Call priority
If other service calls such as a Roadside
Assistance call or Information call are
active, an Emergency call is still possible.
In this case, the Emergency call will take
priority and override all other active calls.
i
The indicator lamp in the Information
button
¡
remains illuminated in red
for approximately ten seconds during
the system self-check after switching
on the ignition (together with the
SOS button and the Roadside
Assistance button
•
).
See system self-check (
컄
page 282) if
the indicator lamp does not come on in
red or stays on longer than
approximately ten 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 avail-
able). The message
Call failed ap-
pears in the multifunction display.
Information calls can be terminated
using the
t
button on the multi-
function steering wheel or the END But-
ton on the Modular COMAND System.
!
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
malfunction or the service is not
currently active, and may not initiate a
call. Visit your authorized
Mercedes-Benz Light Truck 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.

nated by pressing button
t
