Yo u r v e h i c l e’s electrical system is
protected by fuses.
If any lights, accessories, or controls don ’t
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 front
passenger

6. Inspect it and replace if it’s blown.
7. Push in a new fuse of the same amperage rating, and make sure it fits
tightly. If it doesn ’t, have an
Authorized Mazda Dealer install it.
If you have no spare fuses, borrow one
of the same rating from a circuit not
essential to vehicle operation, such as
the MIRROR or CIGAR circuit.
Replacing the fuses under the hood
If the headlights or other electrical
components don ’t work and the fuses in
the cabin are OK, inspect the fuse block
under the hood. If a fuse is blown, it must
be replaced. Follow these steps:
1. Turn off the ignition switch and all other switches. 2. Remove the fuse block cover.
3. If a fuse is blown, replace it with a new
one of the same amperage rating
.
Always replace a fuse with one of the
same rating. Otherwise you may
damage the electric system.

Appearance 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
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.

Water 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.

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.
