Indicator Lamp - Mercedes-Benz GL Operator's Manual

Occupant Classification System
(OCS)
How the occupant classification
system works
The OCS is standard equipment in the USA.
The OCS categorizes the occupant on the
front-passenger seat by means of a weight
sensor. The front-passenger front air bag is
deactivated automatically for certain weight
categories. The 42 indicator
lamp shows you the current status. If the
42 indicator lamp is illuminated,
the front-passenger front air bag is
deactivated.
The system does not disable:
the side impact air bag
R
the window curtain air bag
R
the Emergency Tensioning Devices/belt
R
buckle tensioners
To be classified correctly, the front passenger
must sit:
with the seat belt fastened correctly
R
in a position that is as upright as possible
R
with their back against the seat backrest
with their feet on the floor
R
If the front-passenger's weight is transferred
to another object in the vehicle (e.g. by
leaning on armrests), OCS may not be able to
approximate the occupant's weight category.
In addition, the occupant weight may appear
to increase or decrease due to the following:
objects hanging on the seat
R
objects lodged underneath the seat
R
objects lodged between the seat and the
R
center console
objects lodged between the seat and the
R
door
other passengers exerting weight on the
R
seat
objects applying pressure to the back of
R
the seat
Make sure that the seat always has clearance
in all directions.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repair work carried out at an
authorized Mercedes-Benz Center.
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories which have been approved by
Mercedes-Benz.
Both the driver and the passenger should
always use the 42 indicator
lamp as an indication of whether or not the
passenger is properly positioned.

WARNING
If the 42 indicator lamp
illuminates when an adult or someone larger
than a small individual is in the front
passenger seat, have the front passenger
reposition himself or herself in the seat until
the 42 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 weighing as
much as or less than a typical 12-month-old
child in a standard child restraint or if the front
passenger seat is classified as being empty.
When the OCS senses that the front
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 42 indicator lamp
will illuminate when the engine is started and
remain illuminated. This indicates that the
front passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat is classified as being empty,
the 42 indicator lamp will
illuminate when the engine is started and
remain illuminated. This indicates that the
front passenger front air bag is deactivated.
