(only vehicles with COMAND).
Important!
If the indicator lamp continues to flash or the system 
does not reset, contact the Response Center at

When a Tele Aid call has been initiated, the audio 
system or the COMAND system audio (only vehicles

tape or CD) pauses. The optional cellular phone (if 
installed) switches off. If you must use this phone, the 
vehicle must be parked. Disconnect the coiled cord and

continue to run. The display in the instrument cluster is 
available for use and spoken commands are only 
available by pressing the RPT button on the COMAND 
unit. A pop-up window will appear in the COMAND
