368 WHAT TO DO IN EMERGENCIES
JACKING AND TIRE CHANGING
WARNING!
† Getting under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never get any part of your body under a vehicle that is on a jack. If you need to get under a raised vehicle, take it to a service center where it can be raised on a lift. † 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. The vehicle should be jacked on a firm level surface only. Avoid ice or slippery areas.
Jack Location The scissor-type jack and tire changing tools are located in a compartment behind the third row seat. Refer to “Cargo Area Features” in Section 3 of this manual.
Jack Storage Location
Spare Tire Stowage The spare tire is stowed under the rear of the vehicle by means of a cable winch mechanism. To remove or stow the spare, use the jack handle to rotate the “spare tire drive” nut. The nut is located under a plastic cover at the center-rear of the cargo floor area, just inside the liftgate opening.
CAUTION!
Do not use power tools to winch the tire up or down. Impact type tools can damage the winch mechanism.
WHAT TO DO IN EMERGENCIES 369
Lowering/Raising Spare Tire
Spare Tire Removal Fit the jack handle extension over the drive nut. Use the Lug Wrench to rotate the nut counter clockwise until the spare is on the ground with enough slack in the cable to allow to pull the tire out from under the vehicle.
370 WHAT TO DO IN EMERGENCIES
CAUTION!
WARNING!
The winch mechanism is designed for use with the jack extension tube only. Use of an air wrench or other power tools is not recommended and can dam- age the winch.
Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to avoid being hit when operating the jack or changing the wheel.
When the spare is clear, tilt the retainer at the end of the cable and pull it through the center of the wheel. Preparations For Jacking Park the vehicle on a firm level surface, avoid ice or slippery areas, set the parking brake and place the gear selector in P (Park). Turn OFF the ignition.
† Turn on the Hazard Warning Flasher.
† Block both the front and rear of the wheel diagonally oppo- site of the jacking position. For example, if changing the right front tire, block the left rear wheel. † Passengers should not remain in the vehicle when the
vehicle is being jacked.
Jacking Instructions
1. Remove the spare tire, jack, and tools from storage. 2. Loosen (but do not remove) the wheel lug nuts by turning them to the left one turn while the wheel is still on the ground. 3. Assemble the jack and jacking tools as shown. Connect jack handle driver (A) to two extensions (B), then to the lug wrench (C).

372 WHAT TO DO IN EMERGENCIES
4. Locate the jack as shown. For the front axle, place it under the front lower control arm as shown. For the rear axle, place it under the axle near the wheel to be changed. Ensure the jack is closest to the inside of the wheel when jacking on the rear axle. Do not raise the vehicle until you are sure the jack is fully engaged.
Rear Jacking Location
5. Raise the vehicle by turning the jack screw clockwise. Raise the vehicle only until the tire just clears the surface and enough clearance is obtained to install the spare tire. Minimum tire lift provides maximum stability.
Front Jacking Location
WARNING!
Raising the vehicle higher than necessary can make the vehicle less stable. It could slip off the jack and hurt someone near it. Raise the vehicle only enough to remove the tire.
6. Remove the lug nuts and wheel. 7. Position the spare wheel/tire on the vehicle and install the lug nuts with the cone-shaped end toward the wheel. Lightly tighten the nuts. To avoid the risk of forcing the vehicle off the jack, do not tighten the nuts fully until the vehicle has been lowered. 8. Lower the vehicle by turning the jack screw counter clockwise, and remove the jack and wheel blocks.
WHAT TO DO IN EMERGENCIES 373
9. Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alternate nuts until each nut has been tightened twice. Correct wheel nut tightness is 130 N·m (95 ft. lbs). If in doubt about the correct tightness, have them checked with a torque wrench by your authorized dealer or at a service station. 10. Lower the jack to it’s fully closed position.
WARNING!
A loose tire or jack, thrown forward in a collision or hard stop could endanger the occupants of the ve- hicle. Always stow the jack parts and the spare tire in the places provided.
11. Secure the tire, jack, and tools in their proper loca- tions.
JUMP STARTING If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or the battery in another vehicle. This type of start can be dangerous if done improperly, so follow this procedure carefully.
