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. 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.
WA R N I N G
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
affected.
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 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.

WA R N I N G
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
affected.
▼ 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.
▼Convertible Top (Soft Top)
Maintenance
The convertible top is made of a special
high-grade material, but if it's not taken
good care of, hardening, staining, and loss
of luster will result. Maintain it under
these guidelines.
Wa s h i n g
Do not wait until the convertible top gets
really dirty before cleaning it. Dirt that's
there too long will cause deterioration.
1. Before washing, remove dust and
coarse particulate with a soft brush.
2. Gently clean the convertible top with a
synthetic neutral detergent, lots of
water, and a soft brush.
3. Rinse it thoroughly with clean water to
remove all the soap.
4. Wipe it as dry as you can before the
water dries on it.
5. Then allow it to dry completely before lowering it.
CAUTION
Automatic and high-pressure car washes
are harmful to a convertible top. Avoid
them.
 Do not spray water directly on the area
where the window glass and the
convertible top meet. This would
probably cause water to enter the cabin.

 Tire sealant that comes into contact with
the eyes and skin is dangerous. If tire
sealant enters the eyes or contacts the
skin, flush immediately with large
amounts of water and seek medical
assistance.

The tire sealant cannot be reused.
Purchase new tire sealant at an
Authorized Mazda Dealer.

6. Shake the tire sealant well.
CAUTION
If the bottle is shaken after the injection
hose is screwed on, tire sealant could
spray out from the injection hose. Tire
sealant contacting clothing or other
objects may be impossible to remove.
Shake the bottle before screwing on the
injection hose.
NOTE
The sealant hardens easily and
injecting it will be difficult under cold
weather conditions (0 °C (32 °F) or
below). Warm the sealant inside the
vehicle to facilitate injection.
7. Remove the cap from the bottle. Screw
on the injection hose with the bottle's
inner cap left on to break the inner cap.

Overheating
If the high engine coolant temperature
warning light turns on, the vehicle loses
power, or you hear a loud knocking or
pinging noise, the engine is probably too
hot.
WA R N I N G
Pull over to a safe location, then switch
the ignition off and make sure the fan is
not running before attempting to work
near the cooling fan:
Working near the cooling fan when it is
running is dangerous. The fan could
continue running indefinitely even if the
engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and radiator
are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot out
under pressure and cause serious injury.
Open the hood ONLY after steam is no
longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the high engine c oolant temperature
warning light turns on:

1. Drive safely to the side of the road and park off the right-of-way.
2. Put a vehicle with an automatic transmission in park (P), a manual
transmission in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from the engine
compartment.

If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.

If neither coolant nor steam is
escaping:
Open the hood and idle the engine
until it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an Authorized Mazda
Dealer.
6. Make sure the cooling fan is operating, then turn off the engine after the
temperature has decreased.
