If the vehicle has this mirror, while sitting in a comfortable driving position, adjust the mirror so you can see clearly behind the vehicle. Grip the mirror in the center and move it up and down or side to side. The day/night control, located at the bottom of the mirror, allows adjustment to lessen glare from the lamps behind you. Move the lever right for nighttime use; move the lever left for daytime use.

There are three OnStar® buttons located at the bottom of the mirror face. For more information about OnStar® and the services it provides, see OnStar® System .
