Navigation

Global Positioning

System (GPS)
The position of the vehicle is
determined by using satellite
signals, various vehicle signals, and
map data.
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.
The GPS shows the current position
of the vehicle using signals sent by
GPS satellites. When the vehicle is
not receiving signals from the
satellites, a symbol appears in the
status bar.
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.
