The concept

When the low beams are switched on, this system automatically switches the high beams on and off. The procedure is controlled by a sensor on the front of the interior rearview mirror. The assistant ensures that the high beams are switched on whenever the traffic situation allows.

The driver can intervene at any time and switch the high beams on and off as usual.
