Fuel Filter
The fuel filter is a part of the fuel module and it does not
require maintenance.
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.
Have your vehicle serviced promptly in the event of
engine malfunction, particularly when involving en-
gine misfire or other apparent loss of performance.
Continued 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.
204 MAINTAINING YOUR VEHICLE

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 in 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 indicate severe
and abnormal catalyst overheating. If this should occur,
safely bring the vehicle to a complete stop, shut the
engine off, and allow the vehicle to cool. Thereafter,
obtain service, including a tune-up to manufacturer's
specifications immediately.
To minimize the possibility of catalytic converter damage:
²Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
²Do not try to start the engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.
Ignition Wiring System and Ignition Timing
The ignition cables should be kept clean and the termi-
nals fully seated. Do not remove the nipple assemblies
from the coil towers. Cracked, damaged, or faulty cables
should be replaced. See your authorized dealer for ser-
vice.

NOTE:
²Because of the plastic body shell on your vehicle,
ignition cables should be replaced with the specially
designed RFI cables available at your dealer.
²The ignition timing cannot be set on this engine.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from plugging due to deposits. As vehicle mileage builds
up, the Crankcase Ventilation Valve orifice may accumu-
late deposits. If a valve is not working properly, it should
be replaced with a new orifice. DO NOT ATTEMPT TO
CLEAN THE OLD ORIFICE!
Check the ventilation hose for indication of damage or
plugging deposits and replace if necessary. See your
authorized dealer for service.

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.
NOTE:If A/C performance seems less then normal,
check the front of the A/C condenser (located in front of
the radiator) for dirt and insect accumulation. Clean with
a gentle water spray as required. Front end fascia protec-
tors may reduce air flow to the condenser and radiator,
reducing A/C and engine cooling performance.WARNING!
²Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer to
Section 3 of the Warranty Information book for
further warranty information.
²The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced technician.

Lubrication
The tie rod ends are lubricated for life. No periodic
lubrication is required.
Body Lubrication
Locks and all body pivot points, including seat tracks,
doors hinges, trunk/liftgate hinges, and hood hinges,
should be lubricated periodically 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 attention should also be given to hood latching
components to insure proper function. When performing
other underhood services, the hood latch, release mecha-
nism, 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 smallamount of a high quality lubricant, such as MopartLock
Cylinder Lubricant or equivalent directly into the lock
cylinder.
Body Mechanism Lubrication
