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 102).
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 102).
Additionally, you must ensure that an airbag can
deploy freely (Y page 47).
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 54).
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 57). 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

protective function. Furthermore, an incor-
rectly 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 secure persons less than 1.50 mtall in
additional suitable restraint systems.
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 this Mercedes-Benz vehi-
cle. The child restraint system must be appro- priate to the age, weight and size of the child.
R always observe the instructions and safety
notes on the "Automatic front-passenger
front airbag deactivation system"
(Y page 50)
R always observe the instructions and safety
notes on "Children in the vehicle"
(Y page 57) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions. G
WARNING
Seat belts cannot protect as intended, if:
R they are damaged, have been modified, are
extremely dirty, bleached or dyed
R the seat belt buckle is damaged or
extremely dirty
R modifications have been made to the belt
tensioners, belt anchorages or inertia reels
Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modi-
fied or damaged seat belts can tear or fail, for example in the event of an accident. Modified
seat belt tensioners may be deployed unin-
tentionally or not function as intended. There is an increased risk of injury, possibly even
fatal.
Never modify seat belts, seat belt tensioners,
seat belt anchorages and inertia reels. Ensure that seat belts are not damaged or worn and
are clean. After an accident, have the seat
belts checked immediately at a qualified spe-
cialist workshop. Mercedes-Benz recommends that you only use
seat belts which have been approved specifi-
cally for your vehicle by Mercedes-Benz. Other-
wise, your vehicle's general operating permit
could be invalidated.
Correct seat belt use Pay attention to the safety notes about the seat
belt (Y page 44).
All vehicle occupants must fasten their seat
belts correctly before you start driving. You
must also make sure that all vehicle occupants
have fastened their seat belts correctly during
the journey.
When fastening your seat belt, always make
sure that:
R the seat belt tongue is inserted into the belt
buckle that belongs to the seat.
R the seat belt is tightened across your body.
Avoid wearing bulky clothing, e.g. a winter
coat.
R the seat belt is not twisted.
Only then can the forces which occur be dis-
tributed over the area of the belt.
R the shoulder section of the belt is always
routed across the centre of your shoulder.
The shoulder section of the belt must not
come into contact with your neck or be routed under your arm. Adjust the seat belt to the
appropriate height as necessary.
R The lap belt must be taut and as low as pos-
sible over your lap.
The lap belt must always be routed across
your hip joints and not across your abdomen.
Pregnant women must take particular care
with this. If necessary, push the lap belt down to your hip joint and pull it tight using the
shoulder section of the belt.
R The seat belt is not routed over sharp, pointed
or fragile objects.
If such objects are located on or in your cloth- ing, e.g. pens, keys, spectacles, etc. stow
these in a suitable location.
R Only one person should use each seat belt at
any one time.
Babies and children must never travel sitting
on the lap of another vehicle occupant. In the Occupant safety

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 54).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
In the following situation, the sidebag and the
seat belt tensioner are deactivated:
R the automatic front-passenger front airbag
deactivation system has not categorised the
person in the front-passenger seat as an adult or a person of corresponding stature and
R the seat belt tongue of the seat belt is not
inserted into the front-passenger seat belt
buckle
Make sure that your vehicle is equipped with the
automatic front-passenger front airbag deacti-
vation system (Y page 61). If this is not the
case, always install a child restraint system on a
suitable rear seat (Y page 62).
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. The entire base of the child restraint
system must always rest on the seat cushion of the front-passenger seat. The backrest of the
forward-facing child restraint system must, as
far as possible, be resting on 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 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 62) in addition to the
child restraint system manufacturer's installa-
tion instructions.
Operation of automatic front-passenger
front airbag deactivation :
PASSENGER AIR BAG ON indicator lamp
; PASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether the
front-passenger front airbag is disabled or ena-
bled.
X Press the Start/Stop button once or twice, or
turn the key to position 1or 2in the ignition
lock.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul- taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front airbag:
R PASSENGER AIR BAG ON lights up for 60 sec-
onds, then both indicator lamps are off
(PASSENGER AIR BAG ON and OFF): the front-
passenger front airbag is able to deploy in the
event of an accident.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front-passenger
front airbag. The PASSENGER AIR BAG OFF indi-
cator lamp may be lit continuously or be off. 50

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 notes on how to use the seat
belt properly (Y page 45). Child restraint system
If you fit a rearward-facing child restraint system
to the centre rear seat, the rear arm rest must be folded back as far as possible.
Observe the instructions for correct use of the
child restraint system (Y page 62).
For safety reasons, Mercedes-Benz recom-
mends that you use only a child restraint system recommended by Mercedes-Benz
(Y page 65). G
WARNING
If the child restraint system is incorrectly fit-
ted on the seat position suitable for this pur-
pose, it cannot perform its intended protec-
tive function. In the event of an accident,
sharp braking or a sudden change in direction, the child may not be held securely. There is an
increased risk of serious or even fatal injuries.
Observe the manufacturer's installation
instructions and the correct use for the child
restraint system. Make sure that the entire
surface of the child restraint system is resting
on the seat surface. Never place objects
under or behind the child restraint system,
e.g. cushions. Only use child restraint sys-
tems with the original cover designed for
them. Only replace damaged covers with gen- uine covers. G
WARNING
If the child restraint system is fitted incor-
rectly or is not secured, it can come loose in
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system could be thrown about, strik- ing vehicle occupants. There is an increased
risk of injury, possibly even fatal.
Always fit child restraint systems properly,
even if they are not being used. Make sure
that you observe the child restraint system
manufacturer's installation instructions.

guidelines" (Y page 312).58
Children in the vehicleSafety

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 62).
Observe the following information under "Rear-
ward-facing child restraint system"
(Y page 62) and "Forward-facing child
restraint system" (Y page 62) as well as infor-
mation on the suitable positioning of the child
restraint system (Y page 62).
Rearward-facing child restraint system If it is absolutely necessary to fit a rearward-
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 43) is the front-
passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 62) in addition to the child restraint
system manufacturer's installation and operat-
ing instructions.
Forward-facing child restraint system If it is absolutely necessary to fit a forward-
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 shoulder belt strap is correctly routed from the vehicle belt outlet to
the shoulder belt guide on the child restraint
system. The shoulder belt strap must be routed
forwards and downwards from the vehicle belt
outlet. If necessary, adjust the vehicle belt out-
let and the front-passenger seat accordingly.
Always observe the information on suitable
positioning of the child restraint system
