BASIC FUNCTIONS Map database information and updates After replacing the tire, implement the operation described in the "Current position calibration". (For details, see page 95.) This navigation system uses tire turning data and is designed to work with factory− specified tires for your Toyota. 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.
