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. If the indicator lamp on 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 tbutton on the
multifunction steering wheel or the
respective button for ending a
telephone call on the audio system or
the COMAND* headunit.
!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 an 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.

363 Operation
Maintenance
Resetting the maintenance service indicator
In the event that the maintenance service
on your vehicle is not carried out by an
authorized Mercedes-Benz Center, you can
have the maintenance service indicator
reset. The automotive maintenance facility
carrying out the maintenance service will
find the information for resetting the
maintenance service indicator in the
maintenance-relevant information for your
vehicle. Such information is available from
either your authorized Mercedes-Benz
Center or directly from Mercedes-Benz.
iIf the battery is disconnected, the days
of disconnection will not be included in
the count shown by the maintenance
service indicator. To arrive at the true
maintenance service deadline, you will
need to subtract these days from the
days shown in the maintenance service
indicator message or maintenance ser-
vice indicator display.
Do not confuse the maintenance
service indicator with the engine oil
level indicator:.
iIf the maintenance service indicator
was inadvertently reset, have an
authorized Mercedes-Benz Center
correct it.
Only reset if the proper maintenance
service has been performed. Resetting
the system without performing the
proper service as called for by the
maintenance service indicator will
result in engine damage and/or other
vehicle damage not covered by the
Mercedes-Benz Limited Warranty.
