gered unintentionally
.Never carry out any
modifications on the restraint systems.
Never tamper with electronic components
and their software. SRS (Supplemental Restraint System)
Introd uction SRS reduces the risk of occupants coming
into contact with the vehicle's interio
rinthe
even tofana ccident. It can als oreduce the
effect of the forces to which occupant sare
subjected during an accident.
SRS consists of:
R 6 SRS warning lamp
R airbags
R airbag con trol unit (with crash sensors)
R belt tensioners
R belt force limiters
SRS warning lamp SRS func
tions ar echecked regularly when
you switc honthe ignition and when the
engin eisrunning. 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 afew seconds
after the engine is star ted. G
Risk of inju
ry
If SR Sism alfunctioning, individual systems
may be activated unintentionally or may not
be triggered in the event of an accident with
ah igh rate of vehicle deceleration.
Am alfunction has occurred if:
R the 6 SRS warning lamp does not light
up after the ignition is switched on.
R the engine is runnin gand the 6SRS
warning lamp doe snot go out after afew
seconds.
R the engine is runnin gand the 6SRS
warning lamp lights up again. In this case, have SRS checked immediately
at
aq ualified specialist workshop .Mercedes-
Benz recommends that you use aMercedes-
Benz Servic eCentr efor this purpose.
In particular ,work relevant to safet yoron
safety-related systems must be carried out at
aq ualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags In the event of
acollision ,the airbag con trol
unit evaluates important physical data relat-
ing to the vehicle deceleration or acceleration
during the first stage of the collision, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data ,the air-
bag con trol unit pre-emptivel ytriggers the
belt tensioners in th efirst stage.
i The belt tensioners can only be triggered
if the seat belt tongues are correctly
engaged in the seat belt buckles.
The front airbags are also deployed if there is
an even higher rate of vehicle deceleration in
al ongitudinal direction.
Your vehicle has adaptive, dual-stage front
airbags. In the even tofacollision, the airbag
control unit evalu atesthe vehicle decelera-
tion. Whe nthe first deploymen tthreshol dis
reached, th efront airbag is fille dwith enough
gas to reduce the risk of injuries. The front
airbag is fully deployed if asecon ddeploy-
men tthreshold is exceeded withi nafew mil-
liseconds.
Th eb elt tensioner and airbag triggering
thresholds are variable and are adapted to the
rat eofd eceleration of the vehicle. This proc-
ess is pre-emptiv einnature. The triggering
process must take place in good time at the
start of the collision.
i Not all airbags are deployed in an acci-
dent. The different airbag systems work
independently of each other. Occupant safety

However, the trig
gering of each ind ividual
system depends on the following factors as
determined in the initial stages of the col-
lision:
R the type of accident
- head-on collision
- sid eimpact
- rea rimpact
- Cabriolet: overturn
R thes everity of the accident, in particular
- the vehicle's rat eofdeceleration
- the vehicle's rat eofacceleration
Th ev ehicle deceleration or acceleration and
the direction of force ar ebasicall ydeter-
min edby:
R the distri bution of force sduring the colli-
sion
R the collision angle
R the deform ation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle collides
Factors which can only be see nand measured
after acollision has occ urreddon ot play a
decisive role in the deployment of an airbag
nor do they provid eanindicatio nofairbag
deployment.
The vehicle may be deformed significantly,
e.g. the bonnet or the wing, withou tanairbag
being deployed. This is the case if only parts
which are relatively easily deformed are affec-
ted and the deploymen tthreshol disnot
reached. Conversely ,airbags may be
deployed even though the vehicle suffer sonly
minor deformation. Thi sisthe case if, for
example, ver yrigid vehicle parts such as lon-
gitudinal body member sare hi tand sufficient
deceleratio noccurs as aresult. Airbags
Important safety notes Airbag deployment slows down and restricts
the movemen
tofthe vehicle occupant.
If the airbags ar edeployed, you will hear a
bang and asmall amount of powder may also
be released. Only in rare cases will th ebang
affect your hearing. The powde rthat is
released generally does not constitute a
healt hhazard. The 6SRS warning lamp
lights up.
The SRS/AIRBAG symbol indicates the instal-
lation location of the airbags. G
Risk of injury
Airbags provide additional protection; they
are not, however, asubstitute for seat belts.
Observe the following notes to reduce the risk
of serious or even fatal injury caused by airbag
deployment:
R All vehicle occupants –inparticular ,preg-
nant women –must wear their seat belt
correctly at all times and lean back against
the backrest, which should be posi tioned
as close to th evertical as possible. The
head restraint must support th eback of the
head at about eye level.
R Always secur echildren less than 1.50 mtall
and under 12 years of age in suitable child
restraint systems.
R All vehicle occupant smust select aseat
position that is as far away from the airbag
as possible. The driver' sseat position must
allow the vehicle to be driven safely .The
driver's chest should be as fa raway from
the centre of the driver' sfront airba gcover
as possible.
R Move the fr ont-passengers eat as far back
as possible. This is especially impor tantif
you have secured achild in achild rest raint
system on the front-passenger seat. 34

Bel ttensioners, belt force limiters The seat belts are fitted with belt tensioners.
!
If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.

Risk of injury

To ensure that the automatic child seat rec-

system cannot perform its intended protec-
