The Driving Assistant feature combines the camera-based systems Lane Departure Warning and Approach and Pedestrian Warning with City Brake Activation.
The Attentiveness Assistant monitors driving behaviour for signs of tiredness in order to avoid dangerous situations. The system analyses the driver's steering behaviour. When it detects any abnormalities, a suggestion to take a break is shown in the Control Display.
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 and a visual warning in the instrument cluster. The warning is not activated if 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 – 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.
