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.
The best time to check the oil level is about 5 minutes
after a fully warmed engine is shut off or before starting
the engine after it has sat overnight.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level between the MIN and MAX markings on the
dipstick. Adding one quart of oil when the reading is at
the MIN mark will result in a MAX reading on these
engines.

CAUTION!
Overfilling or underfilling will cause aeration or
loss of oil pressure. This could damage your engine.
Change Engine Oil
Road conditions and your kind of driving affects the
interval at which your oil should be changed. Check the
following list to decide if any apply to you.
²Day and night temperatures are below 32É F (0É C)
²Stop and Go driving
²Extensive engine idling.
²Driving in dusty conditions
²Short trips of less than 10 miles (16.2 km)

Drive Belts Ð 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 specifications
and procedures shown in the 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 specified mileage. 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.
Engine Air Cleaner Filter
Under normal driving conditions, replace the air filter at
the intervals shown on Schedule ªAº. 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 ªBº.
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.
Engine 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 filter replacement may be necessary.
196 MAINTAINING YOUR 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
DaimlerChrysler Dealership.
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 and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturer recommended
power steering fluid, refer to Recommended Fluids,
Lubricants and Genuine Parts for correct fluid type.

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.

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)
MAINTAINING YOUR VEHICLE 205

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

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
208 MAINTAINING YOUR VEHICLE

Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
Insure nylon tubing in these areas has not melted or
collapsed.
NOTE:Often, fluids such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to ease the assembly of hoses to couplings. There-
fore, oil wetness at the hose-coupling area is not neces-
sarily an indication of leakage. Actual dripping of hot
fluid when systems are under pressure (during vehicle
operation) should be noted before hose is replaced based
on leakage.
NOTE:Inspection of brake hoses should be done
whenever the brake system is serviced and every engine
oil change.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning lamp shows system failure.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, fill brake fluid reservoir to
the top of the fill mark chevron. With disc brakes, fluid
level can be expected to fall as the brake pads wear.
However, low fluid level may be caused by a leak and a
checkup may be needed.
