each time the vehicle is started.
Vehicles with OnStar have three additional 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 the OnStar

(On/Off): Press to turn the dimming feature and/or
compass display on or off.
