Roadside Assistance button 
Located below the center armrest cover is the Roadside
Assistance button. Pressing and holding the
button (for longer than 2 seconds) will initiate a call to a
Mercedes-Benz Roadside Assistance dispatcher. The
button will flash while the call is in progress. The
message “ROADSIDE ASSISTANCE – CONNECTING
CALL” will appear in the multifunction display. When
the connection is established, the message “ROADSIDE
ASSISTANCE – CALL CONNECTED” appears in the
multifunction display. The Tele Aid system will transmit
data generating the vehicle identification number,
model, color and location (subject to availability of
cellular and GPS signals).A voice connection between the Roadside Assistance
dispatcher and the occupants of the vehicle will be
established. When a voice connection is established the
audio system mutes and the message “TELE AID –
ROADSIDE ASSISTANCE CALL ACTIVE” appears in the
multifunction display. The nature of the need for
assistance can then be described. The Mercedes-Benz
Roadside assistance dispatcher will either dispatch a
qualified Mercedes-Benz technician or arrange to tow
your vehicle to the nearest Mercedes-Benz Center.
For services such as labor and/or towing charges may
apply. Refer to the Roadside Assistance manual for more
information.
These programs are only available in the USA:
•Sign and Drive services: Services such as jump start,
a few gallons of fuel or the replacement of a flat tire
with the vehicle spare tire are obtainable,
•Remote Vehicle Diagnostics: This function permits
the Mercedes-Benz Roadside Assistance dispatcher
to download malfunction codes and actual vehicle
data.
Wa r n i n g !
If you feel at any way in jeopardy when in the
vehicle (e.g. smoke or fire in the vehicle, vehicle in
a dangerous road location), please do not wait for
voice contact after you have pressed the emergency
button. Carefully leave the vehicle and move to a
safe location. The Response Center will
automatically contact local emergency officials
with the vehicle’s approximate location if they
receive an automatic “SOS” signal and cannot make
voice contact with the vehicle occupants.
