WARNING
If the red 001DSRS warning lamp in the
instrument cluster and the 0018001A
indicator lamp light up simultaneously, the
OCS is malfunctioning. The front passenger
front air bag will be deactivated in this case.
Have the system checked by qualified
technicians as soon as possible.C ontactan
authorized Mercedes-Ben zCenter.
Only have the seat repaired or replaced at an
authorized Mercedes-Benz Center.
In order to ensure proper operation of the air
bag system and OCS:
R Sit with the seat belt properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
R When seated, a passenger should not
position him/herself in such a way as to
cause the passenger's weight to be lifted
from the seat cushion as this may result in
the OCS being unable to correctly
approximate the passenger's weight
category.
R Read and observe all warnings in this
chapter. If the SmartKey is removed from the ignition
lock or is in position 0,PASSENGER AIR BAG
OFF indicator lamp 0002does not light up.
The Occupant Classification System (OCS)
categorizes the occupant on the front-
passenge rseat using a weight sensor.
The front-passenger fron tair bag is
deactivated automatically for certain weight
categories. If the PASSENGER AIR BAG OFF indicator
lamp is lit, the passenger air bag is disabled.
The PASSENGER AI
RBAG OFF indicator lamp
shows you the current status.
The system does not deactivate:
R the side impact ai rbag
R the pelvis air bag
R the window curtain air bag (Coupe)
R the front-passenger head bag (Cabriolet)
R the Emergency Tensioning Devices
To be classified correctly, the fron tpassenger
must sit:
R with the seat belt fastened correctly
R in a positio nthat 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.
For safety reasons, Mercedes-Benz
recommends 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
positioned correctly. Observe also the air bag
display messages that can be displayed in the
instrument cluster (Y page 256).
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy. 52
Occupant safetySafety 

The OCS may have detected that the seat:
R is empty or occupied by the weight of a
typical child up to twelve months old,
seated in a child restraint system.
R is occupied by a small individual, such as a
young teenager or a small adult.
R is occupied by a child in a child restraint
system whose weight is greater than that
of a typical twelve month old child.
These are examples of when the OCS
deactivates the front-passenger fronta ir bag.
Deactivation takes place although the
collision fulfills the criteria for deploying the
driver's air bag.
For further information, see "Air bag display
messages" (Y page 256).
System self-test G
WARNING
If the 0018001Aindicator lamp does not
illuminate, the system is not functioning. You
must contact an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat. G
WARNING
Objects betwee nthe seat surface and the
child restraint system could affect the
function of the OCS. This could result in the
front-passenger front air bag not functioning
as intended during an accident. This poses an
increased risk of injury or even fatal injury.
Do not place any objectsb etween the seat
surface and the child restraint system. Make
sure that the bottom and back of the child
restraint system make full contact with the
front-passenger seat cushion and backrest.
Always comply with the child restraint system
manufacturer's installation instructions. The PASSENGER AIR BAG OFF indicator lamp
lights up:
R
if you turn the SmartKey in the ignition lock
to position 1or 2
R if you press the KEYLESS-GO Start/Stop
button once or twice on vehicles with
KEYLESS-GO
R if an adult is seated properly on the front-
passenger seat and the OCS classifies the
occupant as an adult
The PASSENGER AIR BAG OFF indicator
lamp goes out again after approximately six
seconds.
If the seat is not occupied and the OCS
detects that the front-passenger seat is
empty, the PASSENGER AIR BAG OFF
indicator lamp will continue to light up. The
PASSENGER AIR BAG OFF indicator lamp
will not go out.
For more information about the OCS, see

System" (Y page 54). Occupant safety
