RECREATIONAL TOWING (BEHIND MOTORHOME, ETC.)

CAUTION!

Internal damage to the transfer case will occur if a front or rear wheel lift is used when recreational towing.

NOTE: The transfer case must be shifted into N (Neu- tral) for recreational towing.

STARTING AND OPERATING 205

Shifting Into Neutral (N)

Use the following procedure to prepare your vehicle for recreational towing.

CAUTION!

It is necessary to follow these steps to be certain that the transfer case is fully in N (Neutral) before recreational towing to prevent damage to internal parts.

1. Depress brake pedal. 2. Shift automatic transmission into N (Neutral) or de- press clutch pedal on manual transmission. 3. Shift transfer case lever into N (Neutral). 4. Start engine. 5. Shift automatic transmission into D (Drive) or manual transmission into gear.

206 STARTING AND OPERATING

6. Release brake pedal and ensure that there is no vehicle movement. 7. Shut the engine off and place the ignition key into the unlocked OFF position. 8. Shift automatic transmission into P (Park). 9. Apply parking brake. 10. Attach vehicle to the tow vehicle with tow bar. 11. Release parking brake.

CAUTION!

Damage to the transmission may occur if the trans- mission is shifted into P (Park) with the transfer case in N (Neutral) and the engine running. With the transfer case in N (Neutral) ensure that the engine is off prior to shifting the transmission into P (Park) (refer to steps 7 – 8 above).

Shifting Out Of Neutral (N)

Use the following procedure to prepare your vehicle for normal usage. 1. Shift automatic transmission into N (Neutral) or de- press clutch pedal on manual transmission. 2. Shift transfer case lever into desired position. 3. Shift automatic transmission into D (Drive) or release clutch on manual transmissions. NOTE: When shifting out of transfer case N (Neutral) on automatic transmission equipped vehicles, turning the engine off may be required to avoid gear clash.

WARNING!

You or others could be injured if you leave the vehicle unattended with the transfer case in the N (Neutral) position without first fully engaging the parking brake. The transfer case N (Neutral) position disengages both the front and rear driveshafts from the powertrain and will allow the vehicle to move despite the transmission position. The parking brake should always be applied when the driver is not in the vehicle.

STARTING AND OPERATING 207

CAUTION!

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

210 WHAT TO DO IN EMERGENCIES

HAZARD WARNING FLASHER The flasher switch is on top of the steering column, just behind the steering wheel. Depress the switch and both cluster indicators and all front and rear directional sig- nals will flash. Depress the switch again to turn Hazard Warning Flashers off.

Do not use this emergency warning system when the vehicle is in motion. Use it when your vehicle is disabled and is creating a safety hazard for other motorists. If it is necessary to leave the vehicle to go for service, the flasher system will continue to operate with the ignition key removed and the vehicle locked. NOTE: With extended use, the flasher may wear down your battery.

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

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

NOTE: There are steps that you can take to slow down an impending overheat condition. If your air conditioner is on, turn it off. The air conditioning system adds heat to the engine cooling system and turning off the A/C removes this heat. You can also turn the Temperature

Control to maximum heat, the Mode Control to floor, and the Fan Control to High. This allows the heater core to act as a supplement to the radiator and aids in removing heat from the engine cooling system.

CAUTION!

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

CHANGING A FLAT TIRE

Tool Kit Location The jack handle driver and jack extension are located in a kit that is stored on the floor board to the right of the front passenger seat. On some models, this tool kit is under the carpeting in the same location. Jack Location

The jack and lug wrench are stored under the front passenger seat.

212 WHAT TO DO IN EMERGENCIES

To remove the jack from its stowage position, carefully release the rubber strap from the bracket. Turn the thumb screw counterclockwise to loosen jack and then remove it from the bracket.

WARNING!

Always store the jack, lug wrench, jack handle driver, jack extension, and spare, flat or damaged tire securely in the proper place. Never leave them loose in the vehicle where they could become dangerous projectiles during a quick stop or collision.

WARNING!

The jack is designed to use as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes, unless suitable sup- ports are placed under the vehicle as a safety mea- sure. The vehicle should be jacked on a firm level surface only. Avoid ice or slippery areas.

CAUTION!

Never use your vehicle jack on the bumpers, sills or underbody of your vehicle. Damage may result. Place your vehicle jack only under an axle and in the positions shown for “Tire Changing Procedures.”

WHAT TO DO IN EMERGENCIES 213

Tire Changing Procedures

WARNING!

You can be injured or killed if you try to change a wheel too close to moving traffic. Pull far enough off the road to avoid being hit when operating the jack or changing the wheel.

