Useful information
i This Owner's Manual describes all models,
series and optional equipment for your vehi-
cle that were available at the time of going to
press. National variations are possible. Note
that your vehicle may not be equipped with all
of the functions described. This is also the
case for systems and functions relevant to
safety.
i Read the information on qualified specialist
workshops: (Y page 23). Occupant safety
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 37)
R adjust their seat and head restraint properly
(Y page 87).
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 86).
You also have to make sure that an airbag can
inflate properly if deployed (Y page 39).
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 46).
For more information about children travelling
with you in the vehicle, see "Children in the vehi-
cle" (Y page 49). 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 for details. Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at
regular intervals while the drive system is run-
ning. Therefore, malfunctions can be detected in good time.
The 6 restraint system warning lamp in the
instrument cluster lights up when the ignition is switched on. It goes out no later than a few sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 6restraint
system warning lamp:
R does not light up after the ignition is switched
on
R does not go out after a few seconds with the
drive system running
R lights up again while the drive system is run-
ning 34
Occupant safetySafety

Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster reminds you that all vehicle occu-
pants must fasten their seat belts. It may light up continuously or flash. A warning tone may also
sound.
The 7 seat belt warning lamp goes out and
the warning tone stops as soon as the driver's
and the co-driver's seat belts have been fas-
tened.
i For more information on the
7seat belt
warning lamp, see "Warning and indicator
lamps in the instrument cluster, seat belt"
(Y page 214).
Rear seat belt status indicator The seat belts on the left and centre rear seats,
when viewed in the direction of travel, are not
fastened. (Example)
The rear seat belt status indicator is only avail-
able for certain countries.
For approximately 30 seconds, the rear seat belt status indicator informs you which rear seat belt
is not fastened.
The rear seat belt status indicator appears if:
R you drive off and reach a speed of approx-
imately 10 km/h
R the rear passengers fasten or unfasten their
seat belts while the vehicle is in motion
R someone gets in or out of the vehicle and you
pull away again
You can also cancel the rear seat belt status
indicator immediately (Y page 189).Airbags
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 applicable
accident situations.
Not all airbags are deployed in an accident. The
different airbag systems work independently of
each other (Y page 46).
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- Occupant safety
