Do not rely completely on the SCBS R system:
¾The SCBS R 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.
¾To assure the correct operation of the SCBS R, heed the following cautions.
¾Do not apply a sticker to an ultrasonic sensor (rear) (including transparent stickers).
Otherwise, the ultrasonic sensor (rear) may not be able to detect vehicles or obstructions
which could result in an accident.
¾Do not disassemble an ultrasonic sensor (rear).
¾If cracks or damage caused by flying gravel or debris is visible around an ultrasonic
sensor (rear), stop using the SCBS 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 City Brake Support [Reverse] (SCBS R) System Operation on
page 4-176.
¾Consult 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 SCBS R system may not operate correctly
because it cannot detect obstructions correctly.
Do not apply a strong force to an ultrasonic sensor (rear):
When washing the vehicle, do not spray highly pressurised water against an ultrasonic sensor
(rear), 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 SCBS R system to not operate normally, or it could operate unnecessarily.
& $ 8 7 , 2 1
¾When driving off-road in areas where there is grass or foliage, it is recommended that the
SCBS R system be turned off.
¾Always 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 SCBS R system may not operate normally.

¾If ice or snow is stuck on the ultrasonic sensors (rear) 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
xThe 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 SCBS R may or
may not operate.
xThe SCBS R system will operate under the following conditions.
xThe Smart City Brake Support (SCBS) warning light (amber) does not illuminate.
xThe engine is running.
xThe change lever (manual transaxle vehicle) or the selector lever (automatic transaxle
vehicle) is in the R (reverse) position.
xThe vehicle speed is between about 2 to 8 km/h (2 to 4 mph).
xThe SCBS R is not turned off.
xThe DSC is not malfunctioning.
xThe SCBS R operates using ultrasonic sensors (rear) which detect obstructions at the rear
by emitting ultrasonic waves and then receiving the returning waves reflected off the
obstructions.
xIn the following cases, the ultrasonic sensors (rear) cannot detect obstructions and the
SCBS R may not operate.
xThe height of the obstruction is low such as low walls or trucks with low loading
platforms.
xThe height of the obstruction is high such as trucks with high loading platforms.
xThe obstruction is small.
xThe obstruction is thin such as a signpost.
xThe obstruction is positioned away from the centre of the vehicle.
xThe surface of the obstruction is not pointed vertically relative to the vehicle.
xThe obstruction is soft such as a hanging curtain or snow stuck to a vehicle.
xThe obstruction is shaped irregularly.
xThe obstruction is extremely close.

xIn the following cases, the ultrasonic sensors (rear) cannot detect obstructions correctly
and the SCBS R may not operate.
xSomething is stuck on the bumper near an ultrasonic sensor (rear).
xThe steering wheel is turned sharply, or the brake or accelerator pedal is operated.
xThere is another obstruction near one obstruction.
xDuring inclement weather such as rain, fog and snow.
xHigh or low humidity.
xHigh or low temperatures
xStrong winds.
xThe path of travel is not flat.
xHeavy luggage is loaded in the luggage compartment or on the rear seat.
xObjects such as a wireless aerial, fog light, or illuminated number plate is installed
near an ultrasonic sensor (rear).
xThe orientation of an ultrasonic sensor (rear) has deviated for reasons such as a
collision.
xThe vehicle is affected by other sound waves such as the horn, engine noise, ultrasonic
sensor of another vehicle.
xIn the following cases, an ultrasonic sensor (rear) may detect something as a target
obstruction which could cause the SCBS R system to operate.
xDriving on a steep slope.
xWheel blocks.
xHanging curtains, gate poles such as at toll gates and railroad crossing.
xWhen travelling near objects such as foliage, barriers, vehicles, walls, and fences along
a road.
xWhen driving off-road in areas where there is grass and forage.
xWhen passing through low gates, narrow gates, car washing machines, and tunnels.
xA towing bar is installed or a trailer is connected.
x(Manual transaxle)
If the vehicle is stopped by the Smart City Brake Support (SCBS) operation and the clutch
pedal is not depressed, the engine stops.
xThe Smart City Brake Support (SCBS) warning indication (amber) turns on when the
system has a malfunction.
Refer to Warning Lights on page 4-39.

Do not rely completely on the SBS system
and always drive carefully:
The SBS is designed to reduce damage in
the event of a collision, not avoid an
accident. The ability to detect an
obstruction is limited depending on the
obstruction, weather conditions, or traffic
conditions. Therefore, if the accelerator
pedal or brake pedal is mistakenly
operated it could result in an accident.
Always verify the safety of the surrounding
area and depress the brake pedal or
accelerator pedal while keeping a safer
distance from vehicles ahead or on-coming
vehicles.
& $ 8 7 , 2 1
In the following cases, turn the system off
to prevent a mis-operation:
¾The vehicle is being towed or when
towing another vehicle.
¾The vehicle is on a chassis roller.
¾When driving on rough roads such as in
areas of dense grass or off-road.
NOTE
xThe SBS system operates when all of the
following conditions are met:
xThe ignition is switched ON.
xThe SBS system is on.
xThe vehicle speed is about 15 km/h or
faster (10 mph or faster).
xThe relative speed between your
vehicle and the vehicle ahead is about
15 km/h or faster (10 mph or faster).
xThe Dynamic Stability Control (DSC)
is not operating.
xThe SBS system may not operate under
the following conditions:
xIf the vehicle is accelerated rapidly
and it comes close to a vehicle ahead.
xThe vehicle is driven at the same
speed as the vehicle ahead.
xThe accelerator pedal is depressed.
xThe brake pedal is depressed.
xThe steering wheel is being operated.
xThe selector lever is being operated.
xThe direction indicator is being used.
xWhen the vehicle ahead is not
equipped with tail lights or the tail
lights are turned off.

xWhen warnings and messages, such
as a dirty windscreen, related to the
Forward Sensing Camera (FSC) are
being displayed in the centre display.
xAlthough the objects which activate the
system are four-wheeled vehicles, the
radar sensor (front) could detect the
following objects, determine them to be
an obstruction, and operate the SBS
system.
xObjects on the road at the entrance to
a curve (including guardrails and
snow banks).
xA vehicle appears in the opposite lane
while cornering or rounding a curve.
xWhen crossing a narrow bridge.
xWhen passing under a low gate or
through a tunnel or narrow gate.
xWhen entering an underground
parking area.
xMetal objects, bumps, or protruding
objects on the road.
xIf you suddenly come close to a
vehicle ahead.
xWhen driving in areas where there is
high grass or forage.
xTwo-wheeled vehicles such as
motorbikes or bicycles.
xPedestrians or non-metallic objects
such as standing trees.
xWhen the system operates, the user is
notified by the active driving display.
xThe SBS warning indication (amber)
turns on when the system has a
malfunction.
