Compass Variance (Zone)
Procedure

when the vehicle is moving. On
an automatic transmission

vehicle is in P (Park). On a
manual transmission vehicle,
only set it when the vehicle is
stopped.

displays.
2. Find the vehicle's current
location and variance zone
number on the map.
Zones 1 through 15 are
available.
3. Press
V to scroll through and
select the appropriate
variance zone.
4. Press
3 until the vehicle
heading, for example, N for
North, is displayed in the DIC.
5. Calibrate the compass. See
“Compass Calibration
Procedure” following.
Compass Calibration
The compass can be manually
calibrated. Only calibrate the
compass in a magnetically clean
and safe location, such as an open
parking lot, where driving the
vehicle in circles is not a danger.
Also calibrate the compass, away
from tall buildings, utility wires,
manhole covers, or other industrial
structures, if possible.
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. Interference may be
caused by a magnetic antenna
mount, 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.
