Global Positioning
System (GPS)
The navigation system determines
the position of the vehicle by using
satellite signals, various vehicle
signals, and map data.
At times, other interferences such
as the satellite condition, road
configuration, the 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 of the United
States Department of Defense.
When the vehicle is not receiving
signals from the satellites, a symbol
appears on the map screen. Refer
to
Navigation Symbols on page 46 .
This system may not be available or
interferences may occur if:
. Signals are obstructed by tall
buildings, trees, large trucks,
or a tunnel.
. Objects that are placed on top of
or near the instrument panel.
. Satellites are being repaired or
improved.
. After-market glass tinting has
been applied to the vehicle's
windshield.
Notice: Do not apply after-market
glass tinting to the vehicle's
windows. Glass tinting interferes
with the system's ability to
receive GPS signals and causes
the system to malfunction.
The window might have to be
replaced to correct the problem.
This would not be covered by the
warranty.
