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 on the map screen.
See Navigation Symbols 0 158.
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.
For more information if the GPS is not
functioning properly, see Problems
with Route Guidance 0 165 and
If the System Needs Service 0 166.

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 sand, gravel,
or snow.
The vehicle is traveling 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.
The vehicle has been transferred by
a vehicle carrier or a ferry.
The current position calibration is
set incorrectly.
The vehicle is traveling at high
speed.
The vehicle changes directions more
than once, or the vehicle is turning
on a turn table in a parking lot.
INFOTAINMENT SYSTEM
The vehicle is entering and/or
exiting a parking lot, garage, or a lot
with a roof.
The GPS signal is not received.
A roof carrier is installed on the
vehicle.
Tire chains have been installed.
The tires are replaced or worn.
The tire pressure for the tires is
incorrect.
This is the first navigation use after
the map data is updated.
The 12-volt battery has been
disconnected for several days.
The vehicle is driving in heavy
traffic where driving is at low
speeds, and the vehicle is stopped
and started repeatedly.
