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.

Exterior Care
Followalllabel and container directions
when using a chemical cleaner or polish.
Read all warnings and cautions.
qMaintaining the Finish
Washing
CAUTION
When the wiper lever is in the AUTO
position and the ignition switch is in the
ON position, the wipers may move
automatically in the following cases:
lIf the windshield above the rain
sensor is touched.
lIf the windshield above the rain
sensor is wiped with a cloth.
lIf the windshield is given a shock.
lIf the rain sensor is given a shock
from inside the vehicle.
Be careful not to pinch hands or fingers
as it may cause injury, or damage the
wipers. When washing or servicing
your Mazda, make sure the wiper lever
is in the OFF position.
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 the paint surface
when:
lThe vehicle is washed without first
rinsing off dirt and other foreign
matter.
lThe vehicle is washed with a rough,
dry, or dirty cloth.
lThe vehicle is washed at a car wash
that uses brushes that are dirty or too
stiff.
lCleansers or wax containing abrasives
are used.
NOTE
lMazda is not responsible for
scratches caused by automatic car
washes or improper washing.
lScratches are more noticeable on
vehicles with darker paint finishes.
To minimize scratches on the vehicle's
paint finish:
lRinse off any dirt or other foreign
matter using lukewarm or cold water
before washing.
lUse plenty of lukewarm or cold water
and a soft cloth when washing the
vehicle. Do not use a nylon cloth.
lRub gently when washing or drying the
vehicle.
lTake your vehicle only to a car wash
that keeps its brushes well maintained.
lDon't use abrasive cleansers or wax
that contain abrasives.

CAUTION
lDon't 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.
lTo prevent damaging the antenna,
remove it before entering a car wash
facility or passing beneath a low
overhead clearance.
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.
Insects, tar, tree sap, bird droppings,
industrial fallout, and similar deposits can
damage the finish if not removed
immediately. When prompt washing with
plain water is ineffective, use a mild soap
made for use on vehicles.
Thoroughly rinse off all soap with
lukewarm or cold water. Don't allow soap
to dry on the finish.
After washing the vehicle, dry it with a
clean chamois to prevent water spots from
forming.
WARNING
Driving with Wet Brakes:
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been affected.
Dry the brakes by driving very slowly
and applying the brakes lightly until
brake performance is normal.
Waxing
Your vehicle needs to be waxed when
water no longer beads on the finish.
Always wash and dry the vehicle before
waxing it. In addition to the vehicle body,
wax the metal trim to maintain its luster.
1. Use wax which contains no abrasives.
Waxes containing abrasive will remove
paint and could damage bright metal
parts.
2. Use a good grade of natural wax for
metallic, mica, and solid colors.
3. When waxing, coat evenly with the
sponge supplied or a soft cloth.
4. Wipe off the wax with a soft cloth.
NOTE
A spot remover to remove oil, tar, and
similar materials will usually also take
off the wax. Rewax these areas even if
the rest of the vehicle doesn't need it.
