When you are 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 day/night adjustment allows you to adjust the mirror to avoid glare from the lamps behind you. Push the tab forward for daytime use and pull it for nighttime use.

If your vehicle has OnStar®, the buttons are located at the bottom of the mirror face. 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.

Cleaning the Mirror

When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror housing.
