LIMITATIONS OF THE NAVIGATION SYSTEMThe Global Positioning System (GPS) de-veloped and operated by the U.S. Depart-ment of Defense provides an accuratecurrent position, normally using 4 or moresatellites, and in some case 3 satellites. TheGPS system has a certain level of inaccura-cy. While the navigation system will com-pensate for this most of the time, occasionalpositioning errors of up to 300 ft. (100 m)can and should be expected. Generally, po-sition errors will be corrected within a fewseconds.When the vehicle is receiving signals fromsatellites, the "GPS" mark appears at thetop left of the screen.The GPS signal may be physically obstruct-ed, leading to inaccurate vehicle position onthe map screen. Tunnels, tall buildings,trucks, or even the placement of objects onthe instrument panel may obstruct the GPSsignals.The GPS satellites may not send signals dueto repairs or improvements being made tothem.Even when the navigation system is receiv-ing clear GPS signals, the vehicle positionmay not be shown accurately or inappropri-ate route guidance may occur in some cas-es.This navigation system calculates thecurrent position using satellite signals,various vehicle signals, map data, etc.However, an accurate position may notbe shown depending on satellite condi-tions, road configuration, vehicle condi-tion or other circumstances.NOTICE●The installation of window tinting mayobstruct the GPS signals. Most windowtinting contains some metallic contentthat will interfere with GPS signal recep-tion of the antenna in the instrumentpanel. We advise against the use of win-dow tinting on vehicles equipped withnavigation systems.
