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 o ff all soap with
lukewarm or cold water. Do not allow
soap to dry on the finish.

After washing the vehicle, dry it with a
clean chamois to prevent water spots
from forming.
WARNING
Dry o ff brakes that have become wet
by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to normal:
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
a ff ected.
When using an automatic car wash
Retract the door mirrors.The automatic car wash brushes
could reduce the paint lustre or
hasten paint deterioration.
When using a high water pressure car
wash
High water temperature and high
water pressure car washers are
available depending on the type of car
wash machine. If the car washer nozzle
is put too close to the vehicle, the
force of the spray could damage or
deform the molding , aff ect the
sealability of parts, and allow water to
penetrate the interior. Keep a su fficient
space (30 cm (12 in) or more)
between the nozzle and the vehicle. In
addition, do not spend too much time
spraying the same area of the vehicle,
and be very careful when spraying
between gaps in doors and around
windows.
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.
Wax containing abrasives will
remove paints 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 o ff the wax with a soft cloth.
NOTE
A spot remover to remove oil, tar, and
similar materials will usually also take
o ff the wax. Rewax these areas even if
the rest of the vehicle does not need it.

▼Repairing Damage to the Finish
Deep scratches or chips on the
finish
should be repaired promptly. Exposed
metal quickly rusts and can lead to
major repairs.
CAUTION
If your Mazda is damaged and needs
metal parts repaired or replaced, make
sure the body shop applies
anti-corrosion materials to all parts,
both repaired and new. This will
prevent them from rusting.
▼ Bright-Metal Maintenance
Use tar remover to remove road tar
and insects. Never do this with a
knife or similar tool.
To prevent corrosion on bright-metal
surfaces, apply wax or chrome
preservative and rub it to a high
luster.
During cold weather or in coastal
areas, cover bright-metal parts with a
coating of wax or preservative
heavier than usual. It would also help
to coat them with noncorrosive
petroleum jelly or some other
protective compound.
CAUTION
Do not use steel wool, abrasive
cleaners, or strong detergents
containing highly alkaline or caustic
agents on chrome-plated or anodized
aluminum parts. This may result in
damage to the protective coating and
cause discoloration or paint
deterioration.
▼ Underbody Maintenance
Road chemicals and salt used for ice
and snow removal and solvents used
for dust control may collect on the
underbody. If not removed, they will
speed up rusting and deterioration of
such underbody parts as fuel lines,
frame,
floor pan, and exhaust system,
even though these parts may be coated
with anti-corrosive material.

Thoroughly flush the underbody and
wheel housings with lukewarm or cold
water at the end of each winter. Try
also to do this every month.

Pay special attention to these areas
because they easily hide mud and dirt.
It will do more harm than good to wet
down the road grime without
removing it.

The lower edges of doors, rocker
panels, and frame members have drain
holes that should not be clogged.
Water trapped there will cause rusting.
WARNING
Dry off brakes that have become wet
by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to normal:
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
a ff ected.

▼Aluminum Wheel Maintenance*
A protective coating is provided over
the aluminum wheels. Special care is
needed to protect this coating.
CAUTION
Do not use any detergent other than
mild detergent. Before using any
detergent, verify the ingredients.
Otherwise, the product could discolor
or stain the aluminum wheels.
NOTE
Do not use a wire brush or any
abrasive cleaner, polishing
compound, or solvent on aluminum
wheels. They may damage the
coating.
Always use a sponge or soft cloth to
clean the wheels.
Rinse the wheels thoroughly with
lukewarm or cold water. Also, be
sure to clean the wheels after driving
on dusty or salted roads to help
prevent corrosion.
Avoid washing your vehicle in an
automatic car wash that uses
high-speed or hard brushes.
▼Plastic Part Maintenance
When cleaning the plastic lenses of
the lights, do not use gasoline,
kerosene, recti
fied spirit, paint,
thinner, highly acidic detergents, or
strongly alkaline detergents.
Otherwise, these chemical agents
can discolor or damage the surfaces
resulting in a signi ficant loss in
functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or
battery fluid, it could cause
discoloration, staining , or paint
peeling. Wipe o ff any such chemical
agents or fluids using a soft cloth
immediately.
High water temperature and high
water pressure car washers are
available depending on the type of
high pressure car washer device. If
the car washer nozzle is put too
close to the vehicle or aimed at one
area for an extended period of time,
it could deform plastic parts or
damage the paint.
Do not use wax containing
compounds (polish). Otherwise, it
could result in paint damage.
In addition, do not use an electrical
or air tool to apply wax. Otherwise,
the frictional heat generated could
result in deformation of plastic parts
or paint damage.
