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. 44
Occupant safetySafety

The restraint system includes:
R seat belt system
R airbags
R child restraint system
R child seat securing systems
The components of the restraint system are
complementary. They can offer maximum
protection only when all vehicle occupants:
R secure their seat belts correctly
(Y page 48)
R adjust the seat and head restraints prop-
erly (Y page 119)
As the driver, you must also make sure that
the steering wheel is adjusted correctly.
Observe the information on the correct driv-
er's seat position (Y page 118).
Additionally, you must make sure that the air- bag can inflate without restriction if deployed
(Y page 51).
An airbag is supplementary to a correctly fas-
tened seatbelt. An airbag, as an additional
safety device, provides greater protection for vehicle occupants in an accident situation. If
the seat belts offer sufficient protection in the
event of an accident, for example, the airbags
will not be deployed. Also, only the airbags
which are deemed to offer protection in the
corresponding accident situation are
deployed. However, seat belts and airbags
generally do not protect against objects pen-
etrating the vehicle from the outside.
Information on how the restraint system
operates can be found in "Deployment of the seat belt tensioner and airbags"
(Y page 60).
See "Children in the vehicle" (Y page 63) for
further information on infants and children
travelling in the vehicle as well as on child
restraint systems. 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 modify an airbag system
for a person with physical disabilities, contact a Mercedes-Benz Service Centre for details. Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at regular intervals while the engine is run-
ning. Therefore, malfunctions can be detec-
ted in good time.
The 6 restraint system warning lamp in
the instrument cluster lights up when the igni- tion is switched on. It goes out no later than afew seconds after the vehicle is started. The
components of the restraint system are in
operational readiness.
A malfunction has occurred if the 6
restraint system warning lamp:
R does not light up after the ignition is
switched on
R does not go out after a few seconds with
the engine running
R lights up again while the engine is running

DANGER
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This can
effect belt tensioners or airbags, for example. In addition, the vehicle's high-voltage electri-
cal system may not be deactivated as inten-
ded in the event of an accident. Touching
damaged components of the vehicle's high-
voltage electrical system could result in an
electric shock. There is an increased risk of
injury, possibly even fatal.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. After an accident, immediately
switch the ignition off and remove the key
from the ignition lock. PASSENGER AIRBAG indicator lamp

Occupant safetySafety

In the event of a side impact, the windowbag
is deployed on the side on which the impact
occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a windowbag may be deployed in
other accident situations (Y page 60).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 sys- tem categorises 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
deactivation system (Y page 66). If this is
not the case, always install a child restraint
system on a suitable rear seat (Y page 68).
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. cushions. 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 the forward-facing child restraint system must, as far as possible, be resting onthe 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. Only then is the correct function of the automatic front- passenger front airbag deactivation system
guaranteed. Always observe the information
on suitable positioning of the child restraint
system (Y page 68) in addition to the child
restraint system manufacturer's installation
instructions.
Operation of automatic front-passenger

The indicator lamps inform you whether the
front-passenger front airbag is disabled or
enabled. 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 simultaneously for approx-
imately six seconds.
The indicator lamps display the status of the
front-passenger front airbag.
R PASSENGER AIR BAG ON :lights up: the

Occupant safetySafety

criteria are met, the front-passenger front
airbag is deployed.
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 status of the front-passenger front air-
bag changes while the vehicle is in motion, an
airbag display message appears in the instru-
ment cluster (Y page 330). When the front-
passenger seat is occupied, always pay atten-
tion to the PASSENGER AIR BAG ON and
PASSENGER AIR BAG OFF indicator lamps. Be aware of the status of the front-passenger
front airbag both before and during the jour-
ney.
If there is no child restraint system fitted to
the front-passenger seat, the front passenger must sit:
R with the seat belt fastened correctly
R in an almost upright position with their
back against the seat backrest
R with their feet resting on the floor, if possi-
ble
If the front passenger does not observe these
conditions, the automatic front-passenger
front airbag deactivation system may be influ- enced, e.g. because the front passenger:
R transfers their weight by supporting them-
selves on a vehicle armrest
R sits in such a way that their weight is raised
from the seat cushion
The front-passenger front airbag may be dis-
abled by mistake as a result of these or similar
actions. In this case, the PASSENGER AIR
BAG OFF indicator lamp lights up perma-
nently. The front-passenger front airbag does not then deploy during an accident. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp is lit, the front-passenger front airbag is disa-
bled. It will not be deployed in the event of an
accident and cannot perform its intended pro-
tective function. A person in the front-
passenger seat could then, for example, come into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always make sure that:
R the classification of the person in the front-
passenger seat is correct and that the front- passenger front airbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front airbag is correct. G
WARNING
If you secure a child on the co-driver's seat in a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The childcould be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
If the PASSENGER AIR BAG OFF indicator
lamp remains off and/or the PASSENGER AIR BAG ON indicator lamp lights up, do not install
a rearward-facing child restraint system on
the front-passenger seat. Further information can be found under "Problems with the auto-matic front-passenger front airbag deactiva-
tion system" (Y page 59). Occupant safety

