Do not apply a strong force to a rear
ultrasonic sensor and rear camera:
When washing the vehicle, do not spray
highly pressurized water against a rear
ultrasonic sensor 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-R system to not
operate normally, or it could operate
unnecessarily.
CAUTION
When driving
off-road in areas where
there is grass or foliage, it is
recommended that the SBS-R system be
turned off.
 Always use tires of the specified size and
the same manufacturer, brand, and
tread pattern on all 4 wheels. In addition,
do not use tires with significantly
different wear patterns on the same
vehicle. Otherwise, the SBS-R system may
not operate normally.
 If ice or snow is stuck on the rear
ultrasonic sensor and rear camera they
may not be able to detect obstructions
correctly depending on the conditions. In
such cases, the system may not be able
to perform controls correctly. Always
drive carefully and pay attention to the
rear of the vehicle.
NOTE
The vehicle posture changes depending
on the accelerator pedal, brake pedal
and steering wheel operations, which
could make it difficult for the system to
recognize an obstruction, or it could
facilitate unnecessary detection. In such
cases, the SBS-R may or may not
operate.

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.

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
