Your vehicle has an automatic dimming inside rearview mirror. The mirror also contains OnStar® controls. For more information about OnStar®, see OnStar® System .

The automatic dimming feature is active each time the vehicle is started.

To turn the automatic dimming feature on or off, press and release the on/off button. The indicator light will illuminate when this feature is active.

When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing.
