If there is an even higherr
ate of vehicle decel-
eration or acceleratio ninalongitudinal direc-
tion ,the front airbags are also deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluate svehi-
cle deceleration or acceleration in the event
of ac ollision. In the firs tdeployment stage,
the fron tairbag is filled with enough propel-
lant gas to reduc ethe risk of injuries. The
front airbag is fully deployed if asecond
deploymen tthreshold is reached within afew
milliseconds.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration or acceleration of the
vehicle. This process is pre-emptive in nature.
The triggering process must take 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 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 may be deformed 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 rate of deceleration 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 parts such as longitudinal body
members are hit, and sufficient deceleration
occurs as aresult. i
The front belt tensioners can only be trig-
gered if the seat belt tongues on the front
seats are correctly engaged in the seat belt
buckles.
i Not all airbags are deployed in an acci-
dent. The different airbag systems work
independently of each other.
How the airbag system works is deter-
mined by the severity of the accident detec-
ted, especiallyt he vehicle deceleration or
acceleration, and the apparent type of acci-
dent:
R head-on collision
R side impact
R overturn Airbags
Important safety notes 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-
nan twome n–m ust wear their seat belt
correctly at all times and lean back against
th eb ackrest, whic hshoul dbep ositioned
as close to th evertical as possible. The
head restraint must support th eback of the
head at about eye level.
R always secure childre nless than
1.50mt all or unde r12years of age in suit-
able child restraint systems.
R all vehicle occupant smust select aseat
position that is as far away from the airbag
as possible. The driver's seat position must
allow the vehicle to be driven safely. The
driver's chest should be as far away from
the centre of the driver's airbag cover as
possible. 42

an accident, reset the NECK-PRO head
restraints/NECK-PRO luxury head restraints
on the driver's and front-passenger seats
(Y page 47). Otherwise, the additional pro-
tection will not be available in the event of
another rear-en dcollision. NECK-PRO head

WARNING
When adjusting the seat, make sure that
nobody can become trapped.
! Make sure that there are no objectsint he
footwell or behind the seats when moving
the seat back. There is arisk that the seats
and/or the objectsc ould be damaged.
PRE-SAFE ®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes:
R when BAS activates, e.g. in emergency
braking situations
R when BAS PLUS intervenes powerfully on
vehicles with DISTRONIC PLUS
R if, on vehicles with DISTRONIC PLUS, the
radar sensor system detectsani mminent
dange rofcollision in certain situations
R in critical driving situations, 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 memory function: the
front-passenger seat is adjusted if it is in an
unfavourable position.
R vehicles with amulticontour seat or active
multicontour seat: the air pressure in the
side bolsters of the seat cushion and back-
rest is increased.
R if the vehicle skids, the sliding sunroof/
panorama sliding sunroof and the side win-
dows are closed so that only asmall gap
remains.
If the hazardous situation passes without
resulting in an accident ,PRE-SAFE ®
slackens
the belt pretensioning. The air pressure in the
side bolsters on the multicontour seat/active
multicontour seat is reduced again. All set- tings made by PRE-SAFE
®
can then be
reversed.
If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
lockin gmechanism is released.

Important safety notes G
WARNING
As eat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot provide the intended
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 occupant s—in
particular, pregnan twomen —wear their seat
belts correctly at all times.
R The seat 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 across your neck or under
your arm —and pulled tight against your
uppe rbody. The lap belt must alwaysp ass
across your lap as low down as possible, i.e.
over your hip joints—n ot across your abdo-
men. If necessary, push the seat belt
slightly downwards and adjust it by pulling
it in the direction the seat belt retracts.
R Do not route the seat belt strap over sharp
or fragile objects. Please 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 48

Releasing the seat belts !
Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfil their
protective function and must be replaced.

