Driver's kneebag
:deploys under the steering
column. The driver's kneebag is triggered
together with the front airbags.
The driver's kneebag offers additional thigh,
knee and lower leg protection for the occupant
in the driver's seat.
i The driver's kneebag is only available in cer-
tain countries.

WARNING
Unsuitable seat covers may obstruct or even
prevent deployment of the airbags integrated into the seats. The airbags may then fail to
protect the vehicle occupants as intended.
Operation of the automatic child seat recog-
nition may also be impaired. There is an
increased risk of injury, possibly even fatal.
Use only seat covers which have been specif-
ically approved for the respective seat by
Mercedes-Benz. Front sidebags
:and rear sidebags ;deploy
next to the outer bolster of the seat backrest.
When deployed, the sidebag offers additional
thorax protection. However, it does not protect
the:

Windowbags Occupant safety
43Safety Z

Windowbags
:are integrated into 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 which the 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 44).Deployment of belt tensioners and air-
bags
Important safety notes G
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
Pyrotechnic seat belt tensioners that have
been deployed are no longer operational and
are unable to perform their intended protec-
tive function. This poses an increased risk of
injury or even fatal injury.
Therefore, have pyrotechnic belt tensioners
which have been triggered immediately
replaced at a qualified specialist workshop.
Mercedes-Benz recommends that you have the
vehicle towed to a qualified specialist workshop
after an accident. Take this into account, par-
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 only be triggered 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 37)
R the belt 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 collisions,
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
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 only be deployed in an accident if the PASSENGER AIR BAG OFF indicator lamp is off.
Observe the information on the PASSENGER AIR
BAG OFF indicator lamp (Y page 37).
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. 44
Occupant safetySafety

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 which can only be seen and measured
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 which 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
deformation. This is the case if, for example,
very rigid vehicle parts such as longitudinal body
members are hit, and sufficient deceleration
occurs as a result.
If the restraint system control unit detects a side impact, the applicable components of the
restraint system are activated independently of
each other.
R Sidebags and pelvisbag on the side on which
an impact occurs, independent from the seat
belt tensioner and seat belt usage
Vehicles with the automatic child seat recog- nition on the front-passenger seat: the side-
bag and pelvisbag on the front-passenger side (front) deploy under the following conditions:
- an occupant is detected on the front-
passenger seat or
- the belt tongue is engaged in the belt
buckle of the front-passenger seat
R Windowbag on the side on which an impact
occurs, independent of seat belt usage and
regardless of whether the front-passenger
seat is occupied
R Seat belt tensioners, if the system determines
that deployment can offer additional protec-
tion for the vehicle occupants in this situation i
Not all airbags are deployed in an accident.
The different airbag systems work independ-
ently of each other.
How the airbag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration, and the apparent type of accident:
R frontal collision
R side impact NECK-PRO head restraints
Important safety notes G
WARNING
The function of the head restraint may be
impaired if you:
R attach objects such as coat hangers to the
head restraints, for example
R use unsuitable head restraint covers
If you do so, the head restraints cannot fulfil
their intended protective function in the event of an accident. In addition, objects attached
to the head restraints could endanger other
vehicle occupants. This poses an increased
risk of injury.
Do not attach any objects to the head
restraints and only use suitable head restraint
covers.
Consult a Mercedes-Benz Service Centre
regarding the availability of suitable seat or head
restraint covers.
Operation NECK-PRO head restraints reduce the likelihood
of head and chest injuries. The NECK-PRO head
restraints on the driver's and front-passenger
seats are moved forwards and upwards in the
event of a rear-end collision of a certain severity. This provides better head support.
If the NECK-PRO head restraints have been trig-
gered in an accident, you must reset the NECK-
PRO head restraints on the driver's and front-
passenger seat (Y page 46). Otherwise, the
additional protection will not be available in the
event of another rear-end collision. You can rec- ognise when NECK-PRO head restraints have Occupant safety

