The indicator lamp in the Information
button ¡ remains illuminated in red for
approximately 10 seconds during the system
self-check after switching on the ignition (togeth-
er with the SOS button and the Roadside
Assistance button •).
See system self-check ( page 309) if the indi-
cator 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 cel-
lular phone network is not available). The mes-
sage Call failed appears in the multifunction
display.
Information calls can be terminated using
the t button on the multifunction steering
wheel or the END button on the COMAND sys-
tem.

If the indicator lamps do not start flashing
after pressing one of the buttons or remain illu-
minated (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.

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.

sentative, whereas Roadside Assistance and
Information calls can also be terminated by

steering wheel or using the END button on the
COMAND system.
