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.
382 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 pro- longed braking. You could have an accident.
MAINTAINING YOUR VEHICLE 383
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.

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).
MAINTAINING YOUR VEHICLE 385
CAUTION!
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 for correct fluid type. It is important that the transmission fluid be maintained at the prescribed level using the recommended fluid.
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
If equipped with a dipstick, use the following NOTE: procedure. If your vehicle has a capped dipstick tube, it is sealed and should not be tampered with. Your autho- rized dealer has the proper tools to ensure that the fluid level is set properly.
386 MAINTAINING YOUR VEHICLE
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.
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.
MAINTAINING YOUR VEHICLE 387
Special Additives The manufacturer recommends against the addition of any additives to the transmission. Exception to this policy is the use of special dyes to aid in detecting fluid leaks. 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
388 MAINTAINING YOUR VEHICLE
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. • 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 Mopar威 Car Wash or a mild car wash soap, and rinse the panels completely with clear water. • If insects, tar, or other similar deposits have accumu- lated on your vehicle, use Mopar威 Super Kleen Bug and Tar Remover to remove. • Use Mopar威 Cleaner Wax to remove road film, stains, and to protect your paint finish. Take care never to scratch the paint. • Avoid using abrasive compounds and power buffing that may diminish the gloss or thin out the paint finish.
MAINTAINING YOUR VEHICLE 389
CAUTION!
Do not use abrasive or strong cleaning materials such as steel wool or scouring powder, which will scratch metal and painted surfaces.
Special Care • If you drive on salted or dusty roads or if you drive near the ocean, hose off the undercarriage at least once a month. • It is important that the drain holes in the lower edges of the doors, rocker panels and tailgate must be kept clear and open.
390 MAINTAINING YOUR VEHICLE
• 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 Mopar威 Touch Up Paint on scratches or chips as soon as possible. Your authorized dealer has touch up paint to match the color of your vehicle.
mud or stone shields behind each wheel.
Wheel and Wheel Trim Care All wheels and wheel trim, especially aluminum and chrome plated wheels should be cleaned regularly with a mild soap and water to prevent corrosion. To remove heavy soil, use Mopar威 Wheel Cleaner or select a nonabra- sive, non-acidic cleaner. Do not use scouring pads, steel wool, a bristle brush or metal polishes. Only Mopar威 cleaners are recommended. Do not use oven cleaner. Avoid automatic car washes that use acidic solutions or harsh brushes that may damage the wheels’ protective finish. Interior Care Use Mopar威 Total Clean to clean fabric upholstery and carpeting. Interior Trim should be cleaned starting with a damp cloth, a damp cloth with Mopar威 Total Clean, then Mopar威 Spot & Stain Remover if absolutely necessary. Do not use harsh cleaners or Armorall. Use Mopar威 Total Clean to clean vinyl upholstery.
Leather Seat Care & Cleaning Mopar威 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 Mopar威 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.
MAINTAINING YOUR VEHICLE 391
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.
392 MAINTAINING YOUR VEHICLE
Glass Surfaces All glass surfaces should be cleaned on a regular basis with Mopar威 Glass Cleaner or any commercial household-type glass cleaner. Never use an abrasive type cleaner. Use caution when cleaning inside rear windows equipped with electric defrosters. Do not use scrapers or other sharp instruments which may scratch the elements. When cleaning the rear view mirror, spray cleaner on the towel or rag that you are using. Do not spray cleaner directly on the mirror. Cleaning Plastic Instrument Cluster Lenses The lenses in front of the instruments in this vehicle are molded in clear plastic. When cleaning the lenses, care must be taken to avoid scratching the plastic. 1. Clean with a wet soft rag. A mild soap solution may be used, but do not use high alcohol content or abrasive cleaners. If soap is used, wipe clean with a clean damp rag.
2. Dry with a soft tissue. Seat Belt Maintenance Do not bleach, dye or clean the belts with chemical solvents or abrasive cleaners. This will weaken the fabric. Sun damage will also weaken the fabric. If the belts need cleaning, use Mopar威 Total Clean, a mild soap solution, or lukewarm water. Do not remove the belts from the vehicle to wash them. Replace the belts if they appear frayed or worn or if the buckles do not work properly. Dry with a soft tissue.
