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. 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 securing system The components of the restraint system work in
conjunction with each other. They can only offerprotection if all vehicle occupants always:
R have the seat belt correctly fastened
(Y page 44)
R have the seat and head restraint adjusted
properly (Y page 106)
As the driver, you must also make sure that the
steering wheel is also adjusted properly.
Observe the information on the correct driver's
seat position (Y page 106).
In addition, you must make sure that the airbags can inflate properly if they are deployed
(Y page 46).
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 air-
bags are not deployed, for example, in the event
of an accident in which sufficient protection is
offered by the seat belt. In addition, only those
airbags, which in the applicable accident situa-
tions offer additional protection, are deployed in the event of an accident. However, the seat beltand airbag generally do not protect against
objects penetrating the vehicle from the out-
side.
Information on how the restraint system oper-
ates can be found under "Deployment of belt
tensioners and airbags" (Y page 53).
See "Children in the vehicle" for information on
children travelling with you in the vehicle as well
as on child restraint systems (Y page 56). 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 it is necessary to adjust the vehicle to accom- modate a person with disabilities, contact a
qualified specialist workshop. Occupant safety

tion system" (Y
page 49) and on "Children in
the vehicle" (Y page 56).
R All other persons: the PASSENGER AIR BAG
OFF indicator lamp must be off. The front-
passenger front airbag is enabled. Depending
on the build of the person on the front-
passenger seat, the PASSENGER AIR BAG
OFF indicator lamp may light up. The front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident. In this case, the front-passenger seat should not
be used.
Make sure that you read the notes on the
"Automatic front-passenger front airbag
deactivation system" (Y page 49) as well as
on "Seat belts" (Y page 43) and "Airbags"
(Y page 46). There, you can also find infor-
mation on the correct seat position. Seat belts
Introduction A correctly worn seat belt is the most effective
means of restraining the movement of vehicle
occupants in the event of a collision or if the
vehicle overturns. This reduces the risk of vehi-
cle occupants coming into contact with parts of
the vehicle interior or being ejected from it. The seat belt also helps to keep the vehicle occu-
pants in the best position in relation to the air-
bag being deployed.
The seat belt system consists of:
R seat belts
R belt tensioners for the front seat belts and the
outer seat belts in the rear
R belt force limiters for the front seat belts and
the outer seat belts in the rear
If the seat belt is pulled quickly or sharply from
the belt outlet, 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 vehicle
occupants back in the direction of the seat
backrest.
The belt tensioner does not, however, correct an
incorrect seat position or correct the routing 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 on the front seats are
synchronised with the front airbags, which take
on a part of the deceleration force. This can
reduce the forces to which the vehicle occu-
pants are subjected during an accident.
! If the front-passenger seat is not occupied,
do not engage the seat belt tongue in the
buckle on the front-passenger seat. Other-
wise, the belt tensioner and sidebag could be
triggered in the event of an accident and
would need to be replaced.
Important safety notes G
WARNING
If the seat belt is worn incorrectly, it cannot
perform its intended protective function. Fur- thermore, an incorrectly worn seat belt can
cause additional injuries, e.g. in the event of
an accident, heavy braking or sudden
changes of direction. There is an increased
risk of injury, possibly even fatal.
Always ensure that all vehicle occupants have their seat belts fastened correctly and are sit-
ting properly.
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 44)
R have the seat and head restraint adjusted
properly (Y page 106) 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
is in an almost vertical position and that the
shoulder section of your seatbelt is routed
across the centre of your shoulder. Occupant safety

