DIC Compass (Uplevel Only)

Your vehicle may have a compass in the Driver
Information Center (DIC).
Compass Zone
Press the menu button until COMPASS ZONE
displays. Press the set/reset button to change the
compass zone. Zones 1 through 15 are available.
The direction the vehicle is moving will be
displayed in the top right corner of the DIC display.
Compass Calibration
Under certain circumstances, such as during a long
distance cross-country trip, it will be necessary to
compensate for compass variance and reset the
zone through the DIC.
Compass variance is the difference between
the earth's magnetic north and true geographic
north. If not adjusted to account for compass
variance, the compass in the vehicle could give
false readings.
In order to do this, the compass must be set or
calibrated to the variance zone in which the vehicle
is traveling.
