MIRRORS
Inside Day/Night Mirror
A two-point pivot system allows for horizontal and
vertical adjustment of the mirror. The mirror should be
adjusted to center on the view through the rear window.
Headlight glare from vehicles behind you can be reduced
by moving the small control under the mirror to the night
position (toward the rear of the vehicle). The mirror
should be adjusted while set in the day position (toward
the windshield).
