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.

▼Active Driving Display
Maintenance*
The dust-proof sheet has a coating.
When cleaning , do
not use a hard or
rough-surface cloth, or cleaning
detergent. In addition, if a chemical
solvent gets on the active driving
display, wipe it o ff immediately. The
dust-proof sheet could be damaged
and the surface coating could be
scratched. Use a fine, soft cloth such as
those used for cleaning eyeglasses.
NOTE
Use of compressed air when cleaning
the dust-proof sheet is recommended.
▼ Panel Maintenance
If a panel becomes soiled, wipe it o
ff
with a soft cloth soaked in clean water
and thoroughly wrung out.
If some areas require further cleaning ,
use the following procedure:
1. Wipe the soiled area with a soft cloth soaked in a mild detergent
(approx. 5 %) diluted with water.
2. Wipe o ff the remaining detergent
using a cloth soaked in clean water
and wrung out well.
NOTE
Be particularly careful when cleaning
shiny surface panels and metallic parts
such as plating as they can be
scratched easily.
▼ Cleaning the Window Interiors
If the windows become covered with
an oily, greasy, or waxy
film, clean
them with glass cleaner. Follow the
directions on the container.
CAUTION
 Do not scrape or scratch the inside
of the window glass. It could
damage the thermal filaments and
the antenna lines.
 When washing the inside of the
window glass, use a soft cloth
dampened in lukewarm water, gently
wiping the thermal filaments and the
antenna lines.
Use of glass cleaning products could
damage the thermal filaments and
the antenna lines.
▼ Cleaning the Floor Mats
Rubber
floor mats should be cleaned
with mild soap and water only.
WARNING
Do not use rubber cleaners, such as
tire cleaner or tire shine, when
cleaning rubber floor mats:
Cleaning the rubber floor mats with
rubber cleaning products makes the
fl oor mats slippery.
This may cause an accident when
depressing the accelerator, brake, or
clutch (Manual transmission) pedal or
when getting in or out of the vehicle.
After removing the floor mats for
cleaning, always reinstall them securely
(page 3-46).

wood blocks of su fficient size if
possible to hold the tire in place.
▼ Removing a Flat Tire
WARNING
When jacking-up a vehicle, always
shift the shift lever to 1st or R position
(manual transmission vehicle) or shift
the selector lever to P position
(automatic transmission vehicle),
apply the parking brake, and place
wheel blocks in the position
diagonally opposed to the jack:
Changing a
flat tire without using
wheel blocks is dangerous because the
vehicle may move and fall o ff the jack
even with the shift lever in 1st or R
position, or the selector lever is in P
position, which could result in an
accident.
1. If your vehicle is equipped with a wheel cover, pry off the wheel
cover with the beveled end of the
jack lever.

NOTE
Force the end of the jack lever
firmly between wheel and cover, or
removal will be di fficult.
