ONBOARD DIAGNOSTIC SYSTEM — OBD II Your vehicle is equipped with a sophisticated onboard diagnostic system called OBD II. This system monitors the performance of the emissions, engine, and automatic transmission control systems. When these systems are operating properly, your vehicle will provide excellent performance and fuel economy, as well as engine emis- sions well within current government regulations. If any of these systems require service, the OBD II system will turn on the “Malfunction Indicator Light.” It will also store diagnostic codes and other information to assist your service technician in making repairs. Al- though your vehicle will usually be drivable and not need towing, see your dealer for service as soon as possible.
CAUTION!
• Prolonged driving with the “Malfunction Indica- tor Light” on could cause further damage to the emission control system. It could also affect fuel economy and driveability. The vehicle must be serviced before any emissions tests can be per- formed. • If the “Malfunction Indicator Light” is flashing while the engine is running, severe catalytic con- verter damage and power loss will soon occur. Immediate service is required.
EMISSIONS INSPECTION AND MAINTENANCE PROGRAMS In some localities, it may be a legal requirement to pass an inspection of your vehicle’s emissions control system. Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and Maintenance) requirement, this check verifies the following: the MIL (Malfunction Indicator Lamp) is functioning and is not on when the engine is running, and that the OBD (On Board Diagnostic) system is ready for testing. Normally, the OBD system will be ready. The OBD system may not be ready if your vehicle was recently serviced, if you recently had a dead battery, or a battery replacement. If the OBD system should be determined not ready for the I/M test, your vehicle may fail the test.
MAINTAINING YOUR VEHICLE 269
Your vehicle has a simple ignition key actuated test which you can use prior to going to the test station. To check if your vehicle’s OBD system is ready, you must do the following: 1. Insert your ignition key into the ignition switch. 2. Turn the ignition to the ON position, but do not crank or start the engine. 3. If you crank or start the engine, you will have to start this test over. 4. As soon as you turn your key to the ON position, you will see your MIL symbol come on as part of a normal bulb check. 5. Approximately 15 seconds later, one of two things will happen:
a. The MIL will flash for about 10 seconds and then return to being fully illuminated until you turn off the
270 MAINTAINING YOUR VEHICLE
ignition key or start the engine. This means that your vehicle’s OBD system is not ready and you should not proceed to the I/M station. b. The MIL will not flash at all and will remain fully illuminated until you turn off the ignition key or start the engine. This means that your vehicle’s OBD system is ready and you can proceed to the I/M station.
If your OBD system is not ready, you should see your authorized dealer or repair facility. If your vehicle was recently serviced or had a battery failure or replacement, you may need to do nothing more than drive your vehicle as you normally would in order for your OBD system to update. A recheck with the above test routine may then indicate that the system is now ready. Regardless of whether your vehicle’s OBD system is ready or not ready, if the MIL symbol is illuminated during normal vehicle operation, you should have your
vehicle serviced before going to the I/M station. The I/M station can fail your vehicle because the MIL symbol is on with the engine running.
REPLACEMENT PARTS Use of genuine Mopar威 parts for normal/scheduled maintenance and repairs is highly recommended to in- sure the designed performance. Damage or failures caused by the use of non-Mopar威 parts for maintenance and repairs will not be covered by the manufacturer’s warranty.
DEALER SERVICE Your dealer has the qualified service personnel, 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.
NOTE: systems can result against you.
Intentional tampering with emissions control in civil penalties being assessed
WARNING!
You can be badly injured working on or around a motor vehicle. Do only that service work for which you have the knowledge and the proper equipment. If you have any doubt about your ability to perform a service job, take your vehicle to a competent mechanic.
MAINTAINING YOUR VEHICLE 271
MAINTENANCE PROCEDURES The pages that follow contain the required maintenance services determined by the engineers who designed your vehicle. Besides the maintenance items for which there are fixed maintenance intervals, there are other items that should operate satisfactorily without periodic maintenance. However, if a malfunction of these items does occur, it could adversely affect the engine or vehicle performance. These items should be inspected if a malfunction is observed or suspected. Engine Oil
Checking Oil Level To assure proper lubrication of your vehicle’s engine, the engine oil must be maintained at the correct level. Check the oil level at regular intervals, such as every fuel stop.
