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

inte rvenes:
R in emergenc ybraking situations ,e.g. if BAS
is activated or for vehicles with DISTRONIC
PLUS, BAS PLUS intervenes powerfully
R if the radar senso rsystem detects an immi-
nent dange rofcollision in cer tain situa-
tions (on vehicles with DISTRONIC PLUS)
R in critical drivin gsituations, e.g. when phys-
ical limits are exceed and the vehicle under-
steers or oversteers severely
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the fron tseat belts are pre- tensio ned.
R vehicles with the memory fun ction :it
adjust sthe front-pas senger seat if it is in
an unfavourable position.
R if th evehicle skids, th eslidin gsunroof/
panoram aslidin gsunroof and th eside win-
dows are closed so tha tonly asmall gap
remains.
If th ehazardous situatio npasses without
resulting in an accident ,PRE-SAFE ®
slackens
the belt pretensioning. All settings made by
PRE-SAFE ®
can then be reversed.
If the seat belts are not released:
X Move the backrest or seat back sligh tly, but
only when the vehicle is stationary.
The belt pretensionin gisreduced and the
locking mechanis misreleased. G
WARNING
When adjusting the seat, mak esure that
nobody can become trapped.
! Make sure that there are no objects in the
footwell or behind the seats when moving
the seat back. There is arisk that the seats
and/or the objects could be damaged.

adjustment" section (Y page 48). Seat belts
Important safety notes Seat belts are the most effective means of
restraining the movemen

pant sint he even tofana ccident. This
reduce sthe risk of vehicle occupan ts coming
into contact with parts of the vehicl einterior. G
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
in the event of asudden change in direc-
tion, braking or an accident .This could 46

The seat-belt adjustment will apply acertain
tightening force if any slack is detected
between the occupant and the seat belt. Do
not hold on to the seat belt tightly while it is
adjusting. You can switc hthe seat-belt
adjustment on and off in the on-boar dcom-
puter (Y page 251).
The seat-belt adjustment is an integra lpart of
the PRE-SAFE ®

Belt warning for driver and front
passenger The
7 seat belt warning lam pint he instru-
men tcluster is areminder for all occupants
to fasten their seat belts. It may light up con-
tinuously or flash. In addition ,there ma ybea
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the front passenge rhave fastened their seat
belt.
For certain countries only: regardless of
whethe rthe driver or the front passenger
hav efastened their seat belts, the 7seat
belt warning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the front passenger have fas-
tened their seat belts.
