CALIBRATING THE COMPASS (deviation
calibration)
The direction display on the compass
deviates from the true direction deter-
mined by the earth's magnetic field. The
angle of deviation varies according to the
geographic position of the vehicle.
To adjust for this deviation, stop the ve-
hicle and push the "MODE" button several
times until "ZONE XX" appears on the
calendar display. Then push the "RESET/
ADJ" button, referring to the following map
to select the number of the zone where
the vehicle is.
