NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the cooling system and turning off the A/C removes this
heat. You can also turn the temperature control to maxi-
mum heat, the mode control to floor, and the fan control
to high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
cooling system.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads ªH,º pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
ªH,º turn the engine off immediately, and call for
service.
WARNING!
A hot cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant. If
your temperature gauge pointer is in the red area,
turn off the engine immediately. You may want to call
an authorized dealer for service. If you decide to look
under the hood yourself, see Section 7 of this manual.
Follow the warnings under the Cooling System Pres-
sure Cap paragraph.
TIREFIT TIRE REPAIR AND JACKING
TIREFIT
Small punctures, particularly those in the tread, can be
sealed with TIREFIT. Foreign objects (e.g., screws or
nails) should not be removed from the tire. TIREFIT can
be used in outside temperatures down to approximately
-4ÉF (-20ÉC).

Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, only use synthetic engine
oils, approved to MB 229.3 or MB 229.5, such as Mobil 1
SAE 0W-40. The FSS may not alert for an oil change at the
proper interval if an unapproved engine oil is used;
engine damage and reduced engine life may result.
Materials Added To Engine Oils
Do not add materials (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and its
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
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 DaimlerChrysler Corporation engines have a full-
flow type disposable oil filter. Use a filter of this type for
replacement. The quality of replacement filters varies
considerably. Only high quality filters should be used to
assure most efficient service. MopartEngine Oil Filters
are high quality oil filters and are recommended.
228 MAINTAINING YOUR VEHICLE
Drive Belts - Check Condition and Tension
At the distance 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 distance 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.
Engine Air Cleaner Filter
Under normal driving conditions, replace the air filter at
each interval called out by FSS.
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. See your
authorized dealer for service.

WARNING!
Battery posts, terminals and related accessories con-
tain lead and lead compounds. Wash hands after
handling.
Battery fluid is a corrosive acid solution and can burn
or even blind you. Don't allow battery fluid to
contact your eyes, skin or clothing. Don't lean over a
battery when attaching clamps. If acid splashes in
eyes or on skin, flush the area immediately with
large amounts of water.
Battery gas is flammable and explosive. Keep flame
or sparks away from the battery. Don't use a booster
battery or any other booster source with an output
greater than 12 volts. Don't allow cable clamps to
touch each other.
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 ªfast chargerº is used while the battery is in the
vehicle, disconnect both vehicle battery cables before
connecting the charger to battery. Do not use a ªfast
chargerº to provide starting voltage as battery dam-
age can result.
Air Conditioner
Check the air conditioning system at the start of the
warm weather season.
232 MAINTAINING YOUR VEHICLE
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 and
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 un-
der 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 repair person.
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 DaimlerChrysler Corpora-
tion recommends that air conditioning service be done by
facilities using refrigerant recycling and recovery equip-
ment that meets SAE standard J1991.
Power Steering Fluid
No power steering fluid service is required. The system is
filled at the factory with Pentosin CHF 11S. Steering noise
and reduced component life may result if an unapproved
fluid is used.
During scheduled maintenance, check the power steering
fluid level at the power steering fluid reservoir. Nor-
mally, it will not be necessary to add power steering
fluid.
MAINTAINING YOUR VEHICLE 233

Points to Remember
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulation on the radiator and being vapor-
ized 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 recovery bottle does not drop when the
engine cools, the cooling system should be pressure
tested for leaks.
²Maintain a coolant concentration of a minimum of 50%
ethylene glycol Extended Life Coolant and high qual-
ity water with recommended antifreeze for proper
corrosion protection of your engine cooling system
that contains aluminum 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
ONLY the correct type thermostat. Other designs may
result in unsatisfactory coolant performance, poor fuel
economy, and increased emissions.
Hoses And Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, checking, tears, cuts, abrasions,
and excessive swelling indicate deterioration of the rub-
ber.
Pay particular attention to the hoses nearest to high heat
sources such as the exhaust manifold. Inspect hose rout-
ing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
MAINTAINING YOUR VEHICLE 241

CAUTION!
Do not overfill. Dirt and water in the transmission
can cause serious damage. To prevent dirt and water
from entering the transmission after checking or
replenishing fluid, make certain that the dipstick cap
is seated properly.
Add fluid, if necessary, to maintain the proper level.
Frequency of Fluid Change
Under normal operation conditions, the fluid installed at
the factory will give satisfactory lubrication for the life of
the vehicle. Fluid changes are not necessary unless the
lubricant has become contaminated with water. If con-
taminated with water, the fluid should be changed im-
mediately.
Special Additives
Do not add any fluid additives to the transmission. The
only exception to this policy is the use of special dyes toaid in detecting fluid leaks. The use of transmission
sealers should be avoided as this may adversely affect
seals.
Appearance Care and Protection from Corrosion
Protection of Body and Paint from Corrosion
Vehicle body protection requirements vary according to
geographic locations and usage. Chemicals that make
roads passable in snow and ice, and those that are
sprayed on trees and road surfaces during other seasons,
are highly corrosive to the metal in your vehicle. Outside
parking, which exposes your vehicle to airborne contami-
nants, road surfaces on which the vehicle is operated,
extreme hot or cold weather and other extreme condi-
tions will have an adverse effect on paint, metal trim, and
underbody protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.
