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 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. MoparEngine Oil Filters are high
quality oil filters and are recommended.
Drive Belt
At the mileage indicated in section 8: “Maintenance
Schedule”, replace the drive belt with a new drive belt.
NOTE:The 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. Refer to “Fluids, Lubricants, and Genuine Parts” in
this section for the proper type of spark plug for use in
your vehicle.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” in Section 8 of this
manual for engine air cleaner filter maintenance inter-
vals.
NOTE:Be sure to follow the “dusty or off-road condi-
tions” 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.

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.

To minimize the possibility of catalyst damage:
•Do not shut off the engine or interrupt the ignition when
the transaxle 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 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!
•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.
•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.

CAUTION!
•It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to
the negative post. Battery posts are marked posi-
tive (+) and negative (-) and identified on the
battery case. Cable clamps should be tight on the
terminal posts and free of corrosion. Apply grease
to posts and clamps after tightening.
•If a “fast charger” is used while the battery is in
the vehicle, disconnect both vehicle battery cables
before connecting the charger to battery. Do not
use a “fast charger” to provide starting voltage as
battery damage can result.
Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an Authorized Dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a performance
test. Drive belt tension should also be checked at this
time.
