Re
stra int sy stem functionality When
the ignition is switched on, a self-test is
per form ed, during which the0075 restra int sys‐
te m wa rning lamp lights up. It goes out no later
th an a few seconds af terth eve hicle is star ted.
The components of there stra int sy stem are then
functional. Malfunctioning
restra int sy stem A malfunction has occur
red in there stra int sys‐
te m if:
R the0075 restra int sy stem warning lamp does
not light up when the ignition is switched on
R the0075 restra int sy stem warning lamp
lights up continuously or repeatedly during a
journey 000A
WARNING Risk of inju ryor fata l injury
due toa malfunction in there stra int sys‐
tem
If th ere stra int sy stem is malfunctioning,
re stra int sy stem components may be trig‐ ge
red unintentionally or might not be trig‐
ge red at all in theev ent of an accident. This
may af fect the seat belt tensioner or airbag,
fo rex ample. 0007
Have there stra int sy stem checked and
re paired immediately at a qualified spe‐
cialist workshop. Fu
nction of there stra int sy stem in an acci‐
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, forex am‐
ple, this may result in suf ficiently high le vels of
ve hicle deceleration. Occupant saf

Self-test of automatic front passenger front
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
simul taneously.
The status of the front passenger front airbag is
displa yed af terth e self-tes t:
R PASSENGER AIR BAG ON lights up for
60 seconds, subsequently bo thindicator
lamps are off (PASSENGER AIR BAG ON and
OFF): the front passenger front airbag is able
to deploy in theeve nt of an accident.
R PASSENGER AIR BAG OFF lights up continu‐
ously: the front passenger front airbag is dis‐
abled. It will then not be deplo yed in the
eve nt of an accident.
If th ePA SSENGER AIR BAG ON indicator lamp is
off, on lythePA SSENGER AIR BAG OFF indicator
lamp sho wsthest atus of the front passenger front airbag. The
PASSENGER AIR BAG OFF indi‐
cator lamp may be lit continuously or be off.
If th ePA SSENGER AIR BAG OFF indicator lamp
and the0075 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
ch ild restra int sy stem tothe front passenger
seat. Ha veautomatic front passenger front air‐

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 front air‐
bag 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 there sult of the
classi fication.
- 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
seat. -
Ifth ePA SSENGER AIR BAG OFF indicator
lamp is lit continuously: the person of
smaller stature should not use the front
passenger seat. 000A
WARNING Risk of inju ryor death when
th ePA SSENGER AIR BAG OFF indicator
lamp is lit
If th ePA SSENGER AIR BAG OFF indicator
lamp remains lit af terth e sy stem self-test,
th e front passenger airbag is disabled. It will
not be deplo yed in theeve nt of an accident.
In this case, the front passenger airbag can‐
not per form its intended pr otective function,
e.g. when a person is seated in the front
passenger seat.
That person could, forex ample, come into
con tact wi th theve hicle interior, especially if
th e person is sitting too close tothe cockpit.
If th e front passenger seat is occupied,

front passenger seat is cor rect and the front passenger airbag is enabled or disa‐
bled in accordance with the person in the
front passenger seat.
