The indicator lamps inform you whether the
front-passenger front air bag is deactivated or
enabled.
Press the Start/Stop button once or twice,
X
or turn the SmartKey to position 1 or 2 in
the ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps must
light up simultaneously for approximately six
seconds.
The indicator lamps display the status of the
front-passenger front air bag.
PASSENGER AIR BAG ON lights up for
R
60 seconds, subsequently both indicator
lamps are off (PASSENGER AIR BAG ON and
OFF): the front-passenger front air bag is
able to deploy in the event of an accident.
PASSENGER AIR BAG OFF lights up: the
R
front-passenger front air bag is deactivated.
It will then not be deployed in the event of
an accident.
If the PASSENGER AIR BAG ON indicator lamp
is off, only the PASSENGER AIR BAG OFF indi-
cator lamp shows the status of the front-
passenger front air bag. The PASSENGER AIR
BAG OFF indicator lamp may be lit continu-
ously or be off.
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 213). When the front-
Y
passenger seat is occupied, always pay atten-
tion to the PASSENGER AIR BAG OFF indicator
lamp. Be aware of the status of the front-
passenger front air bag both before and during
the journey.

WARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag
is disabled. It will not be deployed in the
event of an accident and cannot perform its
intended protective function. A person in the
front-passenger seat could then, for exam-
ple, come into contact with the vehicle's
interior, especially 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 ensure that:
the classification of the person in the
R
front-passenger seat is correct and the
front-passenger front air bag is enabled or
disabled 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.

Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct.

WARNING
If you secure a child in a rearward-facing
child restraint system on the front-
passenger seat and the PASSENGER AIR
BAG OFF indicator lamp is off, the front-
passenger front air bag can deploy in the
event of an accident. The child could be
struck by the air bag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been deactivated. The PASSENGER
AIR BAG OFF indicator lamp must be lit.
NEVER use a rearward-facing child restraint
on a seat protected by an ACTIVE FRONT
AIRBAG in front of it; DEATH or SERIOUS
INJURY to the child can occur.
If the PASSENGER AIR BAG OFF indicator lamp
stays off, do not install a rearward-facing child
restraint system on the front-passenger seat.
You can find more information on OCS under
"Problems with the Occupant Classification
System" ( page 51).
