Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-
egorizes the person in the front-passenger seat.
Depending on that result, the front-passenger
front air bag is either enabled or deactivated.
The system does not deactivate:
the side impact air bag
R
the window curtain air bag
R
the Emergency Tensioning Devices
R
In the following situation, the side impact air bag
and the Emergency Tensioning Device are deac-
tivated:
OCS has not categorized the person on the
R
front-passenger seat as an adult or a person
of corresponding stature and
the seat belt tongue of the seat belt is not
R
inserted into the front-passenger seat belt
buckle
Prerequisites
To be classified correctly, the front passenger
must sit:
with the seat belt fastened correctly
R
in an almost upright position with their back
R
against the seat backrest
with their feet resting on the floor, if possible
R
If the front passenger does not observe these
conditions, OCS may produce a false classifica-
tion, e.g. because the front passenger:
transfers their weight by supporting them-
R
selves on a vehicle armrest
sits in such a way that their weight is raised
R
from the seat cushion
If it is absolutely necessary to install a child
restraint system on the front-passenger seat, be
sure to observe the correct positioning of the
child restraint system. Never place objects
under or behind the child restraint system, e.g.
cushions. The entire base of the child restraint
system must always rest on the seat cushion of
the front-passenger seat. The backrest of the
forward-facing child restraint system must lie as
flat as possible against the backrest of the front-
passenger seat.
The child restraint system must not touch the
roof or be subjected to a load by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint sys-
tem manufacturer's installation instructions.
Occupant Classification System opera-
tion (OCS)
PASSENGER AIR BAG ON indicator lamp
:
PASSENGER AIR BAG OFF indicator lamp
;
The indicator lamps indicate whether the front-
passenger front air bag is activated or deactiva-
ted.
Press the start/stop button once or twice, or
X
turn the SmartKey to position 1 or 2 in the
ignition lock.
The system carries out a self-diagnosis test.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul-
taneously for about six seconds.
The indicator lamps then display the status of
the front-passenger front air bag:
PASSENGER AIRBAG ON lights up: the front-
R
passenger front airbag is enabled. If, in the
case of an accident, all deployment criteria
are met, the front-passenger front air bag is
deployed.
PASSENGER AIRBAG OFF lights up: the front-
R
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
If the status of the front-passenger front air bag
changes whilst the vehicle is in motion, an air
bag display message may appear in the instru-
ment cluster ( page 290). Always observe the
Y
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps when the front-
passenger seat is occupied. Make sure that the
status of the front-passenger front air bag is
correct before and during a journey.
