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 posi-
tive (+) and negative (-) and identified on the
battery case. Cable clamps should be tight on the
terminal posts and free of corrosion.
• If a “ fast charger ” is used while battery is in
vehicle, disconnect both vehicle battery cables
before 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 system
performance check. Drive belt tension should also be
checked at this time.388 MAINTAINING YOUR VEHICLE

frame with the direction of airflow (away from the
blower motor and towards the center of the car).
Refer to the “ Maintenance Schedules ” section of this
manual for the recommended air conditioning filter
replacement intervals.
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.  WARNING!Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering 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.
Front Suspension Ball Joints
The front suspension ball joints are permanently sealed.
No regular maintenance is required for these compo-
nents.390 MAINTAINING YOUR VEHICLE

Steering Shaft Seal
The steering shaft seal, at the point where the shaft passes
through the bulkhead, is lubricated when it is installed. If
the seal becomes noisy when the steering shaft is turned,
it should be lubricated with a multi-purpose grease.
Mopar multi-purpose lubricant is recommended.
Steering Linkage
The tie rod end ball joints are permanently lubricated and
do not require periodic maintenance.
Drive Shaft Universal Joints
Your vehicle has constant velocity universal joints. Peri-
odic lubrication of these joints is not required. However,
the joint boots should be inspected for external leakage or
damage when other maintenance is performed. If leakage
or damage is evident, the universal joint boot and grease
should be replaced immediately. Continued operation could result in failure of the univer-
sal joint due to water and dirt contamination of the
grease. This would require complete replacement of the
joint assembly.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, doors, liftgate, sliding doors and hood hinges,
should be lubricated periodically to assure quiet, easy
operation and to protect against rust and wear. Prior to
the application 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
components to insure proper function. When performing
other underhood services, the hood latch, release mecha-
nism and safety catch should be cleaned and lubricated. MAINTAINING YOUR VEHICLE 391

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 in the maintenance schedules, the
system should be drained, flushed and refilled.
If the solution is dirty or contains a considerable amount
of sediment, clean and flush with a reliable cooling
system cleaner. Follow with a thorough rinsing to remove
all deposits and chemicals. Properly dispose of old
antifreeze solution.
Selection Of Coolant
Use only the manufacturers recommended coolant, refer
to Recommended Fluids, Lubricants and Genuine Parts
for correct coolant type. CAUTION!• Mixing of coolants other than specified engine
coolant, may result in engine damage, and de-
crease corrosion protection. If a non-HOAT cool-
ant 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
engine coolant (antifreeze) products. Do not use
additional rust inhibitors or antirust products, as
they may not be compatible with the radiator
engine coolant and may plug the radiator.
• This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propy-
lene Glycol based coolants is not recommended. MAINTAINING YOUR VEHICLE 395

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 Hoses
When the vehicle is serviced for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, tears, cuts, abrasion, and excessive swelling
indicate deterioration of the rubber. Particular attention
should be made to examining those hose surfaces nearest
to high heat sources, such as the exhaust manifold. Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
NOTE: Often, fluid such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to facilitate the assembly of hoses to couplings.
Therefore, oil wetness at the hose-coupling area is not
necessarily an indication of leakage. Actual dripping of
hot fluid when systems are under pressure (during
vehicle operation), should be noted before hose is re-
placed based on leakage.
NOTE: Inspection of brake hoses should be performed
whenever the brake system is serviced and every engine
oil change. Inspect hydraulic brake hoses for surface
cracking, scuffing, or worn spots. If there is any evidence
of cracking, scuffing, or worn spots, the hose should be400 MAINTAINING YOUR VEHICLE

CAUTION!Do not overfill. Dirt and water in the transmission
can cause serious damage. To prevent dirt and water
from entering the transmission after checking or
replenishing fluid, make certain that the dipstick cap
is reseated properly.
Fluid and Filter Changes
Automatic transmission fluid should be changed on all
transmissions as follows:
Normal Usage — No change necessary
Severe Usage (fluid and filter) — Refer to Maintenance
Schedule “ B ”
Severe Usage is defined as: • Police, taxi, limousine, commercial type operation, or
trailer towing where the vehicle is driven regularly for
more than 45 minutes of continuous operation.
NOTE: Refer to Section 8 of this manual for Mainte-
nance Schedules.
If the transmission is disassembled for any reason, the
fluid and filter should be changed.
Special Additives
Do not add any fluid 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. MAINTAINING YOUR VEHICLE 405

Front And Rear Wheel Bearings
Front and rear wheel bearings are permanently sealed.
No regular maintenance is required for these compo-
nents.
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 seacoast localities.
• Atmospheric fallout/industrial pollutants.406 MAINTAINING YOUR VEHICLE

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 a mild soap solution or
lukewarm water. Do not remove the belts from the car to
wash them.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
Cleaning The Instrument Panel and Underseat
Cup Holders
Removal
Remove the ash receiver from the convenience tray if
there is a smoker ’ s package in your vehicle. With your
index finger, locate the stop tab located at the rear of the
convenience tray.410 MAINTAINING YOUR VEHICLE
