133 Tele Aid
Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Emergency calls
An emergency call is initiated automatically:
•following an accident in which the Emergency
Tensioning Retractors (ETR’s) or airbags deploy,
•if the antitheft alarm or the tow away alarm stays on
for more than 20 seconds, see pages 35 and 37.
An emergency call can also be initiated manually by
opening the cover next to the inside rear view mirror
labeled “SOS”, then briefly pressing the button located
under the cover. See below for instructions on initiating
an emergency call manually.
Once the emergency call is in progress, the indicator
lamp in the “SOS” button will begin to flash. All
information relevant to the emergency, such as the
location of the vehicle (determined by the GPS satellite
location system), vehicle model, identification number
and color are generated.
A voice connection between the Response Center and
the occupants of the vehicle will be established
automatically soon after the emergency call has been
initiated. When a voice connection is established the
audio system mutes. The Response Center will attempt
to determine more precisely the nature of the accident
provided they can speak to an occupant of the vehicle.The Tele Aid system is available if:
•it has been activated and is operational. Activation
requires a subscription for monitoring services and
cellular air time
•the relevant cellular phone network and GPS signals
are available and pass the information on to the
Response Center.
Note:
Location of the vehicle on a map is possible if the
vehicle is able to receive signals from the GPS satellite
network and pass the information on to the Response
Center.
Wa r n i n g !
If the indicator lamp in the “SOS” button is
illuminated continuously and there was no voice
connection to the Response Center established,
then the Tele Aid system could not initiate an
emergency call (e.g. the relevant cellular phone
network is not available).Should this occur, assistance must be summoned
by other means.

cluster displayPractical hints Car care Index 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
1-800-FOR-MERCedes (1-800-367-6372) in the USA or
Customer Service at 1-800-387-0100 in Canada.
Notes:
The indicator lamp in the respective button flashes 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.
