Mirrors Automatic Dimming Rearview Mirror with OnStar® and Compass Your vehicle may have an automatic-dimming rearview mirror with a compass. There may be three additional buttons for the OnStar® system. See your dealer/retailer for more information on the system and how to subscribe to OnStar®. See OnStar® System on page 2-36 for more information about the services OnStar® provides. Compass Operation Press the on/off button once to turn the compass on or off. There is a compass display in the window in the upper right corner of the mirror face. Compass Calibration Press and hold the on/off button to activate the compass calibration mode. CAL will be displayed in the compass window on the mirror. The compass can be calibrated by driving the vehicle in circles at 5 mph (8 km/h) or less until the display reads a direction. If after a few seconds the display does not show a compass direction, (N for North for example), there may be a strong magnetic field interfering with the compass. Such interference may be caused by a magnetic antenna mount, note pad holder, or similar object. If the letter C or CAL appears in the compass window, the compass may need to be reset or calibrated. O (On/Off): This is the on/off button. Automatic Dimming Mirror Operation The automatic dimming mirror comes on each time the ignition is turned to start. To turn the automatic dimming feature off or back on, press the on/off button. The indicator light on the mirror is lit when the automatic dimming feature is on. 2-33
