Prompts and Screen Displays
While a voice recognition session is

command. Once the system is able
to complete the task, or the session
is terminated, the voice recognition
dialog stops.
An example of this type of manual
intervention is pressing on an entry
of a displayed number list instead of
speaking the number associated
with the entry desired.

Infotainment System 7-31
Phone
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.
(Continued)
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.

Pairing
A Bluetooth-enabled cell phone
must be paired to the Bluetooth
system and then connected to the
vehicle before it can be used. See
your cell phone manufacturer's user
guide for Bluetooth functions before
pairing the cell phone. If a Bluetooth
phone is not connected, calls can
be made using OnStar Hands-Free
Calling, if available. See OnStar
Overview on page 14-1, if equipped.
Pairing Information
.Up to five cell phones can be
paired to the Bluetooth system.
.The pairing process is disabled
when the vehicle is moving.
.Pairing only needs to be
completed once per phone,
unless the pairing information on the cell phone changes or the
cell phone is deleted from the
system.
.Only one paired cell phone can
be connected to the Bluetooth
system at a time.
.If multiple paired cell phones are
within range of the system, the
system connects to the first
available paired cell phone in the
order that they were newly
paired to the system. To connect
to a different paired phone, see
“Connecting to a Different
Phone”
later in this section.

manufacturer's user guide for
information on this process.
5. Locate the device named “Your
Vehicle” in the list on the cell
phone. Follow the instructions
on the cell phone to enter the
PIN provided in Step 3. If a six
digit code is shown on the phone
and the vehicle screen, confirm
the codes are the same. The
