Vehicles with audio steering wheel controls could differ depending on your vehicle's options. Some audio controls can be adjusted at the steering wheel. They include the following:

(Mute/Voice Recognition): Press and release this button to silence the vehicle speakers only. The audio of the wireless and wired headphones, if your vehicle has these features, does not mute. Press and release this button again, to turn the sound on. If your vehicle has the navigation system, press and hold this button for longer than one second to initiate voice recognition. See "Voice Recognition" in the Navigation System manual for more information. If your vehicle has OnStar®, press and hold this button for longer than one second to interact with the OnStar® system. If your vehicle also has the navigation system, press and hold this button for longer than one second to initiate voice recognition and say "OnStar" to enter OnStar® mode. See the OnStar® System in this manual for more information.
