When selecting heat, the system will
restrict airflow until it has warmed to
prevent cold air from blowing out of the
vents.
▼Windshield Defrosting and
Defogging
Set the mode selector dial to the
position and turn the f
an control dial to the
desired speed.
In this position, the outside air position is
automatically selected, and when the fan
control dial is ON, the air conditioner
automatically turns on. The air conditioner
will directly dehumidify the air to the front
windshield and side windows (page 5-4).
Airflow amount will be increased.
WA R N I N G
Set the temperature control to the hot or
warm position when defogging (
position):
Using the
position with the temperature
control set to the cold position is dangerous
as it will cause the outside of the
windshield to fog up. Your vision will be
hampered, which could lead to a serious
accident.
NOTE
Use the temperature control dial to
increase the air flow temperature and
defog the windshield more quickly.

Wiper Blades
CAUTION
Hot waxes applied by automatic car
washers have been known to
affect the
wiper's ability to clean windows.
 To prevent damage to the wiper blades,
do not use gasoline, kerosene, paint
thinner, or other solvents on or near
them.
 When the wiper lever is in the AUTO
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 If the windshield above the rain sensor
is touched.
 If the windshield above the rain sensor
is wiped with a cloth.
 If the windshield is struck with a hand
or other object.
 If the rain sensor is struck with a hand
or other object 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 the
vehicle, make sure the wiper lever is in
the OFF position.
Contamination of either the windshield or
the blades with foreign matter can reduce
wiper effectiveness. Common sources are
insects, tree sap, and hot wax treatments
used by some commercial car washes.

If the blades are not wiping properly, clean
the window and blades with a good
cleaner or mild detergent; then rinse
thoroughly with clean water. Repeat if
necessary.
▼ Replacing Windshield Wiper Blades
When the wipers no longer clean well, the
blades are probably worn or cracked.
Replace them.
CAUTION
To prevent damage to the wiper arms and
other components, do not try to sweep the
wiper arm by hand.
NOTE
When raising both windshield wiper arms,
raise the driver's side wiper arm first.
When lowering the wiper arms, slowly
lower the wiper arm from the passenger's
side first while supporting it with your
hand. Forcefully lowering the wiper arms
could damage the wiper arm and blade,
and may scratch or crack the windshield.
1. Raise the wiper arm.
2. Open the clip and slide the blade
assembly in the direction of the arrow.

Wa t e r M a r k s
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.
Paint 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
The 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).
In low temperatures a vehicle's finish
hardens. This increases the chance of
paint chipping.
Chipped 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.

Follow all label and container directions
when using a chemical cleaner or polish.
Read all warnings and cautions.
▼ Maintaining the Finish
Wa s h i n g
CAUTION

When the wiper lever is in the
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 If the windshield above the rain sensor
is touched or wiped with a cloth.
 If the windshield is struck with a hand
or other object from either outside or
inside the vehicle.
Keep hands and scrapers clear of the
windshield when the wiper lever is in the
position and the ignition is
switched ON as fingers could be pinched
or the wipers and wiper blades damaged
when the wipers activate automatically.
If you are going to clean the windshield,
be sure the wipers are turned off
completely (when it is most likely that the
engine is left running) this is particularly
important when clearing ice and snow.
