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;
1. Stop the vehicle in a level place and
switch the display to the outside tem-
perature. (To switch to this mode, see
"—Outside temperature display" in this
Section.)
2. Push and hold both the "MODE" and
"E/M" buttons simultaneously for 5 sec-
onds until the "VAR" indication appears
on the compass display.
3. Push the "E/M" button several times
until the desired zone number appears
on the compass display.
If the button is not pushed for 10 sec-
onds, the display returns to the compass/
outside temperature mode and the number
that is last set is memorized.
To select the zone where the vehicle is
currently located, refer to the following
map.
