WARNING Risk of injury duetomalfunc‐
tions in there stra int sy stem
Components in there stra int sy stem may be
activated unintentionally or not deploy as
intended in an accident. #

dent How
there stra int sy stem works is de term ined by
th e se verity of the impact de tected and the type
of accident anticipated:
R Frontal impact
R Rear impact
R Side impact
R Onlyfor cer tain countries: rollo ver
The activation thre sholds forth e components of
th ere stra int sy stem are de term ined based on
th eev aluation of the sensor values measured at
va rious points in theve hicle. This process is pre-
em ptive in nature. The triggering/deployment of
th e components of there stra int sy stem must
ta ke place in good time at thest art of the colli‐
sion.
Fa ctors whi chcan only be seen and measu red
af te r a collision has occur red do not play a deci‐
sive role in the deployment of an airbag. Nordo
th ey prov ide an indication of airbag deployment.
The vehicle may be deformed significantly with‐
out an airbag being deplo yed. This is the case if only parts which are
relatively easily deformed
are af fected and thera te ofvehicle deceleration
is not high. Con versely, an airbag may be
deplo yedev en though theve hicle suf fers only
minor deformation. If very rigid vehicle parts
such as longitudinal members are hit, this may
re sult in suf ficiently high le vels of vehicle decel‐
eration.
Depending on the de tected deployment situa‐
tion, the components of there stra int sy stem can
be activated or deplo yed independently of each

impact, side impact, rollo ver 1

Self-test of automatic front passenger airbag
shutoff
When
the ignition is switched on, a self-test is
per form ed during which the two PASSENGER
AIR BAG ON and OFF indicator lamps light up

lamps af terth e self-tes t:
R ON is lit: the front passenger airbag may
deploy during an accident.
The indicator lamp goes out af ter appro x‐
ima tely 60 seconds.
R ON and OF F are not lit: the front passenger
airbag may deploy during an accident.
R OFF is lit: the front passenger airbag is disa‐
bled. It will then not be deplo yed in theev ent
of an accident.
If th ePA SSENGER AIR BAG ON indicator lamp is
off, on lythePA SSENGER AIR BAG OFF indicator
lamp sho ws thest atus of the front passenger
