Some of the most important safe ty precautions are given here.
However, we cannot warn you of every conceivable hazard that can arise in
performing maintenance. Only you can decide whether or not you should perform
a given task.
• To reduce the possibility of fire or explos ion, keep cigarettes, sparks, and flames
away from the battery and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the engine and exhaust can ignite them causing a fire.
• To clean parts, use a co mmercially available degreas er or parts cleaner, not
gasoline.
• Wear eye protection and protective clothi ng when working with the battery or
compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Only operate the engine if th ere is sufficient ventilation.
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on le vel ground, the parking brake is set, and
the engine is off.
• Be aware that hot parts can burn you.
u Make sure to let the engine and exhaust system cool thoroughly before
touching vehicle parts.
• Be aware that moving parts can injure you.

uuCleaning uExterior Care

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. Prom ptly 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.
