Autobeam.
The Autobeam system switches main beam on and off automatically as required, relieving you of the need to keep adjusting the lights. Once activated, Autobeam monitors the traffic and outside light via an image sensor on the rear-view mirror and decides whether main beam should be switched on. If the system detects oncoming traffic or vehicles ahead of you or if light levels increase sufficiently, it then switches main beam off again.
