R independently of the ETDs
The passenger head-thorax air bag : will
only deploy if the OCS senses that the
passenger seat is occupied and the impact
exceeds a preset deployment threshold.
Head-thorax air bags : are not deployed in
side impacts which do not exceed the
system’s deployment threshold. G
Warning!
Only use seat covers which have been tested
and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the head-thorax air bags. Contact an
authorized Mercedes-Benz Center for
availability. Occupant Classification System
The Occupant Classification System (OCS)
activates or deactivates the passenger front
air bag and passenger-side knee bag
automatically.
The respective status is based
on the classified occupant weight category
determined by weight sensor readings from
the passenger seat.
The system does not deactivate the
passenger head-thorax air bag and the
Emergency Tensioning Devices (ETDs).
To be classified correctly, the passenger must
sit
R with the seat belt properly fastened
R in a position that is as upright as possible
with the back against the seat backrest
R with the feet on the floor
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by leaning
on armrests), the OCS may not be able to
properly approximate the occupant’s weight
category.
If your seat, including the trim cover and
cushion, needs to be serviced in any way, take the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Both the driver and the passenger should
always use the
04 indicator
lamp as an indication of whether or not the
passenger is properly positioned. G
Warning!
If the 04 indicator lamp
illuminates when an adult or someone larger
than a small individual is in the passenger
seat, have the passenger reposition himself
or herself in the seat until the
04 indicator lamp goes out.
In the event of a collision, the air bag control
unit will not allow passenger front air bag
deployment when the OCS has classified the
passenger seat occupant as weighting as
much as or less than a typical 12-month-old
child in a standard child restraint or if the
passenger seat is classified as being empty.
When

the OCS senses that the 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
04 indicator lamp will illuminate
when the engine is started and remain
illuminated, indicating that the passenger
front air bag is deactivated.
When the OCS senses that the passenger seat
is classified as being empty, the
04 indicator lamp will illuminate
when the engine is started and remain
illuminated, indicating that the passenger
front air bag is deactivated.
When the OCS senses that the passenger seat
occupant is classified as being heavier than
the weight of a typical 12-month-old child
seated in a standard child restraint or as being
a small individual (such as a young teenager
or a small adult), the 04
indicator lamp will illuminate for
approximately 6 seconds when the engine is
started and then, depending on occupant Occupant safety
