Automatic central locking
With the automatic central locking system activated, the
doors and trunk are locked at vehicle speeds of
approximately 9 mph (15 km / h) or more. The fuel filler
flap remains unlocked.
The automatic central locking function can be switched
on or off in the individual setting menu “VEHICLE” –
“AUTOMATIC DOOR LOCK”, see page 146.
Notes:
If doors are unlocked with the central locking switch
after activating the automatic central locking, and
neither door is opened, then the doors remain unlocked
even at vehicle speeds of approximately 9 mph
(15 km / h) or more.
If a door is opened from the inside at speeds of
approximately 9 mph (15 km / h) or less with the
automatic central locking activated, the door will again
be automatically locked at speeds of approximately
9 mph (15 km / h) or more.
When a door is opened from the inside, the complete
vehicle is unlocked, if the vehicle is previously unlocked
in the global remote control mode.Important!
When towing the vehicle, or with the vehicle on a
dynamometer test stand, please, note the following:
With the automatic central locking activated and the
electronic key in starter switch position 2 (vehicles with
KEYLESS-GO: operation position, see page 236), the
vehicle doors will lock if the left front wheel as well as
the right rear wheel spin at vehicle speeds of
approximately 9 mph (15 km / h) or more.
Emergency unlocking in case of accident
The doors unlock automatically a short time after an
accident in which an airbag or emergency tensioning
retractor deploys (this is intended to aid rescue and
exit).

62 Tow-away alarm

The alarm will last approximately 2
1/2minutes in form
of flashing exterior lamps. At the same time an alarm
will sound for 30 seconds. The alarm will stay on even if
the vehicle is immediately lowered. To cancel the alarm,
insert the electronic key in the starter switch or press
buttonŒ or‹ on the electronic key; or (vehicles
with KEYLESS-GO) when carrying the KEYLESS-GO-
card, grasp the door handle or press the start-/stop
button on the gear selector lever.
If the alarm stays on for more than 20 seconds, an
emergency call is initiated automatically. See Tele Aid
on page 218.To prevent triggering the tow-away alarm feature, switch
off the tow-away alarm before towing the vehicle, or
when parking on a surface subject to movement, such
as a ferry or auto train.
To do so, turn electronic key in starter switch to
position 1 or 0, or remove electronic key from starter
switch. Press tow-away alarm switch (1). The indicator
lamp (2) illuminates briefly.
Exit vehicle, and lock vehicle with the electronic key or
(vehicles with KEYLESS-GO) the lock button at each
door handle.
The tow-away alarm remains switched off until the
vehicle is locked again with the electronic key or the
lock button at each door handle (vehicles with
KEYLESS-GO), at which time it is automatically
reactivated.

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.
