and Operation
Description
The ECM (Electro Chromatic inside rear view Mirror) is intended
dim the reflecting light in the rear view mirror. The forward facing sensor
detects brightness of the surroundings, while the rearward looking sensor is
for the light from the rear. The strength of the light in the rear sensor is
used by the mirror to adjust the shading. It ranges from 7 to 85%. When the
reverse gear is engaged, it stops functioning.

The forward facing sensor sees if the brightness
of the surroundings is low enough for the mirror to operate its function.

| 2. |
The rearward looking sensor detects glaring of the
reflecting light from a vehicle behind.
|

The ECM is darkened to the level as determined by
the rearward looking sensor. When the glaring is no longer detected,
the mirror stops functioning.
