High Beam Control
System (HBC)
*
▼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 4-216.
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:
xThe system detects a vehicle or the
headlights/lights of a vehicle
approaching in the opposite
direction.
xThe vehicle is driven on roads lined
with streetlamps or on roads in
well-lit cities and towns.
xThe vehicle is driven at less than
about 20 km/h (12 mph).
xThe headlight high-beam indicator
light turns on while the high beams
are on.
1. Forward Sensing Camera (FSC)*1
*1 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 High Beam Control System
(HBC) Warning Indication/Warning
Light (Amber) on page 7-58.
CAUTION
¾Do not adjust the vehicle height,
modify the headlight units, or
remove the camera, otherwise the
system will not operate normally.
¾Do 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.
xWhen there are sources of light in
the area such as street lamps,
illuminated signboards, and traffic
signals.
xWhen there are reflective objects in
the surrounding area such as
reflective plates and signs.
xWhen visibility is reduced under rain,
snow and foggy conditions.
xWhen driving on roads with sharp
turn or hilly terrain.
xWhen the headlights/rear lamps of
vehicles in front of you or in the
opposite lane are dim or not
illuminated.

¾Do not apply a sticker to a rear
ultrasonic sensor and rear camera.
Otherwise, the rear ultrasonic
sensor and rear camera may not be
able to detect vehicles or
obstructions which could result in
an accident.
¾Do not disassemble a rear
ultrasonic sensor and rear camera.
¾If cracks or damage caused by
flying gravel or debris is visible
around a rear ultrasonic sensor and
rear camera, stop using the SBS-R
system immediately and have your
vehicle inspected by an expert
repairer (we recommend an
Authorised Mazda Repairer). If the
vehicle continues to be driven with
cracks or scratch marks left around
an ultrasonic sensor, the system
may operate unnecessarily and
cause an unexpected accident.
Refer to Stopping the Smart Brake
Support [Rear] (SBS-R) System
Operation on page 4-180.
¾Consult an expert repairer (we
recommend an Authorised Mazda
Repairer) for rear bumper
replacement.
Do not modify the suspension:
If the vehicle height or inclination is
changed, the SBS-R system may not
operate correctly because it cannot
detect obstructions correctly.
Do not apply a strong force to a rear
ultrasonic sensor and rear camera:When washing the vehicle, do not
spray highly pressurised water against a
rear ultrasonic sensor and rear camera,
or rub it strongly. In addition, do not
hit the rear bumper forcefully when
loading and unloading cargo.
Otherwise, the sensors may not detect
obstructions correctly which could
cause the SBS-R system to not operate
normally, or it could operate
unnecessarily.
CAUTION
¾When driving off-road in areas where
there is grass or foliage, it is
recommended that the SBS-R system
be turned off.
¾Always use tyres of the specified size
and the same manufacturer, brand,
and tread pattern on all 4 wheels. In
addition, do not use tyres with
significantly different wear patterns
on the same vehicle. Otherwise, the
SBS-R system may not operate
normally.
¾If ice or snow is stuck on the rear
ultrasonic sensor and rear camera
they may not be able to detect
obstructions correctly depending on
the conditions. In such cases, the
system may not be able to perform
controls correctly. Always drive
carefully and pay attention to the
rear of the vehicle.
NOTE
xThe vehicle posture changes
depending on the accelerator pedal,
brake pedal and steering wheel
operations, which could make it
difficult for the system to recognise
an obstruction, or it could facilitate
unnecessary detection. In such cases,
the
SBS-R may or may not operate.
