Occupant safety
36 Occupant safety
Notes on occupant safety
Seat belts, together with belt tensioners, belt
force limiters and airbags, are coordinated
restraint systems. They reduce the risk of
injury in defined accident situations and
thereby increase occupant safety. However,
seat belts and airbags generally do not pro-
tect against objects penetrating the vehicle
from the outside.
To ensure that the restraint systems can
deliver their full potential protection, you
should ensure that:
R the seat and head restraint are adjusted
properly (Y page 63)
R the seat belt has been fastened properly
(Y page 73)
R the airbags can inflate properly if they are
deployed (Y page 39)
R the steering wheel is adjusted properly
(Y page 70)
R the restraint systems have not been modi-
fied
i An airbag increases the protection of
vehicle occupants wearing a seat belt.
However, airbags are only an additional restraint system which complements, but
does not replace, the seat belt. All vehicle
occupants must wear their seat belt cor-
rectly at all times, even if the vehicle is
equipped with airbags. This is because - on
the one hand - airbags are not deployed in
all types of accident, as in some situations
airbag deployment would not increase the
protection afforded to vehicle occupants,
provided they are wearing their seat belt
correctly. On the other hand, airbag deploy-
ment only provides increased protection if
the seat belt is worn correctly because:
R
the seat belt helps to keep the vehicle
occupant in the best position in relation
to the airbag
R for example, in a head-on collision, the
seat belt can more adequately prevent
the occupant from being propelled
towards the force of the impact, and is
thus better suited to prevent injury
Therefore, in accident situations where an
airbag is deployed, it only provides protec-
tion in addition to the seat belt if the seat
belt is being worn correctly. G
Risk of accident and injury
Always have maintenance work carried out
at a qualified specialist workshop which has the necessary specialist knowledge
and tools to carry out the work required.
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. 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.
G
Risk of injury
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:
R restraint system, consisting of the seat
belts and anchorages, belt tensioners,
belt force limiters, airbags
R wiring
R networked electronic systems
Airbags or belt tensioners could then fail,
e.g. in the event of an accident in which the
deceleration force would normally be high
enough to trigger the systems, or they
could be triggered unintentionally. Never Safety

systems.
Never tamper with electronic components
and their software.
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. It can also reduce
the forces to which occupants are subjected
during an accident.
The SRS consists of:
R The 1 warning lamp
R belt tensioners
R belt force limiters
R airbags
The 1 1warning 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
1 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. G
Risk of injury
If SRS is malfunctioning, individual systems
may be activated unintentionally or not be
deployed in the event of an accident with
heavy braking.
A malfunction has occurred if the 1
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 first
stage 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.
Your vehicle has adaptive, dual stage front
airbags. When the first activation threshold is
reached, the front airbag is filled with enough
propellant gas to reduce the risk of injuries.
The front airbag is only fully inflated if a sec-
ond threshold is reached within a few milli-
seconds, due to the control unit having detec-
ted further deceleration.
Criteria for triggering belt tensioners and
airbags
In the first stage of a collision, the airbag con-
trol unit evaluates the duration and direction
of vehicle acceleration or deceleration in
order to determine whether it is necessary to
trigger the belt tensioner and/or airbag.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration of the vehicle. This proc-
ess is pre-emptive in nature as the airbag
must be deployed during – and not at the end
of – the collision.
i
Airbags are not deployed in all types of
accidents. They are controlled by complex
sensor technology and evaluation logic.
This process is pre-emptive in nature as Safety
