Mazda 6 Owners Manual: Smart City Brake Support (SCBS)

The Smart City Brake Support (SCBS) 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 firmly and quickly to assist. (Brake Assist (SCBS brake assist))

WARNING

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 2-wheeled vehicles or pedestrians.

CAUTION

When driving off-road in areas where there is dense grass, it is recommended that the Smart City Brake Support (SCBS) system be turned off.

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.
