Call priority
If other service calls such as a Roadside
Assistance call or Information call are ac-
tive, an Emergency call is still possible. In
this case, the Emergency call will take pri-
ority and override all other active calls.
i
The indicator lamp in the Information
button ¡ remains illuminated in red for
approximately 10 seconds during the system
self-check after switching on ignition (together
with the SOS button and the Roadside
Assistance button •).
See “System self-check” (
୴ page 263) when the
indicator lamp does not come on in red or stays
on longer than approximately 10 seconds.
If the indicator lamp in the Information
button ¡ is flashing continuously and there
was no voice connection to the Response Center
established, then the Tele Aid system could not
initiate an Information call (e.g. the relevant
cellular phone network is not available).
The message
Call Failed
appears in the
multifunction display.
Information calls can be terminated using the
button
t on the multifunction steering
wheel or the respective button for ending a
telephone call on the audio system or COMAND*
head unit.
!
If the indicator lamps do not start flashing
after pressing one of the buttons or remain
illuminated (in red) at any time, the Tele Aid
system has detected a malfunction or the
service is not currently active, and may not
initiate a call. Visit your Mercedes-Benz Center
and have the system checked or contact the
Response Center at 1-800-756-9018 (in the
USA) or 1-888-923-8367 (in Canada) as soon as
possible.

The indicator lamp in the respective button

or the respective button for ending a telephone
call on the audio system or COMAND* head unit.