374 WHAT TO DO IN EMERGENCIES
NOTE: Tire should be stowed with the “beauty” side up. Storing the tire upside down may result in scratching or damage to the wheel face. Continue winching up the tire until you hear the winch “ratchet” three times. Double check to ensure the tire is snug against the underbody of the vehicle. Damage to the winch cable may result if the vehicle is driven with the tire loose.
WARNING!
Do not use power tools to winch the tire up or down. Impact type tools may damage the winch mechanism.
12. Reinstall the rubber plug into the floor of the cargo area.
WARNING!
Battery fluid is a corrosive acid solution; do not allow battery fluid to contact eyes, skin or clothing. Don’t lean over battery when attaching clamps or allow the clamps to touch each other. If acid splashes in eyes or on skin, flush contaminated area immediately with large quantities of water. A battery generates hydrogen gas which is flam- mable and explosive. Keep flame or spark away from the vent holes. 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.
1. Remove all metal jewelry such as watch bands or bracelets which might make an unintended electrical contact.
WHAT TO DO IN EMERGENCIES 375
2. Park the booster vehicle within cable reach but with- out letting the vehicles touch. Set the parking brake on both vehicles, place the transmission in P (Park), and turn the ignition OFF. 3. Turn off the heater, radio, and all unnecessary electri- cal loads. 4. Connect one end of a jumper cable to the positive terminal of the booster battery. Connect the other end of the same cable to the positive terminal of the discharged battery.
WARNING!
Do not permit vehicles to touch each other as this could establish a ground connection and personal injury could result.
376 WHAT TO DO IN EMERGENCIES
5. Connect the other cable, first to the negative terminal of the booster battery and then to the engine of the vehicle with the discharged battery. Make sure you have a good contact on the engine. 6. Start the engine in the vehicle which has the booster battery, let the engine idle a few minutes, then start the engine in the vehicle with the discharged battery. 7. When removing the jumper cables, reverse the above sequence exactly. Be careful of the moving belts and fan.
WARNING!
Any procedure other than above could result in: 1. Personal injury caused by electrolyte squirting out the battery vent; 2. Personal injury or property damage due to battery explosion; 3. Damage to charging system of booster vehicle or of immobilized vehicle.
WARNING!
or towing.
† You should not try to start your vehicle by pushing † Do not connect the cable to the negative post of the discharge 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 jump start.
WHAT TO DO IN EMERGENCIES 377
EMERGENCY TOW HOOKS — IF EQUIPPED If your vehicle is equipped with tow hooks, there will be one in the rear and two mounted on the front of the vehicle. The rear hook will be located on the driver’s side of the vehicle. NOTE: For off-road recovery, it is recommended to use both of the front tow hooks to minimize the risk of damage to the vehicle.
CAUTION!
Tow hooks are for emergency use only, to rescue a vehicle stranded off road. Do not use tow hooks for tow truck hookup or highway towing. You could damage your vehicle.
378 WHAT TO DO IN EMERGENCIES

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 385
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.
386 MAINTAINING YOUR VEHICLE
Loose Fuel Filler Cap Message After fuel is added, the vehicle diagnostic system can determine if the fuel filler cap is loose, improperly installed, or damaged. A “CHECK GASCAP” message will be displayed in the EVIC (Refer to Section 4 of this manual). Tighten the gas cap until a 9clicking9 sound is heard. This is an indication that the gas cap is properly tightened. This message may be temporarily overridden by pressing either the C/T, STEP, or MENU buttons. However, after one minute of no customer interaction, the EVIC will display again the “CHECK GASCAP” message. The message will remain displayed until the vehicle diagnos- tic system can retest the fuel system. The test will perform the next time the vehicle is started, if the vehicle was keyed off above 40°F (4°C) outside temperature and the following vehicle start is above 40°F (4°C) outside temperature. It may be possible to have a message that will not clear due to the test being disabled due to low
outside temperatures. If the test is performed and the problem is gone, the message will disappear. If the problem persists, the message will appear the next time the vehicle is started. This might indicate a damaged cap. If the problem is detected twice in a row, the system will turn on the Malfunction Indicator Light (MIL). Resolving the problem will turn the MIL light off. See your authorized dealer for service.
EMISSIONS INSPECTION AND MAINTENANCE PROGRAMS In some localities, it may be a legal requirement to pass an inspection of your vehicle’s emissions control system. Failure to pass could prevent vehicle registration.
