Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have accessories retrofitted at a qualified
specialist workshop.
You could jeopardise the operating safety of
your vehicle if you use parts, tyres and wheels
as well as accessories relevant to safety
which have not been approved by Mercedes. This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. Use
only genuine Mercedes-Benz parts or parts of
equal quality. Only use tyres, wheels and
accessories that have been specifically
approved for your vehicle.
Mercedes-Benz tests genuine parts and con-
version parts and accessories that have been specifically approved for your vehicle for their
reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Mercedes-Benz therefore accepts no responsibility for the
use of such parts in Mercedes-Benz vehicles, even if they have been officially approved or
independently approved by a testing centre.
In Germany, certain parts are only officially
approved for installation or modification if
they comply with legal requirements. This
also applies to some other countries. All gen-
uine Mercedes-Benz parts meet the approval
requirements. The use of non-approved parts may invalidate the vehicle's general operating
permit.
This is the case:
R if they cause a change of the vehicle type
from that for which the vehicle's general
operating permit was granted
R if other road users could be endangered
R if the emission or noise levels are adversely
affected
Always specify the vehicle identification num- ber (VIN) when ordering genuine Mercedes-
Benz parts (Y page 398). Owner's Manual

Introduction to the restraint system
The restraint system reduces the risk of vehi- cle occupants coming into contact with parts
of the vehicle's interior in the event of an
accident. Furthermore, the restraint system
can also reduce the forces to which vehicle
occupants are subjected during an accident.
The restraint system includes:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing system
The various components of the restraint sys-
tem work complementary to one another. It
can only provide maximum protection if all
vehicle occupants:
R have their seat belt correctly fastened
(Y page 45)
R have correctly adjusted their seat and head
restraint (Y page 105).
As the driver, you must also ensure that the
steering wheel is correctly adjusted. Observe
the information relating to the correct driver's
seat position (Y page 104).
Additionally, you must ensure that an airbag
can deploy freely (Y page 48).
An airbag is supplementary to a correctly fas- tened seatbelt and, as an additional safety
device, provides greater protection for vehi-
cle occupants in an accident situation. If the
protection provided by the seat belt is suffi-
cient, the airbags do not deploy. Furthermore,
in the event of an accident, only airbags which
provide greater protection in the given acci-
dent situation deploy. However, seat belts
and airbags generally do not protect against
objects penetrating the vehicle from the out- side.
Information on how the restraint system
operates can be found in "Deployment of the
seat belt tensioner and airbags"
(Y page 51). 42

mation on children travelling in the vehicle as
well as on child restraint systems

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

will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam- aged seat belts can no longer fulfil their
protective function and must be replaced.
Visit a qualified specialist workshop. X

Seat belt adjustment The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. This
function adjusts the driver's and front-
passenger seat belt to the upper body of the
occupants.
The belt strap is tightened slightly when:
R the seat belt tongue is engaged in the belt
buckle and
R the ignition is switched on
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the vehicle occupant and the seat
belt. Do not hold on to the seat belt tightly
while it is adjusting.
You can switch the seat-belt adjustment on
and off in the on-board computer
(Y page 257). Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder for all vehicle occu-
pants to 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 switches off as soon as the driver and co-driver have fastened their seat
belts.
i For more information on the
7seat
belt warning lamp, see the "Warning and
indicator lamps in the instrument cluster,
seat belt" section (Y page 287).
Rear seat belt status indicator The seat belt on the right rear seat, when viewed in
the direction of travel, is not fastened. (Example:
CLS Coupé)
The status indicator for the rear-compart-
ment seat belts is only available 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 261). Occupant safety
47Safety Z

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 on which the impact
occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a windowbag may be deployed in
other accident situations (Y page 51).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 after an
accident, you have your vehicle towed to a
qualified specialist workshop. This is particu- larly important after the seat belt tensioners
have been triggered or after airbags have
been deployed.
An electric motor is used by PRE-SAFE ®
to
trigger the tightening of the seat belt in haz-
ardous situations. This procedure is reversi-
ble.
If belt tensioners are triggered or the airbags
are 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
hearing. The powder that is released gener-
ally does not constitute a health hazard but
can cause short-term breathing difficulties for people with asthma or breathing problems. If
it is safe to do so, leave the vehicle immedi-
ately or open a window to avoid experiencing potential breathing difficulties.
Mode of operation During the first stage of a collision, the
restraint system control unit evaluates impor-
tant physical data relating to vehicle deceler- ation or acceleration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the seat belt tensioner is triggered by the restraint
system control unit in the event of a frontal or
rear collision.
The belt tensioner can only be triggered if:
R the ignition is switched on
R the components of the restraint system are
operational; see the "Restraint system
warning lamp" section (Y page 43)
R the seat belt buckle tongue is engaged in
the belt buckle on your front seat
The belt tensioners in the rear compartment
are triggered independently of the lock status of the seat belts.
In certain frontal collision situations, further
components of the restraint system are acti-
vated independently of each other if the
restraint system control unit determines that the accident is severe:
R front airbags and driver's kneebag
R windowbag, if it is determined that it can
offer additional protection to the seat belt
for vehicle occupants
Depending on the classification of the person in the front-passenger seat, the front- Occupant safety

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
