Aluminum Alloy Wheels (US: EX, Canada: EX-R)
CAUTION:
Wash the wheels after driving on snowy or icy roads where salt
has been applied.
Avoid off-road driving. Brush, rocks, dirt, and severe impact
may damage the wheels.
Install tire chains carefully. Improperly installed chains can cause
damage to the wheels.
Honda aluminum wheels are treated with a protective finish.
Wash them with a low-phosphate detergent and sponge. Do not
use abrasive cleaners or stiff brushes.
Always install aluminum wheels in sets of four. If mixed with
other types, the car's handling may be affected.
Rust Prevention
Rusting is likely to occur in parts of the car where water is trapped
or where there is continual dampness.
Water will collect inside doors and body panels if drain holes
become clogged.
Water which seeps under or soaks floor mats will subject floor
sections to prolonged wetness or dampness.
Road dirt or sand, which collects and fills recesses on the
underside of the car, retains moisture long after the rest of the
car has dried.
The removal of paint and undercoating by stones, gravel, and minor
accidents immediately exposes metal to air and moisture.
Rusting is increased by high humidity and by the presence of
corrosive substances in the air or on the roads.
Salt used for road de-icing will coat the bottom of the car and
hasten rusting.
Localities with high humidity have greater potential for rust
problems, especially where salt is also present on the road or in
moist sea air.
Industrial pollution will accelerate the deterioration of paint
finishes and promote rusting.
