Navigation/Radio System
For vehicles with a navigation radio system, see the
separate Navigation System manual.
Bluetooth®
Vehicles with a Bluetooth system can use a Bluetooth
capable cell phone with a Hands Free Profile to make
and receive phone calls. The system can be used while
the key is in ON/RUN or ACC/ACCESSORY position.
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 are guaranteed to work with the in-vehicle
Bluetooth system. See www.gm.com/bluetooth for more
information on compatible phones.
Voice Recognition
The Bluetooth system uses voice recognition to
interpret voice commands to dial phone numbers and
name tags.
Noise : Keep interior noise levels to a minimum. The
system may not recognize voice commands if there is
too much background noise.
When to Speak : A short tone sounds after the system
responds indicating when it is waiting for a voice
command. Wait until the tone and then speak.
How to Speak : Speak clearly in a calm and natural
voice.
Audio System
When using the in‐vehicle Bluetooth system, sound
comes through the vehicle's front audio system
speakers and overrides the audio system. Use the
audio system volume knob, during a call, to change the
volume level. The adjusted volume level remains in
memory for later calls. To prevent missed calls, a
minimum volume level is used if the volume is turned
down too low.

Pairing
A Bluetooth enabled cell phone must be paired to the
in‐vehicle Bluetooth system first and then connected to
the vehicle before it can be used. See the cell phone
manufacturers user guide for Bluetooth functions before
pairing the cell phone. If a Bluetooth phone is not
connected, calls will be made using OnStar
®
Hands‐Free Calling, if available. Refer to the OnStar
owner's guide for more information. Pairing Information:
.Up to five cell phones can be paired to the
in‐vehicle Bluetooth system.
.The pairing process is disabled when the vehicle is
moving.

with the first available paired cell phone in the
order the phone was paired.
.Only one paired cell phone can be connected to
the in‐vehicle Bluetooth system at a time.
.Pairing should only need to be completed once,
unless changes to the pairing information have
been made or the phone is deleted.
To link to a different paired phone, see Linking to a
Different Phone later in this section.
