Deactivation of adaptive headlight movements in response to system faults
WARNING: This page does not describe the selected car, but rather 37 other vehicles, including the 2006 BMW 330Ci, 2006 BMW 325Ci, 2005 BMW M3, 2005 BMW 330xi, and 2005 BMW 330i. However, it is still accessible from the selected car via links, so may be relevant.
The green indicator light on the light switch cluster flashes if a system fault is present.
Dazzling of oncoming traffic must be prevented in the event of a system fault.
To this end, the swivelling movement of the adaptive headlights is deactivated as follows:
- If the stepper motors are still functional, the headlights are returned to the straight-ahead position. The headlights are no longer swivelled towards bends in the road.
- If it is no longer possible for a headlight to be moved back to the straight-ahead position, the headlight is tilted downwards (by the stepped motors for automatic headlight-range adjustment). This prevents dazzling of oncoming traffic.
- If the headlight cannot be tilted downwards, the bi-xenon bulb in this headlight is disabled as follows:
When the vehicle is parked, idle status (sleep mode) is detected by the AHL control unit (vehicle stationary and terminal R OFF for several minutes).
The bi-xenon bulb in the defective headlight is not switched on when the engine is restarted.
The front fog lights are switched on in order to ensure a minimum level of illumination.
The dipped beam headlights are not switched off while the vehicle is in motion.
