Automatically dimming outside mirror and inside rearview mirror, function sequence
The mirror glass of the inside rearview mirror (A67) and left electrically adjustable and heated outside mirror (M21/1) is electro-chromatically dimmable.

This is realized by a layer of electrolyte gel in the mirror which controls the light permeability in increments depending on the voltage applied.

The inside rearview mirror unit senses the ambient light via the mirror dimming sensor, forward (A67h1) and the light hitting the mirror glass via the mirror dimming sensor, rearward (A67h2).

The overhead control panel control unit evaluates these input factors and supplies dimming information as actuation voltage.

Dimming of the inside rearview mirror unit takes place by actuating the mirror dimming (A67h3). The left outside mirror is dimmed by actuating the mirror dimming (M21/1h1) by the left door control unit (N69/1).

If an interior lamp is switched on during mirror dimming or the reverse gear is engaged, the dimming is interrupted.
