2003-2005 Generation 5 OnStar Steering Wheel Control Function - kw mute OPC operation performance radio UA1 UE1 volume SWC steering wheel vs3bgen5 voicerec

The following diagnosis might be helpful if the vehicle exhibits the described symptoms in the PI.

Some 2003 and 2005 GM vehicles equipped with the OnStar Generation 5 system have Steering Wheel Controls (SWC) that can be used in conjunction with the OnStar Personal Calling Voice Recognition system.

Here is how the Steering Wheel Controls function on vehicles with OnStar voice recognition and Steering Wheel Controls.

1. On the following vehicles, the push-to-talk button invokes the voice recognition feature. A subsequent press will re-invoke voice recognition for use with a voice mail system, or other system which may require tones to be transmitted, such as dialing an extension after reaching an office phone system. Saying the word "dial" will transmit the tone(s) associated with the digits entered. Subsequent presses of the button will re-invoke the voice recognition system and the process repeats. Pressing the "white dot " or "End" button will exit voice mode if a call has not been placed. To disconnect from the call press the "white dot " or the "end" button on the steering wheel.
2. To answer a incoming call the "White dot button" must be used when the subscriber hears the radio mute and the system start ringing. Calls can only be ended by the "White dot button" or the "End" button on the steering wheel (If equipped).

NOTES:

1. Consult the specific OnStar owners manual or SI for proper operation of the steering wheel controls.
2. NAV or the UV8 cell phone button functions differ and/or are disabled for OnStar functions. Consult the specific vehicle owner manual for proper operation.
