Re
stra int sy stem functionality When
the ignition is switched on, a sy stem self-
te st is per form ed, during which the6
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 are then functional. Re
stra int sy stem malfunction R
The 6 restra int sy stem warning lamp
does not light up when the ignition is
switched on.
R The 6 restra int sy stem warning lamp
lights up continuously or repeatedly during a
journe y. &
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. #
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 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 should 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 cann otplay a deci‐
sive role in airbag deployment, nor do they pro‐
vide 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, theve hicle deceleration may be high enough
fo rth is to happen. 26

ling, as well as damaged doors, can lead to
th e function of the sensors being impaired.
The airbags might therefore not function

A deplo yed airbag no longer of fers any pro‐
te ction and cannot pr ovide the intended pro‐
te ctive function in theeve nt of an accident. #
Have theve hicle towe dto aqu alified

The au tomatic front passenger airbag shutoff is
able todetect whe ther the front passenger seat
is occupied bya person or a child restra int sys‐

disabled accordingly.
When ins talling a child restra int sy stem on the

R The entire base of thech ild restra int sy stem
must alw aysre st on the sitting sur face of the
