Forward drive detection
When you are driving forward, the following functions of the Smart Brake Support (SBS) operate.
-
Forward detection function
Do not rely completely on the SBS:
The SBS is only designed to reduce damage in the event of a collision.
The system may not operate normally depending on the target object, weather conditions, or traffic conditions. Over reliance on the system leading to the accelerator pedal or brake pedal being mistakenly operated could result in an accident.
In the following cases, turn the SBS off to prevent a mis-operation.
-
The vehicle is being towed or towing another vehicle.
-
The vehicle is driven on rough roads such as in areas where there is grass and foliage or off-road.
Refer to Stopping the Smart Brake Support (SBS) System Operation (Search).
Forward detection function
The forward detection function is designed to reduce damage in the event of a collision with target objects at the front.
The forward detection function detects target objects (vehicles ahead, pedestrians, and bicycles) using the front radar sensor and the Forward Sensing Camera (FSC). If there is a possibility of your vehicle colliding with a target object at the front, you are notified of possible danger by a warning sound and a warning indication on the display.
Furthermore, if the possibility of a collision increases, the brake control is performed to reduce damage in the event of a collision. In addition, when the driver depresses the brake pedal, the brakes are applied firmly and quickly to assist.
(Vehicles with Driver Monitoring (DM))
If the system determines that the driver is not paying attention to the road, it activates the collision warning earlier than normal.
