the front airba
gisfilledwith enoug hpropel-
lant ga storeducethe risk of injuries .The
front airbag is fully deployed if asecond
deployment threshold is exceeded within a
few milliseconds.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration or acceleration of the
vehicle. This process is pre-emptive in nature.
The triggering process must take place in
good time at the start of the collision.
i Airbags are not deployed in all types of
accidents. Also, not all airbags are
deployed together in an accident. The dif-
ferent airbag systems work independently
of each other.
How the airbag system works is deter-
mined by the severity of the collision detec-
ted, especiallyt he vehicle deceleration or
acceleration, and the apparent type of acci-
dent:
R head-on collision
R side impact
R rear impact
R Cabriolet: overturn
The rate of vehicle deceleration or accelera-
tion and the direction of the force are essen-
tially determined by:
R the distribution of forces during the colli-
sion
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 acollision 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 may be deformed significantly,
e.g. the bonnet or the wing, without an airbag
being deployed. This is the case if only parts
which are relatively easily deformed are affec- ted and the rate of deceleration is not high.
Conversely, airbags may be deployed even
though the vehicle suffers only minor defor-
mation. This is the case if, for example, very
rigid vehicle parts such as longitudinal body
members are hit, and sufficient deceleration
occurs as
aresult. Airbags
Important safety notes Airbag deployment slows down and restricts
the movement of the vehicle occupant.
If the airbags are deployed, you will hear a
bang and asmall amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The 6SRS warning lamp
lights up.
The airbag installation locations are identified
by the AIRBAG symbol. G
WARNING
Airbags provide additional protection; they
are not, however, asubstitute for seat belts.
Observe the following notes to reduce the risk
of serious or even fatal injury caused by airbag
deployment:
R All vehicle occupants –inparticular ,preg-
nan twome n–m ust wear their seat belt
correctly at all times and lean back against
th eb ackrest, whic hshoul dbep ositioned
as close to th evertical as possible. The
head restraint must support th eback of the
head at about eye level.
R Always secure childre nless than 1.50mt all
and unde r12years of age in suitable child
restraint systems.
R All vehicle occupant smust select aseat
position that is as far away from the airbag
as possible. The driver's seat position must
allow the vehicle to be driven safely. The
driver's chest should be as far away from 40
Occupant safetySafety

Example: the passenge
ronthe right rear seat has
their seat belt fastened.
You can also cancel the rear seat belt status
indicator immediately (Y page 232).
i The status indicator for the rear-compart-
ment seat belts is only available for certain
countries.
Belt tensioners, belt force limiters The seat belts are fitted with belt tensioners.
The belt tensionerst ighten the seat belts in
an accident, pulling them close against the
body.
Belt tensionersdon ot correct incorrects eat
positions or incorrectly fastened seat belts.
Belt tensionersdon ot pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with abelt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupant is
reduced.
The belt force limiters for the front seats are
synchronised with the front airbags. These
take on apart of the deceleration force. Thus,
the force exerted on the occupant is distrib-
uted over agreater area.
The belt tensionersc an only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 39).
R the belt tongue is engaged in the buckle on
each of the three-point seat belts in the
front.
The belt tensionersont he seats in the rear
compartmenta re triggeredindependently of
the lock status of the seat belts. The beltt
ensioners are triggered depending
on the type and severit yofanaccident:
R if, in the event of ahead-on or rear-en dcol-
lision, the vehicle decelerates or acceler-
ates rapidly in alongitudinal direction dur-
ing the initial stages of the impact
R if, in the event of aside impact, on the side
opposite the impact the vehicle deceler-
ates or accelerates rapidly in alateral direc-
tion
R Cabriolet: in certain situation sifthe vehicle
overturns and the system determines that
it can provide additional protection.
If the airbags are deployed, you will hear a
bang, and asmall amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The 6SRS warning lamp
lights up. G
WARNING
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at aqualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners .Any Mercedes-Benz
Service Centr ecan provide details of these
regulations.
! If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident. 50

checked at aqualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. acushion, under the child
restraint system. The entire base of the child
restraint system must alwaysr est on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-
tive function in the event of an accident, and
could leadtoi njuries.

R mobile phones
R cards with transponders, e.g. ski passes or
access cards
Signals from electronic equipment can cause
interference in the automatic child seat rec-
ognition sensor system. This can lead to a
system malfunction. This may cause the
4 PASSENGER AIRBAG OFF indicator
lamp to light up without there being achild
seat with transponders for automatic child
seat recognition fitted. The front-passenger
airbag will not then deploy during an accident.
It is also possible that the 6SRS warning

lock to position 2.
ISOFIXc hild seat securing system for
the rear seats ISOFIXisas
tandardised securing system for
specially designed child restraint systems on
the rear seats. Securing rings for two ISOFIX
child restraint systems are fitted on the left
and right of the rear seats.
Mercedes-Ben zrecommends the use of ISO-
FIX child restraint systems listed on
(Y page 59) together with the insertion
guides included. Using insertion guides
makes it easier to fit ISOFIXc hild restraint
systems. G
WARNING
Ac hild restraint system secured by the ISOFIX
child seat securing system does not provide
sufficient protection for children weighing
more than 22 kg. For this reason, do not
secure children weighing more than 22 kg in
ac hild restraint system secured by the ISOFIX
child seat securing system. If the child weighs
more than 22 kg, secure the child restraint
system using athree-point seat belt. G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to as uitable vehicle seat. The child cannot be
restrained in the event of an accident, heavy
braking or sudden changes of direction. The
child could be seriously or even fatally injured.
For this reason, when fittingac hild restraint
system, observe the manufacturer's installa-
tion instructions and the correct use of the
child restraint system.
For reasons of safety, only use child restraint
systems with the ISOFIX child seat securing
system on the rear seats.
We recommendt hat you use the ISOFIX child
restraint systems that have been recommen-
ded for Mercedes-Benz. 54
