SBS-RC operation
1. The SBS-RC system operates when theshift 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.
WA R N I N G
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, 2-wheeled vehicles, or
animals.
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 4-165.
 Consult an Authorized Mazda Dealer 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.

Mazda3_8HZ1-EA-19G_Edition1_old 2019-5-17 13:49:03

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.
The shift lever (manual transmission
vehicle) or the selector lever
(automatic transmission vehicle) 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.
A large deviation in the installation
position of a rear side radar sensor on
the vehicle has occurred.
There is a large accumulation of snow
or ice on the rear bumper near a rear
side radar sensor.
Driving on snow-covered roads for
long periods.
The temperature near the radar
sensors becomes extremely hot due to
driving for long periods on slopes
during the summer.
The battery voltage has decreased.
Under the following conditions, the rear
side radar sensor cannot detect target
objects or it may be difficult to detect
them.
The rear side radar sensor detection
area is obstructed by a nearby wall or
parked vehicle. (Reverse the vehicle to
a position where the radar sensor
detection area is no longer
obstructed.)