For states 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.
MAINTAINING YOUR VEHICLE 387
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,
388 MAINTAINING YOUR VEHICLE
you may need to do nothing more than drive your vehicle as you normally would in order for your OBD system to update. A recheck with the above test routine may then indicate that the system is now ready. Regardless of whether your vehicle’s OBD system is ready or not ready, if the MIL symbol is illuminated during normal vehicle operation, you should have your vehicle serviced before going to the I/M station. The I/M station can fail your vehicle because the MIL symbol is on with the engine running.
REPLACEMENT PARTS Use of genuine 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!
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.
MAINTAINING YOUR VEHICLE 389
These items should be inspected if a malfunction is observed or suspected. Engine Oil
Checking Oil Level To assure proper engine lubrication, the engine oil must be maintained at the correct level. Check the oil level at regular intervals, such as every fuel stop. The best time to check the engine oil level is about 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 in the SAFE level range. Adding 1 U.S. Quart (0.95L) of oil when the level is at the bottom of the SAFE range will result in the level being at the top of the SAFE range.
390 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 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 only recommends engine oils that are API Certified 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 (3.7L/4.7L/5.7L Engines) SAE 5W-20 engine oil is recommended for all operating temperatures. This engine oil improves low temperature starting and vehicle fuel economy. The engine oil filler cap also shows the recommended engine oil viscosity for your vehicle. For information on engine oil filler cap location, refer to the “Engine Compartment” illustration in this section.
NOTE: Vehicles equipped with a 5.7L engine must use SAE 5W-20 oil. Failure to do so may result in improper operation of the Multiple Displacement System (MDS). Refer to “Multi Displacement System” in Section 5 for more details. 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 You may use synthetic engine oils provided the recom- mended oil quality requirements are met, and the recom- mended 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
MAINTAINING YOUR VEHICLE 391
engine oil. Engine oil is an engineered product and it’s performance may be impaired by supplemental addi- tives. Disposing of Used Engine Oil and Oil Filters Care should be taken in disposing of the used engine oil and oil filters from your vehicle. Used oil and oil filters, indiscriminately discarded, can present a problem to the environment. Contact your local authorized dealer, ser- vice station, or governmental agency for advice on how and where used oil and oil filters can be safely discarded in your area. Engine Oil Filter The engine oil filter should be replaced with a new filter at every oil change.
392 MAINTAINING YOUR VEHICLE
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 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, all belts and tensioner should be checked for condition. 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 gen- erator 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 spark plugs should be installed at the specified mileage. The entire set should be replaced if there is any malfunction due to a faulty spark plug. Refer to “Fluids, Lubricants, and Genuine Parts” in this section for spark plug information. Spark Plug Wires The spark plug wires should be kept clean and properly connected. Terminals should be fully seated. Cracked, damaged, or faulty wires should be replaced.
Engine Air Cleaner Filter Refer to the Maintenance Schedule for recommended Engine Air Cleaner Filter change intervals.
WARNING!
The air induction system (air cleaner, hoses, etc) can provide a measure of protection in the case of engine backfire. Do not remove the air induction system (air cleaner, hoses, etc) unless such removal is necessary for repair or maintenance. Make sure that no one is near the engine compartment before starting the vehicle with the air induction system (air cleaner, hoses, etc) removed. Failure to do so can result in serious personal injury.
MAINTAINING YOUR VEHICLE 393
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.
394 MAINTAINING YOUR VEHICLE
CAUTION!
WARNING!
Damage to the catalytic converter can result if your vehicle is not kept in proper operating condition. In the event of engine malfunction, particularly involv- ing engine misfire or other apparent loss of perfor- mance, have your vehicle serviced promptly. Contin- ued operation of your vehicle with a severe malfunction could cause the converter to overheat, resulting in possible damage to the converter and vehicle.
NOTE: systems can result against you.
Intentional tampering with emissions control in civil penalties being assessed
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.
To minimize the possibility of catalytic converter dam- age: † Do not shut off the engine or interrupt the ignition when the transmission is in gear and the vehicle is in motion. † Do not try to start the engine by pushing or towing the † Do not idle the engine with any spark plug wires disconnected or removed, such as when diagnostic testing, or for prolonged periods during very rough idle or malfunctioning operating conditions.

