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 interfere with 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
the GPS Satellites. When the
vehicle is not receiving signals from
the satellites, a symbol appears on
the map screen. See Navigation
Symbols on page 60.
This system might not be available
or interference can occur if any of
the following is true:
Signals are obstructed by tall
buildings, trees, large trucks,
or a tunnel.
Infotainment System
Satellites are being repaired or
improved.
For more information if the GPS is
not functioning properly, see
Problems with Route Guidance on
page 76 and If the System Needs
Service on page 77.

Vehicle Positioning

At times, the position of the vehicle
on the map could be inaccurate due
to one or more of the following
reasons:
The road system has changed.
The vehicle is driving on slippery
road surfaces such as in sand,
gravel, and/or snow.
The vehicle is travelling on
winding roads or long straight
roads.
The vehicle is approaching a tall
building or a large vehicle.
The surface streets run parallel
to a freeway.
