blown.
NormalBlown
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 CIGAR circuit.
CAUTION
Always replace a fuse with one 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 oneof the
same amperage rating.

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.

How to Minimize
Environmental Paint Damage
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.
qEtching 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.
qDamage Caused by Bird
Dropping, Insects, or Tree Sap
Occurrence
Bird droppings contain acids. If these
aren't 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 one to
two hours. After removing the newspaper,
rinse off the loosened debris with water.

qWater Marks
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.
qPaint 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
lThe 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).
lIn low temperatures a vehicle's finish
hardens. This increases the chance of paint
chipping.
lChipped 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.