CAUTION!
Do not use Automatic Transmission Fluid (ATF) or other types of power steering fluids when servicing the power steering system of this vehicle. Damage to the power steering system can result from the use of the wrong power steering fluid.
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.”
WARNING!
Fluid level should be checked on a level surface with the engine off to prevent injury from moving parts, and to insure accurate fluid level reading. Do not overfill. Use only the manufacturer’s recommended fluid.
If necessary, add fluid to restore to the proper indicated level. With a clean cloth, wipe any spilled fluid from all surfaces. Refer to Fluids, Lubricants, and Genuine Parts for correct fluid type. NOTE: Upon initial start-up in cold weather, the power steering pump may make noise for a short period of time. This is due to the cold, thick fluid in the steering system. This noise should be considered normal, and does not in any way damage the steering system.
MAINTAINING YOUR VEHICLE 399
Body Lubrication Locks and all body pivot points, including such items as seat tracks, doors, tailgate and hood hinges, should be lubricated periodically to assure quiet, easy operation and to protect against rust and wear. Prior to the appli- cation of any lubricant, the parts concerned should be wiped clean to remove dust and grit; after lubricating excess oil and grease should be removed. Particular attention should also be given to hood latching compo- nents to insure proper function. When performing other underhood services, the hood latch, release mechanism and safety catch should be cleaned and lubricated. The external lock cylinders should be lubricated twice a year, preferably in the fall and spring. Apply a small amount of a high quality lubricant such as Mopart Lock Cylinder Lubricant directly into the lock cylinder.

Windshield Wiper Blades The rubber edges of the wiper blades and the windshield should be cleaned periodically with a sponge or soft cloth and a mild nonabrasive cleaner to remove accumulations of salt or road film. Operation of the wipers on dry glass for long periods may cause deterioration of the wiper blades. Always use washer fluid when using the wipers to remove salt or dirt from a dry windshield. Avoid using the wiper blades to wipe frost or ice from the windshield. Keep the blade rubber out of contact with petroleum products such as engine oil, gasoline, etc. Windshield Washers — Front and Rear On vehicles equipped with a Electronic Vehicle Informa- tion Center (EVIC), the low washer fluid level will be indicated. When the sensor detects a low fluid level, the windshield will light on the vehicle graphic outline and the “Washer Fluid Low” message will be displayed.
The fluid reservoir for the windshield washers and the rear window washer is shared. The fluid reservoir is located in the engine compartment, be sure to check the fluid level at regular intervals. Fill the reservoir with windshield washer solvent only (not radiator antifreeze). When refilling the washer fluid reservoir, take some washer fluid and apply it to a cloth or towel and wipe clean the wiper blades, this will help blade performance. To prevent freeze-up of your windshield washer system in cold weather, select a solution or mixture that meets or exceeds the temperature range of your climate. This rating information can be found on most washer fluid containers.
WARNING!
Commercially available windshield washer solvents are flammable. They could ignite and burn you. Care must be exercised when filling or working around the washer solution.
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
MAINTAINING YOUR VEHICLE 401
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
402 MAINTAINING YOUR VEHICLE
system should be drained, flushed and refilled with fresh antifreeze/coolant. Check the front of the A/C condenser for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from a garden hose vertically down the face of the condenser. Check the engine cooling system hoses for brittle rubber, cracking, tears, cuts, and tightness of the connection at the coolant recovery bottle and radiator. Inspect the entire system for leaks. With the engine at normal operating temperature (but not running), check the cooling system pressure cap for proper vacuum sealing by draining a small amount of 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 REMOVE THE COOLANT PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush, And Refill At the intervals shown on the 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. Properly dispose of old antifreeze/coolant solution. Selection Of Coolant Use only the manufacturer’s recommended antifreeze/ coolant, refer to Fluids, Lubricants, and Genuine Parts for correct antifreeze/coolant type.
CAUTION!
Mixing of antifreeze/coolant other than the specified HOAT antifreeze/coolant may result in decreased corrosion protection and engine damage. If a non- HOAT antifreeze/coolant is introduced into the cool- ing system in an emergency, it should be replaced with the specified antifreeze/coolant as soon as pos- sible. Do not use plain water alone or alcohol base antifreeze/coolant products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the antifreeze/coolant and may plug the radiator. This vehicle has not been designed for use with Propylene Glycol based antifreeze/coolant. Use of Propylene Glycol base antifreeze/coolant is not recommended.
