58 Getting started
Driving
Driving off
Depress the brake pedal.
The gear selector lever can now be
used.
Shift automatic transmission toD orR
(
page 199).
Release the brake pedal.
Carefully depress the accelerator
pedal.After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter
(gasoline engine) or the oxidation catalyst
(diesel engine) to reach its operating tem-
perature earlier.
iWait for the gear selection process to
complete before setting the vehicle in motion.
iShifting from gear positionP to position R,
N, orD is only possible with the brake pedal
depressed. Without the brake pedal depressed,
the gear selector lever can be moved, but the
parking pawl remains engaged, not allowing
shifting to occur.
!If you hear a warning signal and the
message
Release parking brake appears in
the multifunction display when driving off, you
have forgotten to release the parking brake.
Release the parking brake (
page 57).
iOnce the vehicle is in motion, the automatic
central locking system engages and the locking
knobs drop down.
The automatic door lock feature can be
deactivated (
page 189).
You can open a locked door from the inside.
Open door only when conditions are safe to
do so.
Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.
Warning!G
It is dangerous to shift the gear selector
lever out ofP orN if the engine speed is
higher than idle speed. If your foot is not
firmly on the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.

68 Getting started
Parking and locking
Releasing seat belts
Press the seat belt release button
(
page 52).
Allow the retractor to completely re-
wind the seat belt by guiding the latch
plate.
Locking
Exit the vehicle and close all doors and
the tailgate.
Locking with the SmartKey
Press button‹on the SmartKey
(
page 38).
With the tailgate and all doors closed,
the turn signal lamps flash three times.
The locking knobs on the doors move
down. The anti-theft alarm system is
armed.
For more information, see “Locking and
unlocking” (
page 112).
!Make sure the seat belt retracts fully so that
the seat belt and/or latch plate cannot get
caught or pinched in the door or in the seat
mechanism. This can damage the seat belt and
impair the effectiveness of the seat belt, and/or
cause damage to the door and/or door trim pan-
el. Such damage is not covered by the
Mercedes-Benz Limited Warranty.
Damaged seat belts must be replaced.
Contact an authorized Mercedes-Benz Light
Truck Center.
Warning!G
To prevent possible personal injury, always
keep hands and fingers away from the door
openings when closing the doors.
Be especially careful when small children
are around.
Before closing doors, make sure there is no
possibility of someone getting caught in a
door during closing.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take the
SmartKey with KEYLESS-GO* with you, and
lock your vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. Unsupervised use of
vehicle equipment may cause an accident
and/or serious personal injury.
iIf you hear a warning signal, you have
forgotten to switch off the exterior lamps before
opening the driver’s door.
In addition the message
Switch off lights
appears in the multifunction display.
Switch off the exterior lamps.

89 Safety and Security
Occupant safety
Warning!G
If the 59indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the front passenger
seat, have the front passenger reposition
himself or herself in the seat until the
59 indicator lamp goes out, or
check whether objects are caught under or
around the seat.
More information about air bag display
messages (
page 445).
In the event of a collision, the air bag control
unit will not allow front passenger front air
bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child re-
straint or if the front passenger seat is
sensed as being empty.
When the OCS senses that the front passen-
ger seat occupant is classified as being up
to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 59indicator
lamp will illuminate when the engine is
started and remain illuminated, indicating
that the front passenger front air bag is de-
activated.
When the OCS senses that the front passen-
ger seat is classified as being empty, the
59indicator lamp will illumi-
nate when the engine is started and remain
illuminated, indicating that the front passen-
ger front air bag is deactivated.When the OCS senses that the front passen-
ger seat occupant is classified as being
heavier than the weight of a typical
12-month-old child seated in a standard
child restraint or as being a small individual
(such as a young teenager or a small adult),
the 59 indicator lamp will illu-
minate for approximately 6 seconds when
the engine is started and then, depending on
occupant weight sensor readings from the
seat, remain illuminated or go out. With the
59 indicator lamp illuminated,
the front passenger front air bag is deacti-
vated. With the 59indicator
lamp out, the front passenger front air bag is
activated.
When the OCS senses that the front passen-
ger seat occupant is classified as an adult or
someone larger than a small individual, the
59 indicator lamp will illumi-
nate for approximately 6 seconds when the
engine is started and then go out, indicating
that the front passenger front air bag is acti-
vated.


106 Safety and Security
Driving safety systems
4-ETS
The 4-Electronic Traction System (4-ETS)
improves the vehicle’s ability to utilize
available traction, especially under slip-
pery road conditions. The brakes are ap-
plied to the spinning wheel and power is
transferred to the wheel(s) with traction.
The ESP
® warning lampvin the instru-
ment cluster starts to flash at any vehicle
speed, as soon as a tire loses traction and
the wheel begins to spin.
For more information, see the “Practical
hints” section (
page 420) and
(
page 433).
Warning!G
When you see the ESP® warning lampv
flashing in the instrument cluster, then pro-
ceed as follows:

While driving off, apply as little throttle
as possible.

While driving, ease up on the accelera-
tor.

Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The 4-ETS cannot prevent accidents resul-
ting from excessive speed.
!Operational or performance test must only
be conducted on a two-axle dynamometer. If
such tests are necessary, contact an authorized
Mercedes-Benz Light Truck Center. You could
otherwise seriously damage the brake system or
the transfer case which is not covered by the
Mercedes-Benz Limited Warranty.
!Because the ESP® operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO* start/stop button in
position0or1) when testing the brakes on a
brake test dynamometer and such testing should
be no longer than 10 seconds.
Active braking action through ESP
® may other-
wise seriously damage the brake system which is
not covered by the Mercedes-Benz Limited
Warranty.
iIf the yellow ESP® warning lampv
comes on while driving, the 4-ETS is being
switched off temporarily to prevent overheating
of the drive wheel brakes. In addition, the
message
ABS, ESP unavailable See
Operator’s Manual
appears in the
multifunction display.
