CAUTION!
The A/C air filter is identified with an arrow to
indicate airflow direction through the filter. Failure
to properly install the filter will result in the need to
replace it more often.

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
MOPAR Spray White Lube or equivalent, 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 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 MOPAR
Lock Cylinder Lubricant or equivalent 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.

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
engine coolant (antifreeze) needs to be added, contents
of the coolant recovery bottle must also be protected
against freezing.
•If frequent engine coolant (antifreeze) additions are
required, or if the level in the coolant recovery bottle
does not drop when the engine cools, the cooling
system should be pressure tested for leaks.

Master Cylinder – Brake Fluid Level Check
The 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 “Main-
taining Your Vehicle” for further information.
WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also identified on the
original factory installed hydraulic master cylin-
der reservoir.

WARNING! (Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep the
master cylinder reservoir cap secured at all times.
Brake fluid in a open container absorbs moisture
from the air resulting in a lower boiling point.
This may cause it to boil unexpectedly during hard
or prolonged braking, resulting in sudden brake
failure. This could result in a collision.
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.(Continued)
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 a collision.
Automatic Transmission
The automatic transmission and differential assembly are
contained within a single housing.
The fluid level in the automatic transmission should be
checked whenever the vehicle is serviced. Operation with
an improper fluid level will greatly reduce the life of the
transmission and the fluid.
The six–speed transmission is 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.

MAINTAINING YOUR VEHICLE 569

CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check
The six-speed automatic transmission is a sealed unit and
has no dipstick. See your authorized dealer to have the
transmission fluid checked or serviced.
Fluid And Filter Changes
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
If the transmission is disassembled for any reason, the
fluid and filter should be changed.
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.

steering column. If you experience temporary or perma-
nent loss of these systems, see your authorized dealer for
service.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than
21 days, you may want to take steps to protect your
battery. You may do the following:
•Remove the 20 Amp mini-fuse in the Totally Inte-
grated Power Module (TIPM) labeled Ignition-Off
Draw (IOD).
•Or, disconnect the negative cable from the battery.
•Anytime you store your vehicle, or keep it out of
service for two weeks or more, run the air conditioning
system at idle for about five minutes in the fresh air
and high blower setting. This will ensure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
