Driving and safety systems
Warning!G
The ESP cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
cannot prevent accidents, including those
resulting from excessive speed in turns, fol-
lowing another vehicle too closely, or aqua-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties of a ESP equipped vehicle must never be
exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or
the safety of others.
!
Driving the vehicle with varied size tires
will cause the wheels to rotate at differ-
ent speeds, possibly causing the ESP to
activate. For this reason, all wheels, in-
cluding the spare wheel, must have the
same tire outside diameter.
!
The engine must be shut off when
the parking brake is being tested on
a brake test dynamometer.
the vehicle is being towed with one
axle raised.
Otherwise, the ESP will engage the
brakes and seriously damage the brake
system.
i
The ABS, BAS, and ESP are automati-
cally switched off when the differential
locks are switched on (
page 161).

Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone opens
a door

The alarm will stay on even if the activating
element (a door, for example) is immedi-
ately closed.
The alarm system will also be triggered
when
someone attempts to raise the vehicle
the vehicle is opened with the mechan-
ical key
someone opens a door from the inside
someone opens the tailgate from the
insideArming 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 being armed.
A red lamp in the tow-away alarm switch
begins to blink after arming the alarm
system (
page 28).
i
In case the engine cannot be started
(yet the vehicle’s battery is charged),
the system is not operational. Contact
an authorized Mercedes-Benz Light
Truck Center or call
1-800-FOR-MERCedes (in the USA), or
1-800-387-0100 (in Canada).
i
If the alarm stays on for more than
20 seconds, an emergency call is initi-
ated automatically by the Tele Aid sys-
tem (
page 202) provided Tele Aid
service was subscribed to and properly
activated, and that necessary cellular
service and GPS coverage are avail-
able.

Automatic transmission
Gear selector lever position
Effect
ìPark position
Gear selector lever position
when the vehicle is parked. Place
gear selector lever in positionP
only when vehicle is stopped.
The park position is not intended
to serve as a brake when the
vehicle is parked. Rather, the
driver should always set the
parking brake in addition to
placing the gear selector lever in
positionP to secure the vehicle.
Effect
The SmartKey can only be
removed from the starter switch
with the gear selector lever in
positionP. With the SmartKey
removed, the gear selector lever
is locked in positionP.
If the vehicle’s electrical system
is malfunctioning, the gear
selector lever could remain
locked in positionP
(
page 329).
íReverse gear
Place gear selector lever in
positionR only when vehicle is
stopped.
Effect
ëNeutral
No power is transmitted from the
engine to the drive axle. When
the brakes are released, the
vehicle can be moved freely
(pushed or towed).

!
Coasting the vehicle, or driving for any
other reason with gear selector lever
inN can result in transmission damage
that is not covered by the
Mercedes-Benz Limited Warranty.Warning!G
Getting out of your vehicle with the gear se-
lector lever not fully engaged in positionP is
dangerous. Also, positionP alone is not in-
tended to or capable of preventing your ve-
hicle from moving, possibly hitting people or
objects.
Always set the parking brake in addition to
shifting to positionP (
page 57).
When parked on an incline, turn the front
wheels towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could move the gear selector lever from
positionP, which could result in an accident
and/or serious personal injury.

Loading
Loading instructions
The gross vehicle weight which is the
weight of the vehicle including fuel, tools,
spare wheel, installed accessories, pas-
sengers and luggage / cargo must never
exceed the Gross Vehicle Weight Rating
(GVWR) for your vehicle. In addition, the
load must be distributed in such a way so
that the weight on each axle never exceeds
the Gross Axle Weight Rating (GAWR) for
the front and rear axle. The GVWR and
GAWR for your vehicle are indicated on the
certification label which can be found on
the driver’s door B-pillar (
page 368). The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the vehicle according to the illustra-
tions shown, with the heaviest items being
placed towards the front of the vehicle.
Warning!G
Always fasten items being carried as secure-
ly as possible using cargo tie-down rings and
fastening materials appropriate for the
weight and size of the load.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, always use parti-
tion net when transporting cargo.
Never ride vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in uncon-
sciousness and death.

Emergency calls
An emergency call is initiated
automatically:
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 88) and tow-away alarm
(
page 89)
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. 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
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 Response Center will attempt to deter-
mine more precisely the nature of the acci-
dent 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
Center
i
Location 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
Response Center.
