To adjust the angle of the mirror, move the mirror to a position that allows you to see out of the back window. To adjust the height of the mirror, adjust the arm that connects the mirror to the windshield.

To reduce glare from lights behind you, move the lever toward you to the night position.

There are also OnStar® buttons 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.
