Switches and Controls
CAUTION
Do not shade the rain sensor by
adhering a sticker or a label on the
windscreen. 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 windscreen above the rain
sensor is touched or wiped with a
cloth.
If the windscreen is struck with a
hand or other object from either
outside or inside the vehicle.
Keep hands and scrapers clear of the
windscreen when the wiper lever is
in the
position and the ignition
is switched ON as ¿ ngers could be
pinched or the wipers and wiper
blades damaged when the wipers
activate automatically.
If you are going to clean the
windscreen, 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.
NOTE
Switching the auto-wiper lever from
the
to the position while
driving activates the windscreen
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 windscreen is coated with
water repellent, the rain sensor may
not be able to sense the amount of
rainfall correctly and auto-wiper
control may not operate properly.
If dirt or foreign matter (Such as
ice or matter containing salt water)
adheres to the windscreen above
the rain sensor or if the windscreen
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.

When Driving
Switches and Controls
NOTE
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 control functions can
be turned off.
Refer to Personalisation Features on
page 9-10 .
Windscreen Washer
Pull the lever toward you and hold it to
spray washer À uid.
Washer OFF
NOTE
If the windscreen washer is turned
on when the windscreen wipers are
not operating, the windscreen wipers
operate a few times.
If the washer does not work, inspect the
À uid level (page 6-23 ). If the À uid level
is normal, consult an expert repairer,
we recommend an Authorised Mazda
Repairer.
NOTE
(With headlight washers)
When the headlights are on, the
headlight washers operate automatically
once every ¿ fth time the windscreen
washer operates.

i-ACTIVSENSE *
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forward Sensing Camera (FSC) and radar sensors.
Because each system has its limitations, always drive carefully and do not rely solely on the
systems.

Radar sensors (rear)
The radar sensors (rear) function by detecting the radio waves re À ected off a vehicle
approaching from the rear or an obstruction sent from the radar sensors. The following
systems also use the radar sensors (rear).
Blind Spot Monitoring (BSM) System
Rear Cross Traf ¿ c Alert (RCTA)
The radar sensors (rear) are installed inside the rear bumper, one each on the left and right
sides.
