Occupant safet
y 47In particular, work relevant to safety or on
safety-related systems must be carried out
at a qualified specialist workshop. If this
work is not carried out correctly, the oper-
ating safety of your vehicle may be affec -
ted. There is a risk of an accident and injury .SRS (Supplemental Restraint System)
The SRS reduces the risk of occupants com-
ing into contact with the vehicle's interior in
the event of an accident.
The SRS consists of:
R The SRS warning lamp =
R Belt tensioners
R Belt force limiters
R Airbag s
The SRS warning lamp ==The SRS functions are checked regularly
when you turn on the ignition and when the
engine is running. Malfunctions can therefore
be detected in good time.
The = warning lamp in the instrumen t
cluster lights up when you switch on the igni -tion and goes out a few seconds after the
engine is started
. G
Risk of injury
If SRS is malfunctioning, individual systems
may be activated unintentionally or not be
triggered in the event of an accident with
heavy braking.
A malfunction has occurred if the =
warning lamp:
R does not light up when you switch on the
ignition
R does not go out after the engine has been
running for a few seconds
R lights up again once the engine is running
In this case, have SRS checked immedi-
ately at a qualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags In the event of a collision, the sensor in the
airbag control unit evaluates important phys-
ical data such as duration, direction and force
of the vehicle deceleration or acceleration.
Based on the evaluation of this data and
depending on the vehicle's rate of longitudi-
nal deceleration in a collision, in the firs
tstage the airbag control unit pre-emptively
triggers the belt tensioners.
The front airbags are only deployed if there is
an even higher rate of vehicle deceleration in
a longitudinal direction.
If your vehicle is fitted with adaptive dual-
stage front airbags, the front airbag is filled
with enough gas to reduce the risk of injuries
at the first deployment threshold. The front
airbag is only fully inflated if a second thresh-
old is reached within a few milliseconds due
to the control unit having detected further
deceleration.
i
The front belt tensioners can only be trig-
gered if the belt tongue is correctly
engaged in the seat belt buckle.
Criteria for triggering belt tensioners and
airbags
In the first stages of a collision, the sensor in
the airbag control unit evaluates physical
data such as duration, direction and rate of
vehicle deceleration or acceleration in order
to determine whether it is necessary to trig-
ger the belt tensioners and/or airbags.
The belt tensioner and airbag triggerin g
thresholds are variable and are adapted to the
rate of deceleration of the vehicle. This proc-
ess is pre-emptive in nature as the airba g Safety

must be deployed during – and not at the end
of – the collision
.
i Airbags are not deployed in all types of
accident. They are controlled by comple x
sensor technology and evaluation logic.
This process is pre-emptive in nature as
airbag deployment must take place during
the impact and must be adapted to provide
calculated, additional protection for the
vehicle occupants. Not all airbags are
deployed in an accident.
The different airbag systems work inde-
pendently of each other. However, the
deployment of each individual system will
depend on the type of accident determined
by the control system in the first stages of
the collision (head-on collision, side impact
and overturn) and the extent of the acci-
dent (in particular, the vehicle's rate of
deceleration or acceleration).
The rate of vehicle deceleration or accelera-
tion and the direction of the force are basi-
cally determined by:
R the distribution of forces during the colli -
sion
R the collision angle R
the deformation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle has collided, e.g. the other vehi-
cle
Factors which can only be seen and measured
after the collision has taken place do not play
a decisive role in the deployment of an airbag,
nor do they provide an indication of it.
The vehicle may be considerably deformed
without an airbag being deployed if, for exam-
ple, only relatively easily deformable parts
such as the bonnet or wings have been hit and
the required rate of deceleration has not been
reached. It is also possible that airbags ma y
be deployed even though the vehicle is only
slightly deformed if, for example, very rigid
vehicle parts such as the longitudinal mem-
bers are hit in an accident and the rate of
deceleration is sufficient .
Belt tensioners, belt force limiters The front seat belts and the outer seat belts
in the rear are equipped with belt tensioners.
! Do not engage the seat belt tongue in the
buckle on the front-passenger seat if the
seat is not occupied. Otherwise the belt tensioner could be activated in an emer-
gency.
If the seat belt is also equipped with a belt
force limiter, the force exerted by the sea t
belt on the seat occupant is reduced.
Belt tensioners tighten the seat belts in an
accident, pulling them close against the body.
i Belt tensioners do not correct incorrect
seat positions or incorrectly fastened sea t
belts.
Belt tensioners do not pull occupants back
towards the backrest.
The front belt force limiters are synchronised
with the front airbags, which spread the
forces exerted by the belt force limiters on
the occupant over a greater area.
When the ignition is switched on, the belt ten -
sioner is triggered:
R only if the restraint systems are operational
(the = warning lamp lights up after th e
ignition is switched on and goes out onc e
the engine is running)( Ypage 47)
R for each three-point seat belt in the front of
the vehicle when the belt tongue is
engaged in the buckle
R in the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler- Safety
