Global Positioning
System (GPS)
If equipped, 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 in
the status bar.
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 0184 and
If the System Needs Service
0 184.
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.
.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 are installed on
the vehicle.
.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.

along with the system’s voice
recognition database. This
allows you to speak more
naturally when using voice
recognition.
Using Voice Recognition
Voice recognition becomes
available once the system has
been initialized. This begins
when the ignition is turned on.
Initialization may take a few
moments.1. Press
gon the steering
wheel controls to activate
voice recognition.
2. The audio system mutes and the system plays a
prompt.
3. Clearly speak one of the commands described in
this section.
A voice recognition system
prompt can be interrupted
while it is playing by
pressing
gagain. Once voice recognition is
started, both the infotainment
display and instrument cluster
show the selections and visual
dialog content. These displays
can be turned on or off in the
Tutorial Mode under Settings

207.
There are three voice prompt
modes supported:
.Informative verbal prompts:
This type of prompt will
provide more information
regarding the supported
actions.
.Short prompts: This type of
prompt will provide simple
instructions about what can
be stated.
.Auto informative prompts:
This type of prompt plays
during the first few speech
sessions, then automatically
switches to the short
prompt after some
experience has been gained
through using the system. If a command is not spoken,
the voice recognition system
says a help prompt.
Prompts and Infotainment
Displays
While a voice recognition
session is active, there may be
corresponding options
showing on the displays.
A selection can be made by
manually touching the option,
or by speaking the number for
the option to select. Manual
interaction in the voice
recognition session is
permitted. Interaction during a
voice session may be
completed entirely using voice
commands while some manual
commands may expedite a
task. If a selection is made
using a manual control, the
voice recognition dialog will
progress in the same way as if
the selection were made using
a voice command. Once the
system completes the task,
