SRS (Supplementa
lRestraint System)
Introduction SRS consist
sof:
R theS RS warning lamp6
R airbags
R the airbag control unit with crash sensors
R belt tensio ners forthe front seat belts and
the outer seat belts in the rear
R belt force limiters
SRS reduce sthe risk of occupants coming
int oc ontact with the vehicle' sinterior in the
event of an accident. It can also reduce the
forces to which occupant sare subjecte ddur-
ing an accident.
SRS warning lamp G
WARNING
If SRS is malfunctioning, individual systems
may be triggered unintentionally or might 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 when the ignition is switched on.
R the engine is running and the 6SRS
warning lamp does not go out after afew
seconds.
R the engine is running and the 6SRS
warning lamp lights up again.
In this case, have SRS checked immediately
at aq ualified specialist workshop.
SRS functions are checked regularly when
you switch on the ignitio nand whe nthe
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 started. Triggering of belt tensioners, belt force
limiters and airbags During the first stage of
acollision ,the airbag
con trol unit evaluates important physical
data relatin gtovehicle deceleration or accel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control unit pre-emptively triggers the
belt tensioners in the first stage.
If there is an even higher rat eofvehicle decel-
eration or acceleration in alongitudinal direc-
tion ,the front airbags ar ealso deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluates vehi-
cle deceleration or acceleration in the event
of ac ollision .Inthe first deploymen tstage,
the front airbag is filled with enoug hpropel-
lan tgas to reduce the risk of injuries. The
front airbag is fully deploye difasecond
deployment threshold is reached within afew
milliseconds.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rat eofd eceleration or acceleration of the
vehicle. This process is pre-emptive in nature.
The triggerin gprocess mus ttake place in
good time at the start of the collision.
The rate of vehicle deceleration or accelera-
tion and the direction of the force are essen-
tially determined by:
R the distribution of forces during the colli-
sion
R the collisio nangle
R the deformation characteris tics of the vehi-
cle
R the characteris tics of the object with which
the vehicle has collided
Factors which can only be seen and measured
after acollision has occurred do not play a
decisive role in the deployment of an airbag, Occupant safety
41Safety Z

R
do not lean forwards, e.g. over the cover of
the driver's/front-passenger fron tairbag,
particularly when the vehicle is in motion.
R do not put your feet on the dashboard.
R only hold the steering wheel on the outside.
This allows the airbag to be fully deployed.
You could be injured if the airbag is
deployed and you are holding the inside of
the steering wheel.
R do not lean on the doors from inside the
vehicle.
R make sure that ther eare no people ,ani-
mals or obje ctsb etween the vehicle occu-
pants and the area where the airbags are
deployed.
R do not place any objects between the seat
back rest and the door.
R do not hang any har dobjects, e.g. coat
hangers ,onthe gra bhandles or coat hooks.
R do not attac haccessories ,e.g. cup holders,
to the doors.
It is not possible to rule out arisk of injury
being caused by an airbag, due to the high
speed at which the airbag must be deployed. G
WARNING
Airbag functionality can only be assured if the
following parts are not covered and no badges
or stickers are attached to them:
R padded steering wheel boss
R kneebag cover below the steering column
R front-passenger airbag cover
R outer side of seat bolsters G
WARNING
When an airbag deploys, asmall amount of
powder is released. Th epowder may cause
short-term breathin gdifficulties to persons
sufferin gfrom asthma or other pulmonary
conditions.
In order to prevent potentia lbreathing diffi-
culties, you should leave th evehicle as soon
as it is safe to do so. You can also open the
window to allow fresh air to enter the vehicle interior
.The powder does not constitute a
healt hhazard and does not indicat ethat there
is af ire in the vehicle. G
WARNING
The airbag parts are hot after the airbag has
been deployed. Do not touch them as you
could burn yourself.
Have the airbags replaced at aqualified spe-
cialist workshop. Otherwise, occupants are
not protected by the airbags in the event of
another accident.
Airbag deployment slow sdown and restric ts
the movement of the vehicle occupant.
If the airbags are deployed ,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 airbag installation location sare identified
by th eAIRBAG symbol.
Front airbags !
Do no tplace heavy objects on the front-
passenger seat. The system may then
detec tthat the seat is occupied and if there
is an accident ,the restraint system sonthe
front-passenger side could be deployed.

