Introduction to the restraint system
The restraint system can reduce the risk of vehi- cle occupants coming into contact with parts of
the vehicle's interior in the event of an accident.
The restraint system can also reduce the forces to which vehicle occupants are subjected during
an accident.
The restraint system comprises:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing systems The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if all vehicle
occupants always:
R fasten their seat belts correctly
(Y page 39)
R adjust their seat and head restraint properly
(Y page 93).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (Y page 93).
You also have to make sure that an airbag can
inflate properly if deployed (Y page 41).
An airbag supplements a correctly fastened seat belt. As an additional safety device, the airbag
increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if the protection of the seat belt is sufficient in an accident, the airbags are not deployed. In
the event of an accident, only the airbags that
increase protection in the relevant accident sit- uation are deployed. However, seat belts and
airbags generally do not protect against objects penetrating the vehicle from the outside.
Information on the restraint system operation
can be found under "Triggering of belt tension-
ers and airbags" (Y page 44).
For more information about children travelling
with you in the vehicle, see "Children in the vehi-
cle" (Y page 47). Important safety notes
G
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 a Mercedes-Benz Service Centre. 36
Occupant safetySafety

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
:
shows you whether the front-passenger front
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

and
R the vehicle speed is between approximately
7 km/h and 200 km/h
At a speed of up to approximately 70 km/h,
PRE-SAFE ®
Brake can also detect:
R stationary objects in the path of your vehicle,
e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle
i If there is an increased risk of a collision,
preventive passenger protection measures
(PRE-SAFE ®
) are triggered (Y page 46).
If the risk of a collision with the vehicle in front
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking up
to the point of full brake application. Automatic
emergency braking is not performed until imme- diately prior to an imminent accident.
You can prevent the intervention of PRE-SAFE ®
Brake at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal
The braking action of PRE-SAFE ®
Brake is ended
automatically if:
R you manoeuvre to avoid the obstacle
R there is no longer a risk of collision
R there is no longer an obstacle detected in
front of your vehicle STEER CONTROL
General notes STEER CONTROL helps you by transmitting a
noticeable steering force to the steering wheel
in the direction required for vehicle stabilisation.
This steering support is provided in particular if:
R ESP ®
is deactivated
R both right wheels or both left wheels are on a
slippery road surface when you brake heavily
R the vehicle starts to skid
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 61). No steering support is provided by STEER CON-
TROL, if:
R ESP ®
is malfunctioning
R the steering is faulty
Power steering will, however, continue to func-
tion. Protection against theft
