The front passenger side impact air bag will
not deploy if the OCS senses that the front
passenger seat is empty and the front
passenger seat belt is not fastened (latch
plate is not inserted into the buckle). With an
empty front passenger seat and the seat belt
fastened (latch plate properly inserted into
buckle) the front passenger side impact air
bag will deploy independently of the empty
seat.
The side impact air bags are not deployed in
side impacts which do not exceed the
system’s deployment threshold.
The side air bags will not deploy in the event
of a rollover unless the vehicle’s rate of lateral
deceleration or acceleration exceeds the
preset deployment threshold for the side air
bags.
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 side impact air bags.
Contact an authorized Mercedes-Benz
Center for availability.

The Occupant Classification System (OCS)
automatically turns the front passenger front
air bag on or off based on the classified
occupant weight category determined by

curtain air bag and the Emergency Tensioning
