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 Symbols on page 5‑17.
This system may not be available or interferences may
occur if any of the following are true:
.Signals are obstructed by tall buildings, trees, large
trucks, or a tunnel.
.Objects are located on the front dash of the
vehicle.
.Satellites are being repaired or improved.
.After-market glass tinting has been applied to the
vehicle's windshield.
5-56
Page 327 of 580

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 If the System Needs Service
on
page 5‑58and Problems with Route Guidanceon
page 5‑58.
Vehicle Positioning
At times, the position of the vehicle on the map may be
inaccurate due to one or more of the following reasons:
.Road system has changed.
.Vehicle is driving on slippery road surfaces such as
in sand, gravel, and/or snow.
.Vehicle is traveling on winding roads.
.Vehicle is on a long straight road.
.Vehicle is approaching a tall building or a large
vehicle.
.Surface streets run parallel to a freeway.
.Vehicle has just been transferred by a vehicle
carrier or a ferry.
.Current position calibration is set incorrectly.
.Vehicle is traveling at high speed.
.Vehicle changes directions more than once,
or when the vehicle is turning on a turn table
in a parking lot.
.Vehicle is entering and/or exiting a parking lot
or a garage.
.GPS signal is not received.
.Roof carrier is installed on the vehicle.
.Vehicle is being driven with tire chains.
.Tires are replaced.
.Tire pressure for the tires is incorrect.

low speeds, and the vehicle is stopped and started
repeatedly.
See your dealer/retailer if other problems occur.
