Self-test Occupant Classification
System
After turning the SmartKey in the starter
switch to position 1 or 2, the
56 indicator lamp 1 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.
For more information, see “Lamp in center
console” (
୴ page 357).
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.
Contact 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 Cen-
ter.
ț Read and observe all warnings in this
chapter.
Warning! G
If the 56 indicator lamp should not
illuminate, the system is not functioning.
You must see an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat.
Warning! G
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the Occupant Classifi-
cation System. The bottom of the child seat
must make full contact with the passenger
seat cushion. An incorrectly mounted child
seat could cause injuries to the child in case
of an accident, instead of increasing protec-
tion for the child.
Follow the manufacturer’s instructions for
installation of child seats.
