Mazda Radar Cruise Control with Stop & Go function
(MRCC with Stop & Go functi on) (Automatic Transaxle
except Taiwan)
*
The MRCC with Stop & Go function system is designed to maintain headway control*1
with a vehicle ahead according to your vehicle's speed using a radar sensor (front) to detect
the distance to the vehicle ahead and a preset vehicle speed without you having to use the
accelerator or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and the vehicle ahead
detected by the Mazda Radar Cr uise Control (MRCC) system.
Additionally, if your vehicle s tarts closing in on the vehicle ahead such as if the vehicle
ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a sufficient distance between the vehicles.
If the vehicle ahead stops while you are following behind it, your vehicle will stop and be
held stopped automatically (stop hold control), and headway con trol will resume when you
resume driving the vehicle such a s by pressing the RES switch.
Also refer to the following before using the MRCC with Stop & G o function.
•i-stop (page 4-12)
•AUTOHOLD (page 4-84)
•Forward Sensing Camera (FSC) (page 4-196)
•Radar sensor (front) (page 4-201)
WA R N I N G
Do not rely completely on the MRCC with Stop & Go function:
The MRCC with Stop & Go function system has detection limitations depending on the type of
vehicle ahead and its conditions, the weat her conditions, and the road conditions.
Additionally, the system may be unable to decelerate sufficiently to avoid hitting the vehicle
ahead if the vehicle ahead applies the brakes sudd enly or another vehicle cuts into the driving
lane, which could result in an accident.
Always drive carefully and verify the surrounding conditions and depress the brake pedal or
accelerator pedal while keeping a safer distance from vehicles ahead or on-coming vehicles.
Do not use the MRCC with Stop & Go function system in the following locations, using the
MRCC with Stop & Go function system at the following locations may result in an unexpected
accident:
 General roads other than highways (Driving under these conditions using the MRCC with
Stop & Go function system is not possible.)

•When accelerating using the SET
switch while in headway control, the set
vehicle speed can be adjusted but
acceleration is not possible. If there is
no longer a vehicle ahead, acceleration
continues until reaching the set vehicle
speed. For the set vehicle speed, check
the set vehicle speed indication in the
display.
•When depressing the accelerator pedal,
the inter-vehicle distance indication in
the display changes to the white-line
indication.
•(European models)
When switching to a passing lane and
operating the direction indicator, the
system provides more acceleration
automatically if it determines that more
acceleration is required. Drive while
being careful of the road ahead because
you could approach the vehicle ahead
too closely.

Smart City Brake Support [Reverse] (SCBS R)*
The SCBS R is a system which is designed to reduce damage in the event of a collision by
operating the brake control (SCB S brake) when the system’s ultrasonic sensors detect an
obstruction at the rear of the vehicle while driving at a speed of about 2 to 8 km/h (2 to 4
mph) and the system determines that a collision is unavoidable.
Reverse Ultrasonic sensor (rear)
WA R N I N G
Do not rely completely on the SCBS R system:

The SCBS R system is only designed to red uce damage in the event of a collision. Over
reliance on the system leading to the accele rator pedal or brake pedal being mistakenly
operated could result in an accident.
 To assure the correct operation of the SCBS R, heed the following cautions.
 Do not apply a sticker to an ultrasonic sens or (rear) (including transparent stickers).
Otherwise, the ultrasonic sensor (rear) may no t be able to detect vehicles or obstructions
which could result in an accident.
 Do not disassemble an ultrasonic sensor (rear).
 If 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 Au thorised Mazda Repairer. If the vehicle
continues to be driven with cracks or scratch marks left around an ultrasonic sensor, the
system may operate unnecessarily an d cause an unexpected accident.
Refer to Stopping the Smart City Brake Supp ort [Reverse] (SCBS R) System Operation on
page 4-192.
 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 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 no t detect obstructions correctly which could
cause the SCBS R system to not operate no rmally, or it could operate unnecessarily.
CAUTION
When driving
off-road in areas where there is grass or foliage, it is recommended that the
SCBS R system be turned off.
 Always use tyres of the specified size and th e same manufacturer, brand, and tread pattern
on all 4 wheels. In addition, do not use tyres wi th significantly different wear patterns on the
same vehicle. Otherwise, the SCBS R system may not operate normally.
 If 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 dr ive 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 SCBS R may or
may not operate.
•The SCBS R system will operate under the following conditions.
•The engine is running.
•The change lever (manual transaxle vehicle) or the selector lever (automatic transaxle
vehicle) is in the R (reverse) position.

•The vehicle speed is between about 2 to 8 km/h (2 to 4 mph).
•The SCBS R is not turned off.
•The DSC is not malfunctioning.
•The 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.
•In the following cases, the ultrasonic sensors (rear) cannot detect obstructions and the
SCBS R may not operate.
•The height of the obstruction is low such as low walls or trucks with low loading
platforms.

Smart Brake Support (SBS)*
The SBS system alerts the driver of a possible collision using a display and warning sound
if the radar sensor (front) and the Forward Sens ing Camera (FSC) determine that there is the
possibility of a collision with a vehicle ahead while the vehicle is being driven at about 15
km/h or faster (10 mph or faster). Furthermore, if the radar se nsor (front) and the Forward
Sensing Camera (FSC) determines that a collision is unavoidable, the automatic brake
control is performed to reduce d amage in the event of a collision.
In addition, when the driver depresses the brake pedal, the bra kes are applied firmly and
quickly to assist. (Brake Assist (SBS brake assist))
WA R N I N G
Do not rely completely on the SBS system and always drive carefully:
The SBS is designed to reduce damage in the ev ent of a collision, not avoid an accident. The
ability to detect an obstruction is limited de pending on the obstruction, weather conditions,
or traffic conditions. Therefore, if the accelerator pe
dal or brake pedal is mistakenly operated
it could result in an accident. Always verify th e safety of the surrounding area and depress the
brake pedal or accelerator pedal while keepin g a safer distance from vehicles ahead or
on-coming vehicles.
CAUTION
In the following cases, turn the system off to prevent a mis-operation:
 The vehicle is being towed or when towing another vehicle.
 The vehicle is on a chassis roller.
 When driving on rough roads such as in areas of dense grass or
off-road.
NOTE
•The SBS system operates when all of the following conditions are met:
