Fuses
▼Fuses
Your vehicle's electrical system is
protected by fuses.

If any lights, accessories, or controls do
not work, inspect the appropriate
circuit protector. If a fuse has blown,
the inside element will be melted.

If the same fuse blows again, avoid
using that system and consult an expert
repairer (we recommend an
Authorised Mazda Repairer) as soon as
possible.

If you have no spare fuses, borrow
one of the same rating from a
circuit not essential to vehicle
operation, such as the audio or
accessory socket circuit.

Always replace a fuse with a
genuine Mazda fuse or equivalent
of the same rating. Otherwise, you
may damage the electric system.

¾Do not spray water in the engine
compartment. Otherwise, it could
result in engine-starting problems or
damage to electrical parts.
¾When washing and waxing the
vehicle, be careful not to apply
excessive force to any single area of
the vehicle roof. Otherwise, you
could dent the vehicle.
¾Make sure that the fuel-filler flap is
closed and lock the doors.
Otherwise, the fuel-filler flap may be
forcefully opened by water pressure
causing damage to the vehicle or
fuel-filler flap.
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:
xThe vehicle is washed without first
rinsing off dirt and other foreign
matter.
xThe vehicle is washed with a rough,
dry, or dirty cloth.
xThe vehicle is washed at a car wash
that uses brushes that are dirty or too
stiff.
xCleansers or wax containing
abrasives are used.
NOTE
xMazda is not responsible for
scratches caused by automatic car
washes or improper washing.
xScratches are more noticeable on
vehicles with darker paint finishes.
To minimize scratches on the vehicle's
paint finish:
xRinse off any dirt or other foreign
matter using lukewarm or cold water
before washing.
xUse plenty of lukewarm or cold
water and a soft cloth when washing
the vehicle. Do not use a nylon cloth.
xRub gently when washing or drying
the vehicle.
xTake your vehicle only to a car wash
that keeps its brushes well
maintained.
xDo not use abrasive cleansers or wax
that contain abrasives.
CAUTION
¾Do not use steel wool, abrasive
cleaners, or strong detergents
containing highly alkaline or caustic
agents on chrome-plated or
anodised aluminium parts. This may
damage the protective coating; also,
cleaners and detergents may
discolour or deteriorate the paint.
Pay special attention to removing salt,
dirt, mud, and other foreign material
from the underside of the wings, and
make sure the drain holes in the lower
edges of the doors and rocker panels
are clean.

Insects, tar, tree sap, bird droppings,
industrial fallout, and similar deposits
can damage the finish if not removed
immediately. When prompt washing
