ENGINE COMPARTMENT – 3.8L

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 authorized dealer for service as soon as possible.

MAINTAINING YOUR VEHICLE 379

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 drivability. 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.

380 MAINTAINING YOUR VEHICLE

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 “Malfunction Indicator Light.” Resolving the problem will turn the “Malfunction Indicator Light.” off.

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

For states that require an Inspection and Mainte- nance (I/M), this check verifies the Malfunction Indicator Light (MIL) is functioning and is not on when the engine is running, and that the OBD II system is ready for testing. Normally, the OBD II system will be ready. The OBD II system may not be ready if your vehicle was recently serviced, recently had a dead battery, or a battery replace- ment. If the OBD II system should be determined not ready for the I/M test, your vehicle may fail the test.

Your vehicle has a simple ignition key-actuated test, which you can use prior to going to the test station. To check if your vehicle’s OBD II system is ready, you must do the following: 1. 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 the 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

MAINTAINING YOUR VEHICLE 381

the ignition key 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 key 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 ready, if the MIL is illuminated during normal vehicle operation, you should have your vehicle

382 MAINTAINING 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.

NOTE: systems can result against you.

Intentional tampering with emissions control in civil penalties being assessed

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.

AUTHORIZED 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.

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 mechanic.

MAINTAINING YOUR VEHICLE 383

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.

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. The best time to check the engine oil level is about five minutes after a fully warmed up engine is shut off or before starting the engine after it has sat overnight.

384 MAINTAINING YOUR VEHICLE

CAUTION!

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

Change Engine Oil Refer to the Maintenance Schedule in Section 8 for recommended engine oil change intervals. 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.

Engine Oil Viscosity (3.8L Engines) SAE 5W-20 engine oil is recommended for all operating temperatures. This engine oil improves low temperature starting and vehicle fuel economy. The engine oil filler cap also shows the recommended engine oil viscosity for your engine. For information on engine oil filler cap location, refer to the “Engine Com- partment” illustration in this section.

Lubricants which do not have both, the engine oil certi- fication mark and the correct SAE viscosity grade num- ber, should not be used. 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 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 its 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

MAINTAINING YOUR VEHICLE 385

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.

386 MAINTAINING YOUR VEHICLE

Drive Belts — Check Condition and Tension Belt tension is controlled by means of an automatic tensioner. No belt tension adjustments are required. However, belt and belt tensioner condition should be inspected at the specified intervals, and replaced if re- quired. See your authorized dealer for service At the mileage indicated in the Maintenance Schedule, the condition of all the belts and tensioner should be checked. Refer to Section 8 of this manual. Improper belt tension can cause belt slippage and failure. Belts should be inspected for evidence of cuts, cracks, glazing, or frayed cords and replaced if there is indication of damage, which could result in belt failure. Low generator belt tension can cause battery failure. Also, check belt routing to make sure there is no inter- ference between the belts and other engine components.

Spark Plugs Spark plugs must fire properly to assure engine perfor- mance and emission control. New plugs should be in- stalled at the mileage specified in the Maintenance Sched- ule. Refer to Section 8 of this manual. The entire set should be replaced if there is any malfunction due to a faulty spark plug. Refer to Fluids, Lubricants, and Genu- ine Parts in this section 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. 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!

WARNING!

MAINTAINING YOUR VEHICLE 387

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

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

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

388 MAINTAINING YOUR 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 condi- tions.

vehicle.

• Do not allow vehicle to run out of fuel.

Intentional tampering with emissions control in civil penalties being assessed

NOTE: systems can result against you. Crankcase Emission Control System Proper operation of this system depends on freedom from sticking or plugging due to deposits. As vehicle mileage builds up, the PCV valve and passages may accumulate deposits. If a valve is not working properly, replace it with a new valve. DO NOT ATTEMPT TO CLEAN THE OLD PCV VALVE! Check ventilation hose for indication of damage or plugging deposits. Replace if necessary. 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 Refer to the Maintenance Schedule in Section 8 for recommended engine air cleaner filter change 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.

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 389

WARNING!

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

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 before connecting the charger to battery. Do not use a “fast charger” to provide starting voltage.

390 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 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. 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. 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 an autho- rized DaimlerChrysler Dealership.

MAINTAINING YOUR VEHICLE 391

WARNING!

Fluid level should be checked on a level surface with the engine off to prevent injury from moving parts, and to ensure accurate fluid level reading. Do not overfill. Use only the manufacturer’s recommended power steering 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 in this section 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.

392 MAINTAINING YOUR VEHICLE

Driveline And Steering Component Lubrication All driveline and steering components are sealed and do not require lubrication. Driveshafts are not serviceable. 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 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 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 And Rear Window Washers 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 393

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

394 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. 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 The cooling system should be drained, flushed, and refilled, at the intervals shown on the Maintenance Schedule. Refer to Section 8 of this manual. 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 in this section for correct antifreeze/coolant type.

MAINTAINING YOUR VEHICLE 395

CAUTION!

If

a non-HOAT antifreeze/coolant

• Mixing of antifreeze/coolants other than the speci- fied HOAT antifreeze/coolants, may result in en- gine damage and may decrease corrosion protec- tion. is introduced into the cooling system in an emer- gency, 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/coolants. Use of Propylene Glycol base antifreeze/coolants is not recommended.

396 MAINTAINING YOUR VEHICLE

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
mi (160 000 km) before replacement. To prevent reducing this extended 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 Technology (HOAT) antifreeze/coolant. When adding antifreeze/coolant: • The manufacturer

recommends using MOPAR威 Antifreeze/Coolant 5 Year/100,000 Mile Formula HOAT (Hybrid Organic Additive Technology). • 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 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 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 ensure that antifreeze/coolant 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 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

MAINTAINING YOUR VEHICLE 397

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 no 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.

