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

If any lights, accessori
es, 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 Authorized
Mazda Dealer as soon as possible.
▼ Fuse Replacement
Replacing the fuses on
the vehicle's left
side
If the electrical system does not work, first
inspect the fuses on the vehicle's left side.

1. Make sure the ignition is switched off,
and other switches are off.
2. Open the fuse panel cover.
3. Pull the fuse straight out with the fuse puller provided on the fuse block
located in the engine compartment.
4. Inspect the fuse and replace it if it isblown.
1. Normal
2. Blown

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. We recommend an
Authorized Mazda Dealer.
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.
CAUTION
Always replace a fuse with a genuine
Mazda fuse or equivalent of the same
rating. Otherwise you may damage the
electric system.
6. Reinstall the cover and make sure that it is securely installed.

Replacing the fuses under the hood
If the headlights or other electrical
components do not work and the fuses in
the cabin are normal, inspect the fuse
block under the hood.
If a fuse is blown, it must be replaced.
Follow these steps:

1. Make sure the ignition is switched off, and other switches are off.
2. Remove the fuse block cover.
3. If any fuse but the MAIN fuse is
blown, replace it with a new one of the
same amperage rating .
1. Normal
2. Blown

WARNING
Do not replace the main fuse by
yourself. Have an Authorized Mazda
Dealer 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.
4. Reinstall the cover and make sure that it is securely installed.

Do not spray water in the engine
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 th e paint surface when:
The vehicle is washed without first
rinsing off 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 stiff.
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 off any dirt or other foreign matter
using lukewarm or cold water before
washing.
Use plenty of luke warm 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.
Pay special attention to removing salt, dirt,
mud, and other forei gn material from the
underside of the fenders, and make sure
the drain holes in the lower edges of the
doors and rocker panels are clean.