272 MAINTAINING YOUR VEHICLE
The best time to check the engine oil level is about 5
minutes after a fully warmed engine is shut off, or before starting the engine after it has sat overnight. Checking the oil while the vehicle is on level ground will improve the accuracy of the oil level readings. Maintain the oil level between the ADD and SAFE markings on the dipstick. Adding 1 U.S. Quart (0.95L) of oil when the reading is at the ADD mark will result in a SAFE reading 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 Road conditions as well as your kind of driving affect the interval at which your oil should be changed. Check the following to determine if any apply to you: • Day or night temperatures are below 32°F (0°C) • Stop and go driving • Extensive engine idling • Driving in dusty conditions • Short trip driving of less than 10 miles (16.2 km)
speeds during hot weather, above 90°F (32°C)
• More than 50% of your driving is at sustained high • Taxi, Police, or delivery service (commercial service) • Trailer towing • Off-road or desert driving • If equipped for and operating with E–85 (ethanol) fuel If ANY of these apply to you, then change your engine oil at every interval shown in schedule “B” of the “Mainte- nance Schedules” section of this manual. If none of these apply to you, then change your engine oil at every interval shown on schedule “A” of the “Main- tenance Schedules” section of this manual NOTE: Under no circumstances should oil change in- tervals exceed 6,000 miles (10 000 km) or 6 months whichever comes first.
MAINTAINING YOUR VEHICLE 273
Engine Oil Selection For best performance and maximum protection for all engines under all types of operating conditions, the manufacturer recommends engine oils that are API Cer- tified and meet the requirements of DaimlerChrysler Material Standard MS-6395. 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.
274 MAINTAINING YOUR VEHICLE
Engine Oil Viscosity (2.4L Engines) SAE 5W-30 engine oil is recommended for all operating temperatures. This engine oil improves low tempera- ture starting and vehicle fuel economy. Your engine oil filler cap shows the recommended engine oil viscosity for your vehicle.
Engine Oil Viscosity (4.0L Engines) SAE 10W-30 engine oil is recommended for all operat- ing temperatures. This engine oil improves low tem- perature starting and vehicle fuel economy. Your engine oil filler cap shows the recommended engine oil vis- cosity for your vehicle.
Lubricants which do not have both, the engine oil certi- fication mark and the correct SAE viscosity grade num- ber should not be used.
Materials Added To Engine Oils The manufacturer strongly recommends against the ad- dition of any additives (other than leak detection dyes) to engine oil. Engine oil is an engineered product and it’s performance may be impaired by supplemental addi- tives. Disposing of Used Engine Oil Care should be taken in disposing of used engine oil from your vehicle. Used oil, 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 can be safely discarded in your area. Engine Oil Filter The engine oil filter should be replaced 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. Drive Belts — Check Condition and Tension At the mileage shown in the appropriate “Maintenance Schedule,” check all drive belts for condition and proper tension. Improper belt tension can cause belt slippage and failure. Inspect the drive belt for evidence of cuts, cracks, or glazing and replace them if there is any sign of damage which could result in belt failure. If adjustment is re- quired, adjust the belts according to the specifications and procedures shown in the Service Manual.
MAINTAINING YOUR VEHICLE 275
Special tools are required to properly measure tension and to restore belt tension to factory specifications. Also, check belt routing to make sure there is no interference between the belts and other engine components. Spark Plugs Spark plugs must fire properly to assure engine perfor- mance and emission control. New plugs should be in- stalled at the mileage specified in the appropriate main- tenance chart. The entire set should be replaced if there is any malfunction due to a faulty spark plug. Refer to the “Vehicle Emission Control Information” label in the engine compartment for spark plug information. Catalytic Converter The catalytic converter requires the use of unleaded fuel only. Leaded gasoline will destroy the effectiveness of the converter as an emission control device.
