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

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 event of an accident, they could be crushed
between the vehicle occupant and seat belt.
R Do not secure any objects with a seat belt if
the seat belt is being used by one of the vehi-
cle's occupants.
You must also make sure that objects, e.g.
cushions, are never placed between a person and the seat.
Seat belts are solely intended to secure and
restrain persons. To secure objects, luggage or
loads, always observe the "Loading guidelines"
(Y page 305).
Fastening and adjusting the seat belts Observe the safety notes on seat belts
(Y
page 43) and the information on correct use
of seat belts (Y page 44).
If a passenger is wearing the centre rear seat
belt, also observe the information on the seat
belt for the centre rear seat (Y page 45).Basic illustration

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.
In the event of a side impact, the windowbag is
deployed on the side on which an 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.
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. Occupant safety

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.
R Sidebags on the side of the impact, independ-
ent of the seat belt tensioner and seat belt
usage 54

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.
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). 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.
