Starting the engineWarning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as garage) which are not properly ven-
tilated. If you think that exhaust gas fumes
are entering the vehicle while driving, have
the cause determined and corrected imme-
diately. If you must drive under these condi-
tions, drive only with at least one window
fully open.

rious personal injury.
Warning!

It is dangerous to shift the gear selector le-
ver out ofP or N if the engine speed is high-
er than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could accel-
erate 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.
!In order to avoid damaging the trans-
mission,

wait for the gear selection process
to complete before setting the vehi-
cle in motion.

Driving
After a cold start, the automatic transmis-
sion shifts at a higher revolution. This al-
lows the catalytic converter to reach its
operating temperature earlier.
For more information, see “Driving instruc-
tions” (
page 216).
For information on off-road driving, see
“Off-road driving” (
page 223).

!Do not run cold engine at high engine
speeds. Running a a cold engine at high
engine speeds may shorten the service
life of the engine.iYou can open the doors from inside at
any time. Open doors only when the
conditions are safe to do so.
You can deactivate the automatic
locking using the control system
(page 141).
!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
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.

ing lamp; (USA only) or3
(Canada only) in the instrument cluster
will be illuminated.
Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle.
Warning!
G
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.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:

Keep right foot on brake pedal.


Pull the parking brake lever up as many
notches as possible.


Move the gear selector lever to
positionP.


Slowly release brake pedal.


When parked on an incline, turn front
wheels towards the road curb.

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 and/or
move the gear 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 gear se-
lector lever not fully engaged in positionP is
dangerous. 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 positionP.
On slopes, turn the front wheels to-
wards the road curb.

62 Safety and SecurityIn this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.Occupant safety
The restraint systems are

Seat belts


Emergency tensioning device


Airbags


Child seats


Child seat recognition


Lower anchors and tethers for children
(LATCH)
As independent systems, their protective
effects work in conjunction with each oth-
er.The 1indicator lamp in the instrument
cluster (
page 25) comes on:


for about four seconds when you turn
the SmartKey in the starter switch to
position1.


for about four seconds when you start
the engine by turning the SmartKey.
The 1indicator lamp goes out shortly
after you start the engine. This shows that
the restraint systems are operational.
iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 72).
iThe 1indicator lamp remains lit if
the SmartKey is turned to position2
and left there. The indicator lamp will
go out when you start the engine.

63 Safety and Security
Occupant safety
A malfunction in the system has been de-
tected if the 1 indicator lamp:

fails to extinguish after approximately
four seconds.


does not come on at all.


comes on after the engine was started
or while driving.
For safety reasons, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Light Truck Center imme-
diately to have the system checked.
For more information, see “Practical hints”
(
page 294).
Airbags
Warning!
G
In the event that the 1indicator lamp
comes on during driving or does not come
on at all, the SRS self-check has detected a
malfunction. For your safety, we strongly
recommend 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.
In addition, through improper work there is
a risk of rendering the SRS inoperative or
causing unintended airbag deployment.
Work on the SRS must therefore only be per-
formed by qualified technicians. Contact 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 airbags temporarily re-
leases a small amount of dust from the air-
bags. This dust, however, is neither injurious
to your health, nor does it indicate a fire in
the vehicle. The dust might cause some tem-
porary breathing difficulty for people with
asthma 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.
