Occupant Classification System - Mercedes-Benz C-Class Coupe Operator's Manual

Window curtain air bags : are deployed:
on the side on which an impact occurs
R
at the start of an accident with a high rate of
R
lateral vehicle deceleration or acceleration,
e.g. in a side impact
regardless of whether the front-passenger
R
seat is occupied
independently of the use of the seat belt
R
independently of the front air bags
R
Window curtain air bags : will not deploy in
the event of impacts which do not exceed the
system's preset deployment thresholds for
vehicle acceleration/deceleration. You will
then be protected by the fastened seat belt.

Occupant Classification System

(OCS)
How the Occupant Classification Sys-
tem works
The Occupant Classification System (OCS)
categorizes the occupant on the front-
passenger seat using a weight sensor. The
front-passenger front air bag is deactivated
automatically for certain weight categories.
The PASSENGER AIR BAG OFF indicator lamp
shows you the current status. If the
PASSENGER AIR BAG OFF indicator lamp is
lit, the passenger air bag is disabled.
The system does not deactivate:
the side impact air bag
R
the pelvis air bag
R
Occupant safety
the window curtain air bag
R
the Emergency Tensioning Devices
R
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
The OCS weight sensor reading is affected if
the occupant's weight is transferred, e.g. by
leaning on the armrest.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the nec-
essary repair work carried out at a qualified
specialist workshop.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat accessories
that have been approved by Mercedes-Benz.
Both the driver and the front passenger
should always observe the PASSENGER AIR
BAG OFF indicator lamp as an indication of
whether or not the front passenger is posi-
tioned correctly. Observe also the air bag dis-
play messages that can be displayed in the
instrument cluster (

G WARNING
If the 45 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 her-
self in the seat until the 45 indicator
lamp goes out.
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 45 indicator lamp will
illuminate when the engine is started and