276 MAINTAINING YOUR VEHICLE
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.
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 ex- haust system. Do not park or operate your vehicle in areas where your exhaust system can contact any- thing that can burn.
In unusual situations involving grossly malfunctioning engine operation, a scorching odor may suggest severe and abnormal catalyst overheating. If this occurs, stop the vehicle, turn off the engine and allow it to cool. Service, including a tune up to manufacturer’s specifica- tions, should be obtained immediately.
vehicle.
To minimize the possibility of catalytic converter dam- age: • Do not shut off the engine or interrupt the ignition when the transmission is in gear and the vehicle is in motion. • Do not try to start the engine by pushing or towing the • Do not idle the engine with any spark plug wires disconnected or removed, such as when diagnostic testing. • Do not idle the engine for prolonged periods during very rough idle or malfunctioning operating conditions. • Do not allow vehicle to run out of fuel. NOTE: systems can result against you.

Engine Timing Belt — 2.4L Engine
Replace the engine timing belt at the intervals described in the appropriate maintenance schedule. Ignition Wiring System — 2.4L Engine
Replace the ignition cables at the intervals described in the appropriate maintenance schedule. Crankcase Emission Control System Proper operation of this system depends on freedom from sticking or plugging due to deposits. As vehicle mileage builds up, the PCV valve and passages may accumulate deposits. If a valve is not working properly, replace it with a new valve. DO NOT ATTEMPT TO CLEAN THE OLD PCV VALVE! Check ventilation hose for indication of damage or plugging deposits. Replace if necessary.
278 MAINTAINING YOUR VEHICLE
Fuel Filter A plugged fuel filter can cause hard starting or limit the speed at which a vehicle can be driven. Should an excessive amount of dirt accumulate in the fuel tank, frequent replacement of the fuel filter which is mounted in the fuel tank may be necessary. Engine Air Cleaner Filter Under normal driving conditions, replace the air filter at the intervals shown on “Maintenance Schedule A.” If, however, you drive the vehicle frequently under dusty or severe conditions, the filter element should be inspected periodically and replaced if necessary at the intervals shown on “Maintenance Schedule B.”
WARNING!
The air cleaner can provide protection in the case of engine backfire. Do not remove the air cleaner unless it is necessary for repair or maintenance. Make sure that no one is near the engine compart- ment before starting the vehicle with the air cleaner removed. Failure to do so can result in serious personal injury.
Maintenance-Free Battery Your vehicle is equipped with a maintenance-free battery. You will never have to add water, nor is periodic main- tenance required.
WARNING!
Battery posts, terminals, and related accessories con- tain lead and lead compounds. Always wash hands after handling the battery.
MAINTAINING YOUR VEHICLE 279
To determine the battery charge, check the battery test indicator (if equipped) on top of the battery. Refer to the illustration.
CAUTION!
It is essential when replacing the cables on the battery that the positive cable is attached to the positive post and the negative cable is attached to the negative post. Battery posts are marked (+) positive and negative (-) and identified on the battery case. Also, if a “fast charger” is used while battery is in the vehicle, disconnect both vehicle battery cables be- fore connecting the charger to battery. Do not use a “fast charger” to provide starting voltage.
280 MAINTAINING YOUR VEHICLE
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.
WARNING!
• Use only refrigerants and compressor lubricants approved by the manufacturer for your air condi- tioning system. Some unapproved refrigerants are flammable and can explode, injuring you. Other unapproved refrigerants or lubricants can cause the system to fail, requiring costly repairs. Refer to Section 3 of the Warranty Information Book for additional warranty information. • The air conditioning system contains refrigerant under high pressure. To avoid risk of personal injury or damage to the system, adding refrigerant or any repair requiring lines to be disconnected should be done by an experienced repairman.
