cluster displayPractical hints Car care Index 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.

Important!
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 Client Assistance at

Customer Service at 1-800-387-0100 in Canada.
Notes:
The indicator lamp in the respective button f lashes until
the call is concluded and this can only be completed by
a Response Center or Client Assistance Center
representative.
When a Tele Aid call has been initiated, the audio
system 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. Disconnect the coiled cord and place
the call. Stolen vehicle tracking services
In the event your vehicle was stolen, report the incident
to the police who will issue a numbered incident report.
Pass this number on to the Mercedes-Benz Response
Center.
The Response Center will then attempt to covertly
contact the vehicle’s Tele Aid system. Once the vehicle
is located, the Response Center will contact the local
Law Enforcement and you. The vehicle’s location will
only be provided to Law Enforcement.
Important!
Tele Aid utilizes the cellular network for
communication and the GPS (Global Positioning
System) satellites for vehicle location. If either of these
signals are unavailable, the Tele Aid system may not
function and if this occurs, assistance must be
summoned by other means.
