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 variance must be set.

Turn the ignition on and cycle the DIC to the compass/
temperature mode. Press both the
E/M
and MODE
buttons simultaneously for approximately five seconds.
The last entered variance zone number will be displayed.
Press the E/M button until the proper variance number,
as shown on the map, is showing. Press the MODE
button to set the new variance zone and resume normal
operation.
The display will show all the display segments briefly to
acknowledge the change
in
the zone number.
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"
turns. The calibration
symbol will turn
off and the compass reading will
be displayed.
