that the seat was occupied by a small
individual (such as a young teenager or a
small adult) or a child who weighs more
than the weight of a typical 12-month-old
child in a standard child restraint – both of
which are instances where the system may
suppress deployment of the passenger

Passenger front air bag off indicator lamp
The
5/
indicator lamp
1
will be
illuminated, except with the SmartKey
removed from the starter switch or with the
starter switch in position
0.
If the
1
indicator lamp and the
5/
indicator lamp are lit at the same
time, there is a malfunction in the OCS. The
passenger front air bag will be deactivated
in this case. Have the system checked as
soon as possible by qualified technicians.
Contact an authorized Mercedes-Benz
Center.
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
While seated, an occupant should not
position him/herself in such a way as to
cause the occupant’s weight to be lifted
from the seat bottom as this may result
in the OCS being unable to correctly
approximate the occupant’s weight
category.
R
Read and observe all warnings in this
chapter.
Occupant Classification System Self-
test
After turning the SmartKey in the starter
switch to position
1 or 2 or pressing the
KEYLESS-GO start/stop button once or
twice, the
5/
indicator lamp
illuminates. If an adult occupant is properly
sitting on the passenger seat and the system
classifies the occupant as an adult, the
5/
indicator lamp will illuminate and
go out after approximately 6 seconds.
If the seat is not occupied and the system
classifies the passenger seat as being empty,
the
5/
indicator lamp will illuminate
and not go out.
If the
5/
indicator lamp does not
illuminate, the system is not functioning.
You must contact an authorized Mercedes-
Benz Center before seating any child on the
passenger seat.

hints” section (
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
