Multifunction steering wheel shown
General information
The multifunction steering wheel serves to increase active driving safety in road traffic in combination with the instrument cluster (A1). This allows the driver to concentrate on the traffic without distraction when controlling and operating various vehicle components (for example: CD changer, telephone).
The multifunction steering wheel allows the driver to control and call up the following systems without taking his hands off the steering wheel:
- COMAND
- CD changer
- Cassette player
- Telephone/voice control system
- Navigation
- Trip computer
- Settings (setting time, shutoff delay for interior lighting, ...)
The main system selected by the driver is displayed in the multifunction display (A1p13) on the instrument cluster (A1). The fanfare horns can also be actuated via the steering wheel impact plate (1).
Keypad
Each of the systems can be actuated using the system selection button (S110s3). Each press of the button opens the next system screen in the multifunction display (A1p13). It is not possible to move backwards.
If necessary, the system selection button must be pressed repeatedly until the desired system reappears in the multifunction display (A1p13).
It is possible to "scroll" in a system with the scroll forward/back button (S110s1) to open additional submenus.
The voice control system (VCS) can also be switched on and off using the system selection and voice control system button (S110s3).
With the buttons:
- For accepting or terminating a call (S111s3) it is possible to accept (answer) or terminate (hang up) a call.
- "+" and "a" for setting specific functions and for volume control (S111s1), the volume of a currently active system can be changed.
It is also possible to adjust the interior light OFF delay time, for example, using the "+" (increase) and "a" (decrease) buttons.
The control signals are transmitted from the keypad on the steering wheel via the clock spring contact to the control unit located in the steering column module (N80).
The signals are transmitted from the steering column module (N80) via the vehicle's own bus system (interior CAN) to the instrument cluster (A1). Depending on the system shown in the display, a CAN signal for the required component (CD changer, telephone...) is generated and transmitted from here. In the COMAND operating, display and control unit (A40/3), the CAN signal is converted in such a way that the Digital Data Bus system (D2B) can relay the signals to the required device (CD changer, telephone...).
