Occupant safety
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 di-
rections at all times.
Both driver and the front passenger should
always use the 75indicator
lamp as an indication of whether or not the
front passenger is properly positioned.
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 your autho-
rized Mercedes-Benz Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Warning!
G
If the 75indicator 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 light
goes out, or check whether objects are
caught under or around the seat.
More information about air bag display mes-
sages (
page 390).
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.
