Occupant safety

Prerequisite
To be classified correctly, the front passenger
must sit:
with the seat belt fastened correctly
R
in an almost upright position with their
R
back against the seat backrest
with their feet resting on the floor, if possi-
R
ble
If the front passenger does not observe these
conditions, OCS may produce a false classi-
fication, e.g. because the front passenger:
transfers their weight by supporting them-
R
selves on a vehicle armrest
sits in such a way that their weight is raised
R
from the seat cushion
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the correct positioning of
the child restraint system. Never place
objects under or behind the child restraint
system, e.g. cushions. Fully retract the seat
cushion length. 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 a load by the head
restraint. Adjust the angle of the seat back-
rest and the head restraint position accord-
ingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation instruc-
tions.

must light up simultaneously for approx-
imately six seconds.
The indicator lamps display the status of the
front-passenger front air bag.
PASSENGER AIR BAG ON lights up: the
R
front-passenger front air bag is enabled. If,
in the event of an accident, all deployment
criteria are met, the front-passenger front
air bag is deployed.
PASSENGER AIR BAG OFF lights up: the
R
front-passenger front air bag is deactiva-
ted. It will then not be deployed in the event
of an accident.
If the status of the front-passenger front air
bag changes while the vehicle is in motion, an
air bag display message appears in the instru-
ment cluster ( page 264). When the front-
Y
passenger seat is occupied, always pay atten-
tion to the PASSENGER AIR BAG ON and
PASSENGER AIR BAG OFF indicator lamps. Be
aware of the status of the front-passenger
