Self-test Occupant Classification
System
After turning the SmartKey in the starter
switch to position 1 or 2 or pressing the
KEYLESS-GO* start/stop button (Canada
only) once or twice, the
5/ indicator
lamp 1 illuminates. If an adult occupant is
properly sitting on the front passenger
seat and the system senses the occupant
as being an adult, the
5/ indicator
lamp will illuminate and go out after ap-
proximately 6 seconds.
If the seat is not occupied and the system
senses the front passenger seat as being
empty, the
5/ indicator lamp will
illuminate and not go out.
Warning! G
If the = indicator lamp and the
5/indicator lamp are lit at the same
time, there is a malfunction in the Occupant
Classification System. The front passenger
front air bag will be deactivated in this case.
Have the system checked as soon as possi-
ble by qualified technicians. Contact an au-
thorized 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:
ț Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.
ț 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 ap-
proximate the occupant’s weight
category.
ț Read and observe all warnings in this
chapter.
Warning! G
If the 5/indicator lamp should not il-
luminate, the system is not functioning. You
must see an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat.
