However, the trig
gering of each ind ividual
system depends on the following factors as
determined in the initial stages of the col-
lision:
R the type of accident
- head-on collision
- sid eimpact
- rea rimpact
- Cabriolet: overturn
R thes everity of the accident, in particular
- the vehicle's rat eofdeceleration
- the vehicle's rat eofacceleration
Th ev ehicle deceleration or acceleration and
the direction of force ar ebasicall ydeter-
min edby:
R the distri bution of force sduring the colli-
sion
R the collision angle
R the deform ation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle collides
Factors which can only be see nand measured
after acollision has occ urreddon ot play a
decisive role in the deployment of an airbag
nor do they provid eanindicatio nofairbag
deployment.
The vehicle may be deformed significantly,
e.g. the bonnet or the wing, withou tanairbag
being deployed. This is the case if only parts
which are relatively easily deformed are affec-
ted and the deploymen tthreshol disnot
reached. Conversely ,airbags may be
deployed even though the vehicle suffer sonly
minor deformation. Thi sisthe case if, for
example, ver yrigid vehicle parts such as lon-
gitudinal body member sare hi tand sufficient
deceleratio noccurs as aresult. Airbags
Important safety notes Airbag deployment slows down and restricts
the movemen
tofthe vehicle occupant.
If the airbags ar edeployed, you will hear a
bang and asmall amount of powder may also
be released. Only in rare cases will th ebang
affect your hearing. The powde rthat is
released generally does not constitute a
healt hhazard. The 6SRS warning lamp
lights up.
The SRS/AIRBAG symbol indicates the instal-
lation location of the airbags. G
Risk of injury
Airbags provide additional protection; they
are not, however, asubstitute for seat belts.
Observe the following notes to reduce the risk
of serious or even fatal injury caused by airbag
deployment:
R All vehicle occupants –inparticular ,preg-
nant women –must wear their seat belt
correctly at all times and lean back against
the backrest, which should be posi tioned
as close to th evertical as possible. The
head restraint must support th eback of the
head at about eye level.
R Always secur echildren less than 1.50 mtall
and under 12 years of age in suitable child
restraint systems.
R All vehicle occupant smust select aseat
position that is as far away from the airbag
as possible. The driver' sseat position must
allow the vehicle to be driven safely .The
driver's chest should be as fa raway from
the centre of the driver' sfront airba gcover
as possible.
R Move the fr ont-passengers eat as far back
as possible. This is especially impor tantif
you have secured achild in achild rest raint
system on the front-passenger seat. 34
