5-6 Instruments and Controls
If the DIC display does not show a
heading, for example, N for North,
or the heading does not change
after making turns, there may be a
strong magnetic field interfering with
the compass. Such interference
may be caused by a magnetic CB or
cell phone antenna mount, a
magnetic emergency light, magnetic
note pad holder, or any other
magnetic item. Turn off the vehicle,
move the magnetic item, then turn
on the vehicle and calibrate the
compass.
To calibrate the compass, use the
following procedure:
Compass Calibration Procedure
1. Before calibrating the compass,
make sure the compass zone is
set to the variance zone in which
the vehicle is located. See
Compass Variance (Zone)
Procedure earlier in this
section.
Do not operate any switches
such as window, sunroof,
climate controls, seats, etc.
during the calibration procedure.
2. Press the vehicle information
button until PRESS
CALIBRATE COMPASS
displays.
3. Press the set/reset button to
start the compass calibration.
4. The DIC will display
CALIBRATING: DRIVE IN
CIRCLES. Drive the vehicle in
tight circles at less than 8 km/h
(5 mph) to complete the
calibration. The DIC will display
CALIBRATION COMPLETE for a
few seconds when the
calibration is complete. The DIC
display will then return to the
previous menu.
