time, there is a malfunction in the Occupant
Classification System. The front passenger

In order to ensure proper operation of the
air bag system and OCS:
Have the system checked as soon as
possible by qualified technicians.

position with your back against the seat
backrest.
Do not lean on the armrests or lift your-
self from the seat by using the handle
over the door as this may cause the OCS
to be unable to correctly approximate
the occupant weight category.
Only have the seat repaired or replaced
by an authorized Mercedes-Benz
Center.
