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, 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 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 4-174.
Consult 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.
