226SERVICING AND MAINTENANCE
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 level of the engine
coolant (antifreeze) in the bottle should be
between the ranges indicated on the bottle.
The radiator normally remains completely full, so
there is no need to remove the radiator/coolant
pressure cap unless checking for engine coolant
freeze point 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.
When additional engine coolant is needed to
maintain the proper level, only OAT coolant that
meets the requirements of FCA Material Standard
MS.90032 should be added to the coolant bottle.
Do not overfill.
Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilo -
meters 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 engine coolant (antifreeze) 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 expansion bottle.
Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant needs to be added, the contents of the
coolant expansion bottle must also be protected
against freezing.
If frequent engine coolant additions are
required, the cooling system should be pressure
tested for leaks.
Maintain engine coolant concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corro
-
sion protection of your engine which contains
aluminum components.
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning, keep
the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces -
sary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine cooling performance, poor gas mileage,
and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically Ú page 210.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the Brake System Warning Light
indicates system failure.
Check the fluid level in the master cylinder when
performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up to
the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because it
may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. 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
would not have your full braking capacity in an
emergency.

VEHICLE STORAGE
If you are leaving your vehicle dormant for more
than 3 weeks, you may want to take these steps to
protect your battery.
Disconnect the negative cable from the battery.
Anytime you store your vehicle, or keep it out of
service (e.g., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in the fresh air and high blower
setting. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
BODYWORK
PROTECTION FROM ATMOSPHERIC
A
GENTS
Vehicle body care 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 contaminants, road surfaces on
which the vehicle is operated, extreme hot or cold
weather and other extreme conditions 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.
The most common causes are:
Road salt, dirt and moisture accumulation.
Stone and gravel impact.
Insects, tree sap and tar.
Salt in the air near seacoast localities.
Atmospheric fallout/industrial pollutants.
BODY AND UNDERBODY MAINTENANCE
Cleaning Headlights
Your vehicle is equipped with plastic headlights
and fog lights that are lighter and less susceptible
to stone breakage than glass headlights.
Plastic is not as scratch resistant as glass and
therefore different lens cleaning procedures must
be followed.
To minimize the possibility of scratching the lenses
and reducing light output, avoid wiping with a dry
cloth. To remove road dirt, wash with a mild soap
solution followed by rinsing.
Do not use abrasive cleaning components,
solvents, steel wool or other aggressive material to
clean the lenses.
PRESERVING THE BODYWORK
Washing
Wash your vehicle regularly. Always wash your
vehicle in the shade using Mopar® Car Wash, or
a mild car wash soap, and rinse the panels
completely with water.
If insects, tar, or other similar deposits have
accumulated on your vehicle, use Mopar®
Super Kleen Bug and Tar Remover to remove.
Use a high quality cleaner wax, such as Mopar®
Cleaner Wax to remove road film, stains and to
protect your paint finish. Use care to never the
scratch the paint.
Avoid using abrasive compounds and power
buffing that may diminish the gloss or thin out
the paint finish.
