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 Navigation
The on-screen menu can be controlled using the navigation buttons on the reverse of the steering wheel (16/46).
The buttons consist of:
- an enter button
- a back button
- a control button that can move the marker on the screen up, down, left and right.
The commands are transmitted from the Steering wheel module (SWM) (3/254) via CAN to the Central electronic module (CEM) (4/56) and on to the Infotainment control module (ICM) (3/281) on the CAN network. The Steering wheel module (SWM) converts the electrical signal to an optical signal and sends it on 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.
