Voice Recognition
If equipped, voice recognition allows
for hands-free operation within the
audio and phone applications. This
feature can be started by pressing
either the
gbutton on the steering
wheel or by selecting the
gon the
screen display.
However, not all features within
these areas are supported by voice
commands. Generally, only complex
tasks that require multiple manual
interactions to complete are
supported by voice commands.
For example, tasks that take more
than one or two button presses such
as selecting a song or artist to play
from a media device would be
supported by voice commands.
Other tasks, like adjusting the
volume or seeking up or down are audio features that are easily
performed by pressing one or two
buttons, and are not supported by
voice commands.
In general there are flexible ways to
speak commands for completing the
tasks. Most of them, except
destination entry and voice keypad,
can be completed in a single
command. If the task takes more
than one command to complete, the
first command would be to indicate
the kind of task that is to be
performed. The system replies with
prompts that lead through a dialog
to enter the necessary information.
Voice recognition can be used when
the ignition is on or when Retained
Accessory Power (RAP) is active.
See
Retained Accessory Power
(RAP) on page 9-28.

7-26 Infotainment System
Canceling Voice Recognition
.Press the Home screen button
to terminate the voice
recognition session which was
initiated by pressing
gon the
infotainment screen on the
center stack.
.Press or say “Cancel”or“Exit” to
terminate the voice recognition
session and display the screen
from which voice recognition
was initiated.
.Pression the steering wheel
controls to terminate the voice
session and display the screen
from which voice recognition
was initiated.
Helpful Hints for Speaking
Commands
Voice recognition can understand
commands that are either naturally
stated in sentence form (English
only), or direct commands that state
the application and the task. For languages that do not support
natural language commands in
sentence form, use the direct
commands shown as examples on
the display screen.
For best results:
.Listen for the prompt and wait
for the beep before saying a
command or reply.
.Say
“Help” or look at the screen
display for commands.
.Voice recognition system prompt
can be interrupted during a
prompt by pressing
gagain.
For example, if the prompt
seems to be taking too long to
finish, or if what is being
prompted causes a need for an
immediate reply, press
gagain
and wait for the beep.
.Speak the command naturally,
not too fast, not too slow. Use
direct commands without a lot of
extra words.
.Usually Phone and Audio
commands can be spoken in a
single command.
For example, “Call Dave Smith
at work,” “Play” followed by the
artist or song name, or “Tune”
followed by the radio station
number.
There is no need to memorize
specific command words. Direct
commands might be more clearly
understood by the system. An
example of a direct command would
be “Call 555-1212.” Examples of
these direct commands are
displayed on most of the screens
while a voice session is active.
If “Phone” or“Phone Commands,” is
stated, the system understands that
a phone call is requested and will
respond with questions until enough
details are gathered.
If the phone number has been
saved with a name and a place, the
direct command should include
both, for example “Call Dave Smith
at work.”

Bluetooth (Overview)
Instructions for using the cell phone
may differ between infotainment
systems. The base radio and base
radio with connectivity instructions
are included in this manual. See the
infotainment manual for instructions
on the uplevel radios.
Bluetooth-capable systems can
interact with many cell phones,
allowing:
.Placement and receipt of calls in
a hands-free mode.
.Sharing of the cell phone’s
address book or contact list with
the vehicle.
To minimize driver distraction,
before driving, and with the vehicle
parked:
.Become familiar with the
features of the cell phone.
Organize the phone book and
contact lists clearly and delete duplicate or rarely used entries.
If possible, program speed dial
or other shortcuts.
.Review the controls and
operation of the infotainment
system.
.Pair cell phone(s) to the vehicle.
The system may not work with
all cell phones. See
“Pairing”in
this section.
.If the cell phone has voice
dialing capability, learn to use
that feature to access the
address book or contact list. See
“Voice Pass-Thru” in this
section.
.See “Storing and Deleting Phone
Numbers” in this section.
{Warning
When using a cell phone, it can
be distracting to look too long or
too often at the screen of the
phone or the infotainment system.

Warning (Continued)
Taking your eyes off the road too
long or too often could cause a
crash resulting in injury or death.
Focus your attention on driving.
Vehicles with a Bluetooth system
can use a Bluetooth-capable cell
phone with a Hands-Free Profile to
make and receive phone calls. The
infotainment system and voice
recognition are used to control the
system. The system can be used
while in ON/RUN or ACC/
ACCESSORY. The range of the
Bluetooth system can be up to 9.1 m
(30 ft). Not all phones support all
functions and not all phones work
with the Bluetooth system. See
www.gm.com/bluetooth for more
information about compatible
phones.
