VEHICLE MAGNETIC COMPENSATION

M1543009700158

Confirmation of magnetization and
demagnetization

The RV meter automatically conducts geomagnetization cali-
bration by sampling direction data while the vehicle is normally
driving. The calibration can be done manually at any time.

.

1. Press function switch 3 for three seconds or more during the

environment information screen to call up the screen as
shown in the illustration.

2. When function switch 3 (CAL.COMP) is pressed, a message

of urging geomagnetization calibration is displayed.