the front-passenger seat
The sensor system for the automatic child seat
recognition in the front-passenger seat detects
whether a special Mercedes-Benz child restraint
system with transponders has been fitted. In
this case, the PASSENGER AIR BAG OFF indica-
tor lamp lights up and remains lit. The front-
passenger front airbag is disabled.
i If the front-passenger front airbag is disa-
bled by the automatic child seat recognition,
the following remain enabled on the front-
passenger side:
R the sidebag
R the pelvisbag
R the windowbag
R the belt tensioner G
WARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front airbag can
deploy in the event of an accident. The child could be struck by the airbag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air-
bag has been disabled. The PASSENGER AIR-
BAG OFF indicator lamp must be lit. 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.
In this case the front-passenger seat may not be used. You may only transport a child on the
front-passenger seat if they are seated in a
suitable rearward or forward-facing child
restraint system. Always observe the infor-
mation about suitable positioning of the child restraint system in this Owner's Manual as
well as the child restraint system manufac-
turer's installation instructions. 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.
Move the front-passenger seat as far back as
possible. 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 down- Children in the vehicle

wards from the retracted seat-belt extender.
If necessary, adjust the front-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 manufac-
turer's installation instructions.
i Ensure that your vehicle is equipped with
automatic child seat recognition for the front-
passenger seat (Y page 52). If this is not the
case, always install a child restraint system on a suitable rear seat (Y page 55).PASSENGER AIR BAG OFF indicator lamp

airbag is disabled.
X Turn the key to position 1or 2in the ignition
lock or, on vehicles with KEYLESS-GO, press
the Start/Stop button once or twice.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
If, after the system self-test, the
PASSENGER AIR BAG OFF indicator lamp:
R lights up , the front-passenger front airbag is
disabled. It will then not be deployed in the
event of an accident.
R is not lit , the sensor system did not detect a
child restraint system with transponder for
automatic child seat recognition. If, in the
case of an accident, all deployment criteria
are met, the front-passenger front airbag is
deployed. G
WARNING
Electronic devices on the front-passenger
seat can affect the function of the automatic
child seat recognition, for example:
R laptop
R mobile phone
R transponder cards such as ski passes or
access passes
The front-passenger front airbag could deploy unintentionally or not function as intended
during an accident. This poses an increased
risk of injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat. Be aware of the status of the front-passenger front airbag both before and
during the journey. 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 seats. For this reason, Mercedes-
Benz strongly advises that you fit a child
restraint system on a rear seat.
Vehicles with automatic child seat recognition
on the co-driver's seat: if it is absolutely neces-
sary to fit a child restraint system to the co-driv- er's seat, always observe the notes on "Auto-
matic child seat recognition on the co-driver's
seat" (Y page 52).
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 child seat recognition's sen-
sor system
R the unintentional disabling of the co-driver's
front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board. 52

Please observe the warning notice on the co-
driver's sun visor, see the illustration. G
WARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front airbag can
deploy in the event of an accident. The child
could be struck by the airbag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air-
bag 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 AIRBAG in front of
it, DEATH or SERIOUS INJURY to the CHILD can
occur.
Vehicles without automatic child seat
recognition on the co-driver's seat If the co-driver's seat of your vehicle is not
equipped with automatic child seat recognition,
this is indicated by a special sticker. The sticker is affixed to the side of the dashboard on the co- driver's side. The sticker is visible when you
open the co-driver's door.
The PASSENGER AIR BAG OFF indicator lamp
lights up briefly when the key is turned to posi-
tion

however, and does not indicate that the co-driv-
er's seat is equipped with automatic child seat
recognition.
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. They have no function, however, and do not indicate that the co-driver's seat is equip- ped with automatic child seat recognition.
Always fit the rearward-facing restraint system
to a suitable rear seat in this case (Y page 55).
Observe the following information under "Rear-
ward-facing child restraint system" and
"Forward-facing child restraint system" and on
suitable positioning of the child restraint system (Y page 55).
Rearward-facing child restraint system Warning symbol for a rearward-facing child
restraint system
If it is absolutely necessary to fit a rearward-
facing child restraint system to the co-driver's
seat, you must always make sure that the co-
driver's front airbag is deactivated. The co-driv-
er's front airbag is only disabled if the
PASSENGER AIRBAG OFF indicator lamp is lit
