Global Positioning System (GPS)

The Navigation System determines the position
of your vehicle 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's ability to determine
the accurate position of the vehicle.
The GPS shows the accurate current position of
your vehicle using signals sent by the GPS
Satellites of the United States Department of
Defense. When your vehicle is not receiving
signals from the satellites, a symbol will appear
on the map screen.
This system may not be available/or interference
may occur if the following happens:
Signal obstructions caused by tall buildings,
large trucks, tunnels,
objects located on top of the instrument panel,
satellites will not send signals if they are
being repaired or improved,
after-market glass tinting has been applied to
the vehicle's windows.
Notice: Do not apply after-market glass tinting
to the vehicle's windows. Glass tinting will
interfere with the system's ability to receive
GPS signals and cause the system to
malfunction. You might have to replace the
window to correct the problem. This would
not be covered by your warranty.
For more information if you are experiencing a
problem, see If the System Needs Service
on page 55 and Problems with Route Guidance
on page 55.
