Operation of automatic front-passenger
front airbag deactivation
PASSENGER AIR BAG ON indicator lamp
:
PASSENGER AIR BAG OFF indicator lamp
;
The indicator lamps show you whether the co-
driver's front airbag is disabled or enabled.
Press the Start/Stop button once or twice or
X
turn the key to position 1 or 2 in the ignition
lock.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul-
taneously for approximately six seconds.
The indicator lamps then show the status of the
co-driver's front airbag.
PASSENGER AIR BAG ON is lit: the co-driver's
R
front airbag is enabled. If, in the case of an
accident, all deployment criteria are met, the
co-driver's front airbag is deployed.
PASSENGER AIR BAG OFF is lit: the co-driv-
R
er's front airbag is disabled. It will then not be
deployed in the event of an accident.
If the status of the co-driver's front airbag
changes while the vehicle is in motion, an airbag
display message appears in the instrument clus-
ter (
page 263). When the co-driver's seat is
Y
occupied, always pay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status
of the co-driver's front airbag both before and
during the journey.
If a person is occupying the co-driver's seat,
they must sit:
with the seat belt fastened correctly
R
in an almost upright position with their back
R
against the seat backrest
with their feet resting on the floor, if possible
R
If the co-driver does not observe this, the auto-
matic co-driver's front airbag deactivation sys-
tem may be influenced, for example if the co-
driver:
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
This or similar behaviour can cause the co-driv-
er's front airbag to be deactivated when it
should not be. In this case, PASSENGER AIR BAG
OFF indicator lamp lights up continuously. The
co-driver's front airbag is then not deployed in
an accident.
G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp
is lit, the front-passenger front airbag is disa-
bled. It will not be deployed in the event of an
accident and cannot perform its intended pro-
tective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always make sure that:
the classification of the person in the front-
R
passenger seat is correct and that the front-
passenger front airbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
the front-passenger seat has been moved
R
back as far back as possible.
the person is seated correctly.
R
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front airbag is correct.
G
WARNING
If you secure a child on the co-driver's seat in
a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The child
could be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
