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 than 

three seconds.
