Introduction to the restraint system
The restraint system can reduce the risk of vehi- cle occupant scom ingi ntoc ontac twithp artsof
th ev ehicle's interio rintheevent of an accident.
The restrain tsystem can also reduce th eforces
to whic hvehicl eoccupant sare subjecte dduring
an accident.
The restrain tsystem includes the:
R seat belt system
R airbags
R child restrain tsystem
R child seat securin gsystem
The component softherestrain tsystem wor kin
conjunction wit heacho ther.T hey can only offer
protection if all vehicl eoccupant salways:
R have th eseat belt correctl yfastened
(Y page 33)
R have th eseat and head restrain tadjusted
properly (Y page 67)
As th edriver, you must also mak esuret hatthe
steering whee lisalso adjusted properly.
Observ ethe information on th ecorrect driver's
seat position (Y page 67).
In addition ,you must mak esuret ha tthe airbags
can inflat eproperly if they are deployed
(Y page 36).

WARNING
If th erestraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly,f or example. There is an
increased risk of injury ,possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as wellas
electronic components or their software.
If it is necessary to adjust the vehicl etoaccom-
modate aperso nwith disabilities, contact a
qualified specialist workshop. Mercedes-Benz
recommends that you use aMercedes-Benz
Service Centre for this. Restraint system warnin

regular interval swhile the engine is running.
Therefore, malfunctions can be detected in
goo dtime.
The 6 restraint system warning lamp on the
instrument cluster lights up when the ignition is switched on. It goe soutno later than afew sec-
onds afte rthe vehicl eisstarted. The compo-
nents of the restraint system are in operational
readiness.

WARNING
If the restra ints ystem is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This may affect
the seat beltt ensioner or airbag, for example.
This poses an increased risk of injury or even

Introduction The installation location of an airbag is identified
by the AIRBA Gsymbol.
An airbag supplements acorrectly worn seat
belt. It is not areplacement for the seat belt. The
airbag offers additional protection in corre-
sponding accident situations.
Not all airbags are deployed in an accident .The
different airbag systems work independently of
each other (Y page 37).
However, no system availabl etoday can com-
pletely eliminate injuries and fatalities.
It is also not possible to completely rule out a
risk of injury caused by an airbag due to the
speed at which the airbag must be deployed.
Important safety notes G
WARNING
If you deviate from the correct seat position,
the airbag canno tperform its intended pro-
tective function and can even caus eaddi-
tional injurie swhen deployed. There is an
increased risk of serious or even fatal injuries. In order to avoid such risks, always ensure
that all vehicle occupants:
R fasten their seatbelts correctly, including
pregnant women
R are seated correctly and maintain the fur-
thest possible distance from the airbags
R observe the following notes
Alway sensure that there are no objects loca-
ted betwee nthe airbag and the vehicle occu-
pant.
R Adjust the seats properl ybefore beginning
yourj ourney. Alwaysm ake sure that the seat
is in an almostu pright position. The head
restraint must be as close as possible to the
back of yourh ead.
R Move the driver's and front-passenger seats
as far back as possible. The driver's seat posi- tion must allow the vehicle to be driven safely.
R Hold the steering wheel only by the rim. This
allows the airbag to be fullyd eployed.
R Alwaysl eana gainst the backrest whiled riv-
ing. Do not leanf orwards. You may otherwise
be in the deployment area of the airbag.
R Alwaysk eep yourf eet in the footwell in front
of the seat. Do not put yourf eet on the dash-
board,f or example .Your feet may otherwise
be in the deployment area of the airbag.
R Alwayss ecure persons less than 1.50 mtall in
suitable restraint systems .Uptothish eight,
th es eat belt canno tbeworn correctly.
If ac hild is travelling in your vehicle, also
observe th efollowin gnotes:
R Always secure childre nunde rtwelve years of
age and less than 1.50 mtall in suitable child
restraint systems.
R Child restraint systems shoul dpreferabl ybe

Objects in the vehicle interior may prevent
the airba gfrom functioning correctly. Before
starting your journey and to avoid risks resulting from the speed of the airbag as it deploys, make
sure that:
R there are no people, animals or objects
between the vehicle occupant sand an airbag
R no accessories, such as cup holders, are
attached to the vehicle within the deployment
area of an airbag, e.g. to the steerin gwheel or
doors
R no heavy, sharp-edged or fragile objects are in
the pockets of your clothing. Store such
objects in asuitable place. G
WARNING
If you modify an airbag cove roraffix objects
such as stickers to it, the airbag can no longer function correctly. There is an increased risk
of injury.
Never modify an airbag cover or affix objects
to it.
Fron tairbags !
Do not place heavy objects on the front-
passenger seat. This could cause the system
to identif ythe seat as being occupied. In the
event of an accident, the restraint systems on the front-passenger side may be triggered
and have to be replaced. Driver's airbag

Operation
During th
efirst stage of acollision, the restraint
system contro lunite valuate simportant physi-
cal data relating to vehicl edeceleratio noraccel-
eration, such as:
R duration
R direction
R intensity
Based on the evaluation of thi sdata, the
restraint system contro lunitt riggers the seat
belt tensioners in the event of ahead-o norrear
collision.
As eatb eltt ensioner can be triggered onl yif:
R the ignition is switched on
R the components of the restraint system are
operational .You can find furthe rinformation
under: "Restraint system warning lamp"
(Y page 31)
R the sea tbeltb uckle tongue ha sengaged in
the belt buckle of the respectiv efront seat
The sea tbeltt ensioners in the rea rcompart-
ment ar etriggered independentl yofthe lock
status of the sea tbelts.
If the restraint system contro lunitd etects a
high-severity accident, in certain head-on colli-
sions, additional components of the restraint
system ar edeployed independentl yofeach
other:
R driver's airbag
R front-passenge rfront airbag
Depending on the perso ninthe front-passenger
seat, the front-passenge rfront airba giseither
disabled or enabled .The front-passenge rfront
airba gcan be deployed in an accident onl yifthe
PASSENGER AIR BAG OFF indicator lamp is off.
Observe the informatio nonthe PASSENGER AIR
BAG OFF indicator lamp (Y page 32).

ris kofi njuries. The driver's airba gisfully

The activatio nthreshold for the sea tbeltt en-
sioners and airbags is determine dbased on the
evaluation of the vehicle's rate of deceleration
or acceleratio natvarious points in the vehicle.
Thi sp roces sispre-emptive in nature. The trig-
gering/deployment proces sshoul dtake place
in good time at the start of the collision. Th
er ate of vehicle deceleration or acceleration
and the direction of the force are essentially
determined by:
R the distribution of forces during the collision
R the collision angle
R the deformation characteristics of the vehicle
R the characteristics of the object with which
the vehicle has collided
Factors that can be seen and measured only
after acollision has occurred do not play adeci-
sive role in the deployment of an airbag. Nor do
they provide an indication of airbag deployment.
The vehicle may be deformed significantly with-
out an airbag being deployed. This is the case if only parts that are relatively easily deformed are
affected and the rate of deceleration is not high. Conversely, an airbag may be deployed even
though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as aresult.
If the restraint system control unit detect saside
impact or if the vehicle overturns, the applicable components of the restraint system are activa-
ted independently of each other depending on
the apparent type of accident.
R Fronts eat belt tensioners, if the system
determines that deployment can offer addi-
tional protection for the vehicle occupant sin
