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.
7. Rotate the glove compartment door back
into position.
Body LubricationLocks and all body pivot points, including such
items as seat tracks, door hinge pivot points
and rollers, liftgate, tailgate, decklid, sliding
doors and hood hinges, should be lubricated
periodically with a lithium based grease, such
as MOPAR Spray White Lube 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 at-
tention should also be given to hood latching
components to ensure proper function. When
performing other underhood services, the hoodlatch, 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 di-
rectly into the lock cylinder.
Windshield Wiper BladesClean 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 accumulations 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 wind-
shield.
Avoid using the wiper blades to remove frost or
ice from the windshield. Keep the blade rubber
out of contact with petroleum products such as
engine oil, gasoline, etc.NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and fre-
quency of use. Poor performance of blades
may be present with chattering, marks, wa-
ter lines or wet spots. If any of these condi-
tions are present, clean the wiper blades or
replace as necessary.Adding Washer FluidThe washer fluid reservoir is located in the
engine compartment, and the fluid level should
be checked at regular intervals. Fill the reservoir
with windshield washer solvent only (not radia-
tor antifreeze).
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, 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 cli-
mate. This rating information can be found on
most washer fluid containers.

NOTE:
Intentional tampering with emissions con-
trol systems can result in civil penalties
being assessed against you.
In unusual situations involving grossly malfunc-
tioning engine operation, a scorching odor may
suggest severe and abnormal catalyst over-
heating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, includ-
ing a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter
damage:
•Do not shut off the engine or interrupt the
ignition, when the transmission is in gear and
the vehicle is in motion.
•Do not try to start the engine by pushing or
towing the vehicle.
•Do not idle the engine with any spark plug
wires disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunction-
ing operating conditions.Cooling System
WARNING!
•When working near the radiator cooling
fan, disconnect the fan motor lead or turn
the ignition switch to the OFF position. The
fan is temperature controlled and can start
at any time the ignition switch is in the ON
position.
•You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator is hot.
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine cool-
ant (antifreeze) is dirty or rusty in appearance,
the system should be drained, flushed, and
refilled with fresh engine coolant (antifreeze).Check the front of the A/C condenser for any
accumulation of bugs, leaves, etc. If dirty, clean
by gently spraying water from a garden hose
vertically down the face of the condenser.
Check the coolant recovery bottle tubing for
brittle rubber, cracking, tears, cuts, and tight-
ness of the connection at the bottle and radiator.
Inspect the entire system for leaks.
Cooling System – Drain, Flush, And Refill
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
If the engine coolant (antifreeze) is dirty or
contains a considerable amount of sediment,
clean and flush with a reliable cooling system
cleaner. Follow with a thorough rinsing to re-
move all deposits and chemicals. Properly dis-
pose of old engine coolant (antifreeze).
Selection Of Coolant
Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
263

The cap should be inspected and cleaned if
there is any accumulation of foreign material on
the sealing surfaces.
WARNING!
•The warning words “DO NOT OPEN HOT”
on the cooling system pressure cap are a
safety precaution. Never add engine cool-
ant (antifreeze) when the engine is over-
heated. Do not loosen or remove the cap
to cool an overheated engine. Heat causes
pressure to build up in the cooling system.
To prevent scalding or injury, do not re-
move the pressure cap while the system is
hot or under pressure.
•Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (an-
tifreeze) is a regulated substance requiring
proper disposal. Check with your local authori-
ties to determine the disposal rules for yourcommunity. To prevent ingestion by animals 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 or pet, seek emergency
assistance 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 idling and warm to
normal operating temperature, the level of the
engine coolant (antifreeze) in the bottle should
be between the “ADD” and “FULL” lines shown
on the bottle.
The radiator normally remains completely full,
so there is no need to remove the radiator cap
unless checking for the coolant freeze point or
replacing the engine coolant (antifreeze). Ad-
vise your service attendant of this. As long as
the engine operating temperature is satisfac-
tory, the coolant bottle need only 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/kilometers of operation, you may ob-
serve vapor coming from the front of the
engine compartment. This is normally a re-
sult of moisture from rain, snow, or high
humidity accumulating on the radiator and
being vaporized 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 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.
265

•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 components.
•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 nec-
essary, install ONLY the correct type thermo-
stat. Other designs may result in unsatisfac-
tory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake SystemIn order to assure brake system performance,
all brake system components should be in-spected periodically. Refer to the “Maintenance
Schedule” for the proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal can
result in abnormally high brake tempera-
tures, excessive lining wear, and possible
brake damage. You would not have your full
braking capacity in an emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be
checked when performing under hood services,
or immediately if the brake system warning light
is on.
Be sure to clean the top of the master cylinder
area before removing the cap. If necessary, add
fluid to bring the fluid level up to the require-
ments described on the brake fluid reservoir.
Fluid level can be expected to fall as the brake
pads wear. The brake fluid level should be
checked when the pads are replaced. However,low fluid level may be caused by a leak and a
checkup may be needed.
NOTE:
If your vehicle is equipped with a manual
transmission, the brake fluid reservoir sup-
plies fluid to both the brake system and the
clutch release system. The two systems are
separated in the reservoir, and a leak in one
system will not affect the other system. The
manual transmission clutch release system
should not require fluid replacement during
the life of the vehicle. If the brake fluid
reservoir is low and the brake system does
not indicate any leaks or other problems, it
may be a result of a leak in the hydraulic
clutch release system. See your local autho-
rized dealer for service.
Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
266

MAINTENANCE SCHEDULE
Maintenance Schedule — Gasoline
Engine
The Scheduled Maintenance services listed in
this manual must be done at the times or
mileages specified to protect your vehicle war-
ranty and ensure the best vehicle performance
and reliability. More frequent maintenance may
be needed for vehicles in severe operating
conditions, such as dusty areas and very short
trip driving. Inspection and service should also
be done anytime a malfunction is suspected.
The oil change indicator system will remind you
that it is time to take your vehicle in for sched-
uled maintenance.
On Non-EVIC equipped vehicles, “CHANgE
OIL” will flash in the instrument cluster odom-
eter and a single chime will sound, indicating
that an oil change is necessary.
The oil change indicator message will illuminate
approximately 7,000 miles (11,200 km) after the
most recent oil change was performed. Have
your vehicle serviced as soon as possible,
within 500 miles (800 km). However, an earlieroil change at 4,500 miles (7,500 km) may be
required if the vehicle is operated under “Se-
vere Duty Conditions” later in this section.
NOTE:
•The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicle’s oil if it has been 12
months since your last oil change even if
the oil change indicator message is NOT
illuminated.
•Change your engine oil more often if you
drive your vehicle off-road for an ex-
tended period of time.
•Under no circumstances should oil
change intervals exceed 7,500 miles
(12,000 km) or 12 months, whichever
comes first.
Your dealer will reset the oil change indicator
message after completing the scheduled oil
change. If this scheduled oil change is per-
formed by someone other than your dealer, the
message can be reset by referring to the steps
described under “Instrument ClusterDescription/Odometer/Trip Odometer” in “Un-
derstanding Your Instrument Panel” for further
information.
Once A Month Or Before A Long Trip
•Check the engine oil level about five minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
•Check the windshield washer solvent and
add if required.
•Check tire pressure and look for unusual
wear or damage. Rotate tires at the first sign
of irregular wear, even if it occurs before the
oil indicator system turns on.
•Inspect the battery and clean and tighten the
terminals as required.
•Check the fluid levels of coolant reservoir,
automatic transmission, brake master cylin-
der and power steering and fill as needed.
•Check all lights and other electrical items for
correct operation.