MAINTAINING YOUR VEHICLE 403
Adding Coolant Your vehicle has been built with an improved antifreeze/ coolant that allows extended maintenance intervals. This antifreeze/coolant can be used up to 5 Years or 100,000
miles (160 000 km) before replacement. To prevent reduc- ing 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 manufacturerrecommends using Mopart 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%) temperatures below -34°F (-37°C) are anticipated.
if
404 MAINTAINING YOUR VEHICLE
† Use only high purity water such as distilled or deion- ized water when mixing the water/antifreeze (cool- ant) 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 insure that antifreeze/coolant will return to the radiator from the coolant recovery tank.
The cap should be inspected and cleaned if there is any accumulation of foreign material on the sealing surfaces.
WARNING!
† The warning words DO NOT OPEN HOT on the cooling system pressure cap are a safety precau- tion. Never add antifreeze/coolant when the en- gine is overheated. Do not loosen or remove the cap to cool an overheated engine. Heat causes pressure to build up in the cooling system. To prevent scalding or injury, do not remove the pressure cap while the system is hot or under pressure. † Do not use a pressure cap other than the one specified for your vehicle. Personal injury or en- gine damage may result.
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 and 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. Coolant Level The coolant bottle provides a quick visual method for determining that the antifreeze/coolant level is adequate. With the engine idling, and warm to normal operating temperature, the level of the antifreeze/coolant in the bottle should be between the ranges indicated on the bottle.
MAINTAINING YOUR VEHICLE 405
The radiator normally remains completely full, so there is not need to remove the radiator cap unless checking for antifreeze/coolant freeze point or replacing antifreeze/ coolant. Advise your service attendant of this. As long as the engine operating temperature is satisfactory, the coolant bottle need only be checked once a month. When additional antifreeze/coolant is needed to main- tain the proper level, it should be added to the coolant bottle. Do not overfill. Points To Remember NOTE: When the vehicle is stopped after a few miles (kilometers) of operation, you may observe vapor coming from the front of the engine compartment. This is nor- mally a result of moisture from rain, snow, or high humidity accumulating on the radiator and being vapor- ized when the thermostat opens, allowing hot antifreeze/ coolant to enter the radiator.
406 MAINTAINING YOUR VEHICLE
If an examination of your engine compartment shows no evidence of radiator or hose leaks, the vehicle may be safely driven. The vapor will soon dissipate. † Do not overfill the coolant recovery bottle. † Check 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 coolant 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.
bottle hoses are not kinked or obstructed.
† Make sure that the radiator and coolant recovery † Keep the front of the radiator clean. If your vehicle is equipped with air conditioning, keep the front of the condenser clean, 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. 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. Fuel System Connections Electronic Fuel Injection high pressure fuel systems are designed with tubes and special connects, connections and clamps which have unique material characteristics to provide adequate sealing and resist attack by deterio- rated gasoline.
MAINTAINING YOUR VEHICLE 407
You are urged to use only the manufactures-specified tubes, connections and clamps, or their equivalent in material and specification, in any fuel system servicing. 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.
408 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. NOTE: Often fluids such as oil, power steering fluid, and brake fluid are used during assembly plant opera- tions to ease the assembly of hoses to couplings. There- fore, oil wetness at the hose-coupling area is not neces- sarily an indication of leakage. Actual dripping of hot fluid when systems are under pressure (during vehicle operation) should be noted before hose is replaced based on leakage.
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 The fluid level in the master cylinder should be checked when performing under hood services, or immediately if the brake system warning lamp 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. However, low fluid level may be caused by a leak and a checkup may be needed. Use only manufacturer’s recommended brake fluid, refer to Fluids, Lubricants, and Genuine Parts for correct fluid type.
WARNING!
Use of a brake fluid that may have a lower initial boiling point or unidentified as to specification, may result in sudden brake failure during hard prolonged braking. You could have an accident.
MAINTAINING YOUR VEHICLE 409
WARNING!
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 or moisture.
CAUTION!
