2-78 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.
Setting the Variance
Turn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press the RESET button for
approximately five seconds. The last entered variance zone
number will be displayed. Press the MODE button until
the proper variance number, as shown on the map, is
showing. Press the RESET button to set the new variance
zone and resume normal operation.
The display will show all the display segments for half a
second to acknowledge the change in 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 ªCALº will be displayed, and all segments
of the compass will be illuminated 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.

for at least 10 seconds until the calibration symbol
appears and all segments of the compass display are
illuminated. Release the button and complete three 360

turns in an area free from large metal objects. The
calibration symbol will turn off and the compass reading
will be displayed.

The fuel economy used to calculate range is based on
the last few hours of driving.

FUEL USED (Trip Fuel Used): This shows the
accumulated fuel used since the last reset.

AVG SPEED (Average Speed): This shows the
average speed since the last reset.
Resetting the Trip Computer
Press and hold the RESET button for at least two
seconds. The reset is acknowledged with the display
showing all segments on for a period of half a second.
