When Driving
Switches and Controls
Auto-light control
When the headlight switch is in the
position and the ignition is switched ON, the light
sensor senses the surrounding lightness or darkness and automatically turns the headlights,
other exterior lights and instrument panel illumination on or off (see chart above).
CAUTION
  Do not shade the light sensor by adhering a sticker or a label on the windscreen.
Otherwise the light sensor will not operate correctly.

  The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and
scrapers clear of the windscreen when the wiper lever is in the
position and the
ignition is switched ON as fi 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 — this is particularly
important when clearing ice and snow — when it is particularly tempting to leave the
engine running.

Switches and Controls
NOTE
  The headlights, other exterior lights and instrument panel illumination may not turn
off immediately even if the surrounding area becomes well-lit because the light sensor
determines that it is night time if the surrounding area is continuously dark for several
minutes such as inside long tunnels, traffi c jams inside tunnels, or in indoor parking
lots.
 In this case, the lights turn off if the light switch is turned to the position.
  When the headlight switch is in the position and the ignition is switched to ACC
or the ignition is switched off, the headlights, other exterior lights and instrument panel
illumination will turn off.
  The instrument panel illumination can be adjusted by rotating the knob in the
instrument cluster. Also, the antidazzle mode can be changed by rotating the knob until
a beep sound is heard. To adjust the brightness of the instrument panel illumination:
Refer to Instrument panel Illumination on page 4-29 .

 The sensitivity of the AUTO lights may be changed by an Authorised Mazda Repairer.
Refer to Personalisation Features on page 9-13 .

Auto-wiper control
When the wiper lever is in the
position, the rain sensor senses the amount
of rainfall on the windscreen 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 centre position (normal), rotate
the switch downward for higher sensitivity
(faster response) or rotate it upward for
less sensitivity (slower response).

When Driving
Switches and Controls
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 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 fi 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.
NOTE
  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.
  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.

page 9-13 .

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. These
systems consist of active safety and pre-crash safety systems.
These systems are designed to assist the driver in safer driving by reducing the load on the
driver and helping to avert collisions or reduce their severity. However, because each system
has its limitations, always drive carefully and do not rely solely on the systems.
Active Safety Technology
Active Safety Technology supports safer driving by helping the driver to recognise potential
hazards and avert accidents.

Camera and Sensors
Forward sensing camera (FSC)
The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while
travelling at night and detects traffi c lanes. The following systems also use the Forward
Sensing Camera (FSC).
 


 High Beam Control system (HBC)



 Lane Departure Warning System (LDWS)



 Smart Brake Support (SBS)
The Forward Sensing Camera (FSC) is installed at the top of the windscreen near the
rearview mirror.
Refer to Forward Sensing Camera (FSC) on page 4-148 .
Radar sensor (front)
The radar sensor (front) functions by detecting the radio waves refl ected off a vehicle ahead
sent from the radar sensor. The following systems also use the radar sensor (front).
 


 Mazda Radar Cruise Control (MRCC)



 Distance Recognition Support System (DRSS)



 Smart Brake Support (SBS)
The radar sensor (front) is mounted behind the radiator grille.

i-ACTIVSENSE
Laser sensor (front)
The laser sensor (front) emits a near-infrared laser beam and receives the beam refl ected
off the refl ective surface of a vehicle in front, and the detected beam is then used for
measurement. The following systems also use the laser sensor (front).
 


 Smart City Brake Support (SCBS)



 Smart Brake Support (SBS)
The laser sensor (front) is installed at the top of the windscreen near the rearview mirror.
Refer to Laser Sensor (Front) on page 4-154 .
Radar sensors (rear)
The radar sensors (rear) function by detecting the radio waves refl 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 Traffi c Alert (RCTA)
The radar sensors (rear) are installed inside the rear bumper, one each on the left and right
sides.
Refer to Radar Sensors (Rear) on page 4-156 .
