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 83) and tow-away alarm
(
page 85)
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover.
For more information, see “Initiating an
emergency call manually” (
page 245).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.

ter the emergency call has been initiated.

provided they can speak to an occupant of
the vehicle.The Tele Aid system is available if
it has been activated and is operation-
al. Activation requires a subscription
for monitoring services, connection,
and cellular air time

371 Practical hints
Towing the vehicle
Towing 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. This method is pref-
erable to other types of towing.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 (except vehi-
cles with 4MATIC) only so far as necessary
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 SmartKey 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
(page 85) and the automatic central
locking (
page 106).
Do not tow-start the vehicle.
!Vehicles with 4MATIC:
Do not tow with one axle raised. Doing
so could damage the transfer case,
which is not covered by the Mer-
cedes-Benz Limited Warranty.
All wheels must be on or off the ground.
Observe instructions for towing the ve-
hicle with all wheels on the ground.
!If the vehicle is towed with the front
axle raised (not permissible for vehicles
with 4MATIC), the engine must be shut
off (SmartKey in starter switch
position0 or 1). 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 SmartKey
must be in starter switch position2.
When towing the vehicle with all wheels
on the ground or the front axle raised,
the vehicle may be towed only for dis-
tances up to 30 miles (50 km) and at a
speed not to exceed 30 mph
(50 km/h).

hicle doors lock if the left front wheel
as well as the right rear wheel are turn-
ing at vehicle speeds of approximately
9 mph (15 km/h) or more.

done using the properly installed tow-
ing eye bolt. Never attach tow cable,
tow rope or tow rod to vehicle chassis,
frame or suspension parts.
