The vehicle may have a mirror with Onstar®. While 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 and down and side to side.
The mirror has a day/night control located at the bottom. Turn the control to the right for the night position to reduce glare from other vehicles' headlamps. Turn the control to the front for the day position.
There are also three OnStar® 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 about the services OnStar® provides.
