Global Positioning

System (GPS)

The position of the vehicle is
determined by using satellite
signals, various vehicle signals,
and map data.
At times, other interferences such
as the satellite condition, road
configuration, the condition of the
vehicle and/or other circumstances
can interfere with the navigation
system's ability to determine the
accurate position of the vehicle.
The GPS shows the current position
of the vehicle using signals sent by
the GPS Satellites of the United
States Department of Defense.
When the vehicle is not receiving
signals from the satellites, a symbol
appears on the map screen. See
Infotainment System
This system might not be available
or interferences can occur if any of
the following is 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 If the
system needs service and Problems
with Route Guidance.
