490 SERVICING AND MAINTENANCE
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 five minutes after
a fully warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always main-
tain the oil level within the SAFE zone on the dipstick.
Adding one quart of oil when the reading is at the bottom of
the SAFE zone will result in a reading at the top of the safe
zone on these engines.
Adding Washer Fluid
The fluid reservoir is located under the hood and should be
checked for fluid level at regular intervals. Fill the reservoir
with windshield washer solvent only (not radiator anti -
freeze). When refilling the washer fluid reservoir, take some
washer fluid and apply it to a cloth or towel and wipe the
wiper blades clean. 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.
After the engine has warmed up, operate the defroster for a
few minutes to reduce the possibility of smearing or freezing
the fluid on the cold windshield. Windshield washer solu-
tion used with water as directed on the container, aids
cleaning action, reduces the freezing point to avoid line clog
-
ging, and is not harmful to paint or trim.
CAUTION!
Overfilling or underfilling will cause oil aeration or loss
of oil pressure. This could damage your engine.
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.

SERVICING AND MAINTENANCE 515
Rear Axle And 4x4 Front Driving Axle Fluid Level
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons the
exterior surfaces of the axle assembly should be inspected. If
gear oil leakage is suspected inspect the fluid level. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information. This inspection should be made with
the vehicle in a level position.
The fluid level should be even with the bottom of the fill hole
(within 1/4 in (6.4 mm) of edge of hole) for the front axle and
rear axle.
Lubricant Selection
Refer to “Fluids And Lubricants” in “Technical Specifica-
tion” 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
Rear axles equipped with a Limited Slip Differential require
that 5 oz. (148 ml) Mopar Limited Slip Additive be added to
the gear lubricant. Refer to “Fluids And Lubricants” in
“Technical Specification” for further information. The
Mopar Limited Slip Additive should be added to the gear
lubricant whenever a fluid change is made to an axle
equipped with a Limited Slip Differential.
NOTE:
When refilling a limited slip differential axle which requires
a friction modification additive, the additive should be
added before the gear lubricant to ensure proper additive
fill.
Drain And Refill
Refer to the “Maintenance Plan” for the proper maintenance
intervals.
Transfer Case
Selection Of Lubricant
Use only the manufacturer's recommended fluid. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information.

544 SERVICING AND MAINTENANCE
• For grease stains, apply Mopar Multi-Purpose Cleaner to aclean, damp cloth and remove stain. Use a fresh, damp
towel to remove soap residue.
• Do not use any harsh solvents or any other form of protectants on Stain Repel products.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical solvents
or abrasive cleaners. This will weaken the fabric. Sun
damage can also weaken the fabric.
If the belts need cleaning, use a mild soap solution or luke -
warm water. Do not remove the belts from the vehicle to
wash them. Dry with a soft cloth.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
NOTE:
If the belts retract slowly, inspect the upper turning loop for
soiling. If soiling is present, clean with a wet soft cloth until
all residue is removed.
Plastic And Coated Parts
Use Mopar Total Clean to clean vinyl upholstery.
WARNING!
A frayed or torn belt could rip apart in a collision and
leave you with no protection. Inspect the belt system
periodically, checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately. Do not
disassemble or modify the system. Seat belt assemblies
must be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing, etc.).
CAUTION!
• Direct contact of air fresheners, insect repellents, suntan lotions, or hand sanitizers to the plastic,
painted, or decorated surfaces of the interior may cause
permanent damage. Wipe away immediately.
• Damage caused by these type of products may not be covered by your New Vehicle Limited Warranty.
