Mirrors Automatic Dimming Rearview Mirror with Intellibeam®, OnStar®, Compass, and Temperature Display Your vehicle may have an automatic dimming rearview mirror with Intellibeam®, OnStar®, compass and temperature display. For more information on OnStar®, see OnStar® System on page 2-50. For more information on Intellibeam®, see "Intellibeam® Intelligent High-Beam Headlamp Control System" under Exterior Lamps on page 3-16. The mirror includes an eight-point compass display in the upper right corner of the mirror face. When on, the compass automatically calibrates as the vehicle is driven. Outside temperature is also shown in the display. Compass Operation AUTO 3: Press and hold the "auto highbeam" button for about three seconds to turn the compass/temperature display on or off. When the ignition and the display features are on, the display will show two character boxes for about two seconds. After two seconds, the mirror will display the compass heading and temperature. Compass Calibration If after two seconds the display does not show the correct 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, magnetic note pad holder, or a similar magnetic item. The compass can be placed in calibration mode manually by pressing and holding the "auto highbeam" button for about nine seconds until CAL is shown in the compass display. The mirror can then be calibrated by driving the vehicle in circles at 5 mph (8 km/h) or less until the display reads the correct direction. Automatic Dimming Your vehicle has an inside automatic dimming rearview mirror. The automatic dimming feature is activated whenever the vehicle is turned on and dims only during nighttime driving. 2-41