Refrigerant Recovery and Recycling R-134a Air Conditioning Refrigerant is a hydrofluorocar- bon (HFC) that is endorsed by the Environmental Pro- tection Agency and is an ozone-saving product. How- ever, the manufacturer recommends that air conditioning service be performed by dealers or other service facilities using recovery and recycling equipment. Power Steering Fluid Check Checking the power steering fluid level at a defined service interval is not required. The fluid should only be checked if a leak is suspected, abnormal noises are apparent, and/or the system is not functioning as antici- pated. Coordinate inspection efforts through a certified DaimlerChrysler Dealership.⬙
MAINTAINING YOUR VEHICLE 281
WARNING!
Fluid level should be checked on a level surface with the engine off to prevent injury from moving parts, and to insure accurate fluid level reading. Do not overfill. Use only the manufacturer’s recommended fluid.
If necessary, add fluid to restore to the proper indicated level. With a clean cloth, wipe any spilled fluid from all surfaces. Refer to Fluids, Lubricants, and Genuine Parts for correct fluid type. NOTE: Upon initial start-up in cold weather, the power steering pump may make noise for a short period of time. This is due to the cold, thick fluid in the steering system. This noise should be considered normal, and does not in any way damage the steering system.
282 MAINTAINING YOUR VEHICLE
Driveline And Steering Component Lubrication U-joints (cardan joints) are sealed and do not require lubrication. Prop shafts, yokes, ball joints and other driveline and steering components may be provided with grease fittings for lubrication. Lubrication of these com- ponents at the intervals specified in the appropriate “Maintenance Schedule” in Section 8 is very important, particularly if your vehicle is subjected to off-road or other heavy-duty use. See your authorized dealer for complete service information. Body Lubrication Locks and all body pivot points, including such items as seat tracks, doors, tailgate and hood hinges, should be lubricated periodically to assure quiet, easy operation and to protect against rust and wear. Prior to the appli- cation 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 compo- nents to insure 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 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. Windshield Washers
The fluid reservoir in the engine compartment should be checked for fluid level at regular intervals. Fill the
MAINTAINING YOUR VEHICLE 283
reservoir with windshield antifreeze (not radiator anti- freeze) rated not to freeze at -25°F (-31°C). Operate the system for a few seconds to flush out the residual water.
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;
284 MAINTAINING YOUR VEHICLE
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. Cooling System
WARNING!
You or others can be badly burned by hot antifreeze/ coolant or steam from your radiator. If you see or hear steam coming from under the hood, don’t 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 antifreeze/coolant protection every 12 months (before the onset of freezing weather, where applicable). If antifreeze/coolant is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh antifreeze/coolant. 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 antifreeze/coolant from the radiator drain cock. If the cap is sealing properly, the antifreeze/coolant will begin to drain from the coolant recovery bottle. DO NOT RE- MOVE THE COOLANT PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT. Cooling System — Drain, Flush, And Refill At the intervals shown in the appropriate “Maintenance Schedule,” the system should be drained, flushed, and refilled.
MAINTAINING YOUR VEHICLE 285
If the solution 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 old antifreeze/coolant solution. Discard old antifreeze/coolant solution according to rec- ommended procedure. Selection Of Engine Coolant Use only the manufacturer’s recommended antifreeze/ coolant, refer to Fluids, Lubricants, and Genuine Parts for correct antifreeze/coolant type.
286 MAINTAINING YOUR VEHICLE
CAUTION!
• Mixing of antifreeze/coolant other than the speci- fied HOAT antifreeze/coolant may result in de- creased corrosion protection and engine damage. If a non-HOAT antifreeze/coolant is introduced into the cooling system in an emergency, it should be replaced with the specified antifreeze/coolant as soon as possible. • Do not use plain water alone or alcohol base antifreeze/coolant products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the antifreeze/coolant and may plug the radiator. • This vehicle has not been designed for use with Propylene Glycol based antifreeze/coolant. Use of Propylene Glycol base antifreeze/coolant is not recommended.