Preparation † Park on a firm, level surface well off the road, to provide ample work space. Place automatic transmis- sion in P (Park), or manual transmission in R (Re- verse), and stop engine. Set parking brake firmly and activate hazard warning flasher.

Spare Tire Location To remove the spare tire from the carrier, remove the tire cover, if equipped, and remove the lug nuts with the lug wrench turning them counterclockwise. If equipped with an anti-theft lug nut (A), use the “Key” (B) and the lug wrench. The “Key” is stored in the glove box.

If you have added aftermarket accessories to the NOTE: spare tire mounted carrier, it cannot exceed a gross weight of 50 lbs (23 kg) including the weight of the spare tire.

214 WHAT TO DO IN EMERGENCIES

† Get everyone out of the vehicle before you jack it up. If the jack should fall, someone in the vehicle could be hurt. † Block tire diagonally oppo- site tire to be changed to pre- vent forward and backward vehicle movement.

JUMP STARTING

WARNING!

To prevent personal injury or damage to clothing, do not allow battery fluid to contact eyes, skin, or fabrics. Do not lean over a battery when connecting jumper cables or allow cable clamps to touch each other. Keep open flames or sparks away from battery vent holes. Always wear eye protection when work- ing with batteries. Do not use a booster battery or any other booster source that has a greater than 12–volt system, i.e. do not use a 24–volt power source.

Your vehicle is equipped with a 12–volt battery. If it becomes necessary to use a booster battery, with jumper cables, to start the vehicle’s engine because it’s battery is discharged, the following procedure should be followed:

Set the parking brake, place an automatic transmission in P (Park) (or N (Neutral) for a manual transmission). Turn off lights, heater, and other electrical loads. Observe charge indicator in the battery. If indicator is light or yellow, replace the battery.

CAUTION!

Use the “Jump Starting” procedure only when the charge indicator is dark in the center. Do not attempt jump starting when the battery charge indicator is bright or yellow. If the charge indicator is dark and has a green dot in the center, failure to start is not due to a discharged battery and the cranking system should be checked.

1. Attach one end of the jumper cable to the positive terminal of the discharged battery and the other end of the same cable to the positive terminal of the booster battery.

WHAT TO DO IN EMERGENCIES 217

WARNING!

Do not permit vehicles to touch each other as this could establish a ground connection and personal injury could result.

2. Connect one end of the other jumper cable to the negative terminal of the booster battery. Connect the other end of the jumper cable to a good ground on the vehicle with the discharged battery. Make sure a good connection is made, free of dirt and grease.

218 WHAT TO DO IN EMERGENCIES

WARNING!

† Do not connect the cable to the negative terminal of the discharged battery. The resulting electrical spark could cause the battery to explode. † During cold weather when temperatures are be- low freezing point, electrolyte in a discharged battery may freeze. Do not attempt jump starting because the battery could rupture or explode. The battery temperature must be brought up above freezing point before attempting to jump start.

3. Take care that the clamps from one cable do not touch clamps from the other cable. Do not lean over the battery when making the connection. The negative connection must provide good electrical conductivity and current carrying capacity.

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

MAINTAINING YOUR VEHICLE 225

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.

226 MAINTAINING YOUR VEHICLE

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

For states which have an I/M (Inspection and Maintenance) requirement, this check verifies the following: the MIL (Malfunction Indicator Lamp) is functioning and is not on when the engine is running, and that the OBD (On Board Diagnostic) system is ready for testing. Normally, the OBD system will be ready. The OBD system may not be ready if your vehicle was recently serviced, if you recently had a dead battery, or a battery replacement. If the OBD system should be determined not ready for the I/M test, your vehicle may fail the test. Your vehicle has a simple ignition key actuated test which you can use prior to going to the test station. To check if your vehicle’s OBD system is ready, you must do the following: 1. Insert your ignition key into the ignition switch.

2. Turn the ignition to the ON position, but do not crank or start the engine. 3. If you crank or start the engine, you will have to start this test over. 4. As soon as you turn your key to the ON position, you will see your MIL symbol come on as part of a normal bulb check. 5. Approximately 15 seconds later, one of two things will happen:

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

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

MAINTAINING YOUR VEHICLE 227

REPLACEMENT PARTS Use of genuine Mopart 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-Mopart 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.

WARNING!

Engine Oil

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

MAINTENANCE PROCEDURES The pages that follow contain the required maintenance services determined by the engineers who designed your vehicle. Besides the maintenance items for which there are fixed maintenance intervals, there are other items that should operate satisfactorily without periodic maintenance. However, if a malfunction of these items does occur, it could adversely affect the engine or vehicle performance. These items should be inspected if a malfunction is observed or suspected.

