Vehicle Positioning

At times, the position of the vehicle on the map could be inaccurate due to one or more of the following reasons: • The road system has changed. • The vehicle is driving on slippery road surfaces such as sand, gravel, or snow. • The vehicle is traveling on winding roads or long straight roads. • The vehicle is approaching a tall building or a large vehicle. • The surface streets run parallel to a freeway. • The vehicle has been transferred by a vehicle carrier or a ferry. • The current position calibration is set incorrectly. • The vehicle is traveling at high speed. • The vehicle changes directions more than once, or the vehicle is turning on a turn table in a parking lot. • The vehicle is entering and/or exiting a parking lot, garage, or a lot with a roof. • The GPS signal is not received. • A roof carrier is installed on the vehicle. • Tire chains have been installed. • The tires are replaced or worn. • The tire pressure for the tires is incorrect. • This is the first navigation use after the map data is updated. • The 12-volt battery is disconnected for several days.

• The vehicle is driving in heavy traffic where driving is at low speeds, and the vehicle is stopped and started repeatedly.