Adding Engine Coolant Your vehicle has been built with an improved antifreeze/ coolant that allows extended maintenance intervals. This antifreeze/coolant can be used up to 5 Years or 100,000
miles before replacement. To prevent reducing this ex- tended maintenance period, it is important that you use the same antifreeze/coolant throughout the life of your vehicle. Please review these recommendations for using Hybrid Organic Additive (HOAT) antifreeze/coolant. When adding antifreeze/coolant, a minimum solution of 50% recommended Mopar Antifreeze/ Coolant 5 Year/ 100,000 Mile Formula HOAT (Hybrid Organic Additive Technology), or equivalent, in water should be used. Use higher concentrations (not to exceed 70%) if temperatures below -34°F (-37°C) are anticipated.Technology
Use only high purity water such as distilled or deionized water when mixing the water/antifreeze (coolant) solu- tion. 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 antifreeze/coolant types will decrease the life of the antifreeze/coolant and will require more frequent antifreeze/coolant changes. Cooling System Pressure Cap The cap must be fully tightened to prevent loss of antifreeze/coolant, and to insure that antifreeze/coolant will return to the radiator from the coolant reserve tank.
MAINTAINING YOUR VEHICLE 287
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 antifreeze/coolant 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.
Disposal of Used Engine Coolant Used ethylene glycol based antifreeze/coolant is a regu- lated substance requiring proper disposal. Check with your local authorities to determine the disposal rules for your community. To prevent ingestion by animals or
288 MAINTAINING YOUR VEHICLE
children, do not store ethylene glycol based antifreeze/ coolant in open containers or allow it to remain in puddles on the ground. If ingested by a child, contact a physician immediately. Clean up any ground spills im- mediately. 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 antifreeze/coolant in the bottle should be between the ranges indicated on the bottle. The radiator normally remains completely full, so there is not need to remove the radiator cap unless checking for antifreeze/coolant freeze point or replacing antifreeze/ coolant. 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 antifreeze/coolant is needed to main- tain 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 of operation, you may observe vapor coming from the front of the engine compartment. This is normally a result of moisture from rain, snow, or high humidity accumulat- ing on the radiator and being vaporized when the thermostat opens, allowing hot antifreeze/coolant 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 antifreeze/coolant freeze point in the radiator and in the coolant recovery bottle. If antifreeze/ coolant needs to be added, contents of coolant recov- ery bottle must also be protected against freezing. • If frequent antifreeze/coolant 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 antifreeze/coolant concentration at 50% HOAT antifreeze/coolant (minimum) and distilled water for proper corrosion protection of your engine which contains aluminum components. • 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, also.
bottle hoses are not kinked or obstructed.
MAINTAINING YOUR VEHICLE 289
• 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.
Hoses and Vacuum/Vapor Harnesses Inspect surfaces of hoses and nylon tubing for evidence of heat and mechanical damage. Hard or soft spots, brittle rubber, cracking, tears, cuts, abrasions, and exces- sive swelling indicate deterioration of the rubber. Pay particular attention to the hoses nearest to high heat sources such as the exhaust manifold. Inspect hose rout- ing to be sure hoses do not touch any heat source or moving component that may cause heat damage or mechanical wear. Insure nylon tubing in these areas has not melted or collapsed. Inspect all hose connections such as clamps and couplings to make sure they are secure and no leaks
290 MAINTAINING YOUR VEHICLE
are present. Components should be replaced immedi- ately if there is any evidence of degradation that could cause failure. Brake System In order to assure brake system performance, all brake system components should be inspected periodically. Refer to the appropriate “Maintenance Schedule” in Section 8 for suggested service intervals.
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 wouldn’t have your full braking capacity in an emergency.
Brake and Power Steering System Hoses When servicing the vehicle for scheduled maintenance, inspect surface of hoses for evidence of heat and me- chanical damage. Hard and brittle rubber, cracking, tears, cuts, abrasion, and excessive swelling suggest deteriora- tion of the rubber. Particular attention should be made to examining those hose surfaces nearest to high heat sources, such as the exhaust manifold. Inspect all hose clamps and couplings to make sure they are secure and no leaks are present. Inspection of brake hoses should be done when- NOTE: ever the brake system is serviced and every engine oil change.
