▼ Camera and Sensors
Forward Sensing Camera (FSC)
The Forward Sensing Camera (FSC) detects la
ne indications and recognizes headlights,
taillights and city lights during nighttime driv ing. In addition, it also detects the vehicle
ahead, pedestrians, or obstructions. 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)

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 Forward Sensing Camera (FSC) on page 4-235.
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 approaching 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 lined with st reetlamps 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 Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-31.
CAUTION
 Do not adjust the vehicle height, modify th e 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 the 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 sufficient 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 tires
onto your windshield.
▼ To Operate the System
The HBC operates to switch the headlights
automatically between high and low
beams after the igniti
on is switched ON
and the headlight switch is in the AUTO
and high beam position.
The HBC determines that it is dark based
on the brightness of the surrounding area.
At the same time, the HBC indicator light
(green) in the in strument cluster
illuminates.

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 th e Settings section in
the Mazda Connect Owner's Manual.
▼ Manual Switching
Switching to low beams
Shift the lever to th
e low beam position.
