Emergency calls
An emergency call is initiated automatical-
ly:
following an accident in which the
emergency tensioning devices (ETDs)
or airbags deploy
if the anti-theft alarm or the tow-away
alarm stays on for more than
20 seconds. See anti-theft alarm sys-
tem (
page 82) and tow-away alarm
(
page 82)
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. The message
EMERGENCY CALL –
CONNECTING CALL
appears in the multifunc-
tion display. When the connection is estab-
lished, the message
EMERGENCY CALL –
CALL CONNECTED
appears in the multifunc-tion display. All information relevant to the
emergency, such as the location of the ve-
hicle (determined by the GPS satellite loca-
tion 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 af-
ter the emergency call has been initiated.
When a voice connection is established,
the audio system is muted and the mes-
sage
TELE AID – EMERGENCY CALL ACTIVE
appears in the multifunction display. The
Response Center will attempt to determine
more precisely the nature of the accident
provided they can speak to an occupant of
the vehicle.
!If the indicator lamps in the
SOS button, in the "Roadside
Assistance" button and in the
"Information" button remain illuminat-
ed constantly in red and/or the mes-
sage
TELE AID – VISIT WORKSHOP!
is
displayed in the multifunction display
after the system self-check, a malfunc-
tion in the system has been detected.
If a malfunction is indicated as outlined
above, the system may not operate as
expected. Have the system checked at
the nearest Mercedes-Benz Center as
soon as possible.

348 Practical hintsTowing the vehicle
Towing the vehicleTowing the vehicle
Mercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment.
When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the
ground or front wheels raised only so far as to have the vehicle moved to a safe loca-
tion where the recommended towing
methods can be employed.
!Use flatbed or wheel lift/dolly equip-
ment with key in starter switch turned
to position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts.
Switch off the tow-away alarm and the
automatic central locking
!If the vehicle is towed with the front
axle raised, the engine must be shut off
(key in starter switch position0 or1).
Otherwise, the ESP will immediately be
engaged and will apply the rear wheel
brakes.
When towing the vehicle with all wheels
on the ground, the selector lever must
be in positionN and the key must be in
starter switch position2. When towing
the vehicle with all wheels on the
ground, the vehicle may be towed only
for distances up to 30 miles (50 km)
and at a speed not to exceed 30 mph
(50 km/h).
!To be certain to avoid a possibility of
damage to the transmission, however,
we recommend the drive shaft be dis-
connected at the rear axle drive flange
for any towing beyond a short tow to a
nearby garage.
