Global Positioning System (GPS)
Th
e current position of the vehicle is
determined by using satellite signals and
various vehicle signals.
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.
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
