50 Safety
Occupant safety
Triggering ofbelt tensioners, belt force limiters and
airbags
In the event ofa collision, the sensor in the
airbag contro lunit evaluates important
physical data, such as duration, direction
and rate of veh icle deceleration or acceler-
ation. Based on this evaluation and pre-
emptively, the belt tensioners are the first
to be triggered by the airb agcontrol unit in
a collis ion with longi tudinal deceleration as
a function of the rate of vehicle decelera-
tion.
The front airbags are not triggered unless a
second activation threshold is reached, i.e.
an even higher rate of vehicle deceleration
in the longitudinal direction is exceeded. i
Thefront airbag on the front-passenger side
is only tri ggered if:
! the front-passenger seat oc cupancy sensor
has detected that the seat is occupied
! the PASSENGER AIRBAG OFF warning lamp
onthe centre console is not lit (
=page 64)
The belt tensioners are only activated if the seat
belt buck le tongue is correctl yengaged in the
se at belt buckle.
Criteria for the activation of belt
tensioners and airbags
To determine whether it is necessary to
activ ate a belt tensioner or airbag, the air-
bag control unit evaluates the duration and
direction of vehicle deceleration or accel-
eration during the initial phase of the colli-
sion.
The activation thresholds for the belt ten-
sioners and the airbags are variable and
are adapted in accordance with the rate of
ve hicle deceleration. This process ispre-
emptive in nature as airbag deployment
must take place during the impact and not
at the end of the collision. G
Risk of inju ry A malfu
nction has occurred if the 1
warning lamp:
! doesnot com eon when yousw itchon
th eignition
! does not go out after a few seconds
when the engine is running
! comes on again
Individ ual systems could beactivated inad-
verte ntly or may not be triggered at all in the
event of an accident with a high rate of vehi-
cle deceleration. Ifthis happens, have the
SRS system checked and repaired immedi-
ately at a qualified specialist wor kshop
wh ich has the necessary specialist know-
ledg eand tools to carry out the work
require d.
Mercedes-Benz recomme nds that youuse a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-re lated systems must be car-
ried out at a qualified specialist workshop. 209en_d2.boo Seite

Airbags ar enot activat edin all types of acci-
dent .The yare controlled by complex sensor
technology and evaluation logic .This ispre-emp-
tiv einnature since theairbag must beactivat ed
as the accident occurs and must be adap ted to
provide the cal culated, additional protection for
the vehicle occupants. Not all the airbags are
act ivated in an accident.
The various airbag sy stems operate independ-
ently .However, each sy stem is dependent on
the type of accident (frontal /side /rear impact
and overturning) and severity of th eaccident
(mainly vehicle deceleration or acc eler ation)
predicted during the initial phase of the accident.
Vehicle deceleration or acceleration and
force direction are essentially determined
by:
! the distribution of forces during the
collision
! the collision angle !
the deformation characteristics of the
vehicle
! the characteristi csofthe other object
in volved in the collision, e.g. the other
ve hicle
Factors which can only be seen and meas-
ured after the collision has taken place do
not play a dec isive role in the deployment
of an airbag, nor do they provide an indica-
tion of it.
The vehicle may be substantia lly deformed
wi thout an airbag being triggered, e.g. if
only relatively easi ly-deformable vehicle
parts such as the bonnet or wings are
affected by the collision and the required
deceleration threshold isnot reached. On
the other hand, airbags may be triggered
even though the vehicle only displays
minor deformation, if rigid vehicle parts,
for example, longitud inal membe rs, are
af fe cted by theimpact, causing vehicle
deceleration to exceed the pre-determined
threshold. Belt tensioners, belt force limiters
The front seat belts are equipped with:
!
Belt tensioners
! Belt force limiters
! An autom atic comf ort-fit feature
The rear seat belts are equipped with: ! Belt tensioners
! Belt force limiters
! Do not insert the belt tongue into the front-
passenger seat belt buckle if the front-passenger
seat is unocc upied. The belt tensioner could oth-
erw ise be trigg ered in theevent ofan accident.
Be lttensioners tension the seat belts inan

Occupant safety
The purpose of triggering sidebags is to
increase the level of protection for the tho-
rax (but not the head, neck or arms) of
occupants affected by the impact. The
sidebags are installed in the middle of the
doors and in the sidewa llin the rear. The
locations in which the sidebags in your
ve hicle are fitted are identified by the
SRS /AIRBAG label on each of these areas.
1 Front sidebag
2 Rea rsidebag
3 Windowbag The sid
ebag inflates in the door area below
the window.
The sidebags are triggered:
! on the side on which an impact occurs
! inthe first stages of an accident with
high lateral forces of vehicle decelera-
tion or acceleration, e.g. a side impact
! ifthe system foresees that airbag
deployment can offer additional pro-
tection to that provided by the seat belt
! depending on the use of the seat belt
! independently of the front airbags
! independently of the belt tensioners
! rarely if the vehicle overturns, unless
high forces of vehicle deceleration ina
lo ngitudinal direction are detected and
it is predi cted that airbag inflation will
prov ide additional protection to that of
the seat belt i
Inthe eve ntofan imp act on the front-pas-
senger side, the front-passenger sidebag is only
triggered if:
! the front -pas se nger seat occupancy sensor
ha s detecte dthat the seat is occ upied
The rear sidebag on the driver's side is triggered
in conjun ction wit hthe driver's sidebag.

Rearward-facing child seat warning symbol Automat
icchild seat rec ognition
The sensor system for the front-passenger
seat automatical lyrecognises whether a
special Mercedes-Benz rearward-facing
chi ldseat is fitted. If this is the case, the
PASSEN GER AIRBAG OFF warning lamp on
the centre console lights up. G
Risk of inju ry A rearward-faci
ngchild restraint system
must not be used on a seat protected by an
ai rbag install edinfront ofthe seat unless
the airbag is deactivated. To make this clear,
an appropriate warning sticker is affixed to
either side of the front-passenger sun visor. G
Risk of inju ry A rearward-faci
ngchild restraint system
must not be used on a seat protected by an
ai rbag install edinfront ofthe seat unless
the airbag is deactivated.
On the front-pass enger seat, only use child
restraint systems with automatic child seat
recognition which have been recommended
for Mercedes-Be nzvehicl es. You can obt ain
information from any Mercedes-Benz Serv-
ice Centre.
If yo u usearearward-facing child seat on
the front-passenger seat, it must be a spe-
cial Mercedes-Be nzrearward- facing child
seat with automatic ch ild seat recognition. If other rearward-facing child seats are used
on th efront-passenger seat, the front-pas-
senger airbag is not deactivated and the
child could be seriously or fatally injured by
the airb aginflating. To makethis clear,an
appropriate warning symbol is affixed in the
cockpit.
If you use a forward-facing child seat with-
out automatic child seat recognition on the
fr ont-passenger seat, you must move the
fr ont-passenger seat to its rearm ostp osi-
tion.
Do not leave children unsupervised in the
vehi cle, even if they are sec ured in a child
restraint syst em. They would otherwise be
unable to res cue them selves if danger
threatens ,e.g.ex ces sive heat. Or the ycould
oth erwi se be injured by moving parts in the
vehic le, such as seats, or open the doors
and th ereby endanger themselves and oth-
ers, for example. 209en_d2.boo Seite
