WARNING Risk of inju rydue tomalfunc‐
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. #
Have there stra int sy stem checked and
re paired immediately at a qualified spe‐
cialist workshop. Fu

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 Rollover
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
ot her:
R Seat belt tensioner: frontal impact, rear
impact, side impact, rollo ver
R Driver's airbag, front passenger airbag: fron‐
talimpact
R Knee airbag: frontal impact
R Side airbag: side impact
R Head airbag: side impact, rollo ver,frontal
impact
The front passenger airbag can only be depl oyed
in an accident if thePA SSENGER AIR BAG OFF

AIR BAG ON and OFF indicator lamps light up
simul taneously.
The status of the front passenger airbag is dis‐
pla yed via thePA SSENGER AIR BAG indicator

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 OFF 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

airbag. The PASSENGER AIR BAG OFF indicator
lamp may be lit continuously or be off. If
th ePA SSENGER AIR BAG OFF indicator lamp
and the6 restra int sy stem warning lamp
light up simultaneousl y,the front passenger seat
may not be used. Also in this case, do not fit a

R Ifth e front passenger seat is occupied byan
adult or a person with a stature cor respond‐
ing tothat of an adult, thePA SSENGER AIR
BA G OFF indicator lamp must be off. This
indicates that the front passenger airbag is
enabled.
If th ePA SSENGER AIR BAG OFF indicator
lamp is lit continuousl y,an adult or person
with a build cor responding tothat of an adult
should not use the front passenger seat.
Ins tead, they should use a rear seat.
R Ifth e front passenger seat is occupied by a
person of smaller stature (e.g. a teenager or
small adult), thePA SSENGER AIR BAG OFF
indicator lamp either lights up continuously
or remains off, depending on the classifica‐
tion.
- Ifth ePA SSENGER AIR BAG OFF indicator
lamp is off: mo vethe front passenger
seat as far back as possible, or the per‐
son of smaller stature should use a rear
