5. GPS (GLOBAL POSITIONING SYSTEM) Inappropriate route guidance may occur in the following cases: • When turning at an intersection off the designated route guidance. • If you set more than one destination but skip any of them, auto reroute will display a route returning to the destination on the previous route. • When turning at an intersection for which there is no route guidance. • When passing through an intersection for which there is no route guidance. • During auto reroute, the route guidance may not be available for the next turn to the right or left. • During high speed driving, it may take a long time for auto reroute to operate. In auto reroute, a detour route may be shown. • After auto reroute, the route may not be changed. • If an unnecessary U-turn is shown or announced. • If a location has multiple names and the system announces one or more of them. • When a route cannot be searched. • If the route to your destination includes gravel, unpaved roads or alleys, the route guidance may not be shown. • Your destination point might be shown on the opposite side of the street. • When a portion of the route has regulations prohibiting the entry of the vehicle that vary by time or season or other reasons. • The road and map data stored in the navigation system may not be complete or may not be the latest version. After replacing a tire, implement the operation described in the "TIRE CHANGE CALIBRATION". (See page 105.) INFORMATION ● This navigation system uses tire turning data and is designed to work with factory-specified tires for the vehicle. Installing tires that are larger or smaller than the originally equipped diameter may cause inaccurate display of the current position. The tire pressure also affects the diameter of the tires, so make sure that the tire pressure of all 4 tires is correct. 112
