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

R
Children less than 1.50 mtall or under 12
years of age cannot wear the seat belts
properly. Therefore, they always should be
secured in asuitable child restraint system
on asuitable vehicle seat. You can find
more information under "Children in the
vehicle" in the "Safety" section of the Own-
er's Manual. Follow the manufac turer's
installatio ninstructions whe nfitting the
child restraint system.
R Do not secure any objects with aseat belt
if the seat belt is also being used by one of
the vehicle's occupants. G
Risk of injury
The seat belt does not offer the intended level
of protection unless the back rest is almost
ver tical. Under certain circumstances, this
coul dcause severe or even fatal injuries in the
event of an accident.
Befor estarting ajourney, mak esure that the
seat is properly adjusted and that the back-
rest is almost vertical. G
Risk of injury
Ad irtyo rdamaged seat belt or aseat belt that
has been subjected to aload in an accident
or which has been modified no longer offers
the intended level of protection. Un dercertain
cir cumstances, this could caus esever eor
even fatal injuries in the even tofanaccident.
For thi sreason, check regularly that the seat
belts are not damaged or dirty.
Alway shaved am aged sea tbelts or seat belts
that have been subjected to aload in an acci-
dent replaced at aqualified specialist work-
shop. Consult aqualified 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 Ser vice Centre for thi spur-
pose.
For safety reasons, Mercedes -Benz recom-
mends that you only use seat belts which have
been approved by Mercedes-Benz for your
vehicle. Fastening seat belts The seat-belt extender for the driver and front
passenger helps you fasten your seat belt.
Example: Coupé

You can also activa teseat -belt extender :
by using the seat-belt extender button in the

Risk of inju
ry
The seat-belt extender must be ret racted
whe nthe vehicle is in motion .Only then can
the sea tbelt fit properly on the body and per-
for mi ts protective function.
Seat-belt extender :is retracted again if:
R the belt tongue is engaged in the sea tbelt

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
