The "DISP2" allows you to select a Display or Non-display mode of the compass. Usually the "DISP2" is used to select of the steering pad switch.

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 LEXUS hand-held tester.

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.

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 using a demagnetizer and perform calibration again.

1. Turn the ignition switch ON.
2. Check that the compass display indicates an azimuthal direction (N, NE, E, SE, S, SW, W, or NW).

Using the LEXUS hand-held tester, select the customize menu.

1. Keep pressing the "DISP2" for 6 sec. after selection of the compass display mode will activate the calibration setting mode.
2. Drive the vehicle at a slow speed of 8 km/h (5 MPH) or less in the circular direction.
3. Driving round the circle 1 to 3 times will display the azimuthal direction on the display, completing the calibration.
4. 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.
