The ECM (Electro Chromatic inside rear view Mirror) is for dimming the
reflecting light from a vehicle behind at night, Preventing glare from the light.
The forward facing sensor detects brightness of the surroundings, while the
rearward looking sensor detects the strength of the reflecting light and adjusts
the reflexibility of the mirror in the range of 7~85%. But, when the reverse
gear is engaged, it stops functioning.
