314SERVICING AND MAINTENANCE
Air Conditioning Filter Replacement (A/C
Air Filter)
Refer to “Scheduled Servicing” in this section
for the proper maintenance intervals.
The A/C air filter is located in the fresh air inlet
behind the glove compartment. Perform the
following procedure to replace the filter:

1. Open the glove compartment and remove
all contents.
Glove Compartment

2. There are glove compartment travel stops on both sides of the glove compartment
door, partially close the glove compartment
door and push inward to release the glove
compartment travel stop on one side and
repeat this procedure for the opposite side.
3. Pull the right hand side of the glove compartment door toward the rear of the
vehicle to disengage the glove
compartment door from its hinges. NOTE:
When disengaging the glove compartment door
from its hinges, there will be some resistance.
4. With the glove compartment door loose,
remove the glove compartment tension
tether and tether clip by sliding the clip
toward the face of the glove compartment
door and lifting the clip out of glove
compartment door.

Right Side Of Glove Compartment

WARNING!
Do not remove the cabin air filter while the
vehicle is running, or while the ignition is in
the ACC or ON/RUN mode. With the cabin air
filter removed and the blower operating, the
blower can contact hands and may propel dirt
and debris into your eyes, resulting in
personal injury.

324SERVICING AND MAINTENANCE
The radiator normally remains completely full,
so there is no need to remove the radiator/
coolant pressure cap unless checking for
engine coolant (antifreeze) freeze point or
replacing coolant. Advise your service attendant
of this. As long as the engine operating
temperature is satisfactory, the coolant bottle
need only be checked once a month.
When additional engine coolant (antifreeze) is
needed to maintain the proper level, only OAT
coolant that meets the requirements of FCA
Material Standard MS.90032 should be added
to the coolant bottle. Do not overfill.
Coolant Level
The coolant expansion bottle provides a quick
visual method for determining that the coolant
level is adequate. With the engine off and cold,
the level of the coolant (antifreeze) in the bottle
should be between the “MAX” and “MIN” lines
marked on the bottle.
As long as the engine operating temperature is
satisfactory, the coolant bottle need only be
checked once a month.
When additional coolant (antifreeze) is needed
to maintain the proper level, it should be added
to the coolant bottle. Do not overfill. See an authorized dealer for service.
Points To Remember
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor
coming from the front of the engine compart
-
ment. This is normally a result of moisture from
rain, snow, or high humidity accumulating on
the radiator and being vaporized when the ther -
mostat opens, allowing hot engine coolant (anti -
freeze) 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 expansion bottle.
Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant (antifreeze) needs to be added, the
contents of the coolant expansion bottle
must also be protected against freezing.
If frequent engine coolant (antifreeze) addi-
tions are required, the cooling system should
be pressure tested for leaks.
Maintain engine coolant (antifreeze) concen -
tration at a minimum of 50% OAT coolant
(conforming to MS.90032) and distilled
water for proper corrosion protection of your
engine which contains aluminum compo -
nents.
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever
necessary, install ONLY the correct type ther -
mostat. Other designs may result in unsatis -
factory engine coolant (antifreeze)
performance, poor gas mileage, and
increased emissions.

346SERVICING AND MAINTENANCE
STORING THE VEHICLE
If you are storing your vehicle for more than
21 days, we recommend that you take the
following steps to minimize the drain on your
vehicle's battery:
Disconnect the negative cable from battery.
Any time you store your vehicle or keep it out
of service (i.e., vacation) 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 compressor damage when the
system is started again.
BODYWORK
PROTECTION FROM ATMOSPHERIC
A
GENTS
Vehicle body care requirements vary according
to geographic 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
underbody 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
BODY AND UNDERBODY MAINTENANCE
Cleaning Headlights
Your vehicle is equipped with plastic headlights
and fog lights that are lighter and less
susceptible to stone breakage than glass
headlights.
Plastic is not as scratch resistant as glass and
therefore different lens cleaning procedures
must be followed.
To minimize the possibility of scratching the
lenses and reducing light output, avoid wiping
with a dry cloth. To remove road dirt, wash with
a mild soap solution followed by rinsing.
Do not use abrasive cleaning components,
solvents, steel wool or other aggressive
material to clean the lenses.
