Introduction to the restraint system
The restraint system can reduce the risk of
vehicle occupants comin gintoc ontact with
parts of the vehicle' sinterior in the even tof
an accident. The restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system includes the:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securin gsystem
The components of the restraint system work
in conjunction with each other .They can only
offer protection if all vehicle occupants
always:
R have the seat belt correctly fastened
(Y page 47)
R have the seat and head restraint adjusted
properly (Y page 123)
As the driver, you must also make sure that
the steering wheel is also adjusted properly.
Observ ethe information on the correct driv-
er's seat position (Y page 122).
In addition ,you must make sure that the air-
bags can inflat eproperly if they are deployed
(Y page 50).
An airbag supplement sacorrectly worn seat
belt. As an additional safet ydevice, the airbag
increases the level of protection for vehicle
occupants in the even tofanaccident. The
airbags are not deployed, for example, in the even tofana ccidentinwhich sufficient pro-
tection is offered by the seat belt. In addition,
only thos eairbags, which in the applicable
acciden tsituation soffer additional protec-
tion ,are deployed in the even tofanaccident.
However ,the seat belt and airbag generally
do not protect against objects penetrating
the vehicle from the outside.
Information on how the restraint system
operates can be found under "Deploymen tof
belt tensioner sand airbags" (Y page 53).44

PASSENGERA
IR BAG OFF indicator lamp :
shows you whether the front-passenger front airbag is disabled.
X Turn the key to position 1or 2in the ignition
lock or, on vehicles with KEYLESS-GO,
press the Start/Stop button once or twice. The system carries out aself-diagnosis.
The PASSENGERA IR BAG OFF indicator lamp
must light up for approximately six seconds.
If, after the system self-test, the
PASSENGER AIR BAG OFF indicator lamp:
R lights up ,the front-passenger fronta irbag
is disabled. It will then not be deployed in
the event of an accident.
R is not lit,t he sensor system did not detect
ac hild restraint system with transponder
for automatic child seat recognition. If, in
the case of an accident ,all deployment cri-
teria are met, the front-passenger fronta ir-
bag is deployed. G
WARNING
Electronic devices on the front-passenger
seat can affect the function of the automatic
child seat recognition, for example:
R laptop
R mobile phone
R transponder cards such as ski passes or
access passes
The front-passenger fronta irbag could deploy
unintentionally or not function as intended
during an accident .This poses an increased
risk of injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat. Be aware of the status of the front-passenger fronta irbag both before and
during the journey. Child restraint system on the front-
passenger seat
General notes Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you install achild restraint system on a
rear seat.
Vehicles with automatic child seat recogni-
tion on the front-passenger seat: if it is abso- lutely necessary to fit achild restraint system
to the front-passenger seat, alway sobserve
the information on "Automatic child seat rec-
ognition on the front-passenger seat"
(Y page 65).
You can thus avoid the risks that could arise
as aresult of:
R ac hild restraint system that is not detected
by the automatic child seat recognition
sensor system
R the unintentional disabling of the front-
passenger fronta irbag
R the unsuitable positionin gofthe child
restraint system, e.g. too close to the dash-
board Please observe the warning notice on the
front-passenger sun visor; see the illustra-
tion.

off, the front-passenger front airbag can
deploy in the event of an accident .The child
could be struck by the airbag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air-
bag has been disabled. The PASSENGER AIR- BAG OFF indicator lamp must be lit.
NEVERu searearward facing child restraint
on aseat protected by an ACTIVE AIRBAGin
front of it; DEATH or SERIOUS INJURY to the
CHILD can occur.
Vehicles without automatic child seat
recognition on the front-passenger seat If the front-passenger seat of your vehicle is
not equipped with automatic child seat rec-
ognition
,this is indicated by aspecial sticker.
The sticker is affixed to the side of the dash-
board on the front-passenger side. The
sticker is visible when you open the front-
passenger door.
If you turn the key to position 2in the ignition
lock, the PASSENGER AIR BAG OFF indicator lamp lights up briefly. It has no function, how-ever, and does not indicate that the front-
passenger seat is equipped with automatic
child seat recognition.
Always fit the rearward-facing restraint sys-
tem to asuitable rear seat in this case
(Y page 70).
Observe the following information under
"Rearward-facing child restraint system" and
"Forward-facing child restraint system" as
well as information on the suitable position- ing of the child restraint system
(Y
page 70).
Rearward-facing child restraint system Warning symbol for
arearward-facing child
restraint system.
If it is absolutely necessary to fit arearward-
facing child restraint system to the front-
passenger seat, always make sure that the
front-passenger front airbag is disabled. Only if the PASSENGER AIR BAG OFF indicator
lamp is lit continuously (Y page 45) is the
front-passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 70) in addition to the child restraint
system manufacturer' sinstallation and oper-
ating instructions.
Forward-facing child restraint system If it is absolutely necessary to fit
aforward-
facing child restraint system to the front-
passenger seat, always move the front-
passenger seat as far back as possible. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the child
restraint system must, as far as possible, lie
flat against the backrest of the front-
passenger seat. The child restraint system
must not touch the roof or be put under strain by the head restraint .Adjust the angle of the
seat backrest and the head restraint position accordingly. Always make sure that the shoul-
der belt strap is correctly routed from the 68
