CAUTION!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 the
vehicle.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you. WARNING!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 indicate severe
and abnormal catalyst overheating. If this occurs, the
vehicle should be stopped, the engine shut OFF and the
vehicle allowed to cool. Thereafter, service, including a
tune-up to manufacturer’s specifications, should be ob-
tained immediately.

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 are 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 the battery is in
the vehicle, disconnect both vehicle battery cables
before connecting the charger to the 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. CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condi-
tioning components. Such damage is not covered by
the New Vehicle Limited Warranty.
446 MAINTAINING YOUR VEHICLE

WARNING!
Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer to
Section 3 of the Warranty Information book for
further warranty information.
The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced repairman.
Refrigerant Recovery and Recycling
R-134a air conditioning refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by an authorized dealer, or other
authorized service facility, using recovery and recycling
equipment.
NOTE: Use only manufacturer-approved A/C System
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oil, or Refrigerants.

CAUTION!The A/C air filter is labeled with an arrow to indicate
airflow direction through the filter. Failure to prop-
erly install the filter will result in the need to replace
it more often.
7. Rotate the glove compartment door back into position.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, sliding doors and hood hinges, should be lubri-
cated periodically with a lithium-based grease such as
MOPARt Spray White Lube to assure quiet, easy opera-
tion 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 compo-
nents to ensure 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
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild nonabrasive cleaner. This will remove accumula-
tions 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.

rules for your community. To prevent ingestion by ani-
mals or children, do not store ethylene glycol-based
engine coolant (antifreeze) 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 immediately.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine cold, the level of the engine coolant (antifreeze) in
the coolant recovery bottle should be between the ranges
indicated on the bottle.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
engine coolant (antifreeze) freeze point or replacing the
engine coolant (antifreeze). Advise your service atten-
dant of this. As long as the engine operating temperature
is satisfactory, the coolant bottle only needs to be checked
once a month.When additional engine coolant (antifreeze) is needed to
maintain 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 (a
few kilometers) of operation, you may observe vapor
coming from the front of the engine compartment. This is
normally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) to enter the radiator.
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 the engine coolant (antifreeze) freeze point in
the radiator and in the coolant recovery bottle. If

Master Cylinder — Brake Fluid Level CheckThe fluid level in the master cylinder should be checked
when performing underhood services, or immediately if
the “Brake System Warning Light” indicates system
failure.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the top of the
“FULL” mark on the side of the master cylinder reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the level up to the require-
ments 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. Re-
fer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type. WARNING!

Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Use of a brake fluid that has a lower initial boiling
point than the recommended MOPARt DOT 3
product or a brake fluid that is unidentified as to
FMVSS specification may result in sudden brake
failure during hard prolonged braking. You could
have an accident.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter or
moisture.
MAINTAINING YOUR VEHICLE 457 7

CAUTION!Do not allow petroleum based fluid to contaminate
the brake fluid — all brake seal components could be
damaged, causing partial or complete brake failure.
Automatic Transaxle
The automatic transaxle and differential assembly are
contained within a single housing.
The fluid level in the automatic transaxle should be
checked whenever the vehicle is serviced. Operation with
an improper fluid level will greatly reduce the life of the
transaxle and the fluid.
All four–speed transaxles are equipped with a conven-
tional filler tube and dipstick. If fluid is added, it should
be added through the filler tube.
All six–speed transaxles are equipped with a capped
dipstick tube. It is sealed and should not be tampered
with. Your authorized dealer has the necessary tools to
ensure that the fluid level is set properly.
Selection of Lubricant
It is important that the proper lubricant is used in the
transaxle to assure optimum transaxle performance. Use
only the manufacturer’s recommended transmission
fluid. Refer to “Fluids, Lubricants and Genuine Parts” in
this section for the correct fluid type. It is important that
the transmission fluid be maintained at the prescribed
level using the recommended fluid. No chemical flushes
should be used in any transaxle; only the approved
lubricant may be used.
458 MAINTAINING YOUR VEHICLE

CAUTION!Using a transmission fluid other than the manufac-
turer’s recommended fluid may cause deterioration
in transaxle 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” in this sec-
tion for the correct fluid type.
Fluid Level Check — 3.8L and 4.0L Engines with
Six-Speed Automatic Transaxle — If Equipped
The six-speed automatic transaxle is a sealed unit and has
no dipstick. See your authorized dealer to have the
transaxle fluid checked or serviced.
Fluid Level Check — 3.3L Engine with Four-Speed
Automatic Transaxle — If Equipped
The dipstick is located just behind the radiator on the
lower right side.
To properly check the automatic transaxle fluid level, the
following procedure must be used:
1. The vehicle must be on level ground.
2. The engine should be running at curb idle speed for a
minimum of 60 seconds.
3. Fully apply the parking brake.
4. Place the shift lever momentarily into each gear posi-
tion, ending with the shift lever in PARK. Wipe the area
around the dipstick clean to eliminate the possibility of
dirt entering the transaxle.
