OnStar® button on the mirror then use the volume buttons on the SWC to adjust the level. The volume will raise a total of 10
times before returning to the original level.
5. Verify that the factory XM tuner is functioning properly.

turn back on and the OnStar® LED will turn off. Pressing the Mute/OnStar® button on the steering wheel for 1.5 seconds will
also activate OnStar®.
