223 Car care
What causes rust?
Steel body panels of automobiles are sub-
ject to rusting whenever air and moisture
manage to penetrate the protective finish.
Body panels may rust through if the process
is unchecked. Rusting can occur wherever
water is trapped or where the car’s panels
are continuously damp.
Damage to paint and undercoating by
stones, gravel and minor crashes immedi-
ately exposes metal to air and moisture.
Road salts used for de-icing will collect on
the bottom of the car and promote rusting.
Areas of the country with high humidity have
a greater potential for rust problems, espe-
cially where salt is used on roads or there is
moist sea air. Industrial pollution (fallout)
may also damage paint and promote rust-
ing.
Preventive maintenance
The following procedures are necessary to
help protect against rusting. Refer also to
the terms and conditions of the Performa-
tion Limited Warranty described in the war-
ranty booklet.
1 Wash the car frequently, and wax at
least twice a year. Under adverse con-
ditions, where there is a rapid buildup of
dirt, sand or road salt, wash your car at
least once a week. After extreme expo-
sure to salted snow or slush, evidenced
by a white film on the car, wash the car
immediately. Frequent washing will pre-
vent paint damage from acid rain and
other airborne contaminants such as
tree sap and bird droppings. If any of
these contaminants are noticed on the
car the finish should be washed immedi-
ately.
• Begin washing by rinsing the entire car
with water to loosen and flush off heavy
concentrations of dirt (include the
underbody).
• Sponge the car with a solution of either
a good quality car soap or mild general
purpose (dish washing) detergent and
water.
• Rinse car thoroughly with clean water.
• After washing, check and clear all
drains in doors and body panels.
• Wipe the car dry, preferably using a
chamois.
2 Clean the underside of the car during
the winter. Use high pressure water to
clean the car’s underside (floor panels,
wheel wells) at least at mid-winter and in
the spring.
3 Inspect the car frequently for leaks or
damage, and arrange for needed
repairs promptly. After washing or
after heavy rain, check for leaks. When
washing the car inspect body surfaces
for paint damage. While checking for
leaks, lift the floor mats and check
underneath them. Water can collect in
these areas and remain for prolonged
periods. Dry any wet areas including the
floor mats. Have leaks repaired as soon
as possible.
Use touch
- up paint to repair small
scratches or minor finish damage. Areas
where metal is exposed will rust quickly
and MUST be repaired immediately by
touch-up or professional repainting.
Rust must be removed, the bare metal
primed and painted. Major body
damage should be repaired immediately
and new panels or exposed areas
should be undercoated with anti- corro-
sion material.
Repairs of this type are the owner’s
responsibility and are not covered under
warranty.
