ADVANCED FUNCTIONS
TIRE CHANGE CALIBRATION
The tire change calibration function will be
used when replacing the tires. This function
will adjust the mis-calculation caused by the
circumference difference between the old
and new tires. If this procedure is not per-
formed when tires are replaced, the current
vehicle position mark may be incorrectly dis-
played.
To perform a distance calibration proce-
dure, touch "Tire Change" on the "Cal-
ibration" screen.
The message appears and the quick distance
calibration is automatically started. A few
seconds later, a map screen will be displayed.
