Occupant safety
The 75 indicator lamp 1 will be
illuminated, except with the SmartKey
removed or in starter switch position 0.
Self-test Occupant Classification Sys-
tem
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 75 indicator lamp 1
located 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
75 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 75 indicator lamp
will illuminate and not go out.
Warning! G
If the 1 indicator lamp and the
75 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.
Contact an authorized Mercedes-Benz
Center.
ț Do not place more than 4.4 lbs (2 kg)
into the ruffled storage bag on the back
of the front passenger seat. Otherwise,
the OCS may not be able to properly ap-
proximate the occupant weight
category.
ț Do not place objects under and/or
around the front passenger seat.
ț Do not hang anything from or attach any
items to the seats.
ț Do not stuff objects such as books be-
tween the middle console and the front
passenger seat.
ț Do not move the front passenger seat
backwards against stiff objects.
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.
