Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Menu Control
The on-screen menu can be controlled using the buttons on the reverse of the steering wheel.
The buttons consists of:
- a Back button
- an Enter button
- a navigation button which is used to move the cursor up, down, left and right on the screen.
The steering wheel module (SWM) (3/254) transmits a signal to the infotainment control module (ICM) (16/1) via the controller area network (CAN).
The infotainment control module (ICM) converts the electrical signal to an optical signal and sends it onwards to the multimedia module (MMM) (16/108) via the MOST network.
The remote control for the multimedia module (MMM) has the same functions as the steering wheel buttons. The remote control can be used to control the menus on the display screen. The IR signal is transmitted from the remote control to an IR receiver which is mounted in the loudspeaker grille on the dashboard. The receiver transmits the signal to the multimedia module (MMM) via the infotainment control module (ICM).
