Upgrade Signals
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 ap-
propriate indicator lamp will flash. If 
certain information such as vehicle identi-
fication number or customer information is 
not available, the operator may need to re-
transmit.
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 conclud-
ed, a beep will be heard and the 
appropriate indicator lamp will stop flash-
ing. The COMAND system operation will 
resume.
!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 
Mercedes-Benz Customer Assistance 
at 1-800-FOR-MERCedes 
(1-800-367-6372) in the USA or Cus-
tomer Service at 1-800-387-0100 in 
Canada.iThe indicator lamp in the respective 
button flashes until the call is conclud-
ed. Calls can only be terminated by a 
Response Center or Customer Assis-
tance Center representative except 
Roadside Assistance and Information 
calls, which can also be terminated by 
pressing button
ì 
on the multifunc-
tion steering wheel.
iWhen a Tele Aid call has been initiated, 
the audio system or the COMAND sys-
tem audio is muted and the selected 
mode (radio, tape or CD) pauses. The 
optional cellular phone (if installed) 
switches off. If you must use this 
phone, the vehicle must be parked. Dis-
connect the coiled cord and place the 
call. The COMAND navigation system 
(if engaged) will continue to run. The 
display in the instrument cluster is 
available for use and spoken com-
mands are only available by pressing 
the RPT button on the COMAND unit. A 
pop-up window will appear in the CO-
MAND display to indicate that a 
Tele Aid call is in progress.
