Refrigerant Recovery and Recycling
R-134a Air Conditioning Refrigerant is a hydrofluorocar-
bon (HFC) that is endorsed by the Environmental Pro-
tection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by dealers or other service facilities
using recovery and recycling equipment.

NOTE:

Use only manufacturer approved A/C System

Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oil, or Refrigerants.

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.

⬙

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 manufacturers recommended
power steering fluid.

If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to Recommended Fluids, Lubricants, and
Genuine Parts for correct fluid types.

Front Suspension Ball Joints
There are two front suspension lower ball joints that are
permanently lubricated. Inspect these ball joints when-
ever under vehicle service is done. Damaged seals and
their corresponding potentially damaged ball joints must
be replaced.

Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, doors, deck lid and hood hinges, should be
lubricated periodically to assure quiet, easy operation
and to protect against rust and wear. Prior to the appli-
cation of any lubricant, the parts concerned should be
wiped clean to remove dust and grit; after lubricating
excess oil and grease should be removed. Particular
attention should also be given to hood latching compo-
nents to insure proper function. When performing other
underhood services, the hood latch, release mechanism
and safety catch should be cleaned and lubricated.

The external lock cylinders should be lubricated twice a
year, preferably in the fall and spring. Apply a small
amount of a high quality lubricant such as Mopar

威 Lock

Cylinder Lubricant directly into the lock cylinder.

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 or use the washer solvent. This
will remove accumulations of salt, waxes or road film
and help reduce streaking and smearing.

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. make sure that
they are not frozen to the glass before turning them on to
avoid damaging the blade. Keep the blade rubber out of
contact with petroleum products such as engine oil,
gasoline, etc.

Windshield Wiper Blade Replacement

1. Lift the wiper arm away from the glass.

2. Push the release tab shown in the illustration and slide
the wiper blade assembly down along the arm. Gently
place the wiper arm on the windshield.

3. Install the new blade assembly onto the wiper arm tip
until it locks in place.

Windshield Washer Reservoir
The washer fluid reservoir is located in the rear of the
engine compartment on the passenger side and should be
checked for fluid level at regular intervals. Fill the
reservoir with windshield washer solvent (not radiator
antifreeze).

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 technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, 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 an oil
change or lubrication. Replace as required.

WARNING!

Exhaust gases can injure or kill. They contain carbon
monoxide which is colorless and odorless. Breathing
it can make you unconscious and can eventually
poison you. Follow the above precautions to keep
your exhaust system as safe as possible.

Cooling System

WARNING!

• When working near the radiator cooling fan, dis-

connect the fan motor lead or turn the ignition
switch to the OFF position. The fan is temperature
controlled and can start at any time the ignition
switch 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 engine coolant (antifreeze) 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 for an accumulation of
bugs, leaves, etc. Clean the radiator by gently spraying
water from a garden hose at the back of the core.

Check the coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks.

272

MAINTAINING YOUR VEHICLE

With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
coolant from the radiator drain cock. If the cap is sealing
properly, the engine coolant (antifreeze) will begin to
drain from the coolant recovery bottle. DO NOT RE-
MOVE THE COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.

Cooling System — Drain, Flush and Refill
At the intervals shown on the Maintenance Schedules,
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. Discard oil antifreeze
solution.

Selection Of Coolant
Use only the manufacturers recommended coolant, refer
to Recommended Fluids, Lubricants and Genuine Parts
for correct coolant type.

CAUTION!

Mixing of coolants other than specified engine cool-
ants, may result in engine damage that may not be
covered under the new vehicle warranty, and de-
creased corrosion protection. If a non-HOAT coolant
is introduced into the cooling system in an emer-
gency, it should be replaced with the specified
coolant as soon as possible.

Do not use plain water alone or alcohol base engine
coolant (antifreeze) products. Do not use additional
rust inhibitors or antirust products, as they may not
be compatible with the radiator engine coolant and
may plug the radiator.

This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propylene
Glycol based coolants is not recommended.

Adding Coolant
When adding coolant, or refilling the system, a minimum
solution of 50% recommended HOAT ethylene glycol
engine coolant (antifreeze) and distilled water should be
used. Use higher concentrations (not to exceed 70%) if
temperatures below

⫺37°C (⫺34°F ) are anticipated.

Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant solution.
The use of lower quality water will reduce the amount of
corrosion protection in the engine cooling system.

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.

NOTE:

Mixing coolant types will decrease the life of the

engine coolant and will require more frequent coolant
changes.

274

MAINTAINING YOUR VEHICLE

Cooling System 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 recovery bottle.

The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.

WARNING!

The warning words “DO NOT OPEN HOT” 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.

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. To prevent ingestion by animals or children
do not store ethylene glycol based engine coolant in open
containers or allow it to remain in puddles on the
ground. If ingested by a child, contact a physician
immediately. Clean up any ground spills immediately.

Coolant Level
The coolant recovery bottle provides a quick visual
method for determining that the coolant level is ad-
equate. With the engine idling, and warm to normal
operating temperature, the level of the coolant in the
bottle should be between the “FULL” and “ADD” marks.

The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
coolant freeze point or replacing coolant. Advise your

MAINTAINING YOUR VEHICLE

275

service attendant of this. As long as the engine operating
temperature is satisfactory, the coolant recovery bottle
need only be checked once a month.

