Function description:  
      For better operation of radio and telephone 
system while driving, six function keys are 
integrated into the steering wheel. In addition, the 
multi-function steering wheel is electrically 
heated.  
      The electronics in the steering wheel take over 
the regulation of the steering wheel heating, 
transmission of the six function buttons to CAN-
bus and dimming of the function buttons. The 
electronics in the steering wheel cannot be 
replaced individually, the entire steering wheel 
must be replaced in case of a malfunction.  
      The control module of the multi-function steering 
wheel takes over control of the radio (or 
radio/navigation system), telephone system, 
instrument cluster, and steering wheel heating.  
      In the center display of the instrument cluster, the 
selected station appears during radio operation 
and the name and telephone number of the 
dialogue partner from the telephone memory 
appears during telephone operation. If a cassette 
is inserted during radio operation, the message 
"TAPE    " appears and for CD-operation, CD-
number "CD 02" and the respective title (track) 
"TR 09" appears on the center display.
