R All other persons: the PASSENGER AIR BAG
OFF indicator lamp must be off. The front-
passenger front airbag is enabled. Depending
on the stature 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 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.
If the seat belt is also fitted with a belt force
limiter and this is triggered, the force exerted by
the seat belt on the vehicle occupant is reduced. 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 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 ten-
sioner could be triggered in the event of an
accident and would have 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. 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. G
WARNING
Persons under 1.50 mtall cannot wear the
seat belts correctly without an additional suit- able restraint system. If the seat belt is worn
incorrectly, it cannot perform its intended
protective function. Furthermore, an incor-
rectly worn seat belt can cause additional
injuries, e.g. in the event of an accident, heavy Occupant safety
43Safety
Z

The belt adjustment will apply a certain tighten-
ing 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 activate and deactivate the belt adjust-
ment via the multimedia system. Information on
activating and deactivating the belt adjustment
can be found in the Digital Owner's Manual.
Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster reminds you that all vehicle occu-
pants must fasten their seat belts. It may light up continuously or flash. A warning tone may also
sound.
The 7 seat belt warning lamp goes out and
the warning tone stops as soon as the driver's
and the co-driver's seat belts have been fas-
tened.
Rear seat belt status indicator The rear seat belt status indicator is available
only in certain countries.
The rear seat belt status indicator informs you
which rear seat belt is not fastened.
Cancelling the rear seat belt status indicator
immediately (Y
page 248). Airbags
Introduction The airbag installation location is identified by
the label AIRBAG.
An airbag supplements a correctly fastened seat
belt. It is not a substitute for seat belts. The air-
bag provides additional protection in the corre-
sponding accident situations.
Not all airbags are deployed in an accident. The
various airbag systems work independently of
one another (Y page 53). However, no system available today can com-
pletely eliminate injuries and fatalities.
Due to the required speed of the airbag after
deployment, it is also not possible to entirely
rule out the risk of injuries caused by the airbag.
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.
In order to avoid such risks, always ensure
that all vehicle occupants:
R fasten their seatbelts correctly, including
pregnant women
R are seated correctly and maintain the fur-
thest possible distance from the airbags
R observe the following notes
Always ensure that there are no objects loca-
ted between the airbag and the vehicle occu-
pant.
R Adjust the seats properly before beginning
your journey. Always make sure that the seat
is in an almost upright position. The centre of
the head restraint must support the head at
about eye level.
R Move the driver's and front-passenger seats
as far back as possible. The driver's seat posi-
tion must allow the vehicle to be driven safely.
R Hold the steering wheel only by the rim. This
allows the airbag to be fully deployed.
R Always lean against the backrest while driv-
ing. Do not lean forwards or lean against the
door or side window. You may otherwise be in the deployment area of the airbags.
R Always keep your feet in the footwell in front
of the seat. Do not put your feet on the dash-
board, for example. Your feet may otherwise
be in the deployment area of the airbag.
R Always secure persons less than 1.50 mtall in
suitable restraint systems. Up to this height,
the seat belt cannot be worn correctly. 46
Occupant safetySafety

If the status of the front-passenger front airbag
changes while the vehicle is in motion, an airbag display message appears on the instrument
cluster (Y page 259). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger front airbag both before and during the journey.
If a person sits in the passenger seat, he/she
must be:
R seated with the seat belt fastened correctly
R in an almost upright position with his/her
back against the seat backrest
R with his/her feet resting on the floor, if pos-
sible
If the front passenger does not observe these
conditions, the automatic front-passenger front
airbag deactivation system may be influenced,
e.g. because the front passenger:
R transfers his/her weight by supporting him-
self/herself on a vehicle armrest
R sits in such a way that his/her weight is raised
from the seat cushion
The front-passenger front airbag may be disa-
bled by mistake as a result of these or similar
actions. In this case, the PASSENGER AIR BAG
OFF indicator lamp lights up permanently. The
front-passenger front airbag then does not
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 in a rearward-facing child
restraint system on the co-driver's seat and
the PASSENGER AIR BAG OFF indicator lamp
is off, the co-driver's front airbag can deploy in the event of an accident. The child could be
struck by the airbag. There is an increased risk
of injury, possibly even fatal.
In this case, always make sure that the co-
driver's front airbag has been disabled. The
PASSENGER AIR BAG OFF indicator lamp
must be lit.
If the PASSENGER AIR BAG OFF indicator lamp
stays off, do not install a rearward-facing child
restraint system on the front-passenger seat.
Further information can be found under "Prob-
lems with the automatic front-passenger front
airbag deactivation system" (Y page 53). 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 OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.

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.
Always observe the vehicle-specific information for the correct positioning of the child restraint
system (Y page 61).
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 sys-
tem, 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.
But in the case of a child in a rearward-facing
child restraint system, the PASSENGER AIR
BAG OFF indicator lamp can also go out after
the system self-test. This indicates that the
front-passenger front airbag is enabled. The
result of the classification is dependent on,
among other factors, the child restraint sys-
tem and the child's stature. It is recommen-
ded 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 OFF
indicator lamp lights up and remains lit after
the system self-test depending on the result
of the classification, or it goes out. The result
of the classification is dependent on, among
other factors, the child restraint system and
the child's stature.
Move the front-passenger seat as far back as possible. Always observe the information in
"Child restraint systems on the front-
passenger seat" (Y page 60) and in "Suita-
ble positioning of the child restraint system" (Y
page 61). Alternatively, you can fit the
child restraint system to a suitable rear seat.
R the front-passenger seat is occupied by a per-
son of smaller stature (e.g. a teenager or
small adult), the PASSENGER AIR BAG OFF
indicator lamp lights up and remains lit after
the system self-test depending on the result
of the classification or, alternatively, goes out.
- If the PASSENGER AIR BAG OFF indicator
lamp is off, move the front-passenger seat
as far back as possible. Alternatively, a per-
son with a small stature can sit on a rear
seat.
- If the PASSENGER AIR BAG OFF indicator
lamp is lit, a person with a smaller stature
should not use the front-passenger seat.
R the front-passenger seat is occupied by an
adult or a person with the stature of an adult,
the PASSENGER AIR BAG OFF indicator lamp
goes out after the system self-test. 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 vehicle"
(Y page 56).
If the automatic front-passenger front airbag
deactivation system is malfunctioning, the red
6 restraint system warning lamp on the
instrument cluster and the PASSENGER AIR
BAG OFF indicator lamp light up simultaneously.
The front-passenger front airbag is disabled in
this case and does not deploy during an acci-
dent. Have the automatic front-passenger front
airbag deactivation system checked and
repaired immediately at a qualified specialist
workshop. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for this purpose.
If the front-passenger seat, the seat cover or the
seat cushion are damaged, have the necessary