deployment can offer additional protection
to that provided by the seat belt
R depending on whether the seat belt is being
used
R independently of other airbags in the vehi-

If the vehicle overturns, the fron tairbags are
generally not deployed. The fron tairbags are
deployed if the system detec tshigh vehi cle

Vehicles with au tomatic child seat recog-
nition in th efront-passenger seat: the
fr ont-passenge rairbag is only activated if the
system determines that the fron t-passenger
seat is occupied. The 4PASSENGE RAIR-
BA GO FF indi cator lamp on the centr econ-
sole does not light up (Y page 52).
If ac hild restraint system is fitted on the fr ont-
pa ssenger seat and the 4PASSENGER

properly fitted. Driver's kneebag Driver'
skneebag :deploys under the steer-
ing column. The driver's kneebag is always
deploye dalong with the driver's front airbag.
The driver's kneebag is designed to operate
together with the front airbags in frontal
impact sifcertain thresholds are exceeded.
The driver' skneebag operates bes tincon-
jun ction with correctly positioned and fas-
tened seat belts.
The driver's kneebag increases protection of
the driver against:
R knee injuries
R thigh injuries
R lower leg injuries
Sidebags G
WARNING
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat cover sthat hav ebeen approved
for Mercedes-Benz vehicles.
The seat covers must have aspecial tear seam
for sidebags. Otherwise, the sidebags cannot
deploy correctly and would fail to provide the
intended protection in the event of an acci-
dent. Appropriate seat cover scan be
obtained, for example, from aMercedes-Benz
Servic eCentre. G

protect occupants in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes:
R if BAS activates, e.g. in emergency braking
situations
R if BAS PLUS intervenes powerfull y—on
vehicles wit hDISTRONIC PLUS
R if, on vehicles with DISTRONIC PLUS, the
radar sensor system detects an imminent
dang er of collision in cer tain situations
R in critical drivin gsituations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R vehicles with the memor yfunction: the
front-passenger seat is adjusted if it is in an
unfavourable position.
R vehicles with amulticontour seat: the air
pressure in the side bolsters of the back-
rest is increased.
R if the vehicle skids ,the slidin gsunroof/
panorama sliding sunroof and the side win-
dows are closed so that only asmall gap
remains.
If th ehazardous situation passe swithout
resulting in an accident ,PRE-SAFE ®
slackens
the belt pretensioning. On vehicles with mul-
ticontour seats ,the air pressur einthe side
bolster sisreduced again. All settings made
by PRE- SAFE®

WARNING
As eat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, can notp rovide th eintended
level of protection. Under certain circumstan-
ces, this could cause severe or even fatal inju-
ries in the event of an accident.
Therefore, make sure that all occupants —in
particular ,pregnant women —wear their seat
belts cor rectly at all times.
R Th es eat belt must fit snugly on your body
and must not be twisted.Therefore, avoid
wearing bulky clothing, e.g. awinter coat.
The shoulder section of the belt must be
routed across the centre of your shoulder
—onnoa ccount acros syour nec korunder
your arm —and pulled tight against your
uppe rbody. The lap belt must always pass
across your lap as low down as possible, i.e.
over your hip join ts—n ot across your abdo-
men .Ifn ecessary, push the seat belt
slightly downwards and adjust it by pulling
it in the direction the seat belt retracts.
R Do not rout ethe seat belt strap over sharp
or fragile objec ts.P lease make sure that
such object sare not on or in your clothing,
e.g .spectacles, pens or keys etc. The seat
belt strap could become damaged and tear
durin gana ccident and you or other vehicle
occupants coul dbeinjured.
R Only one person should use each sea tbelt
at any one time. Children must never travel
sittin gont he lap of another occupan t.The
child will not be secured in the even tofan
accident ,heavy braking or sudden change
of direction .This ma yresult in the child or
other occupants being seriously or fatally
injured. 46
