To return the mirror back to the day position, push the lever away from you. The mirror also has an eight-point compass and temperature display in the upper right corner on the mirror face and a three-button Onstar@system. When the automatic dimming feature is turned on, the mirror automatically changes to reduce glare from headlamps behind you. A photocell on the mirror senses when it is becoming dark outside.

This change may take a few seconds. The mirror will return to its clear, daytime state when the glare is reduced.
