Active main beam

The function can start while driving in the dark when the car's speed is approx. 20 km/h (approx. 12 mph) or higher. The function can also take streetlights into account. When the camera sensor no longer detects any oncoming car or car in front, main beam is switched on again after about a second.

Activate active main beam

Active main beam is activated and deactivated by turning the rotating ring on the right-hand stalk switch to position . The rotating ring then returns to position . When active main beam is activated, the symbol illuminates with a white glow in the driver display. When main beam is activated, the symbol shines blue.

If active main beam is deactivated while main beam is on, the lighting is immediately reset to dipped beam.

Limitations for active main beam

The camera sensor on which the function is based has limitations.

If this symbol is shown in the driver display, together with the message Active High Beam Temporarily unavailable, then switching between main and dipped beam must be performed manually. The symbol extinguishes when these message are shown.

The same applies if this symbol is shown together with the message Windscreen sensor Sensor blocked, see Owner's manual.

Active main beam may be temporarily unavailable e.g. in situations with dense fog or heavy rain. When active main beam becomes available again, or the windscreen sensors are no longer blocked, the message goes out and the symbol illuminates.
