76 Safety and Security
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, based on OCS sensor read-
ings, senses that the front passenger
seat is occupied

the 59indicator lamp in
the center console is not lit
(
page 81)

the impact exceeds a preset deploy-
ment thresholdSide impact air bags, window curtain
air bags
1Front side impact air bag
2Window curtain air bag
3Rear side impact air bag
(second-row seats, USA only)
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
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 creates 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.

77 Safety and Security
Occupant safety
In addition, the window curtain air bags2
are deployed in certain vehicle rollovers.
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.
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.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
appear 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 the seat has clearance in all direc-
tions at all times.
Both, driver and the front passenger
should always use the 59 in-
dicator lamp as an indication of whether or
not the front passenger is properly posi-
tioned.
iThe system does not deactivate the front
passenger side impact air bag, the window cur-
tain air bag, and the emergency tensioning de-
vice.
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.
