Mirrors: Description and Operation

Automatic Dimming Interior Rearview Mirror

The automatic dimming interior rearview mirror darkens infinitely when the driver is "blinded" from behind.

It consists of a mirror element and an electric element with two photo sensors.

The electronic element recognizes the light incidence from front and back.

If the light incidence is greater from the rear than from the front the electronics apply voltage to the conductive coating.

The applied voltage changes the color of the electrolyte. The greater the voltage the darker the electrolyte. Therefore the light incidence is reflected to a lesser degree.

The automatic dimming function is deactivated when reverse gear is selected or mirror is deactivated manually via switch. One can use the mirror to back out of a dark garage.

- Switch on ignition.
- Cover photosensor and illuminate photosensor using a flashlight, mirror surface must darken when doing this. (Reverse gear must not be selected and dimming function must be activated).

2 - Photosensor
3 - Glass pane
4 - Electrolyte coating
5 - Silver reflective coating
6 - Conductive coating
7 - Switch
- For manual deactivation/activation of automatic dimming function
