Restra int sy stem functionality
When the ignition is switched on, a sy stem self-
te st is per form ed, during which the0075
re stra int sy stem warning lamp lights up. It goes
out no later than a few seconds af terth eve hicle
is star ted. The components of there stra int sys‐

te m if:
RThe 0075 restra int sy stem warning lamp
does not light up when the ignition is
switched on.
RThe 0075 restra int sy stem warning lamp
lights up continuously or repeatedly during a
journe y.
0071
WARNING Risk of injury orfata l injury
due toa malfunction in there stra int sys‐
te m
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 theeve nt of an accident. This
may af fect the Emer gency Tensioning Device
or airbag, forex ample.
00BBHa ve 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:
RFr ontal impact
RRe ar impact
RSide impact
RRo llover 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 should
ta ke place in good time at thest art of the colli‐
sion.
Fa ctors whi chcan only be seen and measure d
af te r a collision has occur red cann otplay a deci‐
sive role in air bag deployment, nor do they pro‐
vide an indication of air bag deployment.
The vehicle may be deformed significantly with‐
out an air bag 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 air bag 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, theve hicle deceleration may be high enough
fo rth is to happen.
