Compass Calibration
WARNING: This page is about a different car, the 2002 Pontiac Montana, 2002 Oldsmobile Silhouette, and 2002 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.
Depress and hold down both the MODE and E/M buttons while the DIC is in the Compass/Temperature mode. Ignore the variation zone which shows up after 5 seconds and continue holding the buttons. After ten seconds the DIC will acknowledge that calibration is requested by illuminating the C indicator on the compass display if it's not already lit. To calibrate the compass, drive the vehicle through two circles less than 5 mph in a magnetically clean area. The C indicator will disappear and the DIC will display the proper vehicle display.
