WARNING
If the red 0075SRS warning lamp in the
instrument cluster and the 0073PASSENGER
AIR BAG OFF indicator lamp light up
simultaneously, the OCS is malfunctioning.
The front-passenger front air bag and the
front-passenger knee bag will be deactivated
in this case. Have the system checked as soon
as possible by qualified technicians. Consult
an authorized Mercedes-Benz Center.
Only have the seat repaired at an authorized
Mercedes-Benz Center.
In order to ensure correct operation of the air
bag system and OCS:
R sit with the seat belt fastened correctly and
in a position that is as upright as possible
with your back against the backrest.
R while seated, an occupant should not
position themselves in such a way as to
cause their weight to be lifted from the seat
cushion as this may result in OCS being
unable to correctly assess the occupant's
weight category.
R read and observe all warnings in this
section. 0043
PASSENGER AIR BAG OFF indicator lamp
0044 PASSENGER AIR BAG ON indicator lamp
If the SmartKey is removed from the ignition
lock or is in position 0, PASSENGER AIR BAG
OFF indicator lamp 0043does not light up.
PASSENGER AIR BAG ON indicator lamp 0044
has no function. It lights up briefly when the
ignition is switched on and then goes out
again. Occupant Classification System (OCS)
categories 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.
PASSENGER AIR BAG OFF indicator lamp
0043
shows you the current status. If PASSENGER
AIR BAG OFF indicator lamp 0043lights up, the
front-passenger front air bag and the front-
passenger knee bag are deactivated.
The system does not deactivate:
R the 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
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
necessary repair work carried out at a
qualified specialist workshop.
Mercedes-Benz recommends that you only
use seat accessories which have been
approved by Mercedes-Benz.
Both the driver and the front passenger
should always observe PASSENGER AIR BAG
OFF indicator lamp 0043as an indication of
whether or not the front passenger is
positioned correctly. Observe also the air bag
display messages that can be displayed in the
instrument cluster (Y page 220).
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy. Occupant safety
