Do not use the cruise control function in
the following locations:
Otherwise, it could lead to an accident.
¾Roads with sharp curves and where
vehicle
traffic is heavy and there is
insufficient space between vehicles.
(Driving under these conditions using the
cruise control function is not possible)
¾Steep down slopes (Set speed may be
exceeded because sufficient engine
braking cannot be applied)
¾Slippery roads such as ice or snow-bound
roads (Tyres could spin causing you to
lose vehicle control)
Always drive carefully:
The warnings and brake control will not
operate after the headway control function
is cancelled and the system is switched to
only the cruise control function. Depress
the brake pedal to decelerate according to
the surrounding conditions while keeping a
safer distance from the vehicle ahead and
always driving carefully.

Always turn off the cruise control function
when it is not in use:
Leaving the cruise control function turned
on when it is not in use is dangerous as it
could operate unexpectedly, resulting in an
accident.

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.

xWhen the cruise control system is
temporarily cancelled by even one of the
applicable cancel conditions, the speed
cannot be re-set.
x(Automatic transaxle)
The cruise control cannot be cancelled
while driving in manual mode (selector
lever shifted from D to M position).
Therefore, engine braking will not be
applied even if the transaxle is shifted
down to a lower gear. If deceleration is
required, lower the set speed or depress
the brake pedal.

xUnder extremely hot or cold weather conditions.
xThe vehicle is driven on bumps, inclines, gravel, or grass covered roads.
xAnything which generates ultrasound is near the vehicle, such as another vehicle's
horn, the engine sound of a motorcycle, the air brake sound of a large-sized vehicle, or
another vehicle's sensors.
xThe vehicle is driven in heavy rain or in road conditions causing water-splash.
xA commercially-available wing pole or an aerial for a radio transmitter is installed to
the vehicle.
xThe vehicle is moving towards a tall or square curbstone.
xAn obstruction is too close to the sensor.
xObstructions under the bumper may not be detected. Obstructions that are lower than the
bumper or thin which may have been initially detected may no longer be detected as the
vehicle approaches more closely to the obstruction.
xThe following types of obstructions may not be detected:
xThin objects such as wire or rope
xThings which absorb sonic waves easily such as cotton or snow
xAngular shaped objects
xVery tall objects, and those which are wide at the top
xSmall, short objects
xAlways have the system inspected at an expert repairer (we recommend an Authorised
Mazda Repairer) if any shock is applied to the bumpers, even in a minor accident. If the
sensors are deviated, they cannot detect obstructions.
x(With front sensor and front corner sensor)
The system may have a malfunction if the beep does not operate or the indicator light
does not illuminate when the park assist sensors switch is turned on. Consult an expert
repairer (we recommend an Authorised Mazda Repairer).
x(Without front sensor and front corner sensor)
The system may have a malfunction if the beep does not operate. Consult an expert
repairer (we recommend an Authorised Mazda Repairer).
x(With front sensor and front corner sensor)
The system may have a malfunction if the beep sound which indicates a system
malfunction is heard and the indicator light flashes. Consult an expert repairer (we
recommend an Authorised Mazda Repairer).
xThe beeper which indicates a system malfunction may not be heard if the ambient
temperature is extremely cold, or mud, ice, or snow adheres to the sensor area. Remove
any foreign material from the sensor area.
