The Tele Aid system processes calls using
the following priority:
Automatic emergency - First priority
Manual emergency - Second priority
Roadside Assistance - Third priority
Information - Fourth priority
Should a higher priority call be initiated
while you are connected, an upgrade (al-
ternating) tone will be heard, and the
appropriate indicator lamp flashes. If
certain information such as vehicle iden-
tification number or customer informa-
tion 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 retransmis-
sion is completed. Once a call is included,
a beep will be heard and the respective
indicator lamp will stop flashing. The
COMAND system operation will resume.
i
The indicator lamp on the Informa-
tion button ¡ remains illuminated
in red for approximately 10 seconds
during the system self-check after
switching on ignition (together with
the SOS button and the Roadside As-
sistance button •).
See system self-check (
page 295)
when the indicator lamp does not
come on in red or stays on longer
than approximately 10 seconds.
If the indicator lamp on the informa-
tion button ¡ is illuminated con-
tinuously and there was no voice
connection to the Response Center
has been established, then the Tele
Aid system could not initiate an Infor-
mation call (e.g. the relevant cellular
phone network is not available).
The message
INFO
CALL FAILED
appears in the multifunction display.
Information calls can be terminated
using the t button on the multi-
function steering wheel or the re-
spective button for ending a
telephone call on the COMAND head-
unit.
!
If the indicator lamps do not start
flashing after pressing one of the but-
tons or remain illuminated (in red) at
any time, the Tele Aid system has de-
tected a malfunction or the service is
not currently active, and may not ini-
tiate a call. Visit your Maybach Studio
and have the system checked or con-
tact the Maybach Assistance Center
at 1-866-FOR-MAY-Bach (in the USA)
or 1-888-881-6611 (in Canada) as
soon as possible.
