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 an authorised Mercedes-Benz Centre. Restraint system warning lamp
The operation of the restraint system is
checked when the ignition is switched on and at regular intervals while the engine is run-
ning. This allows malfunctions to be quickly
identified.
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 a few seconds after the engine is started. The
various 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 when the ignition is
switched on
R does not go out after a few seconds while
the engine is 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 AIR BAG OFF indicator
lamp
PASSENGER AIR BAG OFF indicator lamp
:
is part of the automatic child seat recognition
on the front-passenger seat.
A permanently lit PASSENGER AIR BAG OFF
indicator lamp informs you that the front-
passenger front airbag is disabled.
Depending on the person in the front-
passenger seat, the front-passenger front air-
bag must either be disabled or enabled. You
must make sure of this both before and during a journey.
R Children in a child restraint system:
whether the front-passenger front airbag is
enabled or disabled depends on the instal-led child restraint system, and the age and size of the child. Therefore, always observe
the information on "Children in the vehicle" (Y page 55). There you will also find
instructions on backwards and forwards- Occupant safety

Airbags
Introduction The AIRBAG symbol indicates the installation
location of an airbag.
The airbag is supplementary to a correctly
fastened seatbelt. It does not replace a seat- belt. The airbag serves to provide additional
protection in an accident situation.
Not all airbags are deployed in an accident.
The various airbag systems work independ-
ently of one another (Y page 51).
However, no system available today can com- pletely eliminate injuries and fatalities.
Due to the speed of airbag deployment, it is
also not possible to entirely rule out the risk of
injuries caused by the driver's airbag deploy-
ing.
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 position must allow the vehicle to be
driven safely.
R Only hold the steering wheel on the out-
side. 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 other-
wise be in the deployment area of the air-
bags.
R Always keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may oth-
erwise be in the deployment area of the
airbag.
R For this reason, always secure persons less
than 1.50 mtall in suitable restraint sys-
tems. Up to this height, the seat belt cannot
be worn correctly.
If a child is travelling in your vehicle, also
observe the following notes:
R Always secure children under 12 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 43).
R Always observe the instructions and safety
notes on "Children in the vehicle"
(Y page 55) and on the "Child restraint
system on the front-passenger seat"
(Y page 61) in addition to the child
restraint system manufacturer's installa-
tion instructions. 48

passenger front airbag is disabled or enabled.
Only when the PASSENGER AIR BAG OFF indi-cator lamp is not lit, can the co-driver's airbag
be deployed in the event of an accident.
Observe the information on the PASSENGER
AIR BAG OFF indicator lamp (Y page 43).
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 a second deployment threshold is reached
within a few milliseconds.
The evaluation of the activation threshold for
a seat belt tensioner and airbag involves an
assessment of the deceleration or accelera-
tion dynamics that occur at different points
on the vehicle. This process functions pre-
emptively. Deployment must take place
promptly at the beginning of the collision.
The rate of vehicle deceleration or accelera-
tion and the direction of the force are essen- tially determined by:
R the distribution of the force during the
impact
R the collision angle
R the deformation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured after the collision has occurred do not play a
decisive role in the deployment of an airbag,
nor do they provide an indication of airbag
deployment.
The vehicle can be substantially deformed
without the driver's airbag being deployed.
This is the case if only relatively easily deform-
able vehicle parts are affected by the collision
and a high deceleration threshold is not
reached. On the other hand, airbags may be
deployed even though the vehicle only dis-
plays minor deformation. This is the case if,
for example, very rigid vehicle parts such as
longitudinal body members are hit, and suffi-
cient deceleration occurs as a result. When the restraint system control unit
detects a side impact or determines that the
vehicle has overturned, the corresponding
components of the restraint system are acti-
vated independently of each other, depend-
ing on the type of accident that has occurred.
If the system determines in this situation that
it can offer additional protection for vehicle
occupants, the seat belt tensioners are also
triggered.
R Sidebags and pelvisbag on the side on
which impact occurs, independent of the
belt tensioner and seat belt use
Vehicles with automatic child seat recog-
nition in the co-driver's seat: the sidebag
and pelvisbag on the co-driver's side
deploy under the following conditions:
- an occupant is detected on the co-driv-
er's seat, or
- the seat belt buckle tongue is engaged in
the belt buckle on the co-driver's seat
R The windowbag on the side on which
impact occurs, independent of seat belt
use and regardless of whether the co-driv-
er's seat is occupied
R Windowbags on the driver's and co-driver's
sides in certain situations where the vehicle
overturns, if it is determined that they can
offer additional protection to the seat belt
for vehicle occupants
i Not all airbags are deployed in an acci-
dent. The various airbag systems work
independently of one another.
How the airbag system works is deter-
mined by the severity of the accident detec- ted, especially the vehicle deceleration or
acceleration, and the apparent type of acci- dent:
R frontal collision
R side impact
R overturn 52

