WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for which
you have the knowledge and the proper equipment.
If you have any doubt about your ability to perform
a service job, take your vehicle to a competent
mechanic.
MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides the maintenance items for which there are fixed
maintenance intervals, there are other items that should
operate satisfactorily without periodic maintenance.
However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained, at the correct level. Check
the oil level at regular intervals, such as every fuel stop.

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.

The proper SAE viscosity grade of engine oil should be
selected based on the following recommendations and be
within the operating temperature shown in the engine oil
viscosity charts.
SAE 10W-30 oil is preferred for use in 3.5L engines within
the operating temperatures shown in the viscosity chart.
SAE 5W-30 engine oil is allowed for use in the 3.5L
engine during cold weather only to improve cold
weather starting.SAE 5W-30 oil is preferred for use in 2.7L engines within
the operating temperatures shown in the viscosity chart.
You are encouraged to use SAE 5W-30 oils to aid in low
temperature starting and for improved fuel economy.
Synthetic Engine Oils
There are a growing number of engine oils being pro-
moted as either synthetic or semi-synthetic. If you choose
to use such a product, useonlythose oils that meet the
American Petroleum Institute (API) and SAE viscosity
standard. Follow the service schedule that describes your
driving type.
Materials Added To Engine Oils
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and it’s
performance may be impaired by supplemental addi-
tives.
Disposing of Used Engine Oil
Care should be taken in disposing of used engine oil from
your vehicle. Used oil, indiscriminately discarded, can
present a problem to the environment. Contact your
dealer, service station, or governmental agency for advice
3.5L Engine Oil Chart
MAINTAINING YOUR VEHICLE 177

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.
180 MAINTAINING YOUR VEHICLE

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 positive (+)
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
Check the air conditioning system at the start of the
warm weather season.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser for an accumulation of dirt or insects. Clean with
a gentle water spray from behind the radiator andthrough the condenser as required. Fabric front fascia
protectors may reduce air flow to the condenser, reducing
air conditioning performance.
WARNING!
The 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 repairman.
Refrigerant Recovery and Recycling
The air conditioning system of your vehicle contains
R-134a, a refrigerant that does not deplete the ozone layer
in the upper atmosphere. The manufacturer recommends
that air conditioning service be done by facilities using
refrigerant recyling and recovery equipment that meets
SAE standard J1991.

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.

Hood Latch
When performing other under hood services, the hood
latch release mechanism and safety catch should be
inspected, cleaned, and lubricated.
It is important to maintain proper lubrication to insure
that the hood mechanisms work properly and safely.
Multi-Purpose Lubricant, NLGI Grade 2, should be ap-
plied sparingly to all pivot and sliding contact areas.
External Lock Cylinders
Lubricate the external lock cylinders twice a year, prefer-
ably in the fall and spring. Apply a small amount of
lubricant, such as Mopar Lock Cylinder Lubricant di-
rectly into the lock cylinder (avoid excess lubricant).
Insert the key into the lock cylinder and rotate from the
unlocked to the locked position; without adding more
lubricant. Repeat this procedure three or four times. Wipe
all the lubricant off the key with a clean cloth, to avoid
soiling clothing.
If you use a lubricant that cannot be dispensed directly
into the lock cylinder, apply a small amount of the
lubricant to the key. Insert the key into the lock cylinder,then proceed as described above, to distribute the lubri-
cant within the lock cylinder. Pay attention to trunk
hinges, especially during cold weather, to ensure ease of
trunk operation.
Other Body Mechanisms
The following body mechanisms should be inspected
and, if necessary, all pivot and sliding contact areas of
these components should be lubricated with the lubricant
specified as follows:
Engine Oil
•
Door hinges
•Hood hinges
•Trunk hinges
Smooth White Body Lubricant - Such as Mopar
Spray White Lube:
•
Hood hinge springs and links
•Lock cylinders
•Parking brake mechanism

Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
Insure nylon tubing in these areas has not melted or
collapsed. Inspect all hose connections such as clamps
and couplings to make sure they are secure and no leaks
are present. Components should be replaced immedi-
ately if there is any evidence of degradation that could
cause failure.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in Section 8.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
Brake and Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect surface of hoses for evidence of heat and me-
chanical damage. Hard and brittle rubber, cracking,
checking, tears, cuts, abrasion, and excessive swelling
suggest deterioration of the rubber. Particular attention
should be made to examining those hose surfaces nearest
to high heat sources, such as the exhaust manifold.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
