GM Service Manual Online
For 1990-2009 cars only

The vehicle may have an inside rearview mirror with OnStar® . See your dealer for more information on the system and how to subscribe to OnStar®. See OnStar® System for information on the services OnStar® provides.

While sitting in a comfortable position, adjust the mirror so you can see clearly behind your vehicle. Move the mirror in the center to move it up or down and side to side. The control at the bottom of the mirror is the day/night feature that allows adjustment to the mirror so that the glare of headlamps from behind is reduced. Move the control from left to right for day or night conditions.
