Manual Rearview Mirror

Hold the inside rearview mirror in the center and move it for a clearer view behind the vehicle. Adjust the mirror to avoid glare from the headlamps behind you. Push the tab forward for daytime use and pull it for nighttime use.

Vehicles with OnStar® have three control buttons located at the bottom of the mirror. See your dealer for more information on the system and how to subscribe to OnStar. See OnStar Overview on page 14‑1.
