Smart City Brake Support (SCBS)
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
(front) 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 15 km/h (9.3 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))


Laser sensor

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 tire friction and road contact
because of water on the road surface). You can still have an accident.

When Driving

Do not rely completely on the Smart City Brake Support (SCBS) system:  


¾ 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.
 


¾ 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 2-wheeled vehicles or
pedestrians.
 


¾ The laser sensor (front) 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.
 

¾
 Do not apply stickers to the surface of the windshield near the laser sensor (front)
(including transparent stickers). Otherwise, the laser sensor (front) may not be able
to detect vehicles ahead which could result in an accident.
 

¾
 Do not apply coating agent to the windshield. Otherwise, the laser sensor (front)
may not be able to detect vehicles or obstructions in front which could result in an
accident.
 

¾
 Do not disassemble the laser sensor (front).


¾
 If cracks or damage caused by fl ying gravel or debris is visible near the laser sensor
(front), stop using the Smart City Brake Support (SCBS) system immediately and
have your vehicle inspected by an Authorized Mazda Dealer. If the vehicle continues
to be driven with cracks or scratch marks left on the windshield near the laser sensor
(front), the system may operate unnecessarily and cause an unexpected accident.
  Refer to Stopping The Smart City Brake Support (SCBS) System Operation on page
4-110 .
 

¾
 When replacing the windshield wipers or windshield, consult an Authorized Mazda
Dealer.


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.

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. See the next page on how to turn
off the Smart City Brake Support (SCBS).
Refer to Stopping The Smart City Brake Support (SCBS) System Operation on page 4-110 .

When Driving
i-ACTIVSENSE
CAUTION
 


¾ 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 .




¾ Always use tires for all wheels that are of the specifi ed size, and the same manufacturer,
brand, and tread pattern. In addition, do not use tires with signifi cantly diff erent wear
patterns on the same vehicle as the Smart City Brake Support (SCBS) system may not
operate normally.
 


¾ The laser sensor (front) includes a function for detecting a soiled windshield and informing
the driver, however, depending on the conditions, it may not detect plastic shopping bags,
ice or snow on the windshield. 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.

N O T E
 


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


y The Smart City Brake Support (SCBS) system will operate under the following conditions. 



y The engine is running.



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



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



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



y The DSC operation is not turned off using the DSC OFF switch.



y The DSC is not malfunctioning. 



y 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:
 


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



y The vehicle ahead is signi¿ cantly dirty.



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



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


y The windshield is dirty.



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


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



y Vehicles with certain shapes such as a vehicle carrier.
