ADVANCED FUNCTIONS TIRE CHANGE CALIBRATION The tire change calibration function will be used when replacing the tires. This function will adjust the miscalculation caused by the circumference difference between the old and new tires. If this procedure is not performed when the tires are replaced, the current vehicle position mark may be incorrectly displayed. To perform a distance calibration procedure, touch "Tire Change" on the "Calibration" screen. The message appears and the quick distance calibration is automatically started. A few seconds later, a map screen will be displayed. 111
