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 clear 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. 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
removal of paint and decals.
Special Care
If you drive on salted or dusty roads or if you

drive near the ocean, hose off the undercar-
riage at least once a month.
It is important that the drain holes in the

lower edges of the doors, rocker panels, and
trunk be kept clear and open.
If you detect any stone chips or scratches in

the paint, touch them up immediately. The
cost of such repairs is considered the respon-
sibility of the owner.
If your vehicle is damaged due to a collision

or similar cause that destroys the paint and
protective coating, have your vehicle repaired
as soon as possible. The cost of such repairs
is considered the responsibility of the owner.
