48 Safety and SecurityOccupant safetyOccupant 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 po-
sition 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 the fol-
lowing: objects hanging on the seat,
lodged underneath the seat, stuffed be-
tween the seat and middle console or the
seat and door, other passengers pushing
on the seat or objects applying pressure to
the back of the seat.
Both driver and the front passenger should
always use the 59indicator
lamp as an indication of whether or not the
front passenger is properly positioned.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 an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Warning!
G
If the 59indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the
59indicator lamp goes out, or
check whether objects are caught under or
around the seat.
More information about air bag display mes-
sages (
page 622).
In the event of a collision, the air bag control
unit will not allow front passenger front air
bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child re-
straint or if the front passenger seat is
sensed as being empty.
