If the indicator lamp in the Information button
¡ is
illuminated 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).
Important!
If the indicator lamps do not start flashing after 
pressing one of the buttons or remain illuminated (in 
red) at any time, the Tele Aid system has detected a fault 
or the service is not currently active, and may not 
initiate a call. Visit your 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.
Upgrade Signals
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 (alternating) tone will be heard, 
and the appropriate indicator lamp will flash. If certain 
information such as vehicle identification number or 
client information is not available, the operator may 
need to retransmit. During this time you will hear a 
chirp and voice contact will be interrupted. Voice 
contact will resume once the retransmission is 
completed. Once a call is concluded, a chirp will be 
heard and the appropriate indicator lamp will stop 
flashing. The audio system operation will resume.
