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 4-164.
 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.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
