Letter "C"
shown on the display
If letter "C" is displayed the compass
shall be reset. Make the car turn by 360°
at a speed equal to or lower than 8
km/h, until the display (fig. 3) shows
car running direction (North, South, East,
West).
In the event of significant moving away
from common driving zones (see map
fig. 4), it could be required to reset the
compass to compensate terrestrial mag-
netic field variations.
