If your vehicle has this feature, some audio controls can be adjusted at the steering wheel. They include the following:

(Seek): Press the seek arrows to go to the next or to the previous radio station. The radio seeks stations only with a strong signal that are in the selected band. To scan stations, press and hold either arrow for two seconds until a beep sounds. The radio goes to a station, play for a few seconds, then goes to the next station. Press either seek arrow again to stop scanning. While a CD is playing, press the seek arrows to go to the next or previous track.

(Mute/OnStar®): Press this button to silence the system. Press this button again, or any other radio button, to turn the sound on. If your vehicle has OnStar®, press and hold this button for more than two seconds to interact with the OnStar® system. See the OnStar® System in this manual for more information.

BAND: Press this button to switch between FM1, FM2, AM, or XM1™ or XM2™ (if equipped).

The radio seeks preset stations only with a strong signal that are in the selected band. When a CD is playing in the six-disc CD changer, press this button to go to the next available CD, if multiple CDs are loaded.
