Installing tires that are larger or smaller than the originally equipped diameter may cause inaccurate display of the vehicle's position. The tire pressure also affects the diameter of the tires so please make sure the tire pressure of all four tires is correct. INFORMATION If your vehicle cannot receive GPS signals, you can correct the current position manually. For the information on setting the current position calibration, see page 59. 37
