uuCleaning uExterior Care
754
Maintenance
A good coat of automotive body wax helps protect your vehicle's paint from the
elements. Wax will wear off over time and expose your vehicle's paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they
may be stained or the coating may peel. Promptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road
contaminants. When necessary, as early as possible use a sponge and mild detergent
to wipe away these contaminants. Do no t use a stiff brush or harsh chemicals
(including some commercial wheel cleaners). These can damage the protective finish
on aluminum alloy wheels, resulting in corrosion. Depending on the type of finish,
the wheels also may lose their luster or appear burnished. To avoid water stains,
wipe the wheels dry with a cloth while they are still wet.

1 Washing the Vehicle
Do not spray water onto the capless unit when the

If you need to lift the wiper arms away from the
windshield, first set the wiper arms to the
maintenance position. 2 Changing the Front Wiper Blade P. 733
