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.

Warning!
If the = indicator lamp and the
5/ indicator lamp are lit at the same
time, there is a malfunction in the OCS. The
front 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 front 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 front passenger seat as being
empty, the 5/ indicator lamp will
illuminate and not go out.
G
Warning!
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
front passenger seat.
For more information, see the “Practical
hints” section (Y page 348).
G
Warning!
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the OCS. The bottom
and back of the child seat must make full
contact with the passenger seat cushion
and backrest.
If necessary, adjust the tilt of the passenger
seat backrest.
