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 to
accommodate a person with disabilities, con- tact 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 G
WARNING
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. There is an increased risk of serious or even
fatal injuries.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop.
PASSENGER AIRBAG indicator lamp
PASSENGER AIR BAG OFF indicator lamp
:
and PASSENGER AIR BAG ON indicator
lamp ;are part of the automatic deactiva-
tion system of the front-passenger front air-
bag.
The indicator lamps display the status of the
front-passenger front airbag.
R PASSENGER AIR BAG ON lights up: the
front-passenger front airbag is enabled. If,
in the event of an accident, all deployment
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.
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 rearward-facing child
restraint system: the PASSENGER AIR
BAG OFF indicator lamp must be lit. The
front-passenger front airbag is disabled. It
is imperative to observe the notes on the Occupant safety
43Safety Z

"Automatic front-passenger front airbag
deactivation system" (Y page 51) and on
"Children in the vehicle" (Y page 60).
R Children in a forward-facing child
restraint system: depending on the instal-
led child restraint system and the age and
size of the child, the front-passenger front
airbag is either disabled or enabled. There-
fore, it is imperative to observe the notes
on the "Automatic front-passenger front
airbag deactivation system" (Y page 51)
and on "Children in the vehicle"
(Y page 60).
R All other persons: the PASSENGER AIR
BAG ON indicator lamp must be lit. 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.
It is imperative to observe the notes on the
"Automatic front-passenger front airbag
deactivation system" (Y page 51) as well
as on "Seat belts" (Y page 44) and "Air-
bags" (Y page 48). There you can also find
information on the correct seat position. 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 seat-belt extender, the inertia reel locks.
The belt strap cannot be pulled out any fur-
ther.
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, correct an 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 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
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 properly and are
seated correctly. 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 44
Occupant safetySafety

The belt strap is tightened slightly when:
R with a retracted seat-belt extender, the
seat belt tongue is engaged in the belt
buckle and
R the ignition is switched on
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the vehicle occupant and the seat
belt. Do not hold on to the seat belt tightly
while it is adjusting.
You can switch the seat-belt adjustment on
and off using COMAND Online. Information
on activating and deactivating the seat-belt
adjustment function can be found in the Dig-
ital Owner's Manual.
Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle
occupants must wear their seat belts. It may
light up continuously or flash. In addition, a
warning tone may sound.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the front passenger have fastened their seat
belts.
i For more information on the
7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belt" (Y page 302).
Rear seat belt status indicator The rear seat belt status indicator is only
available for certain countries.
For approximately 30 seconds, the rear seat
belt status indicator informs you which rear
seat belt is not fastened.
The rear seat belt status indicator appears if:
R you drive off and reach a speed of approx-
imately 10 km/h
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion
R someone gets in or out of the vehicle and
you pull away again
You can also cancel the rear seat belt status
indicator immediately (Y page 266). Airbags
Introduction The installation location of an airbag is iden-
tified by the AIRBAG symbol.
An airbag supplements a correctly worn seat
belt. It is not a replacement for the seat belt.
The airbag offers additional protection in
applicable accident situations.
Not all airbags are deployed in an accident.
The different airbag systems work independ-
ently of each other (Y page 57).
However, no system available today can com- pletely eliminate injuries and fatalities.
It is also not possible to completely rule out a
risk of injury caused by an airbag due to the
speed at which the airbag must be deployed.
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. 48
Occupant safetySafety

front airbag both before and during the jour-
ney.
If a person is sitting on the front-passenger
seat, this person 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 56). 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 seat-belt extender to the shoulder
belt guide on the child restraint system. The
shoulder belt strap must be routed forwards
and downwards from the retracted seat-belt
extender. If necessary, adjust the front- Occupant safety

Z

passenger seat accordingly. Always observe
the information about suitable positioning of
the child restraint system in this Owner's
Manual as well as the child restraint system
manufacturer's installation instructions.
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
child 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 in "Child restraint systems on the front- passenger seat" (Y page 63) and in "Suit-
able positioning of the child restraint sys-
tem" (Y page 65). Alternatively, you can fit the child restraint system to a suitable
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.
If children are travelling in the vehicle, be sure
to observe the notes on "Children in the vehi-
cle" (Y page 60).
If the automatic front-passenger front airbag
deactivation system is malfunctioning, the
red 6 restraint system warning lamp in
the instrument cluster and the PASSENGER
AIR BAG OFF indicator lamp light up simulta-
neously. The front-passenger front airbag is
disabled in this case and does not deploy dur- ing an accident. Have the system checked as
soon as possible by qualified technicians.
Consult a Mercedes-Benz Service Centre. The
front-passenger seat should only be repaired at a Mercedes-Benz Service Centre.
If the front-passenger seat, the seat cover orthe seat cushion is damaged, have the nec-
essary repair work carried out at a Mercedes- Benz Service Centre.
For safety reasons, Mercedes-Benz recom-
mends that you only use a child restraint sys-
tem which has been tested and approved by 54

Mercedes-Benz in combination with the auto-
matic front-passenger front airbag deactiva-
tion system.
System self-test G
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
WARNING
Objects between the seat surface and the
child restraint system could affect the func-
tion of the automatic front-passenger front
airbag deactivation system. This could result
in the front-passenger front airbag not func-
tioning as intended during an accident. This
poses an increased risk of injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. The
entire base of the child restraint system must always rest on the seat cushion of the front-
passenger seat. The backrest of the forwards-
facing child restraint system must, as far as
possible, be resting on the backrest of the
rear reclining seat. Always comply with the
child restraint system manufacturer's instal-
lation instructions.
After the system self-test, the PASSENGER
AIR BAG OFF or PASSENGER AIR BAG ON
indicator lamp display the status of the front- passenger front airbag (Y page 52).
Further information can be found under
"Problems with the automatic front-
passenger front airbag deactivation system"
(Y page 56). Occupant safety
