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 once or
twice, the 56 indicator lamp
located in the center console illuminates. If
an adult occupant is properly sitting on the
front passenger seat and the system
senses the occupant as being an adult,
the 56 indicator lamp will
illuminate and go out after
approximately 6 seconds.
If the seat is not occupied and the system
senses the front passenger seat as being
empty, the 56 indicator lamp will
illuminate and not go out.
Warning! G
If the 1 indicator lamp and the
56 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.
