be illuminated, except with the SmartKey
removed from the starter switch or with

Warning!
If the = indicator lamp and the
59 indicator lamp are lit at the
same time, there is a malfunction in the
Occupant Classification System. The front

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 by
an authorized Mercedes-Benz Center.
In order to ensure proper operation of the
air bag system and OCS:
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
approximate the occupant weight
category.
Do not place objects under and/or
around the front passenger seat.

Do not hang anything from or attach any
items to the seats.
Do not stuff objects such as books be-
tween the middle console and the front
passenger seat.
Do not move the front passenger seat
backwards against stiff objects.
Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.
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 cate-
gory.
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.
Read and observe all warnings in this
chapter.
