Deactivation Of Adaptive Headlights Function In Response To System Faults
WARNING: This page does not describe the selected car, but rather 46 other vehicles, including the 2008 BMW M5, 2008 BMW 650i, 2007 BMW Z4, 2007 BMW M6, and 2007 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.
In the event of a system error, the indicator light on the light switch will flash.
Dazzling of oncoming traffic must be prevented in the event of a system fault.
For this reason, the adaptive headlights function 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 moved 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 up, the control unit registers sleep mode for the adaptive headlights, as follows: Vehicle standstill and terminal R OFF for several minutes.
The next time the vehicle is restarted, the bi-xenon light of the defective headlight is not switched on.
The front foglights are switched on in order to ensure a minimum level of illumination.
The dipped headlights are not switched off while the vehicle is in motion.
