Smart City Brake Support [Forward] (SCBS F) *
The Smart City Brake Support (SCBS) system is designed to reduce damage in the event
of a collision by operating the brake control (SCBS brake) when the system's laser sensor
detects a vehicle ahead and determines that a collision with a vehicle ahead is unavoidable.
It may also be possible to avoid a collision if the relative speed between your vehicle and a
vehicle ahead 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))

i-ACTIVSENSE
WARNING
Do not rely on the Smart City Brake Support System (SCBS) as a substitute for safer
driving:
The Smart City Brake Support (SCBS) system cannot compensate for unsafe and
reckless driving, excessive speed, tailgating (following another vehicle too closely), and
driving on slippery roads such as wet, snowy, and icy roads (reduced tyre friction and
road contact because of water on the road surface). You can still have an accident.

Do not rely completely on the Smart City Brake Support (SCBS) system:  
 The Smart City Brake Support (SCBS) 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 (SCBS) is a system which operates in response to a
vehicle ahead. The system may not be able to detect or react to two-wheeled vehicles
or pedestrians.
  The laser sensor for the Smart City Brake Support (SCBS) system is installed near
the rearview mirror. To assure the correct operation of the Smart City Brake Support
(SCBS), heed the following cautions.
 

 
 Do not apply stickers to the surface of the windscreen near the laser sensor
(including transparent stickers). Otherwise, the laser sensor may not be able to
detect vehicles ahead which could result in an accident.
 

 
 Do not apply coating agent to the windscreen. Otherwise, the laser sensor may
not be able to detect vehicles or obstructions in front which could result in an
accident.
 

 
 Do not disassemble the laser sensor.


 
 If cracks or damage caused by À ying gravel or debris is visible near the laser
sensor, stop using the Smart City Brake Support (SCBS) 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 on the windscreen near the laser sensor, the system may operate unnecessarily
and cause an unexpected accident.
  Refer to Stopping The Smart City Brake Support (SCBS) System Operation on
page 4-160 .
 

 
 When replacing the windscreen wipers or windscreen, consult an expert repairer,
we recommend an Authorised Mazda Repairer.

Do not modify the suspension:
If the vehicle height or inclination is changed, the system will not be able to correctly
detect vehicles ahead. This will result in the Smart City Brake Support (SCBS) system
not operating normally or mistakenly operating, which could cause a serious accident.

When Driving
i-ACTIVSENSE
WARNING
Turn off the Smart City Brake Support (SCBS) when the vehicle is running on a chassis
roller or being towed:
Turn off the Smart City Brake Support (SCBS) system to prevent mistaken operation
when the vehicle is running on a chassis roller or being towed.
Refer to the Stopping the Smart City Brake Support (SCBS) System Operation on page
4-160 on how to turn off the Smart City Brake Support (SCBS) system.
CAUTION
  When driving off-road in areas where there is grass or forage, it is recommended that
the Smart City Brake Support (SCBS) system be turned off.
  Always use tyres for all wheels that are of the speci¿ ed size, and the same
manufacturer, brand, and tread pattern. In addition, do not use tyres with signi¿ cantly
different wear patterns on the same vehicle as the Smart City Brake Support (SCBS)
system may not operate normally.
  The laser sensor includes a function for detecting a soiled windscreen and informing
the driver, however, depending on the conditions, it may not detect plastic shopping
bags, ice or snow on the windscreen. In such cases, the system cannot accurately
determine a vehicle ahead and may not be able to operate normally. Always drive
carefully and pay attention to the road ahead.

4–158
When Driving
i-ACTIVSENSE
NOTE
  The Smart City Brake Support (SCBS) system will not operate if the driver is
deliberately performing driving operations (accelerator pedal and steering wheel).
  The Smart City Brake Support (SCBS) system will operate under the following
conditions.
 


 The engine is running.



 The Smart City Brake Support (SCBS) warning light (amber) does not illuminate.



 The vehicle speed is between about 4 to 30 km/h (2 to 18 mph).



 The Smart City Brake Support (SCBS) system is not turned off.



 The DSC is not malfunctioning. 

 The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a near-
infrared laser beam and receiving the beam reÀ ected off the reÀ ector of the vehicle
ahead, and then using it for the measurement. Consequently, the Smart City Brake
Support (SCBS) may not operate under the following conditions:
 


 ReÀ ection of the laser is poor due to the shape of the vehicle ahead.



 The vehicle ahead is signi¿ cantly dirty.



 Under bad weather condition, such as rain, fog and snow.



 The window washer is being used or the windscreen wipers are not used when it's
raining.
 


 The windscreen is dirty.



 The steering wheel is turned completely left or right, or the vehicle is accelerated
rapidly and comes close to the vehicle ahead.
 


 Trucks with low loading platforms and vehicles with an extremely low or high
pro¿ le.




 Vehicles with certain shapes such as a vehicle carrier. 

 Under the following conditions, the Smart City Brake Support (SCBS) system may not
operate normally.
 


 Heavy luggage is loaded in the luggage compartment or on the rear seat.



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



 When driving on continuously curving roads, and entering and exiting exits.



 Elongated luggage or cargo is loaded onto installed roof rails and covers the laser
sensor.
 


 Exhaust gas from the vehicle in front, sand, snow, and water vapour rising from
manholes and grating, and water splashed into the air.
 


 When towing a malfunctioning vehicle.



 When driving with tyres having signi¿ cantly different wear.
