The SCBS F 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 (Smart City Brake Support (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.

Do not rely completely on the SCBS F system:
The SCBS F 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 SCBS F 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.
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 Smart City Brake Support [Forward] (SCBS F) system Operation (Search) on how to turn off the SCBS F system.
The SCBS F system will operate under the following conditions.
The engine is running.
The Smart Brake Support/Smart City Brake Support (SBS/SCBS) system warning indication/warning light (amber) does not illuminate.
(Rear-end collision warning)
The vehicle speed is about 4 to 80 km/h (2 to 50 mph).
(Brake control (Smart City Brake Support (SCBS) brake))
The vehicle speed is about 4 to 30 km/h (2 to 18 mph).
The SCBS F system is not turned off.
Under the following conditions, the SCBS F system may not operate normally:
The SCBS F system will not operate if the driver is deliberately performing driving operations (accelerator pedal and steering wheel).
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.
The brake pedal is depressed.
The steering wheel is being operated.
The selector lever is being operated.
In the following cases, the Forward Sensing Camera (FSC) determines that there is a vehicle ahead and the SCBS F may operate.
Objects on the road at the entrance to a curve.
Vehicles passing in the opposite lane while making a curve.
Metal objects, bumps, or protruding objects on the road.
When passing through a toll gate.
When passing through low gates, narrow gates, car washing machines, or tunnels.
If you suddenly come close to a vehicle ahead.
2-wheeled vehicles, pedestrians, animals or standing trees.
Vehicle is driven with some of the tires having significant wear.
