Seat belts, together with belt tensioners, belt
force limiters and airbags, are coordinate d
restraint systems. They reduce the risk of
injury in critical driving situations and thereby
increase your driving safety. However, seat
belts and airbags are generally unable to pre-
vent injuries caused by 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 86)
R the seat belt has been fastened properl y
( Y page 98)
R the airbags can inflate properly if they ar e
deployed (Y page 49)
R the steering wheel is adjusted properl y
( Y page 92)
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, bu tdoes 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 situation
s
airbag deployment would not increase th e
protection afforded to vehicle occupants,
provided they are wearing their seat belt
correctly.
On the other hand, airbag deployment only
provides increased protection if the seat
belt is worn correctly, because:
R the seat belt helps to keep the vehicl e
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 propelle d
towards the force of the impact, and is
thus better suited to prevent injury
Thus, in accident situations where an air-
bag is deployed, it only provides protection
in addition to the seat belt if the seat belt
is being worn correctly. G
Risk of injury
The restraint system may not work as inten-
ded if the following components have bee n
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 wirin g
R networked electronic system s
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
carry out any modifications on the restraint
systems. Never tamper with electronic
components and their software. G
Risk of accident and injury
Always have maintenance work carried ou t
at a qualified specialist workshop whic h
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. Safety

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)

the vehicle when the belt tongue is

sion if the vehicle decelerates or acceler- Safety

during the initial stages of the collision
When the belt tensioners are triggered, you
will hear a bang, which will not cause any
harm to your hearing, and a small amount of
powder may also be released. The =warn-
ing lamp lights up. G
Risk of injury
If the seat belt tensioners have been trig -
gered, they provide no additional protec -
tion in the event of another accident.
Therefore, have belt tensioners which have
been triggered replaced at a qualified spe-
cialist workshop .
Comply with safety regulations when dis-
posing of belt tensioners. Any Mercedes-
Benz Service Centre can provide details of
these regulations.
Airbag s Airbag deployment slows down and restricts
the movement of the vehicle occupant.
When the airbags are triggered, you will hear
a bang, which will not cause any harm to your
hearing, and a small amount of powder ma y
also be released. The =warning lamp

tion of the airbags
. G
Risk of injury
Airbags provide additional protection; they
are not, however, a substitute for the sea t
belts.
Observe the following notes to reduce the
risk of serious or even fatal injury if an air-
bag is deployed:
R Vehicle occupants — in particular preg-
nant woman — must wear their seat belt
correctly at all times and lean back
against their backrest, which should be
positioned as close to the vertical as pos-
sible. The head restraint must support
the back of the seat occupant's head at
about eye level.
R Always secure children less tha n
1.50 mtall or under 12 years of age in
suitable child restraint systems.
R All vehicle occupants must select a sea t
position that is as far away from the air-
bag as possible. The driver's seat posi-
tion must allow the vehicle to be driven
safely. The driver's chest should be as far
away from the middle of the driver's fron t
airbag cover as possible. R
Move the front-passenger seat as far
back as possible, in particular, if a child
is secured in a child restraint system on
the seat.
R Vehicle occupants – in particular, chil-
dren – must not lean their head into the
area of the window in which the sidebag/
windowbag is deployed.
R Rearward-facing child restraint systems
must not be fitted to the front-passenger
seat unless the front-passenger front air-
bag has been disabled. On the front-
passenger seat, the front-passenger
front airbag is only deactivated if a child
restraint system with automatic child
seat recognition is fitted to the front-
passenger seat *.The 5 PASSENGER
AIRBAG OFF warning lamp must be li t
constantly .
If either the rearward-facing child
restraint system or the front-passenger
seat* of your vehicle does not have auto-
matic child seat recognition, childre n
must be secured in a child restraint sys-
tem on a suitable seat in the rear. If you
secure a forward-facing child restraint
system to the front-passenger seat, you Safety
