Do not apply a sticker to a rear
ultrasonic sensor and rear camera.
Otherwise, the rear ultrasonic
sensor and rear camera may not be
able to detect vehicles or
obstructions which could result in
an accident.
Do not disassemble a rear
ultrasonic sensor and rear camera.
If cracks or damage caused by
flying gravel or debris is visible
around a rear ultrasonic sensor and
rear camera, stop using the SBS-R
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] (SBS-R) System
Operation on page 4-179.
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-R system may not
operate correctly because it cannot
detect obstructions correctly.
Do not apply a strong force to a rear
ultrasonic sensor and rear camera:
When washing the vehicle, do not
spray highly pressurised 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 tyres of the specified size
and the same manufacturer, brand,
and tread pattern on all 4 wheels. In
addition, do not use tyres 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 recognise
an obstruction, or it could facilitate
unnecessary detection. In such cases,
the SBS-R may or may not operate.
