.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

Front-passenger front airbag ;is only
deployed if the front-passenger seat is occu-
pied or if the 4PASSENGER AIRBA GOFF
indicato rlamp in the centre console is not lit
(Y page 46). This means that achild
restraint system with automatic chil dseat
recognition has not been fitted to the front-
passenger seat or has been fitted incorrectly.
! Do not place heavy object sonthe front-
passenger seat. This could cause the sys-
tem to identify the seat as being occupied.
In the even tofanaccident, the restraint
systems on the front-passenger sid eare triggered
.Have restraint systems that have
been triggered replaced.
Driver's kneebag i
The driver' skneebag is only available in
certain countries.
The driver's kneebag increases protection of
the driver against:

Risk of injury
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons ,you
only use seat covers that have been approved
for Mercedes-Ben zvehicles.
The seat cover smust have aspecial tear seam
for sidebags/pelvisbags. Otherwise, the side-
bag/pelvisbag cannot deploy correctly and
would fail to provide the intended protection
in the event of an accident. Appropriate seat
cover scan be obtained, for example, from a

Risk of injury
As eat belt which is not worn cor rectly, or
which has not bee nengaged in the sea tbelt
buckle cor rectly, cannot perform its intended
prote ctive function .Under certain circum-
stances, this could cause severe or even fatal
injuries in the event of an accident.
Make sure that all occupants –inparticular,
pregnan twome n–w ear their seat belt cor-
rectly at all times.
R The seat belt must fit snugly on your body
and must no tbetwisted. Therefore, you
should avoid wearing bulky clothin g(e.g. a
winter coat) .The shoulder belt section
must be routed across the cen treofy our
shoulder –onnoaccount acros syour neck
or under your arm –and pulled tight against
your uppe rbody. The lap belt must always
pass across your lap as low down as possi-
ble, i.e. over your hip join ts–n ot across
your abdomen. If necessary ,push down the
belt strap slightly and then retighten it in
the roll-up direction.
R Do not route the belt strap across sharp
edge sorfragil eobjects, especially if these
are located on or in your clothing, e.g. spec-
tacles, pens, keys, etc. The seat belt strap
could be damaged and tear in an accident,
and you or other vehicl eoccupants could
be injured.
R Onl yone person should use each sea tbelt
at any one time. Children must never travel
sittin gont he lap of other occupan ts.It
would not be possible to restrain the child
in the event of asudden change in direc-
tion, braking or an accident .This could
result in sever eoreven fata linjuries to the
child and othe roccupants.
R Persons les sthan 1.50 mtall cannot wear
the seat belts correctly. For this reason,
secure persons less than 1.50 mtall in spe-
cially designed, suitable restraint systems. 40

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
Seat-belt extender
:is extended when the
respective door is closed and the key is

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
buckle.
R the belt tongue is not engaged in the seat
belt buckle within 60 seconds. Occupant safety
