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
Occupant safetySafety

the centre of the driver's airba
gcover as
possible.
R move the fr ont-passenge rseatasf ar back
as possible. Thi sisespecially important if
yo uh aves ecure dac hild in achild restraint
syste mont he front-passenger seat.
R vehicle occupants –inparticular ,children
–m ust not lean their heads into the area of
the window in which the sidebag/window-
bag is deployed.
R rearward-facing child restraint systems
must not be fit tedtot he front-passenger
seat unless the front-passenger airbag has
been disabled. On the front-passenger
seat, the front-passenger airbag is disabled
if ac hild rest raint system with atrans-
ponde rfor automatic child seat recognition
is fit tedtot he front-passenger seat in a
vehicle equipped with automatic chil dseat
recognition. The 4PASSENGE RAIRBAG
OF Findicator lamp must be continuously
lit.
If the front-passenger sea tofyour vehicle
does not have automatic child seat recog-
nition ,oryour rearward-facing child
rest raint system does not have automatic
child seat recognition, children must be
secured in achild rest raint system on a
suitable seat in the rear. If you secure a
forward-facing child restraint system to the
front-passenger seat, you must move the
front-passenger seat as far back as possi-
ble.
R make sure there are no heavy or sharp-
edged objects in the pockets of clothing.
R do not lean forwards, e.g. over the cover of
the driver's/front-passenger airbag, partic-
ularly when the vehicle is in motion.
R do not put your feet on the dashboard.
R only hold the steerin gwheel on the outside.
This allow sthe airbag to be fully deployed.
You coul dbeinjured if the airbag is
deploye dand you are holding the inside of
the steerin gwheel. R
do not lean on the doors from insid ethe
vehicle.
R make sur ethat 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, for example,
coat hangers, on the grab handles or coat
hooks.
R do not atta chaccessories, 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 steerin gwheel boss
R kneebag cover below the steerin gcolumn
R front-passenger airbag cover
R outer side of seat bolsters G
WAR
NING
As mall amo untofp owder is released when

cause short-term breathing difficulties in peo-
ple with asthma or other respirator yprob-
lems.
In order to prevent bre athing difficulties ,you
should leave the vehicle as soon as it is safe
to do so. You can also open the window to
allow fresh air to enter the interior .The pow-
der does not constitute ahealth hazar dand

R Persons les sthan 1. 50mt all cannot wear
the seat belts correctly. For this reason,
secure persons less than 1.5 0mtall in spe-
cially designed, suitable restraint systems.
R Children less than 1.50 mtall or under 12
years of age cannot wear the seat belts
properly. Therefore, they should always be
secured in asuitable child restraint system
on asuitable vehicle seat. You can find
more information under "Children in the
vehicle" in the "Safety" section of the Own-
er's Manual. Follow the manufac turer's
installatio ninstructions whe nfitting achild
rest raint system.
R Do not secure any objects with aseat belt
if the seat belt is also being used by one of
the vehicle's occupants. G
WAR
NING
The seat belt doe snot offer the intended level
of protection unless the back rest is almost
ver tica l. Under certain circumstances, this
could cause severe or even fatal injuries in the
event of an accident.
Befor estarting ajourney, mak esure that the
seat is properly adjusted and that the back-
rest is almost vertical. G
WARNING
Ad irtyord amaged seat belt or aseat belt that
has been subjected to aload in an accident
or which has been modified no longer offers
the intended level of protection. Un dercertain
cir cumstances, this could caus esever eor
even fatal injuries in the even tofanaccident.
For thi sreason, check regularly that the seat
belts are not damaged or dirty.
Alway shaved am aged sea tbelts or seat belts
that have been subjected to aload in an acci-
dent replaced at aqualified specialist work-
shop. Consult aqualified specialist workshop
which has the necessary specialist knowledge
and tools to carry out the work required.
Mercedes -Benz recommends that you use a Mercedes-Benz Ser
vice Centre for thi spur-
pose.
For safety reasons, Mercedes -Benz recom-
mends that you only use seat belts which have
been approved by Mercedes-Benz for your
vehicle.

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. Children in the vehicle
Child restraint systems
Important safety notes G
WARNING
To reduce the risk of serious or even fatal
injury to the child in the event of asudden
change in direction, braking or an accident:
R children less than 1.50 mtall and under
twelve years of age must always be secured
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 secure children less than 1.50 mtall
or under twelv eyears of age on th efront-
passenger seat .Exception: the vehicl eis
equipped with automatic child sea trecog-
nition on the front-passenger seat and the
child is secured in achild rest raint system
with transponders for automatic child seat
recognition.
R if you secure aforward-facing child
rest raint system to the front-passenger
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 would not 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 sudde nchanges of direction. The
chil dcould be seriously or even fatally injured.
For this reason, when fit ting achild rest raint
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 cover swith genuine Mercedes-Benz
covers.
We recommend the use of child restraint sys-
tems which have been approved for
Mercedes-Benz vehicles.
If ac hild is travellin ginyour vehicle, secure
the child using achild restraint system which
is appropriate to the size, age and weight of
the chil dand recommende dfor Mercedes-
Ben zvehicles. You should preferabl yfit the
restraint system to asuitable rear seat. Make
sure that the child is secured in achild
restraint system thr oughout the trip.
Mercedes-Ben zrecommends that you only
use the child restraint system slisted at
(Y page 58).
You can obtain further information about the
correct child restrain tsystem from any
Mercedes-Benz Service Centre.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems. 50
