For 1990-2009 cars

Adjust the inside rearview mirror to see clearly behind your vehicle. Hold the mirror in the center to move it up or down and side to side. Use the day/night adjustment to help prevent glare from the headlamps behind you. Move the lever to the right for nighttime use and to the left for daytime use.

Vehicles with OnStar® have three additional control buttons located at the bottom of the mirror. See your dealer/retailer for more information about OnStar and how to subscribe to it. See OnStar® Systemfor more information on the services OnStar provides.