Do not allow petroleum base fluid to contaminate the brake fluid as seal damage will result.
410 MAINTAINING YOUR VEHICLE
Front/Rear Axle Fluid
Front Axle Fluid Level Check Lubricant should be to the bottom of the oil fill hole. Rear Axle Fluid Level Check Lubricant should be 1/2” (1 cm) below the oil fill hole. Adding Fluid Add lubricant only at the fill hole and only to the level specified above. Selection of Lubricant Use only manufacturer’s recommended fluid, refer to Fluids, Lubricants, and Genuine Parts for correct fluid type.
Transfer Case
Fluid Level Check Inspect the transfer case for fluid leaks. If a fluid leak is found, the transfer case fluid level can be checked by removing the filler plug located on the back side of the transfer case. The fluid level should be at the bottom edge of the filler plug hole when the vehicle is in a level position. Adding Fluid Add fluid at the filler hole until it runs out of the hole when the vehicle is in a level position. Drain First remove fill plug, then remove drain plug. Recom- mended tightening torque for drain and fill plugs is 15–25 ft. lbs (20–34 N·m).
CAUTION!
When installing plugs, do not overtighten. You could damage them and cause them to leak.
Selection of Lubricant Use only manufacturer’s recommended fluid, refer to Fluids, Lubricants, and Genuine Parts for correct fluid type. 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
MAINTAINING YOUR VEHICLE 411
for correct fluid type. It is important that the transmission fluid be maintained at the prescribed level using the recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac- turer’s recommended fluid may cause deterioration in transmission shift quality and/or torque converter shudder. Using a transmission fluid other than the manufacturer’s recommended fluid will result in more frequent fluid and filter changes. Refer to Fluids, Lubricants, and Genuine Parts for correct fluid type.
Fluid Level Check (3.7L Engine) Regular automatic transmission fluid level checks are not required. For this reason, the dipstick is omitted.
412 MAINTAINING YOUR VEHICLE
If you notice fluid loss or gear shift malfunction, have your authorized dealer check the transmission fluid level.
CAUTION!
The fluid level is preset at the factory and it does not require adjustment under normal operating condi- tions. If a transmission fluid leak occurs, visit your authorized dealer immediately. Severe damage to the transmission may occur. Your authorized dealer has the proper tools to adjust the fluid level accurately.
Fluid Level Check (4.7L and 5.7L Engine) Check the fluid level while the transmission is at normal operating temperature. This occurs after at least 15 miles (25 km) of driving. At normal operating temperature the fluid cannot be held comfortably between the fingertips.
To check the automatic transmission fluid level properly, the following procedure must be used: 1. Operate the engine at idle speed and normal operating temperature. 2. The vehicle must be on level ground. 3. Fully apply the parking brake and press the brake pedal. 4. Place the gear selector momentarily in each gear position ending with the lever in P (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. The fluid level is only valid if there is 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 oil fill tube, wait a minimum of two (2) minutes for the oil to fully drain into the transmission before rechecking the fluid level. If it is necessary to check the transmission below NOTE: the operating temperature, the fluid level should be between the two “COLD” (lower) holes on the dipstick with the fluid at approximately 70°F (21°C) (room tem- perature). If the fluid level is correctly established at room temperature, it should be between the “HOT” (upper) reference holes when the transmission reaches 180°F (82°C). Remember it is best to check the level at the normal operating temperature.
MAINTAINING YOUR VEHICLE 413
CAUTION!
Be aware that if the fluid temperature is below 50°F (10°C) it may not register on the dipstick. Do not add fluid until the temperature is elevated enough to produce an accurate reading.
7. Check for leaks. Release parking brake. To prevent dirt and water from entering the transmission after checking or replenishing fluid, make certain that the dipstick cap is properly reseated. It is normal for the dipstick cap to spring back slightly from its fully seated position, as long as its seal remains engaged in the dipstick tube.
414 MAINTAINING YOUR VEHICLE
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. Maintenance After Off-Road Driving After extended operation in mud, sand or water, or similar dirty conditions, have your brake discs, brake linings, and axle joints inspected and cleaned as soon as possible. This will prevent any abrasive material from causing excessive wear or unpredictable braking action.
