The system can warn you when a risk of an accident is detected, support you when performing emergency braking and, in case of an emergency, brake automatically. It uses radar sensors and a stereo camera to detect stationary vehicles or vehicles that are stopping or driving more slowly. It can also detect crossing traffic at junctions, vehicles at the end of a traffic jam and pedestrians in the danger zone. When a hazard is detected, the system warns the driver visually and audibly. If the driver reacts and brakes, the system increases the braking effect (if necessary, up to full braking application). If the driver does not react, Active Brake Assist brakes the vehicle autonomously.