WARNING!
Worn brake hoses can burst and cause brake failure. You could have an accident. If you see any signs of cracking, scuffing, or worn spots, have the brake hoses replaced immediately.
Brake Master Cylinder The fluid level in the master cylinder should be checked when performing under hood services, or immediately if the BRAKE warning light shows system failure
MAINTAINING YOUR VEHICLE 291
Be sure to clean the top of the master cylinder area before removing the cap. If necessary, add fluid to bring the fluid level up to the requirements described on the brake fluid reservoir. With disc brakes, fluid level can be expected to fall as the brake pads wear. Brake fluid level
292 MAINTAINING YOUR VEHICLE
should be checked when pads are replaced. However, low fluid level may be caused by a leak and a checkup may be needed. Use only manufacturer’s recommended brake fluid, refer to Fluids, Lubricants, and Genuine Parts for correct fluid type.
WARNING!
• Use of a brake fluid that may have a lower initial boiling point or unidentified as to specification, may result in sudden brake failure during hard prolonged braking. You could have an accident. • Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts and the brake fluid catching fire.
Use only brake fluid that has been in a tightly closed container to avoid contamination from foreign matter. Do not allow petroleum base fluid to contaminate the brake fluid as seal damage will result. 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 manufacturer’s recommended transmis- sion fluid, refer to Fluids, Lubricants, and Genuine Parts for correct fluid type. It is important that the transmission fluid be maintained at the prescribed level using the recommended fluid.
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 for correct fluid type.
Fluid Level Check — 42RLE This fluid level should be checked when the engine is fully warmed up and the fluid in the transmission is heated to its normal operating temperature. Operation of the transmission with an improper fluid level will greatly reduce the life of the transmission and of the fluid.
MAINTAINING YOUR VEHICLE 293
To check the automatic transmission fluid level properly, the following procedure must be used: 1. The vehicle must be on level ground. 2. The engine should be running at curb idle speed for a minimum of 60 seconds. 3. Fully apply parking brake. 4. Apply the brakes and shift the transmission momen- tarily into each gear position ending in P (Park). 5. The fluid MUST be checked with the transmission in P (Park) to be sure that the fluid level is accurate. 6. Wipe the dipstick clean and reinsert until seated. Remove dipstick and note reading. At normal operating temperature (approximately 180° F (82° C), the fluid level is correct if it is in the HOT region

(cross-hatched area) on the oil level indicator. The fluid level indicator should be in the COLD region at 70° F (21° C) fluid temperature. If the fluid level is low, add sufficient fluid to bring to the proper level. Refer to Fluids, Lubricants and Genuine Parts for correct fluid type. Fluid is added through the dipstick tube. NOTE: To prevent dirt and water from entering the transmission after checking or replenishing fluid, make certain that the dipstick cap is properly reseated. Special Additives The manufacturer strongly recommends against the ad- dition of any additives to the transmission. The only exception to this policy is the use of special dyes to aid in detecting fluid leaks. The use of transmission sealers should be avoided as they may adversely affect seals.
Hydraulic Clutch Fluid — Manual Transmission The clutch hydraulic system is a sealed maintenance free system. In the event of leakage or other malfunction, the system must be replaced. Manual Transmission
Selection of Lubricant Use only manufacturer’s recommended manual trans- mission fluid, refer to Fluids, Lubricants, and Genuine Parts for correct fluid type. 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” (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. Fluid changes are not necessary unless the lubricant has become contaminated with water. If con- taminated with water, the fluid should be changed im- mediately. 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.
MAINTAINING YOUR VEHICLE 295
Adding Fluid Fluid should be added only at filler hole until fluid begins to run out of the hole. Drain First remove fill plug (B), then drain plug (C). Recom- mended tightening torque for drain and fill plugs is 15–25 ft.lbs. (20–34 N·m).
296 MAINTAINING YOUR VEHICLE
CAUTION!
Front/Rear Axle Fluid
When replacing plugs, do not overtighten. 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 for correct fluid type.
