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
