72 Safety and Security
Occupant safety
CLK cabriolet: Rear side impact air
bags*
1Rear side impact air bag*
The rear side impact air bags*1 are
deployed:

on the impacted side of the vehicle

in side impacts exceeding a preset de-
ployment threshold

independently of the front air bags
The rear side impact air bags*1 are not
deployed in impacts which do not exceed
the system’s deployment threshold.
Occupant Classification System
The O
ccupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.Occupants must sit properly belted in a
position that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
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.
Both driver and the front passenger should
always use the 56 indicator lamp
as an indication of whether or not the front
passenger is properly positioned.
iCLK coupe: The system does not deactivate
the front passenger side impact air bag, the win-
dow curtain air bag and the emergency tension-
ing device.
CLK cabriolet: The system does not deactivate
the head-thorax air bag and the emergency ten-
sioning device.
iIf your seat, including your 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.
