iWhen a Tele Aid call has been initiated, the
COMAND system audio is muted and the select-
ed mode (radio, CD etc.) pauses. The optional

ommend that you use it only with the vehicle at a

able by pressing the RPT button on the COMAND

necessary.Warning!G
If the indicator lamps on the SOS button, on
the Roadside Assistance button, and/or on
the Information button remain illuminated
continuously in red and/or the message
Tele Aid – inoperative is displayed in
the multifunction display after the system
self-check, a malfunction in the system has
been detected.
If a malfunction is indicated as outlined
above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.
