Example: Coupe
Headbags
:deploy in the side window area.
They are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
R if the system determines that the vehicle
occupants are offered additional
protection to that provided by the seat belt
R independently of the use of the seat belt
R independently of the ETDs
R on the driver's side and passenger side, in
the event of a vehicle rollover and if the
system determines that air bag deployment
can offer the vehicle occupants additional
protection to that provided by the seat belt
R independently of the front air bags
Head bags :will not deploy in side impacts
which do not exceed the system's preset
deployment thresholds for lateral
acceleration/deceleration. You will then be
protected by the fastened seat belt.
If the OCS has classified the front-passenger
seat as unoccupied and the front-passenger
seat belt is not fastened, the head bag on the
passenger side will not deploy. The head bag
on the front-passenger side will deploy if the
front-passenger seat belt is fastened,
regardless of whether the front-passenger
seat is occupied or not. Occupant Classification System
(OCS)
How the Occupant Classification
System works The Occupant Classification System (OCS)
categorizes the occupant on the front-
passenger seat using a weight sensor. The
front-passenger front air bag and the front-
passenger knee bag are deactivated
automatically for certain weight categories.
The
45 indicator lamp shows you the
current status. When the 45indicator
lamp is illuminated, the front-passenger front
air bag and the front-passenger knee bag are
deactivated.
The system does not deactivate:
R the front-passenger side impact air bag
R the front-passenger head bag
R the Emergency Tensioning Devices
To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in a position that is as upright as possible
with their back against the seat backrest
R with their feet on the floor
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.
To establish whether the front passenger is
being properly detected, both the driver and
the front passenger should pay attention to
the 45 indicator lamp.
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 that have been approved by
Mercedes-Benz. 42
