The Tele Aid system processes calls using
the following priority:
ț Automatic emergency – First priority
ț Manual emergency – Second priority
ț Roadside Assistance – Third priority
ț Information – Fourth priority
Should a higher priority call be initiated
while you are connected, an upgrade (al-
ternating) tone will be heard, and the ap-
propriate indicator lamp will flash. If
certain information such as vehicle identi-
fication number or customer information is
not available, the operator may need to re-
transmit.
During this time you will hear a beep and
voice contact will be interrupted. Voice
contact will resume once the retransmis-
sion is completed. Once a call is conclud-
ed, a beep will be heard and the respective
indicator lamp will stop flashing. The
COMAND system operation will resume.

The indicator lamp in the Information
button
¡ remains illuminated in red
for approximately ten seconds during
the system self-check after turning the
ignition on (together with the SOS but-
ton and the Roadside Assistance
button
•).
See System self-check ( ୴ page 231)
when the indicator lamp does not come
on in red or stays on longer than ap-
proximately ten seconds.
If the indicator lamp in the Information
button
¡ is illuminated continuous-
ly 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 avail-
able). The message
INFO –
CALL FAILED appears in the multifunc-
tion display.
Information calls can be terminated us-
ing the
tbutton on the multifunc-
tion steering wheel.
!
If the indicator lamps do not start flash-
ing after pressing one of the buttons or
remain illuminated (in red) at any time,
the Tele Aid system has detected a
fault or the service is not currently ac-
tive, and may not initiate a call. Visit an
authorized 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.
