i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviation sare possible .Please
not ethat your vehicle ma ynot be equipped
with all featur es described. This also
applies to safety-releva ntsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 24).Occupant safety
Important safet
ynotes
Seat belts, together wit hthe Supp lemental
Restrain tSyste m–S RS (Y page 41), are
complementary, co-ordinated restrain tsys-
tems. They reduce the risk of injur yinspe-
cific, pre-defined types of accident situations
and thereby increase occupant safety .How-
ever ,seat belts and airbags generally do not
protec tagainst objec tspenetratin gthe vehi-
cle from the outside.
To ensur ethat the restraint system scan
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 92).
R the seat belt has been fastened properly
(Y page 47).
R the airbags can inflate unrestricted if
deplo yed (Y page42).
R the steering whee lisadjusted properly
(Y page 92).
R the restraint systems have not been modi-
fied.
i An airba gincrease sthe protection of
vehicle occupants wearing aseat belt. As
such, they are only an additional restraint
system which complemen ts,b ut does not
replace, the seat belt. All vehicle occupants must wear their seat belt correctly at all
times, even if the vehicle is equipped with
airbags. The airbags are not deplo yed inall
types of accidents. For example, if the pro-
tective capacity of correctly fastened seat
belts is not increased by deplo yingthe air-
bags, the airbags will not deploy. Airbag
deploymen tonly provides incre asedpro-
tection if th eseatb eltisw ornc orrect ly
because:
R the sea tbelt helps to keep the vehicle
occupan tinthe best position in relation
to the airbag.
R in ah ead-on collision ,for example, the
seat belt prevents the vehicle occupant
from being propelled towards the point
of impact .Itcan thus reduce the risk of
injury.
In accidents in which an airbag is deployed,
it provides increased protection only if the
seat belt is worn correctly. G
WARNING
If service work is not carried out correctly, the
operating safety of your vehicle may be affec-
ted. This could cause you to lose control of
your vehicle and cause an accident. More-
over, the safety systems may no longer be
able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop. The workshop
must have the necessary specialist knowl-
edge and tools to carr yout the work required.
Mercedes-Ben zrecom mends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop. 40

WARNING
Modifications to or work performe dincor-
rectly on the following parts can result in the
restraint systems not functioning as intended:
R the restraint system, consisting of seat
belts and thei ranchorage points, bel tten-
sioners, belt for celimiter sand airbags
R the wiring
R networked electronic systems
Airbags and belt tensioners could fail to
deploy or be trigge redinana ccident despite
the deceleration force being sufficient to trig-
ger the systems, or could be triggered unin-
tentionally. For this reason, never make any
modifications to the restrain tsystems.
Therefore, you must not tamper with elec-
tronic components or their software. SRS (Supplemen
talRestraint System)
Introduction SRS consists of:
R
the 6 SRS warning lamp
R airbags
R airba gcontrol unit (with crash sensors)
R belt tensioner sfor the front seat belts and
the outer seat belts in the rear
R belt force limiters
SRS reduces the risk of occupan ts 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 warnin glamp SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. 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
WARNING
If SRS is malfunctioning, individual systems
may be activated unintentionally or may not
be triggered in the even tofanaccident 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 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 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 tensioner sinthe first stage.
i The front belt tensioner scan only be trig-
gered if the seat belt tongues on the front
seats are correctly engaged in the seat belt
buckles.
If there is an even higher rate of vehicle 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 Occupant safety
41Safety Z

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 deployed if asecond
deployment threshold is exceeded within a
few 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.
i Airbags are not deployed in all types of
accidents. Also, not all airbags are
deployed together in an accident .The dif-
ferent airbag system swork independently
of each other.
How the airbag system work sisdeter-
mined by the severity of the collision detec-
ted, especially the vehicle deceleration or
acceleration, and the apparent type of acci-
dent:
R head-on collision
R side impact
R overturn
The rat eofvehicle 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 collision angle
R the deformation characteristics of the vehi-
cle
R the characteristics 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,
nor do they provide an indication of airbag
deployment.
The vehicle ma ybedeformed significantly,
e.g. the bonnet or the wing, without an airbag
being deployed. This is the case if only parts
which are relatively easily deformed are affec- ted and the rat
eofdeceleration is not high.
Conversely, airbags may be deployed even
though the vehicle suffers only minor defor-
mation. This is the case if, for example, very
rigid vehicle part ssuch as longitudinal body
members are hit, and sufficient deceleration
occurs 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 airbag installation locations are identified
by the AIRBA Gsymbol. G
WARNING
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 positioned
as close to the vertical as possible. The
head restraint must support the back 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 42

deployed.
Front-passenger airbag ;is only activated if
the system determines that the front-
passenger seat is occupied. The 4
PASSENGER AIRBA GOFF indicato rlamp on
the centre console is not lit (Y page 52).
This means that achild restraint system with- out automatic chil
dseat recognition has been
fitted or that achild restraint system with
automatic chil dseat recognition is incorrectly
fitted.

WARNING
As eat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, can notp erform its intended
protectiv efunction. Under certain circum-
stances, this could cause severe or even fatal
injuries in the event of an accident.
Make sure that all occupant s–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, avoid
wearing bulky clothing, e.g. awinter coat.
The shoulder belt section must be routed
across the centre of your shoulder –onno
account across your neck or under your
arm –and pulled tight against your upper
body .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 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
