7-52 Infotainment System
Voice Recognition
The Bluetooth system uses voice
recognition to interpret voice
commands to dial phone numbers
and name tags.
For additional information, say
Help while you are in a voice
recognition menu.
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.
Bluetooth Controls
Use the buttons located on the
steering wheel to operate the in
vehicle Bluetooth system. See
Steering Wheel Controls on
page 5 3 for more information.
/ (Push To Talk): Press to
answer incoming calls, confirm
system information, and start
speech recognition.
/ (End): Press to end a call,
reject a call, or cancel an operation.
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
the cell phone manufacturer's 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 equipped. See OnStar
Overview on page 14 1 for more
information.
Pairing Information
A Bluetooth phone with MP3
capability cannot be paired to
the vehicle as a phone and an
MP3 player at the same time.
Up to five cell phones can be
paired to the Bluetooth system.
The pairing process is disabled
when the vehicle is moving.
