1.SELECTING COMPASS DISPLAY MODE
The "DISP2" of the steering pad switch allows you to select a Display or Non-display mode of the
compass.
2.SETTING ZONE
Deviation between the magnetic north and "actual north" differs depending on the terrestrial location,
therefore, an adjustment in magnetism is required. Since the magnetic condition differs according to the
area where the vehicle will be used, it is necessary for each user to set the zone. (Refer to "Compass Zone
Map"). The zone setting can be changed using the hand-held tester.
3.PERFORMING CALIBRATION
Because each vehicle has its own magnetic field, calibration should be performed for each vehicle. This
compass function is used when storing the record of the vehicle's magnetic field.
4.WHEN COMPASS MAGNETIZED:
A compass could be magnetized during shipping by vessels or freight cars. Before delivery, therefore,
make sure to perform calibration and ensure that calibration can be done. If it cannot be done (cannot
complete in spite of driving round several times), it may be caused by magnetization. Demagnetize the
vehicle usin
g a demagnetizer and perform calibration again.

6.SELECTING DISPLAY MODE
a. Turn the ignition switch to the ON position.
b. Check that the compass display indicates an azimuthal direction (N, NE, E, SE, S, SW, W, or NW).
7.ZONE SETTING MODE
Usin
g the hand-held tester, select the customize menu.

8.CALIBRATION SETTING MODE
a. Keep pressing the "RESET" for 6 sec. after selection of the compass display mode will activate the
calibration setting mode.
b. Drive the vehicle at a slow speed of 8 km/h (5 MPH) or less in the circular direction.
c. Driving round the circle 1 to 3 times will display the azimuthal direction on the display, completing
the calibration.
d. To finish the calibration mode, press the DISP2 switch long when the calibration is finished or
during the calibration.
HINT:

Once calibration is completed, it is not necessary to perform the above procedures unless the magnetic
field strength is drastically changed.
HINT:
Inspect the related "Fuse" and "Relay" before confirming the suspected area as shown in the charts below.
