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.

qRepairing 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.
qBright-Metal Maintenance
lUse tar remover to remove road tar and
insects. Never do this with a knife or
similar tool.
lTo prevent corrosion on bright-metal
surfaces, apply wax or chrome
preservative and rub it to a high luster.
lDuring 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
Don't 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.
qUnderbody 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
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.
