Global Positioning System (GPS)
The navigation system determines the position of your
vehicle by using satellite signals, various vehicle signals,
and map data.
The Global Positioning System (GPS) locates the current
position of your vehicle using signals sent by the United
States Department of Defense GPS satellites. While your
vehicle is receiving signals from these satellites, the GPS
symbol will not appear on the map screen.
However, at times, other interferences such as the
satellite condition, road configuration, the condition of
the vehicle, and/or other circumstances can interfere
with the system’s ability to determine the accurate
position of the vehicle. This is when the GPS symbol
will appear on the map screen.
This system may not be available or interferences may
occur if any of the following are true:
•
Signals are obstructed by tall buildings, large
trucks, or a tunnel.
•
Objects are located on the rear shelf.
•
Satellites are being repaired or improved.
•
After-market glass tinting has been applied to the
vehicle’s rear windshield.
Notice: Aftermarket glass tinting with metallic
material will interfere with the system’s ability to
receive GPS signals and cause the system to
malfunction. You might have to replace the rear
window to correct the problem. The repairs would
not be covered by your warranty. Do not apply
aftermarket glass tinting with metallic material to
the rear window of your vehicle.
If you are experiencing a problem, see Vehicle
Positioning on page 2-36 or Problems with Route
Guidance on page 2-37 for more information.
