the corrosion resistance built into your vehicle. 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 sea-coast localities. • Atmospheric fallout/industrial pollutants. • Bird droppings. Washing • Wash your vehicle regularly. Always wash your ve- hicle in the shade using MOPAR威 Car Wash or equiva- lent, or a mild car wash soap, and rinse the panels completely with clear water. • 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 or equivalent 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. • 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 are kept clear and open.

MAINTAINING YOUR VEHICLE 543

• 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 a collision or similar cause which destroys the paint and protective coating, have your vehicle repaired as soon as possible. The cost of such repairs is considered the responsibility 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 installing mud or stone shields behind each wheel. • 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.

544 MAINTAINING YOUR VEHICLE 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 and/or excessive brake dust, use MOPAR威 Wheel Cleaner or equivalent or select a non-abrasive, non-acidic cleaner.

CAUTION!

Do not use scouring pads, steel wool, a bristle brush, or metal polishes. Do not use oven cleaner. These products may damage the wheel’s protective finish. Avoid automatic car washes that use acidic solutions or harsh brushes that may damage the wheel’s pro- tective finish. Only MOPAR威 Wheel Cleaner or equivalent is recommended.

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.

WARNING!

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

CAUTION!

When installing hanging air fresheners in your ve- hicle, read the installation instructions carefully. Some air fresheners will damage the finish of painted or decorated parts if allowed to directly contact any surface.

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.

MAINTAINING YOUR VEHICLE 545

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. 2. Dry with a soft cloth. 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 or equivalent, a mild soap solution, or lukewarm water. Do not remove the belts from the vehicle to wash them. Dry with a soft cloth.

546 MAINTAINING YOUR VEHICLE Replace the belts if they appear frayed or worn or if the buckles do not work properly. Appearance Care For Fabric Top Models

CAUTION!

To maintain the appearance of your vehicle’s interior trim and top, follow these precautions: • Avoid leaving your vehicle unattended with the top down, as exposure to sun or rain may damage interior trim. • Do not use harsh cleaners or bleaching agents on top • Do not allow any vinyl cleaner to run down and dry • After cleaning your vehicle’s fabric top, always make

sure it is completely dry before lowering.

• Be especially careful when washing the windows by following the directions for “Care of Fabric Top Windows.”

WASHING — Use MOPAR威 Car Wash or equivalent, or mild soap suds, lukewarm water, and a brush with soft bristles. If extra cleaning is required, use MOPAR威 Con- vertible Cloth Top Cleaner or equivalent, or a mild foaming cleaner on the entire top, but support the top from underneath. RINSING — Be sure to remove all traces of cleaner by rinsing the top thoroughly with clean water. Remember to allow the top to dry before lowering it.

CAUTION!

Failure to follow these cautions may cause interior water damage, stains or mildew on the top material:

(Continued)

CAUTION! (Continued)

• Avoid high-pressure car washes, as they can dam- age the top material. Also, increased water pres- sure may force past the weather strips. • It is recommended that the top be free of water prior to opening it. Operating the top, opening a door or lowering a window while the top is wet may allow water to drip into the vehicle’s interior. • Use care when washing the vehicle, water pressure directed at the weather strip seals may cause water to leak into the vehicle’s interior. • Careless handling and storage of the removable roof panels may damage the seals, causing water to leak into the vehicle’s interior. • The front panel(s) must be positioned properly to ensure sealing. Improper installation can cause water to leak into the vehicle’s interior.

MAINTAINING YOUR VEHICLE 547

Care Of Fabric Top Windows

CAUTION!

Your vehicle’s fabric top has pliable plastic windows which can be scratched unless special care is taken by following these directions:

1. Never use a dry cloth to remove dust. Instead, use a microfiber towel or soft cotton cloth moistened with cold or warm, clean water, and wipe across the window, not up and down. MOPAR威 Jeep Soft Glass Window Cleaner or equivalent will safely clean all plastic win- dows without scratching. It removes fine scratches to improve visibility and provides UV protection to help prevent yellowing. 2. When washing, never use hot water or anything stronger than a mild soap. Never use solvents such as alcohol or harsh cleaning agents.

548 MAINTAINING YOUR VEHICLE 3. Always rinse thoroughly with cold water, then wipe with a soft and slightly moist, clean cloth. 4. When removing frost, snow or ice, never use a scraper or de-icing chemicals. Use warm water only if you must clean the window quickly. 5. Debris (sand, mud/dirt, dust, or salt) from off-road driving will have a major impact on zipper operation. Even normal on-road driving and vehicle washing will eventually impact window zipper operation. To maintain ease of use of the window zippers, each window zipper should be cleaned and lubricated regularly. Use MOPAR威 Soft Top Zipper Cleaner and Lubricant or equivalent to ease zipper operation. Before applying,

make sure the zipper teeth are clear of sand, mud, and other materials. Clean both sides of the zipper, not just one side. Rinse both zipper halves with fresh water and allow to dry. Aggressively work the MOPAR威 Soft Top Zipper Cleaner and Lubricant or equivalent into the zipper teeth. If a stuck zipper slide is experienced, work the MOPAR威 Soft Top Zipper Cleaner and Lubricant or equivalent into the zipper slide. Several applications may be required before the zipper comes free. 6. Never paste stickers, gummed labels or any tape to the windows. Adhesives are hard to remove and may dam- age the windows.

CAUTION! (Continued)

• When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system over- load. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected.

CAUTION!

• When installing the Integrated Power Module cover, it is important to ensure the cover is prop- erly positioned and fully latched. Failure to do so may allow water to get into the Integrated Power Module, and possibly result in an electrical system failure.

(Continued)

VEHICLE STORAGE If you are leaving your vehicle dormant for more than 21 days, you may want to take steps to protect your battery. You may: • Remove Cartridge fuse #J13 in the Power Distribution Center (PDC) labeled Ignition-Off Draw (IOD) and store it in a safe location within the PDC.

• Or, disconnect the negative cable from the battery.

• Anytime you store your vehicle, or keep it out of service (i.e., vacation) for two weeks or more, run the air conditioning system at idle for about five minutes in the fresh air and high blower setting. This will ensure adequate system lubrication to minimize the possibility of compressor damage when the system is started again.
