Smart City Brake Support (SCBS) (Some Models)
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 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 firmly and quickly to assist. (Brake Assist (SCBS brake assist))
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.
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 (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.
-
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.
-
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.
-
Do not disassemble the laser sensor (front).
-
If cracks or damage caused by flying 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 (Search).
-
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.
