Occupant Classification System
The Occupant Classification System (OCS) is
standard equipment in USA.
The OCS automatically turns the front
passenger front air bag on or off based on the
classified occupant weight category
determined by weight sensor readings from
the front passenger seat.
The system does not deactivate the front
passenger side impact air bag, the window
curtain air bag and the Emergency Tensioning
Devices (ETDs).
Occupants must sit with the seat belt
properly fastened 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 leaning 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 the
following: objects hanging on the seat, lodged
underneath the seat, stuffed between 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. Always make sure the seat has
clearance in all directions at all times.
i
If your seat, including the 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.
Both the driver and the front passenger
should always use the
59
indicator lamp as an indication of whether or
not the front passenger is properly
positioned.
G
Warning!
If the
59
indicator lamp
illuminates 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
59
indicator lamp
goes out, or check whether objects are
caught under or around the seat.
In the event of a collision, the air bag control
unit will not allow front passenger front air
bag deployment when the OCS has
classified the front passenger seat
occupant as weighting as much as or less
