For details, refer to Section 4, “Smart City Brake Support [Forward] (SCBS
F)”, “Smart City Brake Support [Reverse] (SCBS R)”.
Smart City Brake Support [Forward] (SCBS F)/Smart City Brake Support [Reverse] (SCBS R)
The Smart City Brake Support [Forward] (SCBS F) is a system designed to reduce
damage in the event of a collision by operating the brake control when the system’s
laser sensor (front) detects a vehicle ahead and the system determines that a
collision is unavoidable. The system operates while the vehicle is moving in the
forward direction in the speed range of 4 to 30 km/h (3 to 18 mph), reducing
damage in the event of a collision.
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).
Smart City Brake Support [Forward] (SCBS F)
The Smart City Brake Support [Reverse] (SCBS R) is a system designed to reduce
damage in the event of a collision by operating the brake control when the system’s
ultrasonic sensors detect a vehicle or a wall at the rear of the vehicle and the system
determines that a collision is unavoidable.
The system operates while the vehicle is reversing in the speed range of 2 to 8 km/h
(2 to 4 mph), reducing damage in the event of a collision.
Smart City Brake Support [Reverse] (SCBS R)
Do not rely completely on the system:
• (Smart City Brake Support [Forward] (SCBS F))
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
Do not modify the suspension: • (Smart City Brake Support [Reverse] (SCBS R))The Smart City Brake Support [Forward] (SCBS F) operates in response to
a vehicle (4-wheeled vehicle) in front of your vehicle. Operation in
response to 2-wheeled vehicles or pedestrians is not guaranteed.
The Smart City Brake Support [Reverse] (SCBS R) operates in response to
a vehicle (4-wheeled vehicle) behind of your vehicle or a wall. Operation in
response to 2-wheeled vehicles or pedestrians is not guaranteed.
