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

(Next/Previous): Press the down or up arrow to go to the next or to the previous radio station stored as a favorite. When a CD is playing, press the down or up arrow to go to the next or to the previous track. If your vehicle has OnStar®, press the down arrow button to end an OnStar Hands-Free Call or the Advisor Playback. It also cancels or hangs-up an incoming Hands-Free Call.

(Mute/Voice Recognition): Press and release this button to silence the system. 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 this button to initiate voice recognition and say "OnStar" to enter OnStar mode. See the OnStar® System in this manual for more information.

SRCE (Source): Press this button to switch between AM, FM, XM™ (if equipped), CD, and auxiliary input jack.

+  - (Volume): Press the plus or minus volume button to increase or to decrease the radio volume.

(Seek): Press the seek arrow to go to the next radio station and stay there.

If you have the navigation system, some of the audio steering wheel controls work when a CD is playing in the navigation radio. See the Navigation System manual for more information.
