cal innovations. If you are already familiar
with the basic functions of your vehicle,
this section will be of particular interest to
you.Operation
Here you will find all the information you
need for the proper operation of your vehi-
cle.Practical hints
This section provides fast assistance for

51 Getting started
Parking and locking
Switching off headlamps
Turn the exterior lamp switch to
M
(
page 46).
More information can be found in the
“Controls in detail” section (
page 100).
Turning off engine
Place the selector lever in positionP.
Turn key in the starter switch to
position0 and remove it.
The immobilizer is activated.
Press the seat belt release button
(page 41).
Allow the retractor to completely re-
wind the seat belt by guiding the latch
plate.
Warning!
G
When leaving the vehicle, always remove the
key from the starter switch, and lock the ve-
hicle. Do not leave children unattended in
the vehicle, or with access to an unlocked
vehicle. Children could release the parking
brake and/or move the selector lever from
positionP, either of which could result in an
accident and/or serious personal injury.Warning!
G
Getting out of your vehicle with the selector
lever not fully engaged in positionP is dan-
gerous. Also, when parked on an incline,
positionP alone may not prevent your vehi-
cle from moving, possibly hitting people or
objects.
Always set the parking brake in addition to
shifting to positionP.
When parked on an incline, turn front wheels
towards the road curb.
iAlways set the parking brake in addi-
tion to shifting to position P.
On slopes, turn the front wheels to-
wards the curb.
iThe key can only be pulled out when:
it has been turned to position0 in
the starter switch
the gear selector lever for the auto-
matic transmission is in positionP
you are not braking with the service
brake
!With the key removed and the driver’s
door open, a warning sounds if the ve-
hicles exterior lamps are not switched
off.
55 Safety and Security
Occupant safety
Airbags
Warning!
G
In the event that the SRS malfunction indica-
tor lamp lights up during driving or does not
come on at all, the SRS may not be opera-
tional. For your safety, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Light Truck Center immedi-
ately to have the system checked; otherwise
the SRS may not be activated when needed
in an accident, which could result in serious
or fatal injury, or it might deploy unexpect-
edly and unnecessarily which could also re-
sult in injury.
Improper work on the restraint systems can
lead to unintentional deployment or opera-
tional failure.
All work on these systems should therefore
only be carried out by an authorized
Mercedes-Benz Light Truck Center.
Warning!
G
Airbags are designed to reduce the potential
of injury in certain frontal (front airbags) im-
pacts, which may cause significant injuries.
However, no system available today can to-
tally eliminate injuries and fatalities.
The activation of the SRS temporarily releas-
es a small amount of dust from the airbags.
This dust, however, is neither injurious to
your health, nor does it indicate a fire in the
vehicle. The dust might cause some tempo-
rary breathing difficulty for people with asth-
ma or other breathing trouble. To avoid this,
you may wish to get out of the vehicle as
soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the airbag inflates, then get
fresh air by opening a window or door.
Warning!
G
The service life of the front passenger airbag
extends to the date indicated on the label lo-
cated on the driver side B pillar. To provide
continued reliability after that date, they
should be inspected by an authorized Mer-
cedes-Benz Light Truck Center at that time
and replaced when necessary.

someone attempts to raise the vehicle
opening the vehicle with the mechani-
cal keyArming the alarm system
The alarm system is armed after locking
the vehicle with the SmartKey. The turn
signal lamps blink three times to indicate
that the alarm system is activated. A red
lamp in the tow-away alarm switch will
blink after approximately 10 seconds
when the alarm system is completely
armed (
page 27).
iIf the alarm stays on for more than
20 seconds, an emergency call is initi-
ated automatically by the Tele Aid sys-
tem (

three times, one of the following ele-
ments may not be properly closed:
a door

the hood
Close the respective element and lock
the vehicle again.
iThe tow-away protection alarm is trig-
gered, for example, if the vehicle is lift-
ed on one side.

A driver’s attention to the road and traffic
conditions must always be his /her primary
focus when driving.
For your safety and the safety of others, se-
lecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 13.5 m) every second.

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 79) and tow-away alarm
(
page 80)
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 –

appears in the multifunc-
tion display. When the connection is estab-
lished, the message
EMERGENCY CALL –
CALL CONNECTED
appears in the multifunction display. All information rele-
vant to the emergency, such as the loca-
tion of the vehicle (determined by the GPS
satellite location system), vehicle model,
identification number and color are gener-
ated.
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 mutes and the message
TELE AID – EMERGENCY CALL ACTIVE
ap-
pears in the multifunction display. The Re-
sponse Center will attempt to determine
more precisely the nature of the accident
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
the relevant cellular phone network
and GPS signals are available and pass
the information on to the response cen-
teriLocation of the vehicle on a map is only
possible if the vehicle is able to receive
signals from the GPS satellite network
and pass the information on to the re-
sponse center.
