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

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.
