Function of therestraint system in an acci‐
dent
Howthe restraint system worksisdetermined by
theseverity of theimpact detected and thetype
of accident anticipated:
R
Frontal impact
R
Rear impact
R
Side impact
R
Rollover
The activation thresholds forthe components of
therestraint system aredetermined based on the
evaluationofthe sensor values measured at vari‐
ous points in thevehicle. This process is pre-
emptiveinnature. The triggering/deployment of
thecomponents of therestraint system should
take place in good time at thestart of thecolli‐
sion.
Factorswhich can only be seenand measured
afteracollision has occurredcannot playadeci‐
siverole in airbag deployment. Nordotheypro‐
vide an indication of airbag deployment.
The vehicle maybedeformed significantlywith‐
out an airbag being deployed. This is thecase if
onlyparts whichare relatively easilydeformed
areaffected and therateofvehicle deceleration
is nothigh. Conversely,anairbag maybe
deployedeventhough thevehicle suffers only
minor deformation. If very rigid vehicle parts such
as longitudinal membersare hit, forexample, this
mayresult in sufficiently highlevels of vehicle
deceleration.
Depending on thedetected deployment situation,
thecomponents of therestraint system can be
activated or deployedindependentlyofeach
other:
R
Emergency Tensioning Device:frontal impact,
rear impact,side impact
1)
,rollover
R
Driver'sairbag, co-driverairbag: frontal
impact
R
Side airbag: side impact
R
Windowcurtain airbag: side impact,rollover,
frontal impact
1)
Onlywhen thevehicle is equipped withaside
airbag or windowcurtain airbag.

WARNING Risk of burnsfromhot air bag
components
The air bag parts arehot afteranair bag has
been deployed.
#
Do nottouchthe air bag parts.
#
Have adeployedair bag replaced at a
qualified specialistworkshop as soon as
possible.
Foryour safetyand that of your passengers, it is
recommended that youhave thevehicle towedto
aqualified specialistworkshop afteranaccident.
Take this intoaccount,particularly if an Emer‐
gency Tensioning Device hasbeentriggered or an
airbag hasbeen deployed.
If theEmergency Tensioning Devicesare trig‐
geredoranairbag is deployed, youwill hear a
bang,and asmallamountofpowder mayalso be
released:
R
The bang will notgenerallyaffect your hear‐
ing.
R
In general,the powder released is nothazard‐
ous to healthbut maycause short-term
breathing difficulties to persons suffering
from asthma or other pulmonaryconditions.
Provided it is safetodoso, leave thevehicle
immediatelyoropen thewindowinorder to
prevent breathing difficulties.
