Introduction The installation location of an airbag is iden-
tified by the AIRBA Gsymbol.
An airbag supplements acorrectly worn seat
belt. It is not areplacemen tfor the seat belt.
The airbag offers additional protection in
applicable accident situations.
Not all airbags are deployed in an accident.
The differen tairbag systems work independ-
ently of each other (Y page 53).
However, no system available today 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 safet ynotes G
WARNING
If you deviat efromt he correc tseat position,
the airbag cannot perform its intended pro-
tectiv efunction and can even cause addi-
tional injuries when 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 seate dcorrectly and maintain the fur-
thest possible distanc efromt he airbags
R observe the followin gnotes
Always ensure that there are no object sloca-
ted betwee nthe airbag and the vehicle occu-
pant.
R Adjust the seats properly befor ebeginning
your journey. Always make sure that the
seat is in an almost upright position. The centr
eofthe head restraint must support
the head at about eye level.
R Move the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
drive nsafely.
R Only hold the steerin gwheel on the out-
side. This allows the airbag to be fully
deployed.
R Always lean against the backrest while driv-
ing. Do not lean forwards or lean against
the door or side window. You may other-
wise be in the deploymen tarea of the air-
bags.
R Always keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard ,for example. Your feet may oth-
erwise be in the deploymen tarea of the
airbag.
R Always secur epersons less than 1.50 mtall
in suitable restraint systems .Uptothis
height ,the seat belt canno tbeworn cor-
rectly.
If ac hild is travelling in you rvehicle, also
observe th efollowing notes:
R Always secure childre nunde rtwelve years
of age and less than 1.50 mtall in suitable
child restraint systems.
R Child restraint systems should be fitte dto
th er ear seats.
R Only secure achild to th efront-pa ssenger
seat when th efront-pa ssenger fron tairbag
is disabled, and only then in arearward-
facing child restraint system. If the
PASSENGER AI RBAG OFFindicator lamp is
permanently lit ,the front-passenger front
airbag is disabled (Y page 45).
R Always observ ethe instruction sand safety

(Y page 58) and on th e"Child restraint
system on th efront-pa ssenger seat"
(Y page 67 )inaddition to th echild

Occupant safetySafety

Objects in the vehicle interior may pre-
vent the airba gfrom functioning cor-
rectly. Beforestarting 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 air-
bag.
R there are no objects between the seat, door
and B-pillar.
R no hard objects, e.g. coat hangers, are
hanging on the grab handles or coat hooks.
R no accessories, such as cup holders, are
attached to the vehicle within the deploy-
ment area of an airbag, e.g. to doors, side
windows, rear side trim or side walls.
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 cover or affix 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. G
WARNING
Sensors to control the airbags are located in
the doors. Modification sorwork not per-
formed correctly to the doors or door panel-
ling, as well as damaged doors, can lead to the function of the sensor sbeing impaired. The
airbags might therefore not function properly any more. Consequently, the airbags cannot
protec tvehicle occupant sasthey are
designed to do. This poses an increased risk
of injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door pan-
elling carried out at aqualified specialist
workshop. Front airbags
Driver's airbag
:deploys in fron tofthe
steerin gwheel. Front-passenger fron tair-
bag ;deploys in fron tofand above the glove
compartment.
When deployed, the fron tairbags offer addi-
tional head and thorax protection for the
occupant sinthe fron tseats.
Ap ermanently lit PASSENGER AIR BAG OFF
indicator lamp informs you that the front-
passenger fron tairbag is disabled
(Y page 45).
Driver's kneebag Driver's kneebag
:deploys under the steer-
ing column. The driver's kneebag is triggered
together with the fron tairbag.
The driver's kneebag offers additional thigh,
knee and lower leg protection for the occu-
pant in the driver's seat.
i The driver's kneebag is only available in
certain countries. Occupant safety

