Introduction to the restraint system
The restraint system can reduce the risk of vehi-
cle occupants coming into contact with parts of
the vehicle's interior in the event of an accident. Furthermore, the restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system includes:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing system The various components of the restraint system
work complementary to one another. They can
only perform their intended protective function
if all vehicle occupants:
R have correctly fastened their seat belt
(Y page 45)
R have correctly adjusted their seat and head
restraint (Y page 100).
As the driver, you must also ensure that the
steering wheel is correctly adjusted. Observe
the information relating to the correct driver's
seat position (Y page 100).
Additionally, you must ensure that an airbag can
deploy freely (Y page 48).
The airbag is supplementary to a correctly fas-
tened seat belt. As an additional safety device,
the airbag increases the level of protection for
vehicle occupants in the event of an accident. If the protection provided by the seat belt is suf-
ficient, the airbags do not deploy. Furthermore,
in the event of an accident, only airbags which
provide greater protection in the given accident situation deploy. However, seat belts and air-
bags generally do not protect against objects
penetrating the vehicle from the outside.
Information on how the restraint system oper-
ates can be found in "Deployment of the seat
belt tensioner and airbags" (Y page 56).
See "Children in the vehicle" for information on
infants and children traveling with you in the
vehicle restraint systems for infants and chil-
dren(Y page 59). Important safety notes
G
WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If the vehicle needs to be adapted to accommo- date a person with disabilities, please contact a
specialist workshop. 42
Occupant safetySafety

An airbag supplements a correctly fastened seat
belt. It is not a substitute for seat belts. The air-
bag provides additional protection in the corre-
sponding accident situations.
Not all airbags are deployed in an accident. The
various airbag systems work independently of
one another (Y page 56).
However, no system available today can com-
pletely eliminate injuries and fatalities.
Due to the required speed of the airbag after
deployment, it is also not possible to entirely
rule out the risk of injuries caused by the airbag.
Important safety notes G
WARNING
If you deviate from the correct seat position,
the airbag cannot perform its intended pro-
tective function 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 seated correctly and maintain the fur-
thest possible distance from the airbags
R observe the following notes
Always ensure that there are no objects loca-
ted between the airbag and the vehicle occu-
pant.
R Adjust the seats properly before beginning
your journey. Always make sure that the seat
is in an almost upright position. The centre of
the 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 posi- tion must allow the vehicle to be driven safely.
R Only hold the steering wheel on the outside.
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 otherwise be in
the deployment area of the airbags.
R Always keep your feet in the footwell in front
of the seat. Do not put your feet on the dash- board, for example. Your feet may otherwise
be in the deployment area of the airbag.
R Always secure persons less than 1.50 mtall in
suitable restraint systems. Up to this height,
the seat belt cannot be worn correctly.
If a child is travelling in your vehicle, also
observe the following notes:
R Always secure children under twelve years of
age and less than 1.50 mtall in suitable child
restraint systems.
R Child restraint systems should be fitted to the
rear seats.
R Only secure a child to the front-passenger
seat when the front-passenger front airbag is
disabled, and only then in a rearward-facing
child restraint system. If the PASSENGER AIR BAG OFF indicator lamp is permanently lit, the
front-passenger front airbag is disabled
(Y page 43).
R Always observe the instructions and safety
notes on the "Automatic front-passenger
front airbag deactivation system"
(Y page 50) and on "Children in the vehicle"
(Y page 59) in addition to the manufactur-
er's operating and installation instructions for the child restraint system.
Objects in the vehicle interior may prevent
the airbag from functioning correctly. Before
starting 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 occupants and an airbag.
R there are no objects between the seat, door
and B-pillar.
R no hard objects, e.g. coat hangers, are hang-
ing on the grab handles or coat hooks.
R no accessories, such as cup holders, are
attached to the vehicle within the deployment
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 a suitable 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. 48
Occupant safetySafety

Never modify an airbag cover or affix objects
to it. G
WARNING
Sensors to control the airbags are located in
the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ling, as well as damaged doors, can lead to the function of the sensors being impaired. The
airbags might therefore not function properly any more. Consequently, the airbags cannot
protect vehicle occupants as they 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 a qualified specialist
workshop.
Front airbags !
Do not place heavy objects on the front-
passenger seat. This could cause the system
to identify the seat as being occupied. In the
event of an accident, the restraint systems on
the front-passenger side may be triggered
and have to be replaced. Driver's airbag
:deploys in front of the steer-
ing wheel. Front-passenger front airbag ;
deploys in front of and above the glove com-
partment.
When deployed, the front airbags offer addi-
tional head and thorax protection for the occu-
pants in the front seats.
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the front-
passenger front airbag (Y page 43).The front-passenger front airbag will deploy only
if:
R the automatic front-passenger front airbag
deactivation system has detected that the
front-passenger seat is occupied
(Y page 50). The PASSENGER AIR BAG OFF
indicator lamp is not lit (Y page 51)
R the restraint system control unit predicts a
high accident severity
Driver's kneebag Driver's knee airbag
:deploys under the steer-
ing column. The driver's knee airbag is triggered
together with the front airbags.
The driver's knee airbag offers additional thigh,
knee and lower leg protection for the occupant
in the driver's seat.
i The driver's knee airbag is available only in
certain countries.
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 co-driver's front
airbag deactivation system 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. Occupant safety

Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
R the hazard lamps are switched on
R the emergency lighting is switched on
R the vehicle doors are unlocked
R the front side windows are lowered
R vehicles with the memory function: the elec-
trically adjustable steering wheel is raised
R the engine is switched off and the fuel supply
is cut off
R vehicles with the Mercedes-Benz emergency
call system: automatic emergency call Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
a child restraint system on a rear seat. Children are generally better protected there.
If a child younger than twelve years old and
under 1.50 min height is travelling in the vehi-
cle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
R be sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions.
R be sure to observe the instructions and safety
notes on the automatic front-passenger front airbag deactivation system (Y page 50). G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If persons (particularly children) are exposed
to heat or cold for a prolonged period, there is a risk of serious or even fatal injuries. Never
leave persons (particularly children) unatten-
ded in the vehicle. G
WARNING
If the child restraint system is placed in direct sunlight, the parts could become very hot.
Children could be suffer burns by touching
these parts, in particular on the metallic parts
of the child restraint system. There is a risk of injury.
If you and your child leave the vehicle, always
make sure that the child restraint system is
not in direct sunlight. Cover it with a blanket, for example. If the child restraint system has
been exposed to direct sunlight, leave it to
cool down before securing the child in it.
Never leave children unattended in the vehi-
cle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting
properly. Particular attention must be paid to
children.
Observe the safety notes on the seat belt
(Y page 44) and the information on the correct
use of the seat belt (Y page 45). Children in the vehicle
