Your vehicle may have a rearview mirror with the OnStar® system.
Control buttons for the OnStar® system are at the bottom of the mirror. See your dealer for more information on the OnStar® system and how to subscribe to OnStar®. Also, see OnStar® System for more information about the services OnStar® provides.
While sitting in a comfortable driving position, adjust the rearview mirror so you can see clearly behind your vehicle. Grip it in the center to move it up or down and side to side. The day/night control, located at the bottom of the mirror, adjusts the mirror to reduce headlamp glare from behind during evening or dark conditions. Move the control to the right for night conditions. Return it to the center for daytime use.