Fluid Level Check Lubricant should be at bottom edge of the oil fill hole. Adding Fluid Add lubricant only at the fill hole and only to the level specified above.
Selection of Lubricant Use only manufacturer’s recommended fluid, refer to Fluids, Lubricants, and Genuine Parts for correct fluid type. Maintenance After Off-Road Driving After extended operation in mud, sand or water, or similar dirty conditions, have your brake drums, 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. Following off-road usage, completely inspect the under- body of your vehicle. Check tires, body structure, steer- ing, 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
MAINTAINING YOUR VEHICLE 297
damage to fuel lines, brake hoses, axle pinion seals, and propeller shafts. Check air conditioning drain tube on the lower dash wall in the engine compartment for mud or debris, and clean as required. A plugged tube will adversely affect air conditioning performance.
CAUTION!
Under frequent heavy-duty driving conditions, change all lubricants, and lubricate body compo- nents and steering linkage more often than in nor- mal 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
298 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 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 to remove. • Use 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.
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.
MAINTAINING YOUR VEHICLE 299
• 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 possible. The cost of such repairs is considered the responsibil- ity of the owner. • Aluminum 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 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.
300 MAINTAINING YOUR VEHICLE
• 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 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.
Interior Care Use Mopar威 Total Clean to clean fabric upholstery and carpeting. Interior Trim should be cleaned starting with a damp cloth, a damp cloth with Mopar威 Total Clean, then Mopar威 Spot & Stain Remover if absolutely necessary. Do not use harsh cleaners or Armorall. Use Mopar威 Total Clean 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.
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 rear view 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. 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.
MAINTAINING YOUR VEHICLE 301
Replace the belts if they appear frayed or worn or if the buckles do not work properly. Carpet Vacuum your carpet regularly to prevent a soil build-up. Shampoo soiled carpet with a reliable upholstery cleaner, using a natural sponge or soft bristle brush. After carpet dries, vacuum it thoroughly.
WARNING!
Only remove the carpet for cleaning purposes. It provides insulation against high floor pan tempera- tures. You or your passengers could be burned if the carpet is not properly in place. Always put the carpet back into the vehicle before driving.
302 MAINTAINING YOUR VEHICLE
Follow These Steps To Remove The Carpet: 1. Unsnap the front and rear floor carpets. A snap is located on the outboard side of each front seat. 2. Remove the attachment cap from the front footwell area on both the driver and passenger side. The cap is removed by pulling it straight out. 3. Remove the front and rear floor carpets. 4. Remove the cargo floor and wheelhouse carpets. If your vehicle is equipped with an Add-A- NOTE: Trunk™ it must be removed to be able to remove the cargo floor and wheelhouse carpets. For Add-A-Trunk™ removal procedure, refer to “Storage” in Section 3 of this manual. Follow These Steps To Replace The Carpet: 1. Place the front floor carpets in the vehicle.
2. Attach the carpet to the studs in the footwell and press on the attachment caps to secure the carpet. 3. Place rear floor carpet in vehicle and snap rear carpet to front floor carpet. 4. Install wheelhouse carpet followed by the cargo floor carpet. 5. Reinstall Add-A-Trunk™ if so equipped. Appearance Care For Fabric Top Models

sure it is completely dry before lowering.
WASHING — Use Mopar威 Car Wash or mild soap suds, lukewarm water, and a brush with soft bristles. If extra cleaning is required, use Mopar威 Convertible Cloth Top Cleaner or a mild foaming cleaner on the entire top, but support top from underneath. RINSING — Be sure to remove all trace of cleaner by rinsing the top thoroughly with clean water. Remember to allow the top to dry before lowering it.
MAINTAINING YOUR VEHICLE 303
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 will safely clean all plastic windows without scratching. Removes fine scratches to improve visibility and provide 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.
304 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 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 into the zipper teeth. If a stuck zipper slide is experi- enced, work the Mopar威 Soft Top Zipper Cleaner and Lubricant 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.
