Hold the inside rearview mirror in the center to move it for a clearer view of behind your vehicle. Adjust the mirror to avoid glare from the headlamps behind you. Pull the lever, located at the bottom of the mirror for nighttime use. Return the lever to its original position for the day position.

Vehicles with OnStar® have three additional control 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 on the services OnStar® provides.