Sidebags
G
WARNING
Unsuitable seat covers may obstruct or even
prevent deployment of the airbags integrated into the seats. The airbags may then fail to
protect the vehicle occupants as intended.
Operation of the automatic child seat recog-
nition may also be impaired. There is an
increased risk of injury, possibly even fatal.
Use only seat covers which have been specif-
ically approved for the respective seat by
Mercedes-Benz. Example: Saloon
Front sidebags :and rear sidebags ;
deploy next to the outer bolster of the seat
backrest.
When deployed, the sidebag offers additional thorax protection. However, it does not pro-
tect the:
R head
R neck
R arms
In the event of aside impact, the sidebag is
deployed on the side on which the impact
occurs.
Pelvisbags G
WARNING
Unsuitable seat covers may obstruct or even
prevent deployment of the airbags integrated into the seats. The airbags may then fail to
protect the vehicle occupants as intended. Operation of the automatic child seat recog-
nition may also be impaired. There is an
increased risk of injury, possibly even fatal.
Use only seat covers which have been specif- ically approved for the respective seat by
Mercedes-Benz. Pelvisbags
:deploy next to and below the
outer seat cushions.
When activated, the pelvisbag enhances the
level of protection of the vehicle occupants
on the side of the vehicle on which the impact
occurs.
The pelvisbag is deployed on the side of the
impact.
i Pelvisbags are only available in certain
countries.
Windowbags Example: Saloon
Windowbags :are integrated into the side
of the roof frame and deploy in the area from the A-pillar to the C-pillar. 52
Occupant safetySafety

When deployed, the windowbag enhances the
level of protection for the head. However, it
does not protec tthe chest or arms.
In the event of aside impact, the windowbag
is deployed on the side on which the impact
occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, awindowbag may be deployed in
other accident situation s(Ypage 53). Deployment of belt tensioners and air-
bags
Important safety notes G
WARNING
After the airbag deploys, the airbag parts are
hot. There is arisk of injury.
Do not touch the airbag parts. Have a
deployed airbag replaced at aqualified spe-
cialist workshop as soon as possible. G
WARNING
Pyrotechnic seat belt tensioners that have
been deployed are no longer operational and
are unable to perform their intended protec-
tive function. This poses an increased risk of
injury or even fatal injury.
Therefore, have pyrotechnic belt tensioners
which have been triggered immediately
replaced at aqualified specialist workshop.
Mercedes-Benz recommends that you have
the vehicle towed to aqualified specialist
workshop after an accident .Take this into
account ,particularly if aseat belt tensioner
was triggered or an airbag was deployed.
An electric motor is used by PRE-SAFE ®
to
trigger the tightening of the seat belt in haz-
ardous situations. This procedure is reversi-
ble.
If the belt tensioners are triggered or an air-
bag is deployed, you will hear abang, and a
small amount of powder may also be released. The
6restraint system warning
lamp lights up.
Only in rare cases will the bang affect your
hearing. In general, the powder released is
not hazardous to health but may cause short- term breathin gdifficulties to persons suffer-
ing from asthma or other pulmonary condi-
tions. Provided it is safe to do so, you should
leave the vehicle immediately or open the
window in order to preven tbreathin gdifficul-
ties.
Operation During the first stage of
acollision, the
restraint system control unit evaluates impor-
tant physical data relating to vehicle deceler- ation or acceleration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the
restraint system control unit trigger sthe seat
belt tensioners in the event of ahead-on or
rear collision.
As eat belt tensioner can only be triggered if:
R the ignition is switched on
R the componentsoft he restraint system are
operational; see "Restraint system warning lamp" (Y page 45)
R the belt tongue has engaged in the belt
buckle of the respective fron tseat
The seat belt tensioners in the rear compart-
ment are triggered independently of the lock
status of the seat belts.
If the restraint system control unit detect sa
high severit yofanaccident,incertain head-
on collisions, additional componentsoft he
restraint system are deployed independently
of each another:
R Fron tairbags and driver's kneebag
R Windowbag, if the system determines that
deployment can offer additional protection
