WARNING! (Continued)• Do not allow petroleum based fluid to contami-
nate the brake fluid. Brake seal components could
be damaged, causing partial or complete brake
failure. This could result in an accident.
Rear Axle And 4x4 Front Driving Axle Fluid Level
For models with 9.25 in Front Axles and 11.5 in Rear
Axles, refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information. For
normal service, periodic fluid level checks are not re-
quired. When the vehicle is serviced for other reasons, the
exterior surfaces of the axle assembly should be inspected.
When checking the fluid level (4500/5500 only), the
vehicle should be in a level position. The fluid level
should be 1/4 in ± 1/4 in (6.4 mm ± 6.4 mm) below the
fill hole on the front axle. The fluid level should be level
with the bottom of the fill hole on the rear axle. Drain And Refill
On 4500/5500 vehicles, remove the lower bolt to drain
the axle fluid.
Refer to “Maintenance Schedule” for the proper mainte-
nance intervals. 1 — 4500/5500 Rear Axle Fluid Fill Plug

Lubricant Selection
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
NOTE: The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Limited-Slip Differentials DO NOT REQUIRE any
limited slip oil additive (friction modifiers).
NOTE: Slight noise and mild shuddering may be evident
while turning a vehicle with limited slip differential on
concrete or dry pavement. These conditions should be
considered normal operation of the limited slip differential. Transfer Case
Drain and Refill
Refer to “Maintenance Schedule” for proper maintenance
intervals.

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 the manufacturer ’s recommended trans-
mission fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion. It is important that the transmission fluid be main-
tained at the prescribed level using the recommended
fluid.
CAUTION!• Do not use chemical flushes in your transmission
as the chemicals can damage your transmission
components. Such damage is not covered by the
New Vehicle Limited Warranty.
(Continued) CAUTION! (Continued)• Using a transmission fluid other than the manu-
facturer’s recommended fluid may cause deterio-
ration 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 Genu-
ine Parts” in “Maintaining Your Vehicle” for fur-
ther information.
Fluid Level Check
If equipped with a dipstick, use the following procedure.
If your vehicle has a capped dipstick tube, it is sealed and
should not be tampered with. Your authorized dealer has
the proper tools to ensure that the fluid level is set
properly. The fluid level should be checked when the
engine is fully warmed up and the fluid in the transmis-
sion is at normal operating temperature. Operation of the402 MAINTAINING YOUR VEHICLE

transmission with an improper fluid level will greatly
reduce the life of the transmission and of the fluid. Check
the fluid level whenever the vehicle is serviced.
Fluid Level Check – 545RFE
Check the fluid level while the transmission is at normal
operating temperature 82°C (180°F). This occurs after at
least 15 miles (25 km) of driving. At normal operating
temperature the fluid cannot be held comfortably be-
tween 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 shift lever momentarily into each gear posi-
tion ending with the lever in PARK.
5. Remove the dipstick, wipe it clean and reinsert it until
seated.
6. Remove the dipstick again and note the fluid level on
both sides. The fluid level should be between the “HOT”
(upper) reference holes on the dipstick at normal operat-
ing temperature. Verify that 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 minutes for the oil to fully drain into
the transmission before rechecking the fluid level.
NOTE: If it is necessary to check the transmission below
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
7 MAINTAINING YOUR VEHICLE 403

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. Automatic Transmission Fluid and Filter Change
Refer to “Maintenance Schedule” for the proper mainte-
nance intervals.
NOTE: If the transmission is disassembled for any
reason, the fluid and filter(s) should be changed.
It is important that proper lubricant is used in the trans-
mission. Refer to “Fluids, Lubricants, and Genuine Parts”
in “Maintaining Your Vehicle” for further information.
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.404 MAINTAINING YOUR VEHICLE

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 affect 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 seacoast localities.
• Atmospheric fallout/industrial pollutants.
Washing
• Wash your vehicle regularly. Always wash your ve-
hicle in the shade using MOPAR  Car Wash or equiva-
lent, 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  Super Kleen Bug
and Tar Remover or equivalent to remove.
7 MAINTAINING YOUR VEHICLE 405

• Use a high quality cleaner wax, such as MOPAR 
Cleaner Wax or equivalent to remove road film, stains
and to protect your paint finish. Take care never to
scratch the paint.
• Avoid using abrasive compounds and power buffing
that may diminish the gloss or thin out the paint
finish.
CAUTION!• Do not use abrasive or strong cleaning materials
such as steel wool or scouring powder which will
scratch metal and painted surfaces.
• 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 trunk 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 pos-
sible. The cost of such repairs is considered the respon-
sibility of the owner.406 MAINTAINING YOUR VEHICLE

• If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., be sure 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.
• Use MOPAR  Touch Up Paint or equivalent on
scratches as soon as possible. Your authorized dealer
has touch up paint to match the color of your vehicle.
Wheel and Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome-plated wheels should be cleaned regularly with a
mild soap and water to prevent corrosion. To remove
heavy soil and/or excessive brake dust, use MOPAR 
Wheel Cleaner or equivalent or select a nonabrasive,
non-acidic cleaner. Do not use scouring pads, steel wool,
a bristle brush, or metal polishes. Only MOPAR  or
equivalent is recommended. Do not use oven cleaner. Avoid automatic car washes that use acidic solutions or
harsh brushes that may damage the wheels’ protective
finish.
Stain Repel Fabric Cleaning Procedure –
If Equipped
Stain Repel seats may be cleaned in the following man-
ner:
• Remove as much of the stain as possible by blotting
with a clean, dry towel.
• Blot any remaining stain with a clean, damp towel.
• For tough stains, apply MOPAR  Total Clean or
equivalent, or a mild soap solution to a clean, damp
cloth and remove stain. Use a fresh, damp towel to
remove soap residue.
