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. It is suggested to calibrate
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 eld
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 adjust for compass variance and to calibrate the
compass, use the following procedure:
Compass Variance (Zone) and Calibration
Procedure
1. Do not set the compass zone when the vehicle is
moving. Only set it when the vehicle is in PARK (P).
Press the options button until COMPASS
CALIBRATION MODE displays.2. Find the vehicle’s current location and variance
zone number on the map.
Zones 1 through 15 are available.
3. Press the set/reset button to scroll through and
select the appropriate variance zone.
4. Press the options button to advance to the
calibration screen.
Do not operate any switches such as window,
sunroof, climate controls, seats, etc. during
the calibration procedure.
