When the headlight switch is in t he AUTO position and the ignition is switched ON, the
light sensor senses the surrounding lightness or darkness and automatically turns the
headlights and other exterior lights on or off.

CAUTION
Do not shade the light sensor by adhering a st icker or a label on the windshield. 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 windshield when the wiper lever is in the AUTO position and the
ignition is switched ON as fingers could be pinched or the wipers and wiper blades could be
damaged when the wipers activate automaticall y. If you are going to clean the windshield,
be sure the wipers are turned off completely wh en it is particularly tempting to leave the
engine running. This is particularly important when clearing ice and snow.
NOTE
The headlights and other exterior lights 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, traffic jams inside tunnels, or in indoor parking lots.
In this case, the lights turn off if the li ght switch is turned to the OFF position.
If the headlight switch and the windshield wiper switch are in AUTO, and the wipers are
operated at low or high speed by the auto wiper control for several seconds, bad weather
conditions are determined and the headlights may be turned on.
The sensitivity of the auto-light control may be changed.
Refer to the Settings section in the Mazda Connect Owner's Manual.

When the wiper lever is in the AUTO
position, the rain sen sor 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).

When the ignition is switched ON and
the wiper lever is in the AUTO position,
the windshield wipers may operate
automatically in the following cases:
 The area of the windshield above the
rain sensor is touched or wiped with a
cloth.
 The windshield or the rain sensor area
in the cabin is hit.
When the ignition is switched ON and
the wiper lever is in the AUTO position,
do not touch the windshield or the
windshield wipers Otherwise, the
windshield wipers will operate
automatically which could catch your
fingers or damage the windshield wipers.
When removing ice or snow, or cleaning
the windshield, always make sure the
wiper lever is in the OFF position.
NOTE
Switching the auto-wip er lever from the
OFF to the AUTO position while driving
activates the windshield wipers once,
after which they ope rate 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 wi ll 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
AUTO 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 OFF position other
than when driving the vehicle under
rainy conditions.
(With auto-wiper control (Except
Canada))
If the headlight switch and the
windshield wiper switch are in AUTO,
and the wipers are operated at low or
high speed by the auto wiper control for
several seconds, bad weather conditions
are determined and the headlights may
be turned on.
The auto-wiper control functions can be
turned off. Refer to the Settings section
in the Mazda Connect Owner's Manual.

i-ACTIVSENSE*
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forw ard Sensing Camera (FSC) and radar sensors. These
systems consist of active safety and pre-crash safety systems.
These systems are designed to ass ist the driver in safer driving by reducing the load on the
driver and helping to avert col lisions or reduce their severity. However, because each system
has its limitations, always drive carefully and do not rely sol ely on the systems.
▼Active Safety Technology
Active Safety Technology supports safer driving by helping the
driver to recognize potential
hazards and avert accidents.

ahead, pedestrians, or obstructi ons. The following systems also use the Forward Sensing
Camera (FSC).
High Beam Control System (HBC)
Driver Attention Alert (DAA)
Lane-keep Assist System (LAS) & Lane Departure Warning System ( LDWS)
Traffic Sign Recognition System (TSR)
Advanced Smart City Brake Support (Advanced SCBS)
Smart City Brake Suppo rt [Forward] (SCBS F)

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)
Rear Cross Traffic Alert (RCTA)
The radar sensors (rear) are inst alled inside the rear bumper, one each on the left and right
sides.
Refer to Radar S ensors (Rear) on page 4-247.
Ultrasonic sensors (rear)
The ultrasonic sensors (rear) function by detecting the ultraso nic waves reflected off
obstructions at the rear sent from the ultrasonic sensors. The following systems also use the
ultrasonic sensors (rear).
Smart City Brake Suppor t [Reverse] (SCBS R)
The ultrasonic sensors (rear) are mounted in the rear bumper.
Refer to Ultrasonic Sens ors (Rear) on page 4-249.
Front camera/side cameras/rear view camera
The front camera, side cameras, and rear camera shoot images of the area surrounding the
vehicle. The 360° View Monitor uses each camera.
