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 Audio
Steering Wheel Controls on page 3-127 for more
information.
b g (Push To Talk): Press to answer incoming calls,
to confirm system information, and to start speech
recognition.
c x (Phone On Hook): Press to end a call, reject a
call, or to cancel an operation.
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.
