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 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 is
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 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 ignition 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.
2. Remove the front tab while slightly
lifting the front of the cover.
3. Remove the cover while lifting it and
sliding it to the rear.
3. If any fuse but the MAIN fuse is
blown, replace it with a new one of the
same amperage rating.
Normal Blown
WARNING
Do not replace the main fuse and
multiplex slow blow fuse by yourself.
Have an Authorized Mazda Dealer
perform the replacement:
Replacing these fuses by yourself is
dangerous because they are high
current fuses. 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.

Appearance Care
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 one to
two hours. After removing the newspaper,
rinse off the loosened debris with water.