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. 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)

MAINTAINING YOUR VEHICLE 229

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 intervals exceed 6,000 miles (10 000 km) or 6 months whichever comes first.

230 MAINTAINING YOUR VEHICLE

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 Chart The proper SAE viscosity grade of engine oil should be selected based on the following recommendation and be within the operating temperature shown in the engine oil viscosity chart.

2.4L Engines

MAINTAINING YOUR VEHICLE 231

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. Mopart 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.

4.0L Engines 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.

232 MAINTAINING YOUR VEHICLE

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. 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. 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. 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.

Intentional tampering with emissions control in civil penalties being assessed

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.

234 MAINTAINING YOUR VEHICLE

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 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 235

CAUTION!

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

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

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

236 MAINTAINING YOUR VEHICLE

WARNING!

† Use only refrigerants and compressor lubricants approved by the manufacturer for your air condi- tioning system. Some unapproved refrigerants are flammable and can explode, injuring you. Other unapproved refrigerants or lubricants can cause the system to fail, requiring costly repairs. † 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.

NOTE: Air Conditioning systems found to be contami- nated with A/C System Sealers, Stop Leak Products, Seal Conditioners, Compressor Oil, or Refrigerants not ap- proved by the manufacturer, voids the warranty for the Air Conditioning system. 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.9

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 Recommended Fluids, Lubricants, and Genuine Parts for correct fluid type. 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

MAINTAINING YOUR VEHICLE 237

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 Mopart 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.

238 MAINTAINING YOUR VEHICLE

Windshield Washers

The fluid reservoir in the engine compartment should be checked for fluid level at regular intervals. Fill the 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.

Windshield Washer Aiming To change the aim of the windshield washers, place a safety pin into the nozzle opening and move the nozzle slightly. Continue making slight adjustments until you obtain the desired pattern. Exhaust System The best protection against carbon monoxide entry into the vehicle body is a properly maintained engine exhaust system.

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

WARNING!

You or others can be badly burned by hot 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 radia- tor or coolant bottle is hot.

MAINTAINING YOUR VEHICLE 239

Coolant Checks Check coolant protection every 12 months (before the onset of freezing weather, where applicable). If coolant is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh coolant. Check the front of the radiator for any accumulation of bugs, leaves, etc. Clean the radiator by gently spraying water from a garden hose at the back of the core. Check the engine cooling system hoses for condition and tightness of connection. Inspect the entire system for leaks. Any hoses that show cuts or severe abrasion must be replaced. Cooling System — Drain, Flush, And Refill At the intervals shown in the appropriate “Maintenance Schedule,” the system should be drained, flushed, and refilled. 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.

240 MAINTAINING YOUR VEHICLE

Engine Coolant Disposal Used ethylene glycol based engine coolant is a regulated substance requiring proper disposal. Check with your local authorities to determine the disposal rules for your community. Do not store ethylene glycol based engine coolant in open containers or allow it to remain in puddles on the ground. Prevent ingestion by animals or children. If ingested by a child, contact a physician immediately. Selection Of Coolant Use only the manufacturer’s recommended coolant, refer to Recommended Fluids, Lubricants, and Genuine Parts for correct coolant type.

CAUTION!

† Mixing of coolants other than the specified HOAT coolant may result in decreased corrosion protec- tion and engine damage that may not be covered under the new vehicle warranty. If a non-HOAT coolant is introduced into the cooling system in an emergency, it should be replaced with the speci- fied coolant as soon as possible. † Do not use plain water alone or alcohol base antifreeze products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the radiator coolant and may plug the radiator. † This vehicle has not been designed for use with Propylene Glycol based coolants. Use of Propy- lene Glycol base coolants is not recommended.

Adding Coolant When adding coolant, a minimum solution of recom- mended 50% ethylene glycol antifreeze coolant in water should be used. Use higher concentrations (not to exceed 70%) if temperatures below -37°F (-38°C) are anticipated. Use only high purity water such as distilled or deionized water when mixing the water/antifreeze solution. The use of lower quality water will reduce the amount of corrosion protection in the engine cooling system. NOTE: Mixing coolant types will decrease the life of the engine coolant and will require more frequent engine coolant changes. 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. Cooling System Pressure Cap The cap must be fully tightened to prevent loss of coolant, and to insure that coolant will return to the radiator from the coolant reserve tank.

