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 serviced 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.
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, to the manufacturer's specifications, should be
obtained immediately.
To minimize the possibility of catalyst damage:
²Do not shut off the engine or interrupt the ignition
when the transaxle 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 for prolonged period.
Engine Timing Belt
Replace the engine timing belt (2.4L Only) 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 Positive Crankshaft Ventilation
(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.
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 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.

through 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 recycling and recovery equipment that meets
SAE standard J1991.
Power Steering Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
ªDaimlerChrysler Dealershipº.
Before removing the reservoir cap, wipe the outside of
the cap and reservoir so that no dirt can fall into the
reservoir.
WARNING!
Fluid level should be checked on a level surface with
the engine off to prevent injury from moving parts,
and to insure accurate fluid level reading. Do not
overfill. Use only the manufacturer's recommended
fluid.

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
²
Door hinges
²Hood hinges
²Trunk hinges
Smooth White Body Lubricant - Such as Mopar
Spray White Lube:
²
Hood hinge springs and links
²Lock cylinders
²Parking brake mechanism
²Trunk latches
²Ash tray

Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild non abrasive cleaner. This will remove accumula-
tions of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield. Avoid using the wiper blades to
remove frost or ice from the windshield. Keep the blade
rubber out of contact with petroleum products such as
engine oil, gasoline, etc.
Windshield Wiper Blade Replacement
²
Lift the wiper arm away from the glass.
²Push the release tab and slide the wiper blade assem-
bly away from the wiper arm. Gently place the wiper
arm on the windshield.
²Install the new blade assembly onto the wiper arm tip
until it locks in place.
Windshield Washers
The fluid reservoir in the engine compartment should be
checked for fluid level at regular intervals. Fill the
reservoir with windshield antifreeze (not radiator anti-
freeze) rated not to freeze at -25ÉF (-31ÉC). Operate the
system for a few seconds to flush out the residual water.

WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if exhaust fumes can be detected inside the vehicle; or
when the underside or rear of the vehicle is damaged;
have a competent mechanic inspect the complete exhaust
system and adjacent body areas for broken, damaged,
deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep
into the passenger compartment. In addition, inspect the
exhaust system each time the vehicle is raised for lubri-
cation or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, fol-
low the preceding safety tips.

Cooling System
Inspection
WARNING!
²When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition key
to the OFF position. The fan is controlled by both
the temperature of the engine cooling system and
the pressure in the air conditioning system and
can start at any time the ignition key is in the ON
position.
²You 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 or cap is hot.
Coolant Checks
Check coolant protection every 12 months (before the
onset of freezing weather, where applicable). If coolant isdirty or rusty in appearance, the system should be
drained, flushed and refilled with fresh coolant.
Check the front of the radiator for any accumulation of
bugs, leaves, etc. Clean the radiator by gently spraying
water from a garden hose at the back of the core.
Check the recovery bottle tank tubing for condition and
tightness of connections at the bottle. Inspect the entire
system for leaks.
Do not remove the cap when the cooling system is hot.(2.7L Engine Shown)

Cooling System Ð Drain, Flush and Refill
At the intervals shown on the Maintenance Schedules,
the system should be drained, flushed and refilled. The
first change should not be required until 5 years or
100,000 miles (160,000 km), whichever comes first. The
coolant should be flushed and changed every two years
or 36,000 miles (57,600 km) thereafter.
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. Used automotive
antifreeze is a recyclable commodity. Discard or recycle
as facilities exist in your area.
Selection Of Coolant
Use only the manufacturer's recommended coolant, refer
to Recommended Fluids, Lubricants and Genuine Parts
for correct coolant type.
CAUTION!
Failure to use the proper antifreeze could cause
radiator plugging and engine overheating. Do not
mix antifreeze brands or use plain water alone or
alcohol base antifreeze products. Do not use addi-
tional rust inhibitors or antirust products, as they
may not be compatible with the radiator coolant and
may plug the radiator or heater core.
Adding Coolant
When adding coolant, a solution of 50% ethylene glycol
antifreeze coolant in distilled water should be used. Use
higher concentrations (not to exceed 60%) if temperatures
below -32ÉF (-35ÉC) are anticipated.
Please note that it is the owner's responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
206 MAINTAINING YOUR VEHICLE

Coolant Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to insure that coolant will return to the
radiator from the coolant reserve tank.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
The warning words ªDO NOT OPEN HOTº on the
cooling system pressure cap are a safety precaution.
Never add coolant when the engine is overheated.
Do not loosen or remove the cap to cool an over-
heated engine. Heat causes pressure to build up in
the cooling system. To prevent scalding or injury, do
not remove the pressure cap while the system is hot
or under pressure.
CAUTION!
Be sure to use only the cooling system pressure cap
specified for your vehicle. Use of any other pressure
cap may result in decreased engine cooling system
performance and/or damage to your vehicle.
Disposal Of Used Engine Coolant
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
coolant in open containers or allow it to remain in
puddles on the ground. Prevent ingestion by animals or
children. If ingested by a child, contact a physician
immediately.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine off and cold, the coolant level should be between
the ªMINº and ªMAXº marks on the side of the coolant
bottle. Some darkening of the coolant bottle will occur
MAINTAINING YOUR VEHICLE 207

over time. This is normal. If the coolant level is hard to
see, jostling the coolant bottle will make it easier to see.
There is no need to remove the radiator cap unless
checking for coolant freeze point, adding, or replacing
coolant. Advise your service attendant of this. As long as
the engine operating temperature is satisfactory, the
coolant bottle need only be checked once a month. Heater
performance may also be adversely affected by low
coolant levels.
When additional coolant is needed to maintain the
proper level, it should be added to the coolant bottle. Do
not overfill. Special procedures are required when filling
the engine cooling system of the 2.7L Engine. See your
authorized dealer for details.
Points to Remember
NOTE:
When the vehicle is stopped after a few miles of
operation, you may observe vapor coming from the front
of the engine compartment. This is normally a result of
moisture from rain, snow, or high humidity accumulating
on the radiator and being vaporized when the thermostat
opens, allowing hot water to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
²Do not overfill the coolant bottle.
²Check coolant freeze point in the system.
²If frequent coolant additions are required, or if the
level in the bottle does not drop when the engine cools,
the cooling system should be pressure tested for leaks.
²Maintain coolant concentration of 50% ethylene glycol
(minimum) with recommended antifreeze for proper
corrosion protection of your engine that contains alu-
minum components.
²Make sure that the radiator and coolant bottle hoses
are not kinked or obstructed.
²Keep the front of the radiator clean. If your vehicle has
air conditioning, keep the front of the condenser clean,
also.
²Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
