53 Getting started
Driving
Proper use of seat belts

Do not twist the seat belt when fasten-
ing.

Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck). Never pass the
shoulder portion of the seat belt under
your arm. For this purpose, you can
adjust the height of the seat belt guide
(
page 52).

Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.

Place the seat backrest on adjustable
seat backrests in a nearly upright
position.

Never use a seat belt for more than one
person at a time.

Do not fasten a seat belt around a
person and another object at the same
time. When using a seat belt to secure
infant restraints, toddler restraints or
children in booster seats, always follow
the child seat manufacturer’s instruc-
tions.

Check your seat belt periodically
during travel to make sure that it is
properly positioned.

Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
Warning!G
Do not pass seat belts over sharp edges.
They could tear.
Do not allow the seat belt to get caught in
the door or in the seat adjustment mecha-
nism. This could damage the seat belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the seat belts.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Damaged seat belts or seat belts that were
highly stressed in an accident must be
replaced. Contact an authorized
Mercedes-Benz Light Truck Center.

transmission” (
page 162).Starting
Make sure the gear selector lever is set

Do not depress the accelerator.
Turn the SmartKey in the starter switch
to position3 (
page 39) and release it
again immediately. The engine starts
automatically.
For information on turning off the engine,
see “Turning off engine” (
page 64).
Starting difficulties
If the SmartKey is left in starter switch
position0 for an extended period of time,
it can no longer be turned in the switch. In
this case, the steering is locked.
To unlock, remove the SmartKey from
the starter switch and reinsert.
If the engine does not start as described,
carry out the following steps:
Turn the SmartKey in the starter switch
to position0 and repeat the starting
procedure.
Warning!G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas
(such as garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open.

55 Getting started
Driving
Remember that extended starting
attempts can drain the battery.
Get a jump start (page 399).
If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.
Contact an authorized Mercedes-Benz
Light Truck Center or call Roadside
Assistance.

positionD or reverse gearR.
Release the brake pedal.
Carefully depress the accelerator.
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 release the parking brake, which
could result in an accident and/or serious
personal injury.
!In order to avoid damage to the transmis-
sion:

Wait for the gear selection process to com-
plete before setting the vehicle in motion.

Place the gear selector lever in park
positionP or reverse gearR only when the
vehicle is stopped.
!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 55).

56 Getting started
Driving
After a cold start, the transmission shifts at
a higher engine revolution. This allows the
catalytic converter to reach its operating
temperature earlier.
For more information, see “Driving instruc-
tions” (
page 245).
For information on off-road driving, see
“Off-road driving” (
page 253).

2Low beam headlamps on
Turn the exterior lamp switch to
positionB.
The low beam headlamp indicator
lampB in the instrument cluster
comes on (
page 26).
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 deacti-
vated (
page 155).
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 or N 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.
!Do not run cold engine at high engine speed.
Running a cold engine at high engine speed may
shorten the service life of the engine.
!Simultaneously depressing the accelerator
pedal and applying the brakes reduces engine
performance and causes premature brake and
drivetrain wear.

!Do not operate the windshield wipers when
the windshield is dry. Dust that accumulates on
a windshield might scratch the glass and/or
damage the wiper blades when wiping occurs on
a dry windshield. If it is necessary to operate the
windshield wipers in dry weather conditions,
always operate the windshield wipers with
windshield washer fluid (
page 59).
!If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off
immediately.

For safety reasons, stop the vehicle in a safe
location, turn off the engine and remove the
SmartKey from the starter switch before
attempting to remove any blockage.

Remove blockage.

Turn the windshield wipers on again.
If the windshield wipers fail to function at all with

wet weather conditions or in the presence
of precipitation.
When you select intermittent wiping, the
rain sensor is activated. The rain sensor

After the initial wipe, pauses between
wipes are automatically controlled by
the rain sensor.Single wipe
Press the combination switch briefly in
direction of arrow1 to the resistance
point.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid
Push the combination switch in direc-
tion of arrow1 past the resistance
point.
The windshield wipers operate with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield/rear window
washer system and headlamp cleaning
system” (
page 275).
!Do not leave windshield wipers in intermit-
tent setting when the vehicle is taken to an auto-
matic car wash or during windshield cleaning.
Windshield wipers will operate in the presence of
water sprayed on the windshield, and windshield
wipers may be damaged as a result.
iIntermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or out
of the vehicle from being sprayed.
Intermittent wiping will be continued when all
doors are closed and

the gear selector lever is in drive positionD
or reverse gearR
or

the wiper setting is changed using the
combination switchiTo prevent smears on the windshield, or
noisy/chattering wiper blades, wipe with wind-
shield washer fluid every now and then even
when it is raining.
