MIRRORS
Inside Day/Night Mirror
A single ball joint mirror is provided in the vehicle. It is
a twist on mirror that has a fixed position. The mirror
head can be adjusted up, down, left, and right for various
drivers. 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).
