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 occu-
pants 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 More information on the
7seat belt
warning lamp can be found under "Warning
and indicator lamps in the instrument cluster,
seat belt" (Y page 254).
Rear seat belt status indicator The seat belt on the left rear seat, when viewed
in the direction of travel, is not fastened. (Exam- ple)
The rear seat belt status indicator is only avail-
able for certain countries.
The rear seat belt status indicator shows which rear seat belt is not fastened.

Introduction The installation location of an airbag is identified
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 corre-
sponding accident situations. Not all airbags are deployed in an accident. The
different airbag systems work independently of
each other (Y page 45).
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.
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 Only hold the steering wheel on the outside.
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. 42
Occupant safetySafety

If a child is travelling in your vehicle, also
observe the following notes:
R Always secure children under twelve years of
age and less than 1.50 mtall in suitable child
restraint systems.
R Child restraint systems should be fitted to the
rear seats.
R Only secure a child to the front-passenger
seat when the front-passenger front airbag is
disabled, and only then in a rearward-facing
child restraint system. If the PASSENGER AIR
BAG OFF indicator lamp is permanently lit, the
front-passenger front airbag is disabled
(Y page 38).
R Always observe the instructions and safety
notes on "Children in the vehicle"
(Y page 49) and on the "Child restraint sys-
tem on the front-passenger seat"
(Y page 53) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions.
Objects in the vehicle interior may prevent
the airbag from functioning correctly. Before
starting your journey and to avoid risks resulting from the speed of the airbag as it deploys, make
sure that:
R there are no people, animals or objects
between the vehicle occupants and an airbag.
R there are no objects between the seat, door
and B-pillar.
R no hard objects, e.g. coat hangers, are hang-
ing on the grab handles or coat hooks.
R no accessories, such as cup holders, are
attached to the vehicle within the deployment
area of an airbag, e.g. to doors, side windows, rear side trim or side walls.
R no heavy, sharp-edged or fragile objects are in
the pockets of your clothing. Store such
objects in a suitable place. G
WARNING
If you modify an airbag cover or affix objects
such as stickers to it, the airbag can no longer function correctly. There is an increased risk
of injury.
Never modify an airbag cover or affix objects
to it. G
WARNING
Sensors to control the airbags are located in
the doors. Modifications or work not per- formed correctly to the doors or door panel-
ling, as well as damaged doors, can lead to the
function of the sensors being impaired. The
airbags might therefore not function properly any more. Consequently, the airbags cannot
protect vehicle occupants as they are
designed to do. This poses an increased risk
of injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door pan-
elling carried out at a qualified specialist
workshop.
Front airbags Driver's airbag
:deploys in front of the steer-
ing wheel. Front-passenger front airbag ;
deploys in front of and above the glove com-
partment.
When deployed, the front airbags offer addi-
tional head and thorax protection for the occu-
pants in the front seats.
A permanently lit PASSENGER AIR BAG OFF
indicator lamp informs you that the front-
passenger front airbag is disabled (Y page 38).
Driver's kneebag Occupant safety
43Safety Z

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.
Sidebags G
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:
R head
R neck
R arms
In the event of a side impact, the sidebag is
deployed on the side on which the impact
occurs. Headbags
Headbags
:deploy in the area of the side win-
dows at the front.
When deployed, the headbag enhances the level
of protection for the head. However, it does not protect the:
R chest
R arms
In the event of a side impact, the headbag 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 headbag may be deployed in other
accident situations (Y page 45).
Pelvisbags G
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. 44
Occupant safetySafety

Pelvisbags
:deploy next to and below the
outer seat cushions.
When activated, the pelvisbag enhances the
level of protection of the vehicle occupants on
the side of the vehicle on which the impact
occurs.
The pelvisbag is deployed on the side of the
impact.
i Pelvisbags are only available in certain
countries. Roll bars
G
DANGER
If the roll bar has developed a fault, it may not function, e.g. in the event of an accident. The
roll bars may then not protect the vehicle
occupants as intended. This poses an
increased risk of injury or even fatal injury.
Have roll bars checked immediately at a quali-
fied specialist workshop. G
WARNING
Risk of injury if the roll bar is triggered.
Ensure that the movement area of the rear
head restraints is kept clear.
The roll bars are under the rear head restraints. They extend if systems detect that the vehicle isin danger of overturning. Thus the rear head
restraints also extend automatically.
Once the roll bars are extended, you can no lon-
ger lower the rear head restraints. An open soft
top can no longer be closed. In this case, visit
the nearest qualified specialist workshop. 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. Occupant safety
45Safety Z

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 38)
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 headbag, 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 38).
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 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 or if the vehicle overturns, the applicablecomponents of the restraint system are activa-
ted independently of each other depending on
the apparent type of accident.
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 Headbag 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
R Headbags on the driver's and front-passenger
side in certain situations if the vehicle over-
turns and if the system determines that
deployment can offer additional protection to that provided by the seat belt 46
Occupant safetySafety

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
R overturn 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 47). 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
been triggered by the fact that they have moved
forwards and can no longer be adjusted.
Mercedes-Benz recommends that you have the
NECK-PRO head restraints checked for func-
tionality at a qualified specialist workshop after a rear-end collision.
Resetting triggered NECK-PRO head
restraints Do not place your fingers between the uphols-
tery of the head restraint and the seat. Pay par-
ticular attention while resetting the NECK-PRO
head restraints.
X Tilt the top of the NECK-PRO head restraint
cushion forwards in the direction of arrow :.
X Push the NECK-PRO head restraint cushion
down as far as it will go in the direction of
arrow ;.
X Firmly push the NECK-PRO head restraint
cushion back in the direction of arrow =until
the cushion engages.
X Repeat this procedure for the second NECK-
PRO head restraint.
i Resetting the NECK-PRO head restraints
requires a lot of strength. If you have difficulty
resetting the NECK-PRO head restraints, have this work carried out at a qualified specialist
workshop. PRE-SAFE

G
WARNING
ISOFIX child restraint systems do not offer
sufficient protective effect for children whose weight is greater than 22 kg who are securedusing the safety belt integrated in the child
restraint system. The child could, for example, not be restrained correctly in the event of an
accident. This poses an increased risk of
injury or even fatal injury.
If the child weighs more than 22 kg, only use
ISOFIX child restraint systems with which the child is also secured with the vehicle seat belt. Also secure the child restraint system with the
Top Tether belt, if available.
Always observe the notes on using the child
restraint system (Y page 55) as well as the
installation and operating instructions provided
by the manufacturer for the child restraint sys-
tem being used. Before each journey, make sure that the ISOFIX
child restraint system is properly engaged in
both ISOFIX securing rings. ISOFIX securing rings
:are located between
the seat cushion and the seat backrest.
X Install the ISOFIX child restraint system on
both ISOFIX securing rings :.
ISOFIX is a standardised securing system for
special child restraint systems on the rear seats.
ISOFIX securing rings for two ISOFIX child
restraint systems are fitted on the left and right of the rear seats.
Mercedes-Benz recommends the use of the lis-
ted ISOFIX child restraint systems together with the insertion guides included (Y page 58).
Using insertion guides makes it easier to fit ISO- FIX child restraint systems.
Secure child restraint systems without an ISO-
FIX child seat securing system using the seat
belts in the vehicle. Always observe the notes on
using the child restraint system (Y page 55) as
well as the installation and operating instruc-
tions provided by the manufacturer for the child restraint system being used. Automatic child seat recognition on
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. Children in the vehicle

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 headbag
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-
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 53). If this is not the
case, always install a child restraint system on a suitable rear seat (Y page 55).52
