MAZDA MODEL CX-9 2021 Owners Manual

Smart City Brake Support [Forward] (SCBS F)*
The SCBS F system alerts the driver of a possible collision using an indication in the
display and a warning sound when the Forward Sensing Camera (FSC) detects a vehicle
ahead and determines that a collision with a vehicle ahead is unavoidable while the vehicle
is being driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph). In addition, the
system reduces damage in the event of a collision by operating the brake control (Smart City
Brake Support (SCBS) brake) when the system determines that a collision is unavoidable
while the vehicle is being driven at a vehicle speed of about 4 to 30 km/h (2 to 18 mph). It
may also be possible to avoid a collision if the relative speed between your vehicle and the
vehicle in front of you is less than about 20 km/h (12 mph). In addition, when the driver
depresses the brake pedal while the system is in the operation range at about 4 to 30 km/h (2
to 18 mph), the brakes are applied firmly and quickly to assist. (Brake Assist (Smart City
Brake Support (SCBS) brake assist))

WA R N I N G
Do not rely completely on the SCBS F system:
 The SCBS F system is only designed to red uce damage in the event of a collision. Over
reliance on the system leading to the accel erator pedal or brake pedal being mistakenly
operated could result in an accident.
 The SCBS F is a system which operates in response to a vehicle ahead. The system may not
be able to detect or react to 2-wheeled vehicles or pedestrians.

Smart City Brake Support [Reverse] (SCBS R)*
The SCBS R is a system which is designed to reduce damage in the event of a collision by
operating the brake control (SCBS brake) when the system’s ultrasonic sensors detect an
obstruction at the rear of the vehicle while driving at a speed of about 2 to 8 km/h (2 to 4
mph) and the system determines that a collision is unavoidable.
Reverse Ultrasonic sensor (rear)
WARNING
Do not rely completely on the SCBS R system:

The SCBS R system is only designed to red uce damage in the event of a collision. Over
reliance on the system leading to the accele rator pedal or brake pedal being mistakenly
operated could result in an accident.
 To assure the correct operation of the SCBS R, heed the following cautions.
 Do not apply a sticker to an ultrasonic sens or (rear) (including transparent stickers).
Otherwise, the ultrasonic sensor (rear) may no t be able to detect vehicles or obstructions
which could result in an accident.
 Do not disassemble an ultrasonic sensor (rear).
 If cracks or damage caused by flying gravel or debris is visible around an ultrasonic
sensor (rear), stop using the SCBS R system immediately and have your vehicle inspected
by an Authorized Mazda Dealer. If the vehi cle 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 City Brake Supp ort [Reverse] (SCBS R) System Operation on
page 4-178.

Smart Brake Support(SBS)
*
The SBS system alerts the driver of a
possible collision us ing a display and
warning sound if the radar sensor (front)
and the Forward Sensing Camera (FSC)
determine that there is the possibility of a
collision with a vehicle ahead while the
vehicle is being driven at about 15 km/h or
faster (10 mph or faster). Furthermore, if
the radar sensor (front) and the Forward
Sensing Camera (FSC) determines that 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. (Brake Assist (SBS
brake assist))
WARNING
Do not rely completely on the SBS system
and always drive carefully:
The SBS is designed to reduce damage in
the event of a collision, not avoid an
accident. The ability to detect an
obstruction is limited depending on the
obstruction, weather conditions, or traffic
conditions. Therefore, if the accelerator
pedal or brake pedal is mistakenly
operated it could result in an accident.
Always verify the safety of the surrounding
area and depress the brake pedal or
accelerator pedal while keeping a safer
distance from vehicles ahead or on-coming
vehicles.
CAUTION