When additional coolant is needed to maintain the
proper level, it should be added to the coolant recovery
bottle. Do not overfill.

Points To Remember

NOTE:

When the vehicle is stopped after a few kilome-

ters (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 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.

• Do not overfill the coolant recovery bottle.
• Check coolant freeze point in the system.
• If frequent coolant additions are required, the cooling

system should be pressure tested for leaks.

• Maintain coolant concentration at 50% HOAT ethylene

glycol engine coolant (minimum) and distilled water
for proper corrosion protection of your engine which
contains aluminum components.

• Make sure that the radiator and coolant recovery

bottle hoses are not kinked or obstructed.

• Keep the front of the radiator clean. If your vehicle has

air conditioning, keep the front of the condenser clean,
also.

276

MAINTAINING YOUR VEHICLE

• Do 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 gas
mileage, 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, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.

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.

Insure nylon tubing in these areas has not melted or
collapsed.

Inspect all hose connections such as clamps and cou-
plings to make sure the are secure and no leaks are
present.

Components should be replaced immediately if there is
any evidence of degradation that could cause failure.

Fuel System Connections
Electronic Fuel Injection high pressure fuel systems are
designed with tubes and special connects, connections
and clamps which have unique material characteristics to
provide adequate sealing and resist attack by deterio-
rated gasoline.

You are urged to use only the manufactures-specified
tubes, connections and clamps, or their equivalent in
material and specification, in any fuel system servicing.

Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the Mainte-
nance Section.

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 the surface of the hoses and nylon tubing for
evidence of heat and mechanical damage. Hard and

brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling suggest deterioration of the rubber. Particu-
lar 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.

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 a hose is replaced
based on leakage.

278

MAINTAINING YOUR VEHICLE

NOTE:

Inspection of brake hoses should be done when-

ever the brake system is serviced and at 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.

Brake 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 is on.

Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake

fluid reservoir. Fluid level can be expected to fall as the
brake pads wear. Brake fluid level should be checked
when pads are replaced. However, low fluid level may be
caused by a leak and a checkup may be needed.

Use only manufacturers recommended brake fluid, refer
to Recommended Fluids, Lubricants and Genuine Parts
for correct fluid type.

WARNING!

Use of a brake fluid that may have a lower initial
boiling point or unidentified as to specification, may
result in sudden brake failure during hard pro-
longed braking. You could have an accident.

WARNING!

Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.

Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter.

Do not allow petroleum based fluid to contaminate the
brake fluid as seal damage will result!

Automatic Transaxle
All front wheel drive vehicles have a transmission and
differential assembly contained within a single housing.

Selection Of Lubricant
It is important that the proper lubricant is used in the
transaxle to assure optimum transaxle performance. Use
only manufacturers recommended transmission fluid,
refer to Recommended Fluids, Lubricants and Genuine
Parts for correct fluid type. It is important that the
transmission fluid be maintained at the prescribed level
using the recommended fluid.

280

MAINTAINING YOUR VEHICLE

CAUTION!

Using a transmission fluid other than the manufac-
turers recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturers recommended fluid will result in
more frequent fluid and filter changes. Refer to
Recommended Fluids, Lubricants and Genuine Parts
for correct fluid type.

Fluid Level Check
The fluid level in the automatic transaxle should be
checked whenever the vehicle is serviced. Operation with
an improper fluid level will greatly reduce the life of the
transaxle and of the fluid.

Procedure For Checking Fluid Level
To properly check the automatic transaxle fluid level, the
following procedure must be used:

1. The vehicle must be on level ground.

2. The engine should be running at curb idle speed for a
minimum of 60 seconds.

3. Fully apply parking brake.

4. Place the gear selector momentarily in each gear
position ending with the lever in P (PARK).

5. Remove the dipstick and determine if the fluid is hot
or warm. Hot fluid is approximately 180°F (82°C), which
is the normal operating temperature after the vehicle has
been driven at least 15 miles (24 km). The fluid cannot be
comfortable held between the finger tips. Warm is when
the fluid is between 85° to 125°F (29° to 52°C).

6. Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.

If the fluid is hot, reading should be in the cross hatched
area marked “HOT” between the upper two holes in the
dipstick.

If the fluid is cold, the fluid level should be between the
lower two holes, into the area marked “LOW”.

If the fluid level shows low, add sufficient transmission
fluid to bring to the proper level.

MAINTAINING YOUR VEHICLE

CAUTION!

Do not overfill. Dirt and water in the transaxle can
cause serious damage. To prevent dirt and water
from entering the transaxle after checking or replen-
ishing fluid, make certain that the dipstick cap is
seated properly.

Fluid And Filter Changes
Automatic transmission fluid and filter should be
changed as follows:

Maintenance schedule “A”—Turbo Charged Engines

–

No change necessary.

Maintenance schedule “B”

– Every 60,000 miles (96 000

km) change fluid and filter under the following condi-
tions:

• Police, taxi, limousine, commercial type operation, or

trailer towing where the vehicle is driven regularly for
more than 45 minutes of continuous operation.

NOTE:

Refer to Section 8 of this instruction for mainte-

nance schedules.

If the transaxle is disassembled for any reason, the fluid
and filter should be changed.

Special Additives
The manufacturer recommends against the addition of
any fluid additives to the transaxle. The only exception to
this policy is the use of special dyes to aid in detecting
fluid leaks. The use of transmission sealers should be
avoided as they may adversely affect seals.
