Front air bags
1Driver air bag
2Front passenger front air bag
Driver and front passenger front air bags
are deployed:
in the event of certain frontal impacts
if impact exceeds a preset deployment
threshold
independently of the side impact air
bagsThe 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 passenger front air bag will only be
deployed if:
the system, based on OCS weight sen-
sor readings, senses that the front
passenger seat is occupied

the center console is not lit

the impact exceeds a preset deploy-
ment thresholdSide impact air bags
1Front side impact air bag
2Rear side impact air bag
The side impact air bags are deployed:
in impacts exceeding a preset deploy-
ment threshold
on the impacted side of the vehicle
independently of the front air bags
The front passenger side impact air bag1
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
i
The front air bags in this vehicle have been
designed to inflate in two stages. This allows the
air bag to have different rates of inflation that are
based on the rate of relevant vehicle decelera-
tion as assessed by the air bag control unit
On the front passenger-side, the front air bag de-
ployment is additionally influenced by the pas-
senger’s weight category as identified by the
Occupant Classification System (OCS)
(page 50).
The lighter the front passenger-side occupant,
the higher the vehicle deceleration rate required
for the second stage inflation of the air bag.

50 Safety and SecurityOccupant safetyseat belt fastened (latch plate properly in-
serted into buckle) the front passenger
side impact air bag will deploy regardless
of the empty seat.
The side impact air bags are not deployed
in impacts which do not exceed the sys-
tem’s deployment threshold.
Window curtain air bags
1Window curtain air bag
The side window curtain air bags are de-
ployed:
in impacts exceeding a preset deploy-
ment threshold
on the impacted side of the vehicle
independently of the front air bags
in certain vehicle rollovers
The side window curtain air bags are not
deployed in impacts which do not exceed
the system’s deployment threshold.
The window curtain air bags fill up the area
indicated by the arrows.
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
nearly upright position with their back
against the seat backrest and feet on the floor to be correctly classified. If the occu-
pant’s weight is transferred to another
object in the vehicle (e.g. by leaning 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.i
The system does not deactivate the front
passenger side impact air bag, the window cur-
tain air bag and the emergency tensioning de-
vice.
i
If your seat, including your trim cover and
cushion needs to be serviced in any way, take
the vehicle to your authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.
