seat belt, ahead bag may be deployed in other
accident situations (Y page 50).
The head bag on the front-passenger side
deploysunder the following conditions:
R
the OCS system detects that the front-
passenger seat is occupied or
R
the seat belt buckle tongue is engaged in
the belt buckle of the front-passenger seat
If the belt tongue is engaged in the belt
buckle, the head bag on the front-passenger
side deploysifanappropriate accident situa-
tion occurs. In this case, deployment is inde-
pendent of whether the front-passenger seat is
occupied or not.
Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-
egorizes the person in the front-passenger
seat. Depending on that result, the front-
passenger front air bag and front-passenger
knee bag are either enabled or deactivated.
The system does not deactivate:
R
the side impact air bag
R
the headbag
R
the EmergencyTensioning Devices
Requirements
To be classified correctly, the front passenger
must sit:
R
with the seat belt fastened correctly
R
in an almost upright position with their back
against the seat backrest
R
with their feet resting on the floor, if possi-
ble
If the front passenger does not observe these
conditions, OCS may produce afalse classifi-
cation, e.g. because the front passenger:
R
transfers their weight by supporting them-
selves on avehicle armrest
R
sits in such away that their weight is raised
from the seat cushion
If you install achild restraint system on the
front-passenger seat, be sure to observe the
correct positioning of the child restraint sys-
tem. Never place objects under or behind the
child restraint system, e.g. acushion. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the forward-
facing child restraint system must lie as flat as
possible against the backrest of the front-
passenger seat.
The child restraint system must not touch the
roof or be subjected to aload by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation and operat-
ing instructions.

Press the Start/Stop button once or twice,
or turn the SmartKey to position 1 or 2 in

The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps must
light up simultaneouslyfor approximately six
