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 is blown.
Normal 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. Consult 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 OUTLET 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 igniti on is switched off,
and other switches are off.
2. Remove the fuse block cover.
NOTE
If the lock is forcefully opened, the fuse
block cover may come in contact with
the frame when it is removed and
become scratched.
When removing the cover, remove it
slowly according to the following
procedure.
1. Disengage the rear lock by
pressing down on the front tab with
your fingers.

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.

Exterior Care
The paintwork on your Mazda represents
the latest technical developments in
composition and methods of application.

Environmental hazards, however, can
harm the paint's protective properties, if
proper care is not taken.

Here are some examples of possible
damage, with tips on how to prevent them.
Etching Caused by Acid Rain or
Industrial Fallout
Occurrence
Industrial pollutants and vehicle emissions
drift into the air and mix with rain or dew
to form acids. These acids can settle on a
vehicle's finish. As the water evaporates,
the acid becomes concentrated and can
damage the finish.
And the longer the acid remains on the
surface, the greater the chance is for
damage.
Prevention
It is necessary to wash and wax your
vehicle to preserve its finish according to
the instructions in this section. These steps
should be taken immediately after you
suspect that acid rain has settled on your
vehicle's finish.
Damage Caused by Bird Dropping,
Insects, or Tree Sap
Occurrence
Bird droppings contain acids. If these are
not removed they can eat away the clear
and color base coat of the vehicle's
paintwork.

When insects stick to the paint surface and
decompose, corrosive compounds form.
These can erode the clear and color base
coat of the vehicle's paintwork if they are
not removed.

Tree sap will harden and adhere
permanently to the paint finish. If you
scratch the sap off while it is hard, some
vehicle paint could come off with it.
Prevention
It is necessary to have your Mazda washed
and waxed to preserve its finish according
to the instructions in this section. This
should be done as soon as possible.

Bird droppings can be removed with a soft
sponge and water. If you are traveling and
these are not available, a moistened tissue
may also take care of the problem. The
cleaned area should be waxed according to
the instructions in this section.
Insects and tree sap are best removed with
a soft sponge and water or a commercially
available chemical cleaner.

Another method is to cover the affected
area with dampened newspaper for 1 to 2
hours. After removing the newspaper,
rinse off the loosened debris with water.

Wa t e r M a r k s
Occurrence
Rain, fog, dew, and even tap water can
contain harmful minerals such as salt and
lime. If moisture containing these minerals
settles on the vehicle and evaporates, the
minerals will concentrate and harden to
form white rings. The rings can damage
your vehicle's finish.
Prevention
It is necessary to wash and wax your
vehicle to preserve its finish according to
the instructions in this section. These steps
should be taken immediately after you find
water marks on your vehicle's finish.
Paint Chipping
Occurrence
Paint chipping occurs when gravel thrown
in the air by another vehicle's tires hits
your vehicle.
How to avoid paint chipping
Keeping a safe distance between you and
the vehicle ahead reduces the chances of
having your paint chipped by flying
gravel.
NOTE
The paint chipping zone varies with the
speed of the vehicle. For example, when
traveling at 90 km/h (56 mph), the paint
chipping zone is 50 m (164 ft).
In low temperatures a vehicle's finish
hardens. This increases the chance of
paint chipping.
Chipped paint can lead to rust forming
on your Mazda. Before this happens,
repair the damage by using Mazda
touch-up paint according to the
instructions in this section. Failure to
repair the affected area could lead to
serious rusting and expensive repairs.

Follow all label and container directions
when using a chemical cleaner or polish.
Read all warnings and cautions.
▼ Maintaining the Finish
Wa s h i n g
CAUTION

When the ignition is switched ON and
the wiper lever is in the AUTO position,
the windshield wipers may operate
automatically in the following cases:
 The area of the windshield above the
rain sensor is touched or wiped with a
cloth.
 The windshield or the rain sensor area
in the cabin is hit.
When the ignition is switched ON and
the wiper lever is in the AUTO position,
do not touch the windshield or the
windshield wipers Otherwise, the
windshield wipers will operate
automatically which could catch your fingers or damage the windshield wipers.
When removing ice or snow, or cleaning
the windshield, always make sure the
wiper lever is in the OFF position.

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 hood.
Otherwise, you could dent the vehicle.
 Do not use automatic car washing
machines and car washing devices using
high water pressure.
 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 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.
Pay special attention to removing salt, dirt,
mud, and other foreign 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.
