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.

Compass/Temperature mode. Press the RESET button
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.
Error Displays

An error of the vehicle's speed sensor or fuel sender
will cause ª
-E-º to be displayed.

In the absence of vehicle communications, a double
dash ª
--º is displayed.
If one of these error messages appear, see your dealer.

stepped through by pushing the MODE button.
The information will appear in the following order:

the average fuel economy since the last reset.

INST ECON (Instantaneous Fuel Economy):
This shows fuel economy for the most recent second
of driving.

RANGE (Trip Range): This shows the estimated
distance that can be traveled with the remaining fuel.
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.
A reset can only be done in AVG ECON, FUEL USED
