- Adjustment of headlight horizontal aim
- Deactivation of adaptive headlights function under extreme handling conditions
- Deactivation of adaptive headlights function in response to system faults
- Setting headlights to parked position
- Automatic headlight-range adjustment
- Adaptive headlights for automatic driving lights control
- Turning light
NOTE:
Different control units for adaptive headlights.
- E60, E61, E63, E64, E65, E66 up to 03/2005: The adaptive headlights are actuated by the AHL control unit.
- E60, E61, E63, E64, E65, E66 from 03/2005: The adaptive headlights are actuated by the light module (LM).
- E70, E81, E87, E90, E91, E92, E93: The adaptive headlights are actuated by the footwell module (FRM).
The footwell module has its own system description.