MAINTAINING YOUR VEHICLE 241

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 coolant when the engine is overheated. Do not loosen or remove the cap to cool an over- heated 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.

the coolant

Coolant Level The coolant bottle provides a quick visual method for determining that is adequate. The coolant level must be at the FULL mark or above the ADD mark on the bottle. The radiator normally remains completely full, so there is not need to remove the radiator cap unless checking for coolant freeze point or replacing coolant. Advise your

level

242 MAINTAINING YOUR VEHICLE

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 coolant is needed to maintain the proper level, it should be added to the coolant bottle. Do not overfill. Points To Remember NOTE: When the vehicle is stopped after a few miles 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 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 coolant freeze point in the system.

† If frequent 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 coolant concentration at 50% ethylene glycol antifreeze (minimum) in water for proper corrosion protection of your engine that contains aluminum components. † Make sure that the radiator and coolant bottle hoses † 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.

are not kinked or obstructed.

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 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.

MAINTAINING YOUR VEHICLE 243

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 NOTE: whenever the brake system is serviced and every engine oil change.

244 MAINTAINING YOUR VEHICLE

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

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 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 Recommended 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 Recommended 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.

MAINTAINING YOUR VEHICLE 245

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 Recommended 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. To check the automatic transmission fluid level properly, the following procedure must be used: 1. The vehicle must be on level ground.

246 MAINTAINING YOUR VEHICLE

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 into 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 Recommended 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 Recommended 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 247

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).

248 MAINTAINING YOUR VEHICLE

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 Recommended Fluids, Lubricants, and Genuine Parts for correct fluid type. 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 Recommended Fluids, Lubricants, and Genuine Parts for correct fluid type. 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. † Bird droppings.

MAINTAINING YOUR VEHICLE 249

lated on your vehicle, wash it as soon as possible.

Washing † Wash your vehicle regularly. Always wash your ve- hicle in the shade using a mild car wash soap and rinse the panels completely with clear water. † If insects, tar, or other similar deposits have accumu- † Use Mopart Auto Polish to remove road film and stains and to polish your vehicle. 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.

250 MAINTAINING YOUR VEHICLE

Appearance Care For Fabric Top Models

CAUTION!

material, as damage may result.

To maintain the appearance of your vehicle’s interior trim and top, follow these precautions: † Avoid leaving your vehicle unattended with the top down, as exposure to sun or rain may damage interior trim. † Do not use harsh cleaners or bleaching agents on top † Do not allow any vinyl cleaner to run down and dry † After cleaning your vehicle’s fabric top, always make † Be especially careful when washing the windows by following the directions for “Care of Fabric Top Win- dows.”

on the paint, leaving a streak.

WASHING — Always use mild soap suds, lukewarm water, and a brush with soft bristles. If extra cleaning is required, use 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. 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 soft cotton cloth moistened with cold or warm, clean water, and wipe across the window, not up and down. 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 Mopart 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 Mopart Soft Top Zipper Cleaner and Lubricant into the zipper teeth. If a stuck zipper slide is experi- enced, work the Mopart Soft Top Zipper Cleaner and Lubricant into the zipper slide. Several applications may be required before the zipper comes free.

MAINTAINING YOUR VEHICLE 251

6. Never paste stickers, gummed labels or any tape to the windows. Adhesives are hard to remove and may dam- age the windows. 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 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

mud or stone shields behind each wheel.

252 MAINTAINING YOUR VEHICLE

† Use Mopart 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. † Aluminum wheels should be cleaned regularly with mild soap and water to prevent corrosion. To remove heavy soil, select a non-abrasive, non-acidic cleaner. Do not use scouring pads or metal polishes. Avoid automatic car washes that use acidic solutions or harsh brushes that may damage the wheels’ protective fin- ish.

Interior Care Use Mopart Fabric Cleaner to clean fabric upholstery and carpeting. Use Mopart Vinyl Cleaner to clean vinyl or leather upholstery. Mopart Vinyl Cleaner is specifically recommended for interior vinyl trim.

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 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 instru- ments 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. 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.

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.

MAINTAINING YOUR VEHICLE 253

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. 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 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.

254 MAINTAINING YOUR VEHICLE

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 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.

EMISSION CONTROL SYSTEM MAINTENANCE The “Scheduled” maintenance services, listed in bold type must be done at the times or mileages specified to assure the continued proper functioning of the emission control system. These, and all other maintenance services included 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 also should be done any time a malfunction is suspected. NOTE: Maintenance, replacement, or repair of the emission control devices and systems on your vehicle may be performed by any automotive repair establish- ment or individual using any automotive part which has been certified pursuant to U.S. EPA or, in the State of California, California Air Resources Board regulations.
