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 con guration, 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 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. Refer toSymbols on page 275.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, seeIf the System Needs Service
on page 283andProblems with Route Guidance
