Manual Rearview Mirror

When you are sitting in a comfortable driving position,
adjust the mirror so you can see clearly behind your
vehicle. Grip the mirror in the center to move it up
or down and side to side. The day/night adjustment
allows you to adjust the mirror to avoid glare from the
lamps behind you. Pull the tab forward for daytime use;
push it back for night use.

Automatic Dimming Rearview Mirror

Your vehicle may have an automatic dimming rearview
mirror. Your vehicle's mirror may also contain OnStar

controls. See OnStar System on page 2-41 for

At night, when the glare is too high, the mirror will
gradually darken to reduce glare. This change may take
a few seconds. The mirror will return to its clear daytime
state when the glare is reduced.
