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.
Left-Hand Keypad
The left-hand keypad unit is on the left-hand side of the infotainment control module. The keypad is connected via a cable directly to the printed circuit board. The keypad unit has the following buttons:
- ON/OFF button
- buttons for direct access to the CD player and radio
- buttons for searching on the CD player and radio
- numeric buttons for the carphone, CD selection and preprogrammed radio stations
- a knob for the volume control
- an infrared receiver for remote control.
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 | |||
| Button circuit 1 | ||||
| Button circuit 2 | ||||
| Button circuit 3 | ||||
