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 39.
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.
For more information if the GPS is
not functioning properly, see
Problems with Route Guidance on
page 89 and If the System
Needs Service on page 90.
Speed Advisory
The Speed Advisory system allows
the driver to view posted speed
limits and advisory speed
information. This information comes
from the navigation map disc.
The navigation system only works
as well as the information provided
from that disc.
The navigation system uses GPS to
determine the vehicle’s location
within the navigation map disc. This
information is then downloaded
to the Speed Advisory message
area, which is located and displayed
in the DIC or HUD. See “DIC
Operation and Displays” and “Speed
Advisory” in the index of the
vehicle’s owner manual for more
information.
