The Driving Assistant feature combines the camera-based Lane Departure Warning and Approach and Pedestrian Warning systems with City Brake Activation.
The Lane Departure Warning detects lane markings and alerts the driver to an unintentional lane change at speeds above approx. 70 km/h by means of vibrations in the steering wheel. The warning is not activated if the lane change is deliberate, that is, when the turn indicator has been activated. Whereas 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 – a symbol in the instrument cluster lights up, followed by an acoustic alarm. The Pedestrian Warning operates at speeds between 10 and 60 km/h and emits a single-level warning in the event of acute danger. 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. This function can be limited by darkness and fog.
