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.
▼Fuse Replacement
Replacing the fuses on the vehicle's

5. Insert a new fuse of the same
amperage rating , and make sure it
fits tightly. If it does not
fit tightly,
have an expert install it. Consult an
expert repairer (we recommend an
Authorised Mazda Repairer).
If you have no spare fuses, borrow
one of the same rating from a

WARNING
Do not replace the main fuse by
yourself. Have an expert repairer
(we recommend an Authorised
Mazda Repairer) perform the
replacement:
Replacing the fuse by yourself is
dangerous because the MAIN fuse
is a high current fuse. Incorrect
replacement could cause an
electrical shock or a short circuit
resulting in a fire.

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

▼Plastic Part Maintenance
xWhen cleaning the plastic lenses of
the lights, do not use petrol, paraffin,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these
chemical agents can discolour or
damage the surfaces resulting in a
significant loss in functionality. If
plastic parts become inadvertently
exposed to any of these chemical
agents, flush with water immediately.
xIf plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
petrol, oil, engine coolant, or battery
fluid, it could cause discolouration,
staining, or paint peeling. Wipe off
any such chemical agents or fluids
using a soft cloth immediately.
xHigh water temperature and high
water pressure car washers are
available depending on the type of
high pressure car washer device. If
the car washer nozzle is put too
close to the vehicle or aimed at one
area for an extended period of time,
it could deform plastic parts or
damage the paint.
xDo not use wax containing
compounds (polish). Otherwise, it
could result in paint damage.
xIn addition, do not use an electrical
or air tool to apply wax. Otherwise,
the frictional heat generated could
result in deformation of plastic parts
or paint damage.
