The steering wheel buttons connected to the steering wheel module (SWM) (3/130) can be used to control:

• Volume control and CD track / radio selection
• Menu selection for traffic information
• volume control during hands free carphone calls and menu selection for the phone module (PHM) (16/60)
• volume control for Television Module (TVM) (16/36) (option)
• volume control for Rear seat entertainment module (RSE) (16/109) (only XC60) (option)

The signals from the steering wheel buttons are transmitted to the steering wheel module (SWM) (3/130) with LIN communication. The steering wheel module (SWM) transmits the signals on to the Infotainment Control Module (ICM) (3/281) using LIN communication. The infotainment control module (ICM) in turn transmits the signals on to the affected control module on the MOST network.