G
WARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the airbag if the PASSENGER
AIR BAG ON indicator lamp is lit
This poses an increased risk of injury or even fatal injury.
Always move the front-passenger seat as far
back as possible and fully retract the seat
cushion length. 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 shoul-
der belt strap must be routed forwards and
downwards from the vehicle belt outlet. If
necessary, adjust the vehicle belt outlet and
the front-passenger seat accordingly. Always
observe the information about suitable posi-
tioning of the child restraint system in this
Owner's Manual as well as the child restraint system manufacturer's installation instruc-
tions.
If the automatic front-passenger front airbag
deactivation system detects that:
R the front-passenger seat is unoccupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger front airbag is disabled.
R the front-passenger seat is occupied by a
child in a rearward-facing child restraint
system, the PASSENGER AIR BAG OFF indi-
cator lamp lights up after the system self-
test and remains lit. This indicates that the
front-passenger front airbag is disabled.
But in the case of a child in a rearward-
facing child restraint, the PASSENGER AIR
BAG ON indicator lamp can light up after
the system self-test and remain lit. This indicates that the front-passenger front air-
bag is enabled. The result of the classifica-
tion is dependent on, among other factors, the child restraint system and the child's
build. It is recommended that you fit the
restraint system to a suitable rear seat.
R the front-passenger seat is occupied by a
child in a forward-facing child restraint sys-
tem, either the PASSENGER AIR BAG ON or
PASSENGER AIR BAG OFF indicator lamp
lights up and remains lit after the system
self-test depending on the result of the
classification. The result of the classifica-
tion is dependent on, among other factors,
the child restraint system and the child's
build.
Move the front-passenger seat as far back
as possible. Always observe the informa-
tion on "Child restraint systems on the
front-passenger seat" (Y page 66) and on
"Suitable positioning of the child restraint
system" (Y page 68). Alternatively, you
can fit the child restraint system to a suit-
able rear seat.
R the front-passenger seat is occupied by a
person with a smaller build (e.g. a teenager
or small adult), either the PASSENGER AIR
BAG ON or PASSENGER AIR BAG OFF indi- cator lamp lights up and remains lit after
the system self-test depending on the
result of the classification.
- if the PASSENGER AIR BAG ON indicator
lamp lights up, move the front-passenger seat as far back as possible. Alterna-
tively, a person with a small build can sit on a rear seat.
- if the PASSENGER AIR BAG OFF indicator
lamp is lit, a person with a smaller build
should not use the front-passenger seat.
R the front-passenger seat is occupied by an
adult or a person with a build correspond-
ing to that of an adult, the PASSENGER AIR BAG ON indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenger front airbag
is enabled. 56

DANGER
If both the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not light up during the system self-test, the
system is malfunctioning. The front-
passenger front airbag might be triggered
unintentionally or might not be triggered at all in the event of an accident with high deceler-
ation. This poses an increased risk of injury or even fatal injury.
In this case the front-passenger seat may notbe used. Do not install a child restraint system
on the front-passenger seat. Have the auto-
matic front-passenger front airbag deactiva-
tion system checked and repaired immedi-
ately at a qualified specialist workshop. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp remains lit after the system self-test, the
front-passenger front airbag is disabled. It willnot be deployed in the event of an accident. In
this case, the front-passenger front airbag
cannot perform its intended protective func-
tion, e.g. when a person is seated in the front- passenger seat.
That person could, for example, come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash-
board. This poses an increased risk of injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
R the classification of the person in the front-
passenger seat is correct and the front-
passenger front airbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the person is seated properly with a cor-
rectly fastened seat belt.
R the front-passenger seat has been moved
as far back as possible.
If the PASSENGER AIR BAG OFF indicator
lamp remains lit when it should not, the front- passenger seat may not be used. Do not
install a child restraint system on the front-
passenger seat. Have the automatic front-
passenger front airbag deactivation system
checked and repaired immediately at a quali-
fied specialist workshop. G
