Function sequence

1 Function prerequisites

Key in ignition lock in position 2 (C. 15)

Dome light switched off

Reverse gear not engaged

2 The ambient brightness is measured by a sensor (2) in the inside rearview mirror housing.
Simultaneously a second sensor (3) on the surface of the inside rearview mirror measures the intensity of the light hitting the inside rearview mirror.

-----------------------------------------------------------------------------------------

3 A control module integrated into the inside rearview mirror compares the signals from the two sensors (2 and 3).

4 If the intensity of the light reaching the surface of the inside rearview mirror is greater than the ambient brightness, the outside rearview mirror is dimmed by the control module in the inside rearview mirror.
