The ECM (Electro Chromatic inside rear view Mirror) is for
dimming the reflecting light from a vehicle behind at night, in order
the user not to be dazzled by the light. The forward facing sensor
detects brightness of the surroundings, while the rearward looking
sensor the strength of the reflecting light so that adjusts the
reflexibility of the mirror in the range of 7~85%. But, when the reverse
gear is engaged, it stops functioning.

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