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.
