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 1 lo-
cated in the center console illuminates. If
an adult occupant is properly sitting on the
front passenger seat and the system sens-
es the occupant as being an adult, the
56 indicator lamp will illuminate
and go out after approximately six
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.
In order to ensure proper operation of the
air bag system and OCS:
ț Have the system checked as soon as
possible by qualified technicians. Con-
tact an authorized Mercedes-Benz
Center.
ț Sit properly belted in a nearly upright
position with your back against the seat
backrest.
ț 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.
ț Only have the seat repaired or replaced
by an authorized Mercedes-Benz
Center.
ț Read and observe all warnings in this
chapter.
