 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))

 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.

 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.

display and warning sound if the radar sensor (front) and the Forward Sensing 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 sensor (front) and the Forward Sensing Camera (FSC) determines that a collision is 
unavoidable, the automatic brake control is performed to reduce damage in the event of a 
collision.
  In addition, when the driver depresses the brake pedal, the brakes are applied 

¿ rmly and 

quickly to assist. (Brake Assist (SBS brake assist))

 WARNING

 Do not rely completely on the Smart Brake Support (SBS) system and always drive 
carefully: 
 The Smart Brake Support (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 traf

¿ c 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.  

 CAUTION
