Mirrors: Description and Operation

Automatic Dimming Interior Rearview Mirror

The automatically dimming interior rearview mirror dims progressively when the driver is blinded from the rear.

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

The electronic element registers light incidence from the front and rear through the photo sensors.

If the incident light from the rear is greater than that from the front, a current flows through the electronic element to a conductive coating.

The applied current will change the color of the electrolytes. The higher the voltage, the darker the electrolyte. The incident light will be reflected to a lesser degree.

The dimming function is deactivated when reverse gear is selected or mirror is deactivated manually via switch. The interior rearview mirror can be used, for example, to back out of a dark garage.

Function





1 Interior Rearview Mirror

• Checking function:

• Switch the ignition on.

• Cover the photo sensor -=> [ (Item 8) Photo sensor ] - and illuminate the photo sensor -=> [ (Item 2) Photo sensor ] - with a flashlight. The mirror surface must darken during this process. (Reverse gear must not be selected and dimming function must be activated).
