This vehicle may have an automatic dimming inside rearview mirror with OnStar®. It may also have Intellibeam®. For more information on Intellibeam™, see "Intellibeam™ Intelligent High-Beam Headlamp Control System" under Exterior Lamps. For more information on OnStar®, see OnStar® System.

Automatic dimming reduces the glare of lights from behind the vehicle. The dimming feature comes on and the indicator light illuminates each time the vehicle is started.

Do not spray glass cleaner directly on the mirror. Use a soft towel dampened with water.
