Compass Variance Compass variance is the difference between magnetic north and geographic north. In some areas of the country, the difference is great enough to cause the compass to give false readings. If this occurs, the compass must be set. Automatic Compass Calibration The compass is self-calibrating, which eliminates the need to manually set the compass. When the vehicle is new, the calibration process may not be complete. In these cases,the calibration symbol "C" will be displayed where the compass reading is normally displayed. To calibrate the compass, in an area free from large metal objects, make three 360 degree turns. The calibration symbol will turn off and the compass reading will be displayed. Manual Compass Calibration If the compass appears erratic and the calibration symbol does not appear, you must manually put the compass into the calibration mode. To get into this mode, do the following: 1. Turn the ignition on and cycle the DIC to the compass/temperature mode. 2. Press and hold the SET button for longer then three seconds. 2-103
