STORING THE VEHICLE
If you are storing your vehicle for more than
21 days, we recommend that you take the
following steps to minimize the drain on your
vehicle’s battery:
•
Disconnect the negative cable from battery.
•
Any time you store your vehicle or keep it out
of service (i.e., 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 lubrication to minimize the possibility
of compressor damage when the system is
started again.
BODYWORK
Protection From Atmospheric
Agents
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 sur-
faces 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 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 re-
moval 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 suscep-
tible 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, sol-
vents, 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 clear water.
•
If insects, tar, or other similar deposits have
accumulated on your vehicle, use Mopar Su-
per 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. Take
care never to scratch the paint.
•
Avoid using abrasive compounds and power
buffing that may diminish the gloss or thin out
the paint finish.
CAUTION!
•
Do not use abrasive or strong cleaning
materials such as steel wool or scouring
powder that will scratch metal and painted
surfaces.
•
Use of power washers exceeding 1,200 psi
(8,274 kPa) can result in damage or re-
moval of paint and decals.
