Hyundai Venue: Electro Chromic Inside Rear View Mirror / Description and operation
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.
