Occupant safety
The air bags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protec-
ted by the fastened seat belts.
The front passenger front air bag will only
be deployed if:

the system senses that the front
passenger seat is occupied

the 59indicator lamp in
the center console is not lit
(

ment thresholdSide impact air bags, window curtain

1Front side impact air bag
2Window curtain air bag
3Rear side impact air bag*
The side impact air bags and window
curtain air bags are deployed:

on the impacted side of the vehicle

in impacts exceeding a preset deploy-
ment threshold

independently of the front air bags
In addition, the window curtain air bags2
are deployed in certain vehicle rollovers.
Warning!G
The pressure sensors for side impact air bag
control are located in the doors. Do not
modify any components of the doors or door
trim panels including, for example, the addi-
tion of door speakers.
Improper repair work on the doors or the
modification or addition of components to
the doors create a risk of rendering the
side impact air bags inoperative or causing
unintended air bag deployment. Work on the
doors must therefore only be performed by
qualified technicians. Contact an authorized
Mercedes-Benz Light Truck Center.

81 Safety and Security
Occupant safety
The side impact air bags and window cur-
tain air bags are not deployed in impacts
which do not exceed the system’s deploy-
ment threshold.
The front passenger side impact air bag
will not deploy if the OCS senses that the
front passenger seat is empty and the front
passenger seat belt is not fastened (latch
plate is not inserted into the buckle). With
an empty front passenger seat and the
seat belt fastened (latch plate properly in-
serted into buckle) the front passenger
side impact air bag will deploy indepen-
dently of the empty seat.Occupant Classification System
The Occupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a
position that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by lean-
ing on armrests), the OCS may not be able
to properly approximate the occupant’s
weight category.Furthermore, the occupant weight may ap-
pear to increase or decrease due to
objects hanging on the seat, other passen-
gers pushing on the seat, objects lodged
underneath the seat or stuffed between
seat and middle console or between seat
and door or due to objects applying pres-
sure on the back of the seat. Always make
sure that the seat has clearance in all
directions at all times.
Both, driver and the front passenger
should always use the
59indicator lamp as an indi-
cation of whether or not the front passen-
ger is properly positioned.
Warning!G
Only use seat covers which have been test-
ed and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the front side impact air bags or the rear
side impact air bags*. Contact your autho-
rized Mercedes-Benz Light Truck Center for
availability.
iThe system does not deactivate the front
passenger side impact air bag, the window
curtain air bag, and the emergency tensioning
device.
iIf your seat, including your trim cover and
cushion needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Light Truck Center.
Only seat accessories approved by
Mercedes-Benz may be used.

Occupant safety
Warning!G
USE SEAT BELTS PROPERLY

Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this sec-
tion, as that could result in serious inju-
ries in case of an accident.

Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver air bag, pas-
senger front air bag, side impact air
bags, window curtain air bags for side
windows), ETD (seat belt emergency
tensioning device), and front seat knee
bolsters. The system is designed to en-
hance the protection offered to properly
belted occupants in certain frontal (front
air bags and ETD) and side (side impact,
window curtain air bags and ETD) im-
pacts which exceed preset deployment
thresholds and in certain rollovers (win-
dow curtain air bags and ETD).

Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a frontal crash, your body would
move too far forward. That would in-
crease the chance of head and neck in-
juries. The belt would also apply too
much force to the ribs or abdomen,
which could severely injure internal or-
gans such as your liver or spleen.

Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, SmartKeys, etc., as
these might cause injuries.

Position the lap belt as low as possible
on your hips and not across the abdo-
men. If the belt is positioned across your
abdomen, it could cause serious injuries
in a crash.

Never use a seat belt for more than one
p e r s o n a t t i m e . D o n o t f a s t e n a s e a t b e l t
around a person and another person or
other objects.

Belts should not be worn twisted. In a
crash, you would not have the full width
of the belt to distribute impact forces.
The twisted belt against your body could
cause injuries.

Pregnant women should also always use
a lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.

Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.

When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.

Warning!G
After installing top tether straps, make sure
that the seat backrests are in an upright po-
sition and are properly locked. Check for
secure locking by pushing and pulling on the
seat backrests. If a seat backrest is not
properly locked, the seat backrest could
fold. The child seat would no longer be prop-
erly supported or positioned to provide its
intended benefit.
Warning!G
Activate the override switch when children
are riding in the back seats of the vehicle.
The children could otherwise injure them-
selves, e.g. by becoming trapped in the win-
dow opening.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised
access to a vehicle could result in an
accident and/or serious personal injury.
