Setting headlights to parked position
WARNING: This page is about a different car, the 2008 BMW 760Li, 2007 BMW 760Li, 2006 BMW 760i, 2006 BMW 760Li, and 2005 BMW 760i. However, it is still accessible from the selected car via links, so may be relevant.
When terminal R is switched off, the headlights move to the parked position. The parked position is important for the headlights' next calibration sequence: From the parked position, the headlights are run through a calibration sequence in the pre-drive-check. During each calibration sequence, the control unit for adaptive headlights relearns the straight-ahead position for the headlights.
When the headlights have reached the parked position, the stepper motor controllers SMCs inform the control unit for adaptive headlights ("verification").
The control unit for adaptive headlights deactivates the stepper motor controllers.
The run-down period lasts approx. 10 seconds.
