Smart City Brake Support [Forward] (SCBS F)
(Indonesia, Malaysia, and Thailand)
*
The Smart City Brake Support [Forward] (SCBS F) system alerts the driver of a possible
collision using an indication in the display and a warning sound when the Forward Sensing
Camera (FSC) detects a vehicle ahead and determines that a collision with a vehicle ahead
is unavoidable while the vehicle is being driven at a vehicle speed of about 4 to 80 km/h (2
to 50 mph). In addition, the system reduces damage in the event of a collision by operating
the brake control (SCBS brake) when the system determines that a collision is unavoidable
while the vehicle is being driven at a vehicle speed of about 4 to 30 km/h (2 to 18 mph). It
may also be possible to avoid a collision if the relative speed between your vehicle and the
vehicle in front of you is less than about 20 km/h (12 mph). In addition, when the driver
depresses the brake pedal while the system is in the operation range at about 4 to 30 km/h (2
to 18 mph), the brakes are applied ¿ rmly and quickly to assist. (Brake Assist (SCBS brake
assist))

WARNING
Do not rely completely on the Smart City Brake Support [Forward] (SCBS F) system:  
 The Smart City Brake Support [Forward] (SCBS F) 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.
  The Smart City Brake Support [Forward] (SCBS F) is a system which operates
in response to a vehicle ahead. The system may not be able to detect or react to
2-wheeled vehicles or pedestrians.

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.
Refer to Stopping the Smart City Brake Support [Forward] (SCBS F) system Operation
on page 4-169 on how to turn off the Smart City Brake Support [Forward] (SCBS F)
system.

 Under the following conditions, the Smart City Brake Support [Forward] (SCBS F)
system may not operate normally:
 


 The Smart City Brake Support [Forward] (SCBS F) system will not operate if the
driver is deliberately performing driving operations (accelerator pedal and steering
wheel).
 


 If there is the possibility of partial contact with a vehicle ahead.



 The vehicle is driven on a slippery road surface such as wet roads or icy or snow-
bound roads.
 


 The braking performance is adversely affected due to cold temperatures or wet
brakes.
 


 The vehicle is driven at the same speed as the vehicle ahead.



 The accelerator pedal is depressed.



 The brake pedal is depressed.



 The steering wheel is being operated.



 The selector lever is being operated. 

 In the following cases, the Forward Sensing Camera (FSC) determines that there is a
vehicle ahead and the Smart City Brake Support [Forward] (SCBS F) may operate.
 


 Objects on the road at the entrance to a curve.



 Vehicles passing in the opposite lane while making a curve.



 Metal objects, bumps, or protruding objects on the road.



 When passing through a toll gate.



 When passing through low gates, narrow gates, car washing machines, or tunnels.

Smart City Brake Support [Reverse] (SCBS R) *
The Smart City Brake Support [Reverse] (SCBS R) is a system which is designed to reduce
damage in the event of a collision by operating the brake control (SCBS 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.

WARNING
Do not rely completely on the Smart City Brake Support [Reverse] (SCBS R) system:  
 The Smart City Brake Support [Reverse] (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.
  To assure the correct operation of the Smart City Brake Support [Reverse] (SCBS R),
heed the following cautions.
 

 
 Do 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.
 

 
 Do not disassemble an ultrasonic sensor (rear).


 
 If cracks or damage caused by À ying gravel or debris is visible around an ultrasonic
sensor (rear), stop using the Smart City Brake Support [Reverse] (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 4-175 .



 
 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 Smart City Brake Support [Reverse]
(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 Smart City Brake Support [Reverse] (SCBS R) system
to not operate normally, or it could operate unnecessarily.

4–172
When Driving
i-ACTIVSENSE
CAUTION
  When driving off-road in areas where there is grass or foliage, it is recommended that
the Smart City Brake Support [Reverse] (SCBS R) system be turned off.
  Always use tyres of the speci¿ ed size and the same manufacturer, brand, and tread
pattern on all 4 wheels. In addition, do not use tyres with signi¿ cantly different wear
patterns on the same vehicle. Do not use tyres with signi¿ cantly different wear patterns
on the same vehicle. Otherwise, the Smart City Brake Support [Reverse] (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 drive carefully and pay attention to the
rear of the vehicle.
