compartment. Otherwise, it could
result in engine-starting problems or
damage to electrical parts.
 When washing and waxing the
vehicle, be careful not to apply
excessive force to any single area of
the vehicle roof or the antenna.
Otherwise, you could dent the
vehicle or damage the antenna.
 Make sure that the fuel- filler lid is
closed and lock the doors.
Otherwise, the fuel-filler lid may be
forcefully opened by water pressure
causing damage to the vehicle or fuel- filler lid.
To help protect the finish from rust and
deterioration, wash your Mazda
thoroughly and frequently, at least
once a month, with lukewarm or cold
water.

If the vehicle is washed improperly, the
paint surface could be scratched. Here
are some examples of how scratching
could occur.

Scratches occur on the paint surface
when:
The vehicle is washed without first
rinsing o ff dirt and other foreign
matter.
The vehicle is washed with a rough,
dry, or dirty cloth.
The vehicle is washed at a car wash
that uses brushes that are dirty or too sti ff.
Cleansers or wax containing
abrasives are used.
NOTE
Mazda is not responsible for
scratches caused by automatic car
washes or improper washing.
Scratches are more noticeable on
vehicles with darker paint finishes.
To minimize scratches on the vehicle's
paint finish:
Rinse o ff any dirt or other foreign
matter using lukewarm or cold water
before washing.
Use plenty of lukewarm or cold
water and a soft cloth when washing
the vehicle. Do not use a nylon cloth.
Rub gently when washing or drying
the vehicle.
Take your vehicle only to a car wash
that keeps its brushes well
maintained.
Do not use abrasive cleansers or wax
that contain abrasives.
CAUTION
 Do not use steel wool, abrasive
cleaners, or strong detergents
containing highly alkaline or caustic
agents on chrome-plated or
anodized aluminum parts. This may
damage the protective coating; also,
cleaners and detergents may discolor
or deteriorate the paint.
