Model All (CAR)
with code 249 (Automatic dimming inside rearview mirror and outside mirrors)
Overview
This document contains the following information:
- General
- Function requirement
- Function
General
The mirror glass of the outside mirror of the driver's side can be continuously variably dimmed by means of an electrolyte gel. As a result, a dazzling due to light sources in the field of vision of the outside mirror can be prevented.
Function requirement
- Circuit 15R ON
- Interior lighting switched off
- Reverse gear not engaged
Function
The electrolyte gel of the mirror glass is actuated by the driver's door control unit depending on the inside rearview mirror request. The crystals of the electrolyte gel react to the control voltage, align themselves in a specific angle and thus darken the mirror glass. Dimming is canceled if the interior lighting is switched on or reverse gear is engaged.