Windowbags
Windowbags
:are integrated in the side of the
roof frame and deploy in the area from the A-
pillar to the C-pillar.
When deployed, the windowbag enhances the
level of protection for the head. However, it does
not protect the chest or arms.
When the restraint system control unit detects a side impact, the windowbag is deployed on the
side on which the impact occurs.
If the system determines that it can offer addi-
tional protection to that provided by the seat
belt, a windowbag may be deployed in other
accident situations (Y page 53).Automatic front-passenger front air-
bag deactivation
Introduction In order to recognise a child restraint system on
the front-passenger seat, the automatic front-
passenger front airbag deactivation system cat- egorises the person in the front-passenger seat.Depending on that result, the front-passenger
front airbag is either enabled or disabled. If a
rearward-facing child restraint system is fitted
to the front-passenger seat, the PASSENGER
AIR BAG OFF indicator lamp must light up after
the system self-test and remain lit. The front-
passenger front airbag is disabled.
The system does not disable:
R the sidebag
R the windowbag
R the seat belt tensioner
Make sure that your vehicle is equipped with the automatic front-passenger front airbag deacti-
vation system (Y page 60). If this is not the case, always install a child restraint system on a
suitable rear seat (Y page 61).
If it is absolutely necessary to install a child
restraint system on the front-passenger seat, be
sure to observe the correct positioning of the
child restraint system. Never place objects
under or behind the child restraint system, e.g. a
cushion. Fully retract the seat cushion length.
The entire base of the child restraint system
must always rest on the seat cushion of the
front-passenger seat. The backrest of a forward-
facing child restraint system must, as far as
possible, rest flat against the backrest of the
front-passenger seat. The child restraint system must not touch the roof or be put under strain bythe head restraint. Adjust the angle of the seat
backrest and the head restraint position accord-
ingly. Only then is the correct function of the
automatic front-passenger front airbag deacti-
vation system guaranteed. Always observe the
information on suitable positioning of the child
restraint system (Y page 61) in addition to the
child restraint system manufacturer's installa-
tion instructions.

dent
Immediately after an accident, the following
measures may be 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 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
on the rear seats are safer than children secured
on the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install the child restraint system on a rear seat. Chil-
dren are generally better protected there.
If a child younger than twelve years old and
under 1.50 m in 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 49). 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 43) and the information on the correct
use of the seat belt (Y page 44).56
Children in the vehicleSafety

Top Tether
Introduction Top Tether provides an additional connection
between the child restraint system secured with
ISOFIX or i-Size and the vehicle. It helps reduce
the risk of injury even further. If the child
restraint system is fitted with a Top Tether belt,
this should always be used.
Important safety notes G
WARNING
If the rear seat backrests are not locked, they
could fold forwards in the event of an acci-
dent, heavy braking or sudden changes of
direction. As a result, child restraint systems
cannot perform their intended protective
function. Rear seat backrests that are not
locked can also cause additional injuries, e.g. in the event of an accident. This poses an
increased risk of injury or even fatal injury.
Always lock rear seat backrests after fitting a Top Tether belt. Observe the lock verificationindicator. Adjust the rear seat backrests so
that they are in an upright position.
If the rear seat backrest is not engaged and
locked, the red lock verification indicator will be
visible (Y page 292).
Top Tether anchorages The Top Tether anchorage points are located on
the rear side of the backrests on both outer rear seats.
Vehicles with adjustable head restraints:
X Move head restraint :upwards.
X Route Top Tether belt ?under head
restraint :between the two head restraint
bars.
Vehicles without adjustable head restraints:
X Top Tether belt with one belt strap: route

that you do not interfere with the correct rout-
ing of Top Tether belt ?.Child restraint system on the front-
passenger seat
General notes Accident statistics show that children secured
on the rear seats are safer than children secured on the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
a child restraint system on a rear seat.
Vehicles with the automatic front-
passenger front airbag deactivation system:
if it is absolutely necessary to fit a child restraint
system to the front-passenger seat, always
observe the information on the "Automatic
front-passenger front airbag deactivation sys-
tem" (Y page 49).
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 front-passenger front airbag
deactivation system
R unintentional disabling of the front-passenger
front airbag
R unsuitable positioning of the child restraint
system, e.g. too close to the dashboard Please observe the warning notice on the
front-passenger sun visor; see illustration. G
WARNING
If you secure a child in a rearward-facing 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.
NEVER use a rearward-facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it; DEATH or SERIOUS INJURY to the
child can occur.
If the PASSENGER AIR BAG OFF indicator lamp
goes out, the front-passenger front airbag is
enabled (Y page 42).
Vehicles without the automatic front-
passenger front airbag deactivation
system If the front-passenger seat of your vehicle is not
equipped with the automatic front-passenger
front airbag deactivation system, this is indica-
ted by a special sticker. The sticker is affixed to
the side of the dashboard 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 and
PASSENGER AIR BAG ON indicator lamps light
up briefly. However, they have no function and
do not indicate that there is an automatic front- passenger front airbag deactivation system.
In this case, never fit a rearward-facing child
restraint system on the front passenger seat
(Y page 61).
Observe the following information under "Rear-
ward-facing child restraint system"
(Y page 61) and "Forward-facing child
restraint system" (Y page 61) as well as infor-
mation on the suitable positioning of the child
restraint system (Y page 61).60
