Global Positioning

System (GPS)

The position of the vehicle is
determined by using satellite
signals, various vehicle signals, and
map data.
At times, other interference such
as the satellite condition, road
configuration, condition of the
vehicle, and/or other circumstances
can affect the navigation system's
ability to determine the accurate
position of the vehicle.
Infotainment System
The GPS shows the current position
of the vehicle using signals sent by
the GPS Satellites. When the
vehicle is not receiving signals from
the satellites, a symbol appears on
the map screen. See Navigation
Symbols on page 57.
This system might not be available
or interference can occur if any of
the following are true:
Signals are obstructed by tall
buildings, trees, large trucks,
or a tunnel.
Satellites are being repaired or
improved.
For more information if the GPS is
not functioning properly, see
Problems with Route Guidance on
page 80 and If the System Needs
Service on page 81.
