Materials Added to Engine Oils
The manufacture strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and
it's performance may be impaired by supplemental ad-
ditives.
Disposing of Used Engine Oil and Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station, or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area. ENGINE OIL FILTER
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
All of this manufacturer's engines have a full-flow type
disposable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consider-
ably. Only high quality filters should be used to assure
most efficient service. Mopar t Engine Oil Filters are high
quality oil filters and are recommended.
DRIVE BELT
At the mileage indicated in section 8: ªMaintenance
Scheduleº, replace the drive belt with a new drive belt.
NOTE: The belt must be routed correctly to ensure
proper drive function.378 MAINTAINING YOUR VEHICLE

SPARK PLUGS
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Refer to ªFluids, Lubricants, and Genuine Partsº in
this section for the proper type of spark plug for use in
your vehicle.
ENGINE AIR CLEANER FILTER
Refer to the ªMaintenance Scheduleº in Section 8 of this
manual for engine air cleaner filter maintenance inter-
vals.
NOTE: Be sure to follow the ªdusty or off-road condi-
tionsº maintenance interval if applicable. WARNING!The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the
vehicle with the air induction system (air cleaner,
hoses, etc.) removed. Failure to do so can result in
serious personal injury.
CATALYTIC CONVERTER
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device. MAINTAINING YOUR VEHICLE 379
7

Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
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 suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine, and allow it to cool.
Service, including a tune up to manufacturer's specifica-
tions, should be obtained immediately.380 MAINTAINING YOUR VEHICLE

To minimize the possibility of catalyst damage:
² Do not shut off the engine or interrupt the ignition
when the transaxle is in gear and the vehicle is in
motion.
² Do not try to start the engine by pushing or towing the
vehicle.
² Do not idle the engine with any ignition coil connec-
tors disconnected for prolonged periods.
MAINTENANCE-FREE BATTERY
You will never have to add water, nor is periodic main-
tenance required.
NOTE: The battery is stored in a compartment behind
the left front fender and is accessible without removing
the tire and wheel. Remote battery terminals are located
in the engine compartment for jump-starting.
To access the battery, turn the steering wheel fully to the
right and remove the inner fender shield. WARNING!² Battery fluid is a corrosive acid solution and can
burn or even blind you. Don't allow battery fluid
to contact your eyes, skin, or clothing. Don't lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water.
² Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Don't use a
booster battery or any other booster source with an
output greater than 12 volts. Don't allow cable
clamps to touch each other.
² Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands
after handling. MAINTAINING YOUR VEHICLE 381

CAUTION!The A/C Air Filter is labeled with an arrow to
indicate airflow direction through the filter. Failure
to install the filter properly will result in the need to
replace it more often.
7. Reinstall the glove box door dampener and glove box.
POWER STEERING
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 ensure 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 ªFluids, Lubricants, and Genuine
Partsº in this section for the correct fluid type.
FRONT SUSPENSION
There are two front suspension lower ball joints that are
permanently lubricated. Inspect these ball joints when
other maintenance is performed. A damaged seal and the
corresponding potentially damaged ball joint must be
replaced. MAINTAINING YOUR VEHICLE 385

Keep the blade rubber out of contact with petroleum
products such as engine oil, gasoline, etc.
NOTE: Always refer to the wiper blade packaging for
specific installation instructions. Many wiper blade re-
placements fit multiple vehicles.
WINDSHIELD WASHERS
NOTE: Refer to the appropriate ªEngine Compartmentº
diagram in Section 7 for the location of the windshield
washer fluid reservoir.
The fluid reservoir for the windshield washers is located
in the engine compartment. Be sure to check the fluid
level in the reservoir at regular intervals. Fill the reservoir
with windshield washer solvent (not radiator antifreeze)
and operate the system for a few seconds to flush out the
residual water. WARNING!Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.
EXHAUST SYSTEM
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system
or if exhaust fumes can be detected inside the vehicle or
when the underside or rear of the vehicle is damaged,
have a competent technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep MAINTAINING YOUR VEHICLE 387

Coolant Checks
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed, and refilled with
fresh coolant. 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 rub-
ber, cracking, tears, cuts, and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks. Cooling System Ð Drain, Flush, and Refill
The system should be drained, flushed, and refilled at the
intervals shown in the ªMaintenance Scheduleº in Sec-
tion 8 of this manual.
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 manufacturer's recommended coolant, refer
to ªFluids, Lubricants, and Genuine Partsº for correct
coolant type. MAINTAINING YOUR VEHICLE 389
7

CAUTION!² Mixing of coolants other than specified HOAT
engine coolants, may result in engine damage and
may decrease corrosion protection. If a non-HOAT
coolant is introduced into the cooling system in an
emergency, it should be replaced with the speci-
fied coolant as soon as possible.
² 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.
² This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propy-
lene Glycol based coolants is not recommended. Adding Coolant
Your vehicle has been built with an improved engine
coolant that allows extended maintenance intervals. This
coolant can be used up to 5 Years or 100,000 mi (160 000
km) before replacement. To prevent reducing this ex-
tended maintenance period, it is important that you use
the same coolant throughout the life of your vehicle.
Please review these recommendations for using Hybrid
Organic Additive Technology (HOAT) coolant.
When adding coolant:
² The manufacturer recommends using Mopar t
Antifreeze/Coolant 5 Year/100,000 Mile Formula
HOAT (Hybrid Organic Additive Technology).
² Mix a minimum solution of 50% HOAT engine coolant
and distilled water. Use higher concentrations (not to
exceed 70%) if temperatures below 2 34F( 2 37 C) are
anticipated.390 MAINTAINING YOUR VEHICLE
