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.
Right-Hand Keypad
The right-hand keypad unit is on the right-hand side of the infotainment control module (ICM). The keypad is connected via a cable directly to the printed circuit board. The keypad unit has the following buttons:
- button for sound control
- button for carphone on/off
- button for selecting the function, can be programmed by the user
- buttons for the carphone and menu control
- SIM card holder
- button for CD ejection
- knob to select the source.
The buttons are connected in button circuits. When a button is pressed the circuit closes. The infotainment control module determines which button is pressed by the voltage level of the input signal from the circuit. The table below outlines which buttons are in the different circuits.
| Button circuit | Button | |||

The SIM card holder is connected via a directly connected cable to the phone module (PHM). It is not connected to the infotainment control module (ICM).
