While sitting in a comfortable driving position, adjust the mirror so you can see clearly behind your vehicle. Hold the mirror in the center to move it up or down and side to side.

The vehicle may have an automatic dimming rearview mirror with the OnStar® System. The automatic dimming feature is turned on or off by pressing the left button, located on the lower part of the mirror, for up to three seconds. When turned on, this mirror functions like the automatic dimming rearview mirror described previously. See Automatic Dimming Rearview Mirror .

There are also three OnStar® buttons located at the bottom of the mirror. See your dealer/retailer for more information on the system and how to subscribe to OnStar®. See OnStar® System for more information about the services OnStar® provides.
