Occupant Safety - Mercedes-Benz SLS AMG Owner's Manual

WARNING
The restraint system may not work as inten-
ded if the following components have been
modified or work on these components has
not been performed correctly:
restraint system, consisting of the seat
R
belts and anchorages, belt tensioners, belt
force limiters, airbags
wiring
R
networked electronic systems
R
Airbags or belt tensioners could then fail, e.g.
in the event of an accident in which the decel-
eration force would normally be high enough
to trigger the systems, or they could be trig-
gered unintentionally. Never carry out any
modifications on the restraint systems.
Never tamper with electronic components
and their software.
SRS (Supplemental Restraint System)
Introduction
SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS consists of:
6 SRS warning lamp
R
airbags
R
airbag control unit (with crash sensors)
R
belt tensioners
R
belt force limiters
R
SRS warning lamp
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started.

WARNING
If SRS is malfunctioning, individual systems
may be triggered unintentionally or might not
be triggered in the event of an accident with
a high rate of vehicle deceleration.
A malfunction has occurred if:
the 6 SRS warning lamp does not light
R
up when the ignition is switched on.
the engine is running and the 6 SRS
R
warning lamp does not go out after a few
seconds.
the engine is running and the 6 SRS
R
warning lamp lights up again.
In this case, have SRS checked immediately
at a qualified specialist workshop. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose.
In particular, work relevant to safety or on
safety-related systems must be carried out at
a qualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags
In the event of a collision, the airbag control
unit evaluates important physical data related
to the vehicle deceleration or acceleration
during the first stage of the collision, such as:
duration
R
direction
R
magnitude
R
Based on the evaluation of this data, the air-
bag control unit pre-emptively triggers the
belt tensioners in the first stage.
i
The belt tensioners can only be triggered
if the seat belt tongues are correctly
engaged in the seat belt buckles.
If there is an even higher rate of vehicle decel-
eration or acceleration in a longitudinal direc-
tion, the front airbags are also deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluates vehi-
cle deceleration or acceleration in the event
of a collision. When the first deployment
