Maintenance
Bright-metal maintenance
To remove road tar and insects,
use a tar remover, not a scraper or
other sharp object.
To protect the surfaces of bright-
metal parts from corrosion, apply a
coating of wax or chrome preser-
vative and rub to a high luster.
During winter weather or in coastal
areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
Underbody maintenance
Road salt and other corrosive chemi-
cals are used in cold weather states to
melt snow and prevent ice accumula-
tion. If these chemicals are not regu-
larly removed, they will corrode the
vehicle underbody and over time dam-
age fuel lines, the fuel tank retention
system, the vehicle suspension, the
exhaust system, and even the body
frame. The National Highway Traffic
Safety Administration has warned all
vehicle owners of all brands of the
need to take the following steps:
Wash the undercarriage of your
vehicle regularly during the winter
and whenever your vehicle has
been exposed to such salts or
chemicals.
Do a thorough washing of the
undercarriage at the end of the
winter.
Use professional service techni-
cians or governmental inspection
stations to annually inspect for cor-
rosion. Immediately seek an inspection of
your vehicle if you become visually
aware of corrosion flaking or scal-
ing or if you become aware of a
change in vehicle performance,
such as soft or spongey brakes,
fluids leaking, impairment of direc-
tional control, suspension noises
or rattling metal straps.

Aluminum wheel maintenance
The aluminum wheels are coated with
a clear protective finish.
Do not use any abrasive cleaner,
polishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch the finish.
Clean the wheel when it has cooled.
Use only a mild soap or neutral
detergent, and rinse thoroughly with
water. Also, be sure to clean the
wheels after driving on salted roads.
This helps prevent corrosion.
Avoid washing the wheels with high-
speed vehicle wash brushes.
Do not use any alkaline or acid
detergents It may damage and cor-
rode the aluminum wheels coated
with a clear protective finish.
Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design
and construction practices to combat
corrosion, we produce vehicles of
the highest quality. However, this is
only part of the job. To achieve the
long-term corrosion resistance your
vehicle can deliver, the owner's
cooperation and assistance is also
required.
Common causes of corrosion
The most common causes of corro-
sion on your vehicle are:
Road salt, dirt and moisture that is
allowed to accumulate underneath
the vehicle.
Removal of paint or protective
coatings by stones, gravel, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion.WARNING
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.
