Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Materials Added to Engine Oil
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 its
performance may be impaired by supplemental addi-
tives.
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, servicestation, 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
The manufacturer's engines have a full-flow type oil
filter. Use a filter of this type for replacement. The quality
of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient
service. MopartEngine Oil Filters are a high quality oil
filter and are recommended.

DRIVE BELT
At the mileage indicated in the maintenance schedule,
replace the drive belt with a new drive belt.
NOTE:The drive belt must be routed correctly to ensure
proper drive function.
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. Malfunctioning spark plugs can damage the cata-
lytic converter. For proper type of replacement spark
plugs, refer to Fluids, Lubricants and Genuine Parts for
correct spark plug type.
ENGINE AIR CLEANER
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.

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 an
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.
A/C Air Filter Ð If Equipped
Refer to the ªMaintenance Scheduleº in Section 8 of this
manual for A/C Air Filter service intervals.

indicate airflow direction through the filter. Failure
to properly install the filter will result in the need to
replace it more often.

452 MAINTAINING YOUR VEHICLE

If the fluid level indicates low, add sufficient fluid to
bring to the proper level.
CAUTION!
Do not overfill. Dirt and water in the transaxle can
cause serious damage. To prevent dirt and water from
entering the transaxle after checking or replenishing
fluid, make certain that the dipstick cap is reseated
properly.
Fluid and Filter Changes
Refer to the ªMaintenance Scheduleº in Section 8 of this
manual for the recommended transaxle fluid and filter
change intervals.
If the transaxle is disassembled for any reason, the fluid
and filter should be changed.
Special Additives
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transaxle. The only exception to this policy is
the use of special dyes to aid in detecting fluid leaks. In
addition, avoid using transaxle sealers as they may
adversely affect seals.
FRONT AND REAR WHEEL BEARINGS
Front and rear wheel bearings are permanently sealed.
No regular maintenance is required for these compo-
nents.
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
