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

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.
