Introduction to the restraint system
The restraint system reduces the risk of vehi- cle occupants coming into contact with parts
of the vehicle's interior in the event of 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
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 43)
R have the seat and head restraint adjusted
properly (Y page 97)
As the driver, you must also make sure that
the steering wheel is also adjusted properly.
Observe the information on the correct driv-
er's seat position (Y page 96).
In addition, you must make sure that the air-
bags can inflate properly if they are deployed (Y page 45).
An airbag supplements a correctly worn seat belt. As an additional safety device, the airbag
increases the level of protection for vehicle
occupants in the event of an accident. The
airbags are not deployed, for example, in the event of an accident in which sufficient pro-
tection is offered by the seat belt. In addition,
only those airbags, which in the applicable
accident situations offer additional protec-
tion, are deployed in the event of an accident.
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 "Deployment of
belt tensioners and airbags" (Y page 47).
See "Children in the vehicle" for further infor- mation on children travelling in the vehicle as 40
Occupant safetySafety

Depending on the person in the front-
passenger seat, the front-passenger front air-
bag must either be disabled or enabled; see
the following points. You must make sure of
this both before and during a journey.
R Children in a child restraint system:
whether the front-passenger front airbag is
enabled or disabled depends on the instal-led child restraint system, and the age and size of the child. Therefore, always observe
the information on "Children in the vehicle" (Y page 51). There you will also find
instructions on backwards and forwards-
facing child restraint systems on the front- passenger seat.
R All other persons: the PASSENGER AIR
BAG OFF indicator lamp must be off. Be
sure to observe the notes on "Seat belts"
(Y page 42) and "Airbags" (Y page 45).
There you can also find information on the
correct seat position.
Observe the information on automatic child
seat recognition in the front-passenger seat
(Y page 52). Seat belts
Introduction A correctly worn seat belt is the most effec-
tive means of restraining the movement of
vehicle occupants in the event of a collision or
if the vehicle overturns. This reduces the risk
of vehicle occupants coming into contact with
parts of the vehicle interior or being ejected
from it. The seat belt also helps to keep the
vehicle occupants in the best position in rela-
tion to the airbag being deployed.
The seat belt system consists of:
R seat belts
R belt tensioners and belt force limiters
If the seat belt is pulled quickly or sharply by
the belt loop, the inertia reel locks. The belt
strap cannot be pulled out any further.
The belt tensioner tightens the seat belt in the
event of a collision so that it fits tightly across your body. However, it does not pull the vehi-
cle occupants back in the direction of the seat backrest.
The belt tensioner does not, however, correctan incorrect seat position or correct the rout-
ing of a seat belt that is worn incorrectly.
When triggered, seat belt force limiters help
to reduce the peak force exerted by the seat
belt on the vehicle occupant.
The belt force limiters are synchronised with
the front airbags, which take on a part of the
deceleration force. This can reduce the forces
to which the vehicle occupants are subjected during an accident.
! If the co-driver's seat is not occupied, do
not engage the seat belt tongue in the
buckle on the co-driver's seat. Otherwise,
the belt tensioner could be triggered in the
event of an accident and would have to be
replaced.
Important safety notes G
WARNING
The seat belt cannot perform its intended pro- tective function if it is not fastened correctly. Also, an improperly fastened seat belt can
cause additional injuries in the event of an
accident, sudden braking or abrupt changes
of direction. There is an increased risk of
injury, possibly even fatal.
Always make sure that all vehicle occupants
are wearing their seat belt and positioned cor-
rectly. G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest 42

The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. Infor-
mation about the convenience function can
be found under "Belt adjustment"
(Y page 45). 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 warning lamps are activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered
R in vehicles with a memory function: the
electrically adjustable steering wheel is
raised
R the engine is switched off
R vehicles with the Mercedes-Benz emer-
gency call system: automatic emergency
call Children in the vehicle
Important safety notes
If a child younger than 12 years old and under
1.50 m in height is travelling in the vehicle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate 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 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 sit-
ting properly. Particular attention must be
paid to children.
Observe the safety notes on the seat belt
(Y page 42) and the information on the cor-
rect use of the seat belt (Y page 43). Children in the vehicle

R lights up , the front-passenger front airbag
is disabled. It will then not be deployed in
the event of an accident.
R is not lit, the sensor system did not detect
a child 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 front air-
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 front airbag 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 front airbag both before and
during the journey. Child restraint system on the front-
passenger seat
General notes If you secure a child in a child restraint system
on the front-passenger seat, always observe
the information on "Automatic child seat rec-
ognition on the front-passenger seat"
(Y page 52).
You can thus avoid the risks that could arise
as a result of:
R a child restraint system that is not detected
by the automatic child seat recognition
sensor system
R the unintentional disabling of the front-
passenger front airbag
R the unsuitable positioning of the 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.
G
WARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
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. 54
