Smart Brake Support
(SBS)
*
▼Smart Brake Support (SBS)
The SBS alerts the driver of a possible
collision using the warning indications
in the display and a warning sound if
the front radar sensor and Forward
Sensing Camera (FSC) determine that
there is the possibility of a collision
with a vehicle ahead, pedestrian, or a
bicycle. Furthermore, if a collision is
unavoidable, the automatic brake
control is performed to reduce damage
in the event of a collision. In addition,
when the driver depresses the brake
pedal, the brakes are applied firmly
and quickly to assist.
(Vehicles with Driver Monitoring
(DM))
When the SBS determines that the
driver is not paying attention to the
road using the driver monitoring
camera and it determines that there is
the possibility of a collision with an
obstruction, the SBS activates the
collision warning earlier than normal.
WARNING
Do not rely completely on the
SBS:
The SBS is only designed to reduce
damage in the event of a collision.
The ability to detect obstructions is
limited depending on the obstructions,
weather conditions, or
traffic
conditions. Over reliance on the
system leading to the accelerator pedal
or brake pedal being mistakenly
operated could result in an accident.
CAUTION
In the following cases, turn the system
off to prevent an unexpected
operation.
¾The vehicle is being towed or when
towing another vehicle.
¾The vehicle is on a chassis roller.
¾When driving on rough roads such as
in areas of dense grass or off-road.

Smart Brake Support
[Rear Crossing] (SBS-RC)
*
▼Smart Brake Support [Rear
Crossing]
(SBS-RC)
The SBS-RC is a system designed to
assist the driver in avoiding collisions
and to reduce damage in the event of
a collision by applying the brakes if
there is the possibility of collision with
a vehicle approaching from the rear
while you are reversing out of parking
space.
The SBS-RC system detects vehicles
approaching from the rear left and
right sides of the vehicle, and the rear
of the vehicle while the vehicle is being
reversed out of a parking space, the
system reduces damage in the event of
a collision by operating the brake
control when the system determines
that a collision is unavoidable.
SBS-RC operation
1. The SBS-RC system operates when
the shift lever (manual
transmission) or the selector lever
(automatic transmission) is shifted
to the reverse (R) position.
2. If there is the possibility of a
collision with an approaching
vehicle, the SBS-RC system applies
brake and displays “BRAKE!” on the
active driving display and the
multi-information display.
WARNING
Always check the surrounding area
visually before actually putting the
vehicle in reverse:
The system is only designed to assist
you in backing out of the lot when
putting the vehicle in reverse. Due to
certain limitations with the operation
of this system, the SBS-RC system may
not operate brake or it might be
delayed even though a vehicle is
behind your vehicle. Always make it
your responsibility as a driver to check
the rear.
Do not rely completely on the SBS-RC
system:
¾The
SBS-RC system is only designed
to reduce damage in the event of a
collision. Over reliance on the system
leading to the accelerator pedal or
brake pedal being mistakenly
operated could result in an accident.
¾The SBS-RC system operates in
response to a vehicle. The system
does not operate in response to
obstructions such as a wall,
pedestrians, 2-wheeled vehicles, or
animals.
To assure the correct operation of the
SBS-RC, heed the following cautions.
¾Do not apply a sticker to a rear radar
and rear camera. Otherwise, the rear
radar and rear camera may not be
able to detect vehicles or
obstructions which could result in an
accident.
¾Do not disassemble a rear radar and
rear camera.
When Driving
i-ACTIVSENSE
*Some models.4-181

¾If cracks or damage caused by flying
gravel or debris is visible around a
rear radar and rear camera, stop
using the SBS-RC 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 Crossing] (SBS-RC)
System Operation on page 4-184.
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-RC system may not
operate correctly because it cannot
detect obstructions correctly.
Do not apply a strong force to a rear
radar and rear camera:
When washing the vehicle, do not
spray highly pressurised water against a
rear radar 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-RC system to not operate
normally, or it could operate
unnecessarily.
