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
(alternating) tone will be heard, and the
appropriate indicator lamp will flash. If
certain information such as vehicle identi-
fication number or customer information is
not available, the operator may need to
retransmit.
During this time you will hear a beep and
voice contact will be interrupted. Voice
contact will resume once the retrans-
mission is completed. Once a call is
concluded, a beep will be heard and the
respective indicator lamp will stop flash-
ing. The COMAND* system operation will
resume.
!
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
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.

If the indicator lamp continues to flash
or the system does not reset, contact
the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada), or
