The optional Driving Assist function combines the camera-based systems Lane Departure Warning and Approach and Pedestrian Warning with the City Brake Activation.
The Lane Departure Warning detects lane markings and alerts the driver of an unintentional lane change at speeds above approx. 70 km/h by means of vibrations in the steering wheel and a visual warning in the instrument cluster. The warning is not activated when the lane change is deliberate, i.e. when the indicator is turned on.
While the Approach Warning with City Brake Activation detects vehicles, the Pedestrian Warning with City Brake Activation reacts to pedestrians. When there is a risk of collision, the Approach Warning triggers a two-stage warning. First, a symbol in the instrument cluster lights up, followed by an acoustic alarm. The Pedestrian Warning triggers a single-stage warning in the event of an acute risk of collision. If the system warns of a potential collision, the brakes are simultaneously preconditioned for a faster response. In the event of an emergency, the system applies the brakes.
