*
▼ Smart Brake Support [Rear]
(SBS
-R)
The SBS -R is a system which is
designed to reduce damage in the
event of a collision by operating the
brake control (SBS brake) when the
system’s 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.
WARNING
Do not rely completely on the SBS -R
system:
 The
SBS-R 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.
 To assure the correct operation of
the SBS -R, heed the following
cautions.

NOTE
The vehicle posture changes
depending on the accelerator pedal,
brake pedal and steering wheel
operations, which could make itdi fficult for the system to recognize
an obstruction, or it could facilitate
unnecessary detection. In such cases,
the SBS -R may or may not operate.
The SBS -R system will operate under
the following conditions.
The engine is running for 3 seconds
or more.

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:
 The
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.
 The
SBS-RC system operates in
response to a vehicle. The system
does not operate in response to
obstructions such as a wall,
pedestrians, or animals.
When Driving
i-ACTIVSENSE
4-164*Some models.
Mazda3_8JM2-EA -20H_Edition1_new 2020-7-10 17:21:34

To assure the correct operation of the
SBS-RC, heed the following cautions.
 Do 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.
 Do not disassemble a rear radar and
rear camera.
 If 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 Authorized Mazda
Dealer. 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 4-168.
 Consult an Authorized Mazda Dealer
for rear bumper removal.
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 pressurized 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.
NOTE
The SBS -RC system will operate
under the following conditions.
The engine is running for 3 seconds
or more.
The shift lever (manual
transmission ve hicle) or the
selector lever (automatic
transmission vehicl e) is in the R
(reverse) position.
i-ACTIVSENSE warning indication/
warning light is not displayed in the
multi-information display.
The vehicle speed is under about
10 km/h (6 mph).
The vehicle speed of an
approaching vehicle is about 3
km/h (2 mph) or faster.
The SBS-R is not turned
off.The DSC is not malfunctioning.In the following cases, the
i-ACTIVSENSE warning indication/
warning light turns on and operation
of the system is stopped. If the
i-ACTIVSENSE warning indication/
warning light remains illuminated,
have the vehicle inspected at an
Authorized Mazda Dealer as soon as
possible.
Some problem with the system
including the SBS -RC system.

Tu r n off the SBS-RC system while
pulling a trailer or while an accessory
such as a bicycle carrier is installed to
the rear of the vehicle. Otherwise,
the radio waves emitted by the radar
will be blocked causing the system to
not operate normally.
In the following cases, a rear radar
and rear camera may detect
something as a target obstruction
which could cause the SBS -RC
system to operate.
There are hanging curtains, gate
poles such as at toll gates and
railroad crossing.
When traveling near objects such
as foliage, barriers, vehicles, walls,
