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 or damage the finish.
• 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 car wash brushes.
• Do not use any acid detergent. It may
damage and corrode 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 cars 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 corrosion
on your car are:
• Road salt, dirt and moisture that is
allowed to accumulate underneath the
car.
• Removal of paint or protective coatings
by stones, gravel, abrasion or minor
scrapes and dents which leave
unprotected metal exposed to
corrosion.
High-corrosion areas
If you live in an area where your car is
regularly exposed to corrosive materials,
corrosion protection is particularly
important. Some of the common causes
of accelerated corrosion are road salts,
dust control chemicals, ocean air and
industrial pollution.
Moisture breeds corrosion
Moisture creates the conditions in which
corrosion is most likely to occur. For
example, corrosion is accelerated by
high humidity, particularly when
temperatures are just above freezing. In
such conditions, the corrosive material is
kept in contact with the car surfaces by
moisture that is slow to evaporate.
Mud is particularly corrosive because it
dries slowly and holds moisture in
contact with the vehicle. Although the
mud appears to be dry, it can still retain
the moisture and promote corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly
ventilated so the moisture can be
dispersed. For all these reasons, it is
particularly important to keep your car
clean and free of mud or accumulations
of other materials. This applies not only
to the visible surfaces but particularly to
the underside of the car.