the front-passenger seat
The sensor system for child restraint systems
in the front-passenger seat detects whether a special Mercedes-Benz child restraint system
with a transponder for automatic child seat
recognition has been fitted. In this case, the
PASSENGER AIR BAG OFF indicator lamp lights up and remains lit. The front-passenger
front airbag is disabled.
i If the front-passenger front airbag is dis-
abled by the automatic child seat recogni-
tion, 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. Only suitable rearward-facing or
forward-facing child restraint systems may be installed on the front-passenger seat. 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. Children in the vehicle
59Safety Z

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
belt sash guide to the shoulder belt guide on
the child restraint system. The shoulder belt
strap must be routed forwards and down-
wards from the vehicle belt sash guide. If nec-
essary, adjust the vehicle belt sash guide 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.
i Ensure that your vehicle is equipped with
automatic child seat recognition for the
front-passenger seat (Y page 61). If this
is not the case, always fit the child restraint
system on a suitable rear seat
(Y page 63). PASSENGER AIR BAG OFF indicator lamp
:
shows you whether the front-passenger front airbag is disabled.
X Turn the key to position 1or 2in the ignition
lock, or press the Start/Stop button once
or twice on vehicles with KEYLESS-GO.
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 is lit, the front-passenger front airbag is
disabled. They 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 cri-
teria are met, the front-passenger front air-
bag 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 thefront-passenger front airbag both before and
during the journey. 60
Children in the vehicleSafety

Child restraint system on the front-
passenger seat
General notes Accident statistics show that children
secured in the rear seats are safer than chil-
dren 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 automatic child seat recogni-
tion on the front-passenger seat: if it is abso- lutely necessary to fit a child restraint systemto the front-passenger seat, always observe
the information on the "Automatic child seat
recognition on the front-passenger seat"
(Y page 59).
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
sensor system
R the unintentional disabling of the front-
passenger front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board Please observe the warning notice on the
front-passenger sun visor, see the illustra-
tion. 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 front-passenger seat If the front-passenger seat of your vehicle is
not equipped with automatic child seat rec-
ognition, this is indicated by a special sticker. The sticker is affixed to the side of the dash-
board on the front-passenger side. The
sticker is visible when you open the front-
passenger door.
If you turn the key to position 2in the ignition
lock, the PASSENGER AIR BAG OFF indicator lamp lights up briefly. It has no function, how-ever, and does not indicate that the front-
passenger seat is equipped with automatic
child seat recognition.
In this case, always fit the rearward-facing
child restraint system to a suitable rear seat
(Y page 63).

ating instructions.
Forward-facing child restraint system If it is absolutely necessary to fit a forward-
facing child restraint system to the front-
passenger seat, always move the front-
passenger seat as far back as possible.
Always make sure that the shoulder belt strap is correctly routed from the vehicle belt outlet to the shoulder belt guide on the child
restraint system. The shoulder 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.
