- Fig. 1 Turn signal and main beam lever: Switching adaptive headlight range control on/off
Applies to vehicles: with adaptive headlight range control
The adaptive headlight range control automatically regulates the
cone of light emitted by the main beam headlights depending on the
ambient surroundings.
A camera (located in the mounting for the interior mirror) detects
light sources from other road users. The vertical and horizontal
range of the headlights is varied smoothly and steplessly between
dipped and main beams. The system controls the activation/deactivation
of the main beams depending on how far away the traffic is on either
side of the road.
Controls
Important: The dipped beam headlights must be on, the light
switch must be set to AUTO and the automatic dip function must
be activated on the MMI
Link.
Push the lever to position -1- to activate the adaptive headlight
range control. The indicator lamp 
will light up in the instrument cluster display and the main
beams will be activated/deactivated automatically. If the indicator
lamp
lights
up, the main beams are partially or fully on.

Driver message in the instrument cluster display
main beam assist: system fault
Drive to a qualified workshop soon and have the fault rectified.
You can still switch the main beam headlights on and off manually.
WARNING!
The adaptive headlight range control is only intended to assist
the driver. The driver must always ensure that the headlights are
used when required, and may have to switch them on or off manually,
e.g. when the light conditions or visibility are poor. In the following
situations manual intervention may be necessary:
- Hazardous weather conditions such as fog, heavy rain and snow or water splashes.
- Roads on which oncoming traffic is partially concealed (e.g. on motorways).
- Indiscernible road users (e.g. cyclists with poor lighting)
- Tight corners, steep hill crests or valleys
- Poorly lit towns
- Highly reflective objects, such as road signs
- Windscreen misted up, dirty, frosted or covered by stickers in front of the sensor
Note
The range of the headlight beams will be adjusted automatically
when traffic in front is detected on either side of the road. This
prevents you from dazzling other road users.
