Appearance Care And Protection From Corrosion
Protection of Body and Paint from Corrosion
Vehicle body care requirements vary according to geo-
graphic 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.

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:
²Road salt, dirt and moisture accumulation.
²Stone and gravel impact.
²Insects, tree sap and tar.
²Salt in the air near seacoast localities.
²Atmospheric fallout/industrial pollutants.
Washing
²
Wash your vehicle regularly. Always wash your ve-
hicle in the shade using a mild car wash soap and rinse
the panels completely with clear water.
²If insects, tar or other similar deposits have accumu-
lated on your vehicle, wash it as soon as possible.
²Use MopartAuto Polish to remove road film and
stains and to polish your vehicle. Take care never to
scratch the paint.
²Avoid using abrasive compounds and power buffing
that may diminish the gloss or thin out the paint
finish.
282 MAINTAINING YOUR VEHICLE

CAUTION!
Do not use abrasive or strong cleaning materials
such as steel wool or scouring powder, which will
scratch metal and painted surfaces.
Special Care
²
If you drive on salted or dusty roads or if you drive
near the ocean, hose off the undercarriage at least once
a month.
²The drain holes in the lower edges of the doors, rocker
panels, and rear liftgate must be kept clear and open.
²If you detect any stone chips or scratches in the paint,
touch them up immediately. The cost of such repairs is
considered the responsibility of the owner.
²If your vehicle is damaged due to an accident or
similar cause which destroys the paint and protectivecoating, have your vehicle repaired as soon as pos-
sible. The cost of such repairs is considered the respon-
sibility of the owner.
²If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., assure that such materials are well
packaged and sealed.
²If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.
²Use MopartTouch-Up Paint on scratches as soon as
possible. Your authorized dealer has touch-up paint to
match the color of your vehicle.
²Aluminum wheels should be cleaned regularly with
mild soap and water to prevent corrosion. To remove
heavy soil, select a nonabrasive, non-acidic cleaner. Do
not use scouring pads or metal polishes. Avoid auto-
matic car washes that use acidic solutions or harsh
brushes that may damage the wheels' protective finish.

Interior Care
Use MopartFabric Cleaner to clean fabric upholstery
and carpeting.
Use MopartVinyl Cleaner to clean vinyl upholstery.
MopartVinyl Cleaner is specifically recommended for
interior vinyl trim.
Do not use silicon based cleaning products on leather
seats. They could cause cracking of the seat leather.
Leather Seat Care & Cleaning
Leather is best preserved by regular cleaning with a
damp soft cloth. Small particles of dirt can act as an
abrasive and damage the leather surface and should be
removed promptly with a damp cloth. Stubborn soils can
be removed easily with a soft cloth and MopartTotalClean. Care should be taken to avoid soaking the leather
with any liquid. Please do not use polishes, oils, cleaning
fluids, solvents, detergents, or ammonia based cleaners
to clean the leather. Application of a leather conditioner is
not required to maintain the original condition.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with any commercial household-type glass cleaner.
Never use an abrasive type cleaner. Use caution when
cleaning inside rear windows equipped with electric
defrosters. Do not use scrapers or other sharp instru-
ments which may scratch the elements.
When cleaning the rear view mirror, spray cleaner on the
towel or rag that you are using. Do not spray cleaner
directly on the mirror.
284 MAINTAINING YOUR VEHICLE

WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas they may cause respiratory harm. Do not
use gasoline, turpentine, kerosene, etc. for cleaning.
Use the Mopartrecommended products or the
equivalents.
Carpet
Vacuum your carpet regularly to prevent a soil build-up.
Shampoo soiled carpet with a reliable upholstery cleaner,
using a natural sponge or soft bristle brush. After carpet
dries, vacuum it thoroughly.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage will also weaken the fabric.If the belts need cleaning, use a mild soap solution or
lukewarm water. Do not remove the belts from the
vehicle to wash them.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
Maintenance After Off-Pavement Driving
After extended operation in mud, sand or water, or
similar dirty conditions, have your brake drums, brake
linings, and axle joints inspected and cleaned as soon as
possible. This will prevent any abrasive material from
causing excessive wear or unpredictable braking action.
Following off-pavement usage, completely inspect the
underbody of your vehicle. Check tires, body structure,
steering, suspension and exhaust system for damage.
Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering and suspen-
sion. Retighten, if required, to torque values specified in
the Service Manual. Also check for accumulations of

vegetation or brush that could become a fire hazard, or
conceal damage to fuel lines, brake hoses, axle pinion
seals, and propeller shafts.
CAUTION!
Under frequent heavy-duty driving conditions,
change all lubricants and lubricate body compo-
nents, all driveline joints and steering linkage more
often than in normal service to prevent excessive
wear.
