Then press the volume button on your steering wheel to adjust the volume. To change the track or station, press the left or right arrow buttons. To mute the audio, press the mute button. To access your other audio sources, press the source button.

One important thing to note when using the steering wheel controls for your Audi A4 audio system is that the buttons may have different functions depending on the audio source you are currently using.
