Inside rearview mirror with
automatic dimming feature
This mirror automatically responds to
light (ambient light and headlamp glare)
by dimming through an infinitely vari-
able range.
The mirror automatically reverts to its
clear, undimmed setting whenever you
move the selector lever to Reverse.
To ensure that the mirror continues to
operate properly, keep the two photo-
cells clean and unobstructed. One pho-
tocell is integrated in the mirror glass,
the other somewhat offset on the back
of the mirror.

mic technology used in this mirror, refer