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 shows the status of the front-passenger
front airbag (Y page 49). If the front-passenger
front airbag is enabled, the PASSENGER AIR
BAG ON indicator lamp lights up for 60 seconds
and then goes out.
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.

WARNING
After the airbag deploys, the airbag parts are
hot. There is a risk of injury.
Do not touch the airbag parts. Have a
deployed airbag replaced at a qualified spe-
cialist workshop as soon as possible. G
WARNING
Pyrotechnical belt tensioners which have
been triggered are no longer operational and
therefore cannot protect as intended. There is an increased risk of injury, possibly even fatal.
Have pyrotechnic belt tensioners which have
been triggered replaced at a qualified special-

ticularly if a seat belt tensioner was triggered or
an airbag was deployed.
An electric motor is used by PRE-SAFE ®
to trig-
ger the tightening of the seat belt in hazardous
situations. This procedure is reversible.
If the belt tensioners are triggered or an airbag is
deployed, you will hear a bang, and a small
amount of powder may also be released. The
6 restraint system warning lamp lights up.
Only in rare cases will the bang affect your hear-
ing. In general, the powder released is not haz-
ardous to health but may cause short-term
breathing difficulties to persons suffering from
asthma or other pulmonary conditions. Provided it is safe to do so, you should leave the vehicle
immediately or open the window in order to pre- vent breathing difficulties.
Operation During the first stage of a collision, the restraint
system control unit evaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the
restraint system control unit triggers the seat
belt tensioners in the event of a head-on or rear
collision.
A seat belt tensioner can be triggered only if:
R the ignition is switched on
R the components of the restraint system are
operational. You can find further information
under: "Restraint system warning lamp"
(Y page 42)
R the seat belt buckle tongue has engaged in
the belt buckle of the respective front seat
The seat belt tensioners in the rear compart-
ment are triggered independently of the lock
status of the seat belts.
If the restraint system control unit detects a
high-severity accident, in certain head-on colli-
sions, additional components of the restraint
system are deployed independently of each
other:
R Front airbags and driver's kneebag
R Windowbag, if the system determines that
deployment can offer additional protection to that provided by the seat belt On vehicles with the automatic front-passenger
front airbag deactivation system: depending on
the person in the front-passenger seat, the
front-passenger front airbag is either disabled or enabled. The front-passenger front airbag can
be deployed in an accident only if the
PASSENGER AIR BAG OFF indicator lamp is off.
Observe the information on the PASSENGER AIR BAG indicator lamps (Y page 42).
Your vehicle has two-stage front airbags. In the
first deployment stage, the front airbag is filled
with propellant gas to reduce the risk of injuries. The front airbag is fully deployed if the second
deployment stage is activated within a few mil-
liseconds.
The activation threshold for the seat belt ten-
sioners and airbags is determined based on the
evaluation of the vehicle's rate of deceleration
or acceleration at various points in the vehicle.
This process is pre-emptive in nature. The trig-
gering/deployment process should take place
in good time at the start of the collision.
The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
determined by:
R the distribution of forces during the collision
R the collision angle
R the deformation characteristics of the vehicle
R the characteristics of the object with which
the vehicle has collided
Factors that can be seen and measured only
after a collision has occurred do not play a deci-
sive role in the deployment of an airbag, nor do
they provide an indication of airbag deployment.
The vehicle may be deformed significantly with-
out an airbag being deployed. This is the case if only parts that are relatively easily deformed are
affected and the rate of deceleration is not high. Conversely, an airbag may be deployed even
though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as a result.
If the restraint system control unit detects a side
impact or if the vehicle overturns, the applicable components of the restraint system are activa-
ted independently of each other depending on
the apparent type of accident.

Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
a child restraint system on a rear seat. Children are generally better protected there.
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 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).56

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 P
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.

(Y page 43) and the information on the correct
use of the seat belt (Y page 44). Child restraint system
Observe the instructions for correct use of the
child restraint system (Y page 61).
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.

that you do not interfere with the correct rout-
ing of Top Tether belt B.Child restraint system on the front-
passenger seat
General notes Accident statistics show that children secured
in the rear seats are safer than children secured
in 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 abso-
lutely necessary to fit a child restraint system to the front-passenger seat, always observe the
information on the "Automatic front-passenger
front airbag deactivation system" (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 co-driver's seat and
the PASSENGER AIR BAG OFF indicator lamp
is off, the co-driver's front airbag can deploy in the event of an accident. The child could be
struck by the airbag. There is an increased risk
of injury, possibly even fatal.
In this case, always make sure that the co-
driver's front airbag 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 FRONT AIRBAG;
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). 60
