Mazda CX-9 Owners Manual: Advanced Smart City Brake Support (Advanced SCBS)

The Advanced SCBS alerts the driver of a possible collision using the display and a warning sound when the Forward Sensing Camera (FSC) detects a vehicle ahead or pedestrian and determines that a collision with the object is unavoidable while the vehicle is driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph) if the object is a vehicle ahead and about 10 to 80 km/h (6.2 to 50 mph) if the object is a pedestrian. In addition, the system reduces damage in the event of a collision by operating the brake control (Advanced SCBS brake) when the system determines that a collision is unavoidable. In addition, when the driver depresses the brake pedal, the brakes are applied firmly and quickly to assist. (Brake Assist (Advanced SCBS brake assist) )

WARNING

Do not rely completely on the Advanced SCBS system:

• The Advanced 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 Advanced SCBS system operates in response to a vehicle ahead or a pedestrian. The system does not operate in response to obstructions such as a wall, 2-wheeled vehicles, or animals.

CAUTION

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.

Refer to Stopping the Advanced Smart City Brake Support (Advanced SCBS) System Operation on how to turn off the Advanced SCBS system.

  • If there is the possibility of partial contact with a vehicle ahead.
  • The vehicle is driven on a slippery road surface such as wet roads or icy or snow-bound roads.
  • The braking performance is adversely affected due to cold temperatures or wet brakes.
  • The vehicle is driven at the same speed as the vehicle ahead.
  • The accelerator pedal is depressed.

Collision Warning

If there is the possibility of a collision with a vehicle ahead, the beep sounds continuously and a warning is indicated in the multi-information display or the active driving display.

NOTE The operation distance and volume of the collision warning can be changed.

Automatic Brake Operation Display

The automatic brake operation display is indicated on the multi-information display after the Advanced SCBS is operated.

NOTE

• The collision warning beep sounds intermittently while the Advanced SCBS brake or brake assist (Advanced SCBS brake assist) is operating.
• If the vehicle is stopped by the Advanced SCBS operation and the brake pedal is not depressed, the warning beep sounds 1 time after about 2 seconds and the Advanced SCBS brake is automatically released.
