Exterior 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 1 to 2 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.
Pa i n t C h i p p i n g
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
Washing
CAUTION

Before lifting the windshield wiper
blades off the windshield, always
follow the procedure for moving the
windshield wiper blades. Otherwise,
a wiper blade, wiper arm, or the

the procedure on how to move the
windshield wiper blades to the
service position.
 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.
