Kia Optima: DescriptionThe 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.