Occupant safetySafety

Comply wit
hsafety regulation swhen dispos-
ing of belt tensioners. Any Mercedes-Benz
Service Centre can provide details of these
regulations.
! If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
The seat belts are fitted with belt tensioners.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrects eat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with abelt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupant is
reduced.
The belt force limiters for the front seats are
synchronised with the front airbags, which
take on apart of the deceleration force. This
results in the force exerted on the occupant
being distributed over agreater area.
The belt tensioners can only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 41).
R the belt tongue is engaged in the buckle on
each of the three-point seat belts in front.
R
The belt tensioners on the seats in the rear
compartmenta re triggeredindependently of
the lock status of the seat belts.
The beltt ensioners are triggered depending
on the type and severit yofanaccident:
R if, in the event of ahead-on or rear-en dcol-
lision the vehicle decelerates or acceler- ates rapidly in
alongitudinal direction dur-
ing the initial stages of the impact
R if, in the event of aside impact, on the side
opposite the impact the vehicle deceler-
ates or accelerates rapidly in alateral direc-
tion
R in certain situation swhere the vehicle over-
turn sand the system determines that it can
provide additional protection
If the airbags are deployed, you will hear a
bang, and asmall amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The 6SRS warning lamp

Important safet ynotes G
WARNING
To reduce the risk of serious or even fatal
injur ytot he child in the event of asudden
change in direction, brakin goranaccident:
R children less than 1.5 0mtall and under
twelve years of age must alway sbesecured
in special child restraint systems on asuit-
able vehicle seat. This is necessary
because the seat belts are not designed for
children.
R Do not drive with achild secured in arear-
ward-facin gchild restraint system on the
front-passenger seat. Exception: if the vehi-
cle is equipped with automatic child seat
recognition on the front-passenger seat
and the child is secured in achild restraint
system with transponder sfor automatic
child seat recognition
R if you secure aforward-facing child
restraint system to the front-passenger 52

seat, you must move the front-passenger
seat as far back as possible.
R children must never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of asudden
change of direction, heavy braking or an
accident, it wouldn ot be possible to
restrain the child. The child could be thrown
against parts of the vehicle interior and be
seriously or even fatally injured. G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to as uitable vehicle seat. The child cannot be
restrained in the event of an accident, heavy
braking or sudden changes of direction. The
child could be seriously or even fatally injured.
For this reason, when fitting achild restraint
system, observe the manufacturer's installa-
tion instructions and the correct use of the
child restraint system.
Child restraint systems should be fitted to the
rear seats. Children are generally better pro-
tected there.
The entire base of the child restraint system
must always rest on the seat cushion. There-
fore, never place objects, e.g. acushion,
under the child restraint system.
Only use child restraint systems with the orig-
inal cover designed for them. Only replace
damaged covers with genuine Mercedes-Benz
covers.
We recommend the use of child restraint sys-
tems which have been approved for
Mercedes-Benz vehicles. G
WARNING
Do not leave children unsupervised in the
vehicle, even if they are secured in achild
restraint system. They could injure them-
selves on parts of the vehicle. They could also
be seriously or even fatally injured by pro-
longed exposure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. Parts of the child restraint sys- tem could heat up and the child could burn
herself/himself on them.
If
ac hild opens adoor, the child or other per-
sons could be injured as aresult. They could
get out and injure themselves or be injured by
ap assing vehicle.
Observe the general notes on the HOLD func-
tion, which can be found under the same key-
word. G
WARNING
Unsecured or incorrectly positioned loads
increase the risk of injury for children and all
other occupants in the event of:
R an accident
R sudden braking
R as udden change of direction
Do not transport heavy or hard objects in the
vehicle interior unless they are secured. You
will find further information under "Loading
guidelines" in the index.
If ac hild is travelling in your vehicle, secure
the child using achild restraint system which
is recommended for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
Ideallyt he child restraint system should be
installed on asuitabler ear seat. Make sure
that the child is secured for the trip.
Mercedes-Benz recommends that you use
the listed child restraint systems
(Y page 60). You can obtain further infor-
mation aboutt he correct child restraint sys-
tem from any Mercedes-Ben zService Centre.

more than 22 kg, secure the child restraint
system with the vehicle seat belt as well. In
addition, when fittingac hild restraint system,
be sure to observe the manufacturer's instal-
lation instructions and the instructions for
correct use of the child restraint system. G
WARNING
Please note that if child restraint systems, or
their retaining systems, are damaged or sub-
jected to aload in an accident, they may not
be able to provide their protective function.
This could result in serious or even fatal inju-
ries to the secured child in the event of an
accident, heavy braking or asudden change
in direction.
For this reason, have child restraint systems
and their anchorages which have been dam-
aged or subjected to aload in an accident
checked immediately at aqualified specialist
workshop. When installing the ISOFIXc
