ADVANCED FUNCTIONS POSITION/DIRECTION CALIBRATION 1. Move the cursor mark to your desired point by operating the select and scroll lever of the navigation controller. Push the "ENTER" button on the navigation controller. TIRE CHANGE CALIBRATION The tire change calibration function should be used when the tires are replaced. This will adjust for any possible change in tire circumference from the old tires to the new ones. If this procedure is not performed when tires are replaced, the current vehicle position mark may become incorrect. To execute the fast distance tire calibration procedure, select the "Tire change" switch on the "Calibration" screen. The message appears and the fast distance calibration is automatically started. A few seconds later, the map screen will be displayed. 2. Operate the select and scroll lever of the navigation controller, so that the screen direction is facing to your desired direction. Push the "ENTER" button on the navigation controller, and then the map screen will be displayed. 96