398 MAINTAINING YOUR VEHICLE

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. • Do not change the thermostat for summer or winter install

operation. If replacement is ever necessary,

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. Ensure 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

MAINTAINING YOUR VEHICLE 399

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 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.

400 MAINTAINING YOUR VEHICLE

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 — Brake Fluid Level Check Refer to Fluids, Lubricants, and Genuine Parts in this section for the correct fluid type.

WARNING!

Use of a brake fluid that may have a lower initial boiling point, or is unidentified as to specification, may result in sudden brake failure during hard prolonged braking. You could have an accident.

Use only brake fluid that has been in a tightly closed container to avoid contamination from foreign matter or moisture.

CAUTION!

Do not allow petroleum base fluid to contaminate the brake fluid. 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 in this section for the correct fluid type. It is important that the transmission fluid be maintained at the pre- scribed level using the recommended fluid.

MAINTAINING YOUR VEHICLE 401

CAUTION!

Using a transmission fluid other than the manufac- turer’s recommended fluid may cause deterioration in transmission shift quality and/or torque converter shudder. Using a transmission fluid other than the manufacturer’s recommended fluid will result in more frequent fluid and filter changes. Refer to Fluids, Lubricants, and Genuine Parts in this section for the correct fluid type.

Fluid Level Check — 42RLE Check the fluid level while the transmission is at normal operating temperature 180° F (82° C). This occurs after at least 15 mi (25 km) of driving. At normal operating temperature the fluid cannot be held comfortably be- tween the fingertips.

402 MAINTAINING YOUR VEHICLE

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 parking brake. 4. Place the gear selector momentarily in each gear position ending with the 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 70° F (21° C) (room tempera- ture). If the fluid level is correctly established at room temperature, it should be between the HOT (upper) reference holes when the transmission reaches 180° F (21° 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.

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

MAINTAINING YOUR VEHICLE 403

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. 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 in this section for the correct fluid type.

404 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. 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.

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 to 25 ft lbs (20 to 34 N·m).

CAUTION!

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 in this section for the correct fluid type.

MAINTAINING YOUR VEHICLE 405

Front/Rear Axle Fluid

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 in this section for the 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.

406 MAINTAINING YOUR VEHICLE

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 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 more often than in normal service to prevent excessive wear.

Appearance Care And Protection From Corrosion

Protection Of Body And Paint From Corrosion Vehicle body care requirements vary according to geo- graphic locations and usage. Chemicals that make roads passable in snow and ice, and those that are sprayed on trees and road surfaces during other seasons, are highly corrosive to the metal in your vehicle. 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.

MAINTAINING YOUR VEHICLE 407

• 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.

408 MAINTAINING YOUR VEHICLE

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 must be kept clear and open.

• If you detect any stone chips or scratches in the paint, touch them up immediately. The cost of such repairs is considered the responsibility of the owner. • If your vehicle is damaged due to an accident or similar cause which destroys the paint and protective coating have your vehicle repaired as soon as possible. The cost of such repairs is considered the responsibil- ity 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 on scratches or chips as soon as possible. Your authorized dealer has touch-up paint to match the color of 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, 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. YES Essentials威 Fabric Cleaning Procedure – If Equipped YES Essentials威 seats may be cleaned in the following manner: • Remove as much of the stain as possible by blotting • Blot any remaining stain with a clean, damp towel.

with a clean, dry towel.

MAINTAINING YOUR VEHICLE 409

• For tough stains, apply MOPAR威 Total Clean or a mild soap solution to a clean, damp cloth and remove stain. Use a fresh, damp towel to remove soap residue. • For grease stains, apply MOPAR威 Multi-Purpose Cleaner to a clean, damp cloth and remove stain. Use a fresh, damp towel to remove soap residue. • Do not use any solvents or protectants on Yes Essen-

tials威 products.

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.

410 MAINTAINING YOUR VEHICLE

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. 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. 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:

on the paint, leaving a streak.

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.

412 MAINTAINING YOUR VEHICLE

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. 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. 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 MO- PAR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. Aggres- sively work the MOPAR威 Soft Top Zipper Cleaner and Lubricant into the zipper teeth. If a stuck zipper slide is experienced, 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.

428 MAINTENANCE SCHEDULES

EMISSIONS CONTROL SYSTEM MAINTENANCE The Scheduled Maintenance services listed in bold type must be done at the times or mileages specified to ensure the continued proper functioning of the emission control system. These, and all other maintenance services in- cluded in this manual, should be done to provide best vehicle performance and reliability. More frequent main- tenance may be needed for vehicles in severe operating conditions, such as dusty areas and very short trip driving. Inspection and service should also be done any time a malfunction is suspected. NOTE: Maintenance, replacement, or repair of the emis- sions control devices and systems on your vehicle may be performed by any automotive repair establishment or individual using any automotive part that has been certified pursuant to U.S. EPA or, in the State of Califor- nia, California Air Resources Board regulations.

MAINTENANCE SCHEDULE The oil change indicator system will remind you that it is time to take your vehicle in for scheduled maintenance. On Non-EVIC equipped vehicles “CHANgE OIL” will flash in the instrument cluster odometer and a single chime will sound, indicating that an oil change is neces- sary. Based on engine operation conditions the oil change indicator message will illuminate, this means that service is required for your vehicle. Have your vehicle serviced as soon as possible, within the next 500 mi (805 km). NOTE: • The oil change indicator message will not monitor the time since the last oil change. Change your vehicles oil if it has been 6 months since your last oil change even if the oil change indicator message is NOT illumi- nated.
