NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow schedule “B” of the
Maintenance Schedulessection of this manual.
If none of these apply to you, then change your engine oil
at every interval shown on scheduleAof theMainte-
nance Schedulessection of this manual.
NOTE:Under no circumstances should oil change
intervals exceed 6,000 miles (10 000 km) or 6 months
whichever comes first.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could dam-
age your engine.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, we only recommend en-
gine oils that are API Certified and meet the requirements
of DaimlerChrysler’s Material Standard MS-6395. Use
Mopar or an equivalent oil meeting the specification
MS-6395.

on how and where used oil 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 Engine Oil Filters are high
quality oil filters and are recommended.
Drive Belts – Check Condition and Tension
At the mileage shown in the maintenance schedules,
check all drive belts for condition and proper tension.
Improper belt tension can cause belt slippage and failure.
Inspect the drive belts for evidence of cuts, cracks, or
glazing and replace them if there is any sign of damage
which could result in belt failure. If adjustment is re-
quired, adjust the belts according to the specificationsand procedures shown in the Service Manual. See the
Consumer Assistance section for information on ordering
a Service Manual.
Special tools are required to properly measure tension
and to restore belt tension to factory specifications. Also,
check belt routing to make sure there is no interference
between the belts and other engine components.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the mileage specified in the appropriate main-
tenance chart. The entire set should be replaced if there is
any malfunction due to a faulty spark plug. Check the
specifications section for the proper type of spark plug
for use in your vehicle.
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.
178 MAINTAINING YOUR VEHICLE

Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to seek service to assure proper catalyst operation
and prevent possible catalyst damage. If the Malfunction
Indicator light is flashing, immediate service is required.
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.
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 ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing 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 manufacturers 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.

Engine Timing Belt
Replace the engine timing belt at the intervals described
in the appropriate maintenance schedule.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from sticking or plugging due to deposits. As vehicle
mileage builds up, the PCV valve and passages may
accumulate deposits. If a valve is not working properly,
replace it with a new valve. DO NOT ATTEMPT TO
CLEAN THE OLD PCV VALVE!
Check ventilation hose for indication of damage or
plugging deposits. Replace if necessary.
Fuel Filter
A plugged fuel filter can cause hard starting or limit the
speed at which a vehicle can be driven. Should an
excessive amount of dirt accumulate in the fuel tank,
frequent replacement of the fuel filter which is mounted
in the fuel tank may be necessary. See your dealer for
service.
Air Cleaner Filter
Under normal driving conditions, replace the air filter at
the intervals shown on Schedule “A”. If, however, you
drive the vehicle frequently under dusty or severe con-
ditions, the filter element should be inspected periodi-
cally and replaced if necessary at the intervals shown on
Schedule “B”.
WARNING!
The air cleaner can provide a measure of protection
in the case of engine backfire. Do not remove the air
cleaner 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 cleaner removed. Failure to do so can result in
serious personal injury.

Maintenance-Free Battery
The top of the MAINTENANCE-FREE battery is perma-
nently sealed. You will never have to add water, nor is
periodic maintenance required.
NOTE:The battery is stored in a compartment in front
of the tire in the right front fender and is accessible
through the engine compartment. The tire and wheel
need not be removed to access the battery.
To access the battery:
1. Turn the steering wheel fully to the right.
2. Remove the battery access panel from the inner fender
shield.
3. Remove the air cleaner.
4. Move the battery into the opening and lift it out.

Power Steering Fluid Check
WARNING!
Fluid level should be checked with the engine off to
prevent injury from moving parts. Do not overfill.
Use only manufacturer’s recommended power steer-
ing fluid, refer to Recommended Fluids, Lubricants
and Genuine Parts for the correct fluid type.
During scheduled maintenance, check the power steering
fluid level at the power steering fluid reservoir.
Before removing the reservoir cap, wipe the outside of
the cap and reservoir so that no dirt can fall into the
reservoir.
Fluid level should be maintained at the proper level
indicated on the side of the reservoir. If necessary, addfluid to restore to the proper indicated level. With a clean
cloth, wipe any spilled fluid from all surfaces. See your
dealer for the correct power steering fluid for your
vehicle.

Chassis Lubrication
Front Suspension Ball Joints
Inspect these ball joints whenever your vehicle is ser-
viced. They are permanently lubricated and do not
require periodic lubrication.
Steering Linkage
Inspect tie rod ends whenever the vehicle is serviced.
They are permanently lubricated and do not require
periodic lubrication.
Drive Shaft Universal Joints
Your vehicle has four constant velocity universal joints.
Periodic lubrication of these joints is not required. How-
ever, the joint boots should be inspected for external
leakage or damage when other maintenance is per-
formed.
If leakage or damage is evident, replace the universal
joint boot and grease immediately.
Continued operation could result in failure of the univer-
sal joint due to water and dirt contamination of the
grease. This would require complete replacement of the
joint assembly.
Body Mechanism Lubrication
Body and other operating mechanisms and linkages
should be inspected, cleaned, and lubricated, as required,
to maintain ease of operation and to provide protection
against rust and wear.
Before the application of any lubricant, the parts con-
cerned should be wiped clean to remove dust and grit;
after lubricating, excess oil or grease should be removed.

Cooling System
WARNING!
•When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition key
to the OFF position. The fan is temperature con-
trolled and can start at any time the ignition key is
in the ON position.
•You or others can be badly burned by hot coolant
or steam from your radiator. If you see or hear
steam coming from under the hood, don’t 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 coolant 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 radiator and condenser for any
accumulation of bugs, leaves, etc. Clean the radiator and
condenser by gently spraying water from a garden hose
at the back of the core.
Check the engine cooling system hoses for condition and
tightness of connection. Inspect the entire system for
leaks. Any hoses that show cuts or severe abrasion must
be replaced.
Cooling System — Drain, Flush and Refill
At the intervals shown on the Maintenance Schedules (5
years/100,000 miles), the system should be drained,
flushed and refilled.
If the solution is dirty and 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.
Engine Coolant Disposal
Used ethylene glycol based engine coolant is a regulated
substance requiring proper disposal. Check with your
local authorities to determine the disposal rules for your
community. Do not store ethylene glycol based engine
