Can provide relief when driving on the motorway or in stop-start traffic.

The Active Distance Assist DISTRONIC can keep the clearance to the vehicle in front set by the driver and can relieve them, for example, when driving on the motorway or in stop/start traffic. The system accelerates the vehicle by itself and brakes it with a maximum of half the vehicle's braking power in order to maintain a safe distance.

If the system recognises that stronger braking is necessary, the driver is visually and acoustically warned, so that they – if necessary – can slow down the vehicle. If there is a risk of a collision, Active Brake Assist additionally intervenes in order to avoid an accident where possible.