After off-road driving, completely inspect the underbody of your vehicle. Check tires, body structure, steering, suspension and exhaust system for damage. Check threaded fasteners for looseness, particularly on the chassis, drivetrain components, steering and suspension. Retighten, if required, to torque values specified in the Service Manual. Also check for accumulations of vegeta- tion or brush that could become a fire hazard, or conceal damage to fuel lines, brake hoses, axle pinion seals, and propeller shafts.
CAUTION!
Under frequent heavy-duty driving conditions, change all lubricants and lubricate body compo- nents, all driveline joints and steering linkage more often than in normal service to prevent excessive wear.
Appearance Care And Protection From Corrosion
Protection of Body and Paint from Corrosion Vehicle body care requirements vary according to geo- graphic locations and usage. Chemicals that make roads passable in snow and ice, and those that are sprayed on trees and road surfaces during other seasons, are highly corrosive to the metal in your vehicle. The following maintenance recommendations will enable you to obtain maximum benefit from the corrosion resistance built into your vehicle. 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.
MAINTAINING YOUR VEHICLE 415
† Salt in the air near seacoast localities. † Atmospheric fallout/industrial pollutants. Washing † Wash your vehicle regularly. Always wash your ve- hicle in the shade using Mopart 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 Mopart Super Kleen Bug and Tar Remover to remove. † Use Mopart 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.
416 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 † 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.
mud or stone shields behind each wheel.
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 Mopart Wheel Cleaner or select a non- abrasive, non-acidic cleaner. Do not use scouring pads, steel wool, a bristle brush or metal polishes. Only Mo- part 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. Interior Care Use Mopart Total Clean to clean fabric upholstery and carpeting. Interior Trim should be cleaned starting with a damp cloth, a damp cloth with Mopart Total Clean, then
MAINTAINING YOUR VEHICLE 417
Mopart Spot & Stain Remover if absolutely necessary. Do not use harsh cleaners or Armorall. Use Mopart Total Clean to clean vinyl upholstery. Leather Seat Care & Cleaning Mopart Total Clean is specifically recommended for leather upholstery. Your leather upholstery can be best preserved by regular cleaning with a damp soft cloth. Small particles of dirt can act as an abrasive and damage the leather upholstery and should be removed promptly with a damp cloth. Stubborn soils can be removed easily with a soft cloth and Mopart Total Clean. Care should be taken to avoid soaking your leather upholstery with any liquid. Please do not use polishes, oils, cleaning fluids, solvents, deter- gents, or ammonia based cleaners to clean your leather upholstery. Application of a leather conditioner is not required to maintain the original condition.
418 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.
Cleaning Headlights Your vehicle has plastic headlights that are lighter and less susceptible to stone breakage than glass headlights. Plastic is not as scratch resistant as glass and therefore different lens cleaning procedures must be followed. To minimize the possibility of scratching the lenses and reducing light output, avoid wiping with a dry cloth. To remove road dirt, wash with a mild soap solution fol- lowed by rinsing. Do not use abrasive cleaning components, solvents, steel wool or other aggressive material to clean the lenses.
Glass Surfaces All glass surfaces should be cleaned on a regular basis with Mopart Glass Cleaner or any commercial household-type glass cleaner. Never use an abrasive type cleaner. Use caution when cleaning inside rear windows equipped with electric defrosters. Do not use scrapers or other sharp instruments which may scratch the elements. When cleaning the rear view mirror, spray cleaner on the towel or rag that you are using. Do not spray cleaner directly on the mirror. Cleaning Plastic Instrument Cluster Lenses The lenses in front of the instruments in this vehicle are molded in clear plastic. When cleaning the lenses, care must be taken to avoid scratching the plastic. 1. Clean with a wet soft rag. A mild soap solution may be used, but do not use high alcohol content or abrasive cleaners. If soap is used, wipe clean with a clean damp rag.
2. Dry with a soft tissue. Seat Belt Maintenance Do not bleach, dye or clean the belts with chemical solvents or abrasive cleaners. This will weaken the fabric. Sun damage will also weaken the fabric. If the belts need cleaning, use Mopart Total Clean, a mild soap solution, or lukewarm water. Do not remove the belts from the vehicle to wash them. Replace the belts if they appear frayed or worn or if the buckles do not work properly. Dry with a soft tissue.
