▼Camera and Sensors
Forward Sensing Camera (FSC)
The Forward Sensing Camera (FSC) detects lane indications and r
ecognises headlights, tail
lights and city lights during nighttime driving. In addition, i t also detects the vehicle ahead,
pedestrians, or obstructions. The following systems also use th e Forward Sensing Camera
(FSC).
•High Beam Control System (HBC)
•Adaptive LED Headlights (ALH)
•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 Support [Forward] (SCBS F)
•Smart Brake Support (SBS)
•Mazda Radar Cruise Control with S top & Go function (MRCC with Stop & Go function)

Radar sensor (front)
The radar sensor (front) functions by detecting the radio waves reflected off a vehicle ahead
sent from the radar sensor. The following systems also use the radar sensor (front).
•Mazda Radar Cruise Control with Stop & Go function (MRCC with S top & Go function)
•Mazda Radar Cruise Control (MRCC)
•Distance Recognition Support System (DRSS)
•Smart Brake Support (SBS)
The radar sensor (front) is mount ed behind the radiator grille.
Refer to Radar Sensor (Front) on page 4-201.
Radar sensors (rear)
The radar sensors (rear) function by detecting the radio waves reflected 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)
•Rear Cross Traffic 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 4-204.
Ultrasonic sensors (rear)
The ultrasonic sensors (rear) function by detecting the ultraso nic waves reflected off
obstructions at the rear sent fro m the ultrasonic sensors. The following systems also use the
ultrasonic sensors (rear).

Adaptive Front LightingSystem (AFS)
*
The adaptive front lighting system (AFS)
automatically adjusts the headlight beams
to the left or right i n conjunction with the
operation of the steering wheel after the
headlights have been turned on.
NOTE
•Headlights do not blind drivers
approaching in the opposite direction no
matter what side of the road you must
drive your vehicle (left-hand or
right-hand traffic). Therefore, it is not
necessary to adjust the optical axis of
the headlights when switching
temporarily to driving on the opposite
side of the road (left-hand or right-hand
traffic).
•The Adaptive Front Lighting System
(AFS) function can be switched to
operable/inoperable using the
personalisation function.
Refer to Personalisation Features on
page 9-12.

High Beam Control System (HBC)*
The HBC determines the conditions in front of the vehicle using the Forward Sensing
Camera (FSC) while driving in darkness to automatically switch the headlights between
high and low beams.
Refer to Warning/Indicator Lights on page 4-42.
While driving the vehicle at a speed of about 30 km/h (19 mph) or more, the headlights are
switched to high beams when there are no vehicles ahead or appr oaching in the opposite
direction.
The system switches the headlights to low beams when one of the following occurs:
•The system detects a vehicle or the headlights/lights of a vehicle approaching in the
opposite direction.
•The vehicle is driven on roads lin ed with streetlamps or on roads in well-lit cities and
towns.
•The vehicle is driven at less than about 20 km/h (12 mph).
Forward Sensing
Camera (FSC)
The recognition distance of the
Forward Sensing Camera (FSC)
varies according to the
surrounding conditions.
The warning light turns on when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-42.
CAUTION
Do not adjust the vehicle he ight, modify the headlight units, or remove the camera,
otherwise the system will not operate normally.
Do not rely excessively on the HBC and drive the vehicle while paying
sufficient attention to
safety. Switch the headlights between th e high beams and low beams manually if
necessary.

NOTE
The timing in which the system switches the headlights changes under the following
conditions. If the system does not switch the headlights appropriately, manually switch
between high and low beams according to the visibility as well as road and traffic
conditions.
•When there are sources of light in the area such as street lamps, illuminated signboards,
and traffic signals.
•When there are reflective objects in the surrounding area such as reflective plates and
signs.
•When visibility is reduced under rain, snow and foggy conditions.
•When driving on roads with sharp turn or hilly terrain.
•When the headlights/rear lamps of vehicles in front of you or in the opposite lane are dim
or not illuminated.
•When there is insufficient darkness such as at dawn or dusk.
•When the luggage compartment is loaded with heavy objects or the rear passenger seats
are occupied.
•When visibility is reduced due to a vehicle in front of you spraying water from its tyres
onto your windscreen.
▼ To Operate the System
The HBC operates to sw
itch the headlights
automatically between high and low
beams after the ignition is switched ON
and the headlight switch is in the AUTO
and high beam position.
The HBC determines t hat it is dark based
on the brightness of the surrounding area.
At the same time, th e HBC indicator light
(green) in the instrument cluster
illuminates.
The HBC determines t hat it is dark based
on the brightness of the surrounding area.
NOTE
•When the vehicle speed is about 30 km/h
(19 mph) or more, the headlights
automatically switch to high beams
when there are no vehicles ahead or
approaching in the opposite direction.
When the vehicle speed is less than
about 20 km/h (12 mph), the HBC
switches the headlights to low beams.
•The low beams may not switch to high
beams when cornering.
•Operation of the HBC function can be
disabled. Refer to Personalisation
Features on page 9-12.

Adaptive LED Headlights (ALH)*
The ALH are a system which uses the Forward Sensing Camera (FSC) to determine the
situation of a vehicle ahead or a vehicle approaching in the op posite direction while driving
at night to automatically switc h the illumination range of the headlights, the illuminated
area, or the illumination brightness.
Refer to Forward Sensing Camera (FSC) on page 4-196.
The ALH are controlled between high and low beams as follows to assure the driver’s
visibility without dazzling a ve hicle ahead or a vehicle approaching in the opposite
direction.
Glare-Free High Beam
This feature dims only the high-beam light shone on the vehicle ahead.
The high beams will dim while driving at a speed of about 40 km /h (25 mph) or faster.
When the vehicle speed is less than about 30 km/h (18 mph), the beams switch to the low
beams.
NOTE
The headlight high-beam indicator light turns on while the high beams are on.

Wide-Range Low Beam
This feature extends the illumination range of the light cast by the low beams while driving
at a speed less than about 40 km/h (25 mph).
Highway Mode
This feature shifts the illumina tion angle of the light cast by the headlights upward while
driving on highways.
The distance in which the ALH can detect objects varies depending on the surrounding
conditions.
CAUTION
Do not modify the suspensions or headlight units, or remove the camera. Otherwise, the
ALH may not operate normally.
Do not rely excessively on the ALH and drive the vehicle while paying sufficient attention to
safety. Switch the headlights between th e high beams and low beams manually if
necessary.
NOTE
Under the following conditions, the ALH may not operate normally. Manually switch
between the high and low beams according to the visibility, and the road and traffic
conditions.
•When there are other sources of light in the area such as street lamps, illuminated
signboards, and traffic signals.
•When there are reflective objects in the surrounding area such as reflective plates and
signs.
