Switches and Controls
Auto-wiper control
When the wiper lever is in the

position, the rain sensor senses the amount
of rainfall on the windshield and turns the
wipers on or off automatically (off—
intermittent—low speed—high speed).
The sensitivity of the rain sensor can be
adjusted by turning the switch on the
wiper lever.
From the center position (normal), rotate
the switch upward for higher sensitivity
(faster response) or rotate it downward for
less sensitivity (slower response).

CAUTION
 Do not shade the rain sensor by
adhering a sticker or a label on the
windshield. Otherwise the rain sensor
will not operate correctly.

 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.

When Driving
Switches and Controls
NOTE
 Switching the auto-wiper lever from the
to the position while driving
activates the windshield wipers once,
after which they operate according to
the rainfall amount.
 The auto-wiper control may not operate
when the rain sensor temperature is
about -10 °C (14 °F) or lower, or about
85 °C (185 °F) or higher.
 If the windshield is coated with water
repellent, the rain sensor may not be
able to sense the amount of rainfall
correctly and the auto-wiper control
may not operate properly.
 If dirt or foreign matter (such as ice or
matter containing salt water) adheres
to the windshield above the rain sensor,
or if the windshield is iced, it could
cause the wipers to move automatically.
However, if the wipers cannot remove
this ice, dirt or foreign matter, the auto-
wiper control will stop operation. In
this case, set the wiper lever to the low
speed position or high speed position
for manual operation, or remove the ice,
dirt or foreign matter by hand to restore
the auto-wiper operation.
 If the auto-wiper lever is left in the
position, the wipers could operate
automatically from the effect of strong
light sources, electromagnetic waves, or
infrared light because the rain sensor
uses an optical sensor. It is
recommended that the auto-wiper lever
be switched to the
position other
than when driving the vehicle under
rainy conditions.
 The auto-wiper contr ol functions can
be turned off. Refer to Personalization
Features on page 9-9.
Windshield Washer
Pull the lever toward you and hold it to
spray washer fluid.
Washer
OFF
NOTE
If the windshield washer is turned on when
the windshield wipers are not operating,
the windshield wipers operate a few times.
If the washer does not work, inspect the
fluid level (page 6-31). If the fluid level
is normal, consult an Authorized Mazda
Dealer.

Tire Pressure Monitoring System
*Some models.
Tire Pressure Monitoring System*
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all\
four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster \
and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specified
tire pressure (value on the tire pressure label). Follow the procedure\
and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-96.
The warning light flashes when the system has a malfunction.
Refer to Warning Lights on page 4-16.
