Restraint system functionality
Whenthe ignition is switched on, a self-test isperformed, during whichtheurestraint sys‐temwarning lamp lights up. It goes out no laterthan afew seconds afterthevehicle isstarted.The components oftherestraint system arethenfunctional.
Malfunctioningrestraint system
A malfunction has occurred intherestraint sys‐tem if:
Rtheurestraint systemwarning lamp doesnot light up whenthe ignition is switched on
Rtheurestraint systemwarning lamplights up continuously orrepeatedly during ajourney
&WARNINGRisk of injuryorfatal injuryduetoa malfunction intherestraint sys‐tem
Iftherestraint system is malfunctioning,restraint system components may be trig‐
gered unintentionally or might not be trig‐gered at all intheevent of an accident. Thismay affectthe EmergencyTensioning Deviceor airbag,forexample.
#Havetherestraint systemchecked andrepaired immediately at aqualified spe‐cialistworkshop.
Function oftherestraint system in an acci‐dent
Howtherestraint systemworks is determinedbythe severity ofthe impact detected andthe typeof accident anticipated:
RFrontal impact
RRear impact
RSide impact
RRollover
The activationthresholdsforthe components oftherestraint system are determined based ontheevaluation ofthe sensorvalues measured atvarious points inthevehicle. This process is pre-emptive in nature. The triggering/deployment of
the components oftherestraint system musttakeplace in good time atthestart ofthe colli‐sion.
Factors whichcan only be seen and measuredafter a collision has occurred do not play a deci‐siverole inthe deployment of an airbag.Nordotheyprovide an indication of airbag deployment.
Thevehicle may be deformed significantly with‐out an airbag being deployed. This isthe case ifonly parts which arerelatively easily deformedare affected andtherateofvehicle decelerationis not high. Conversely, an airbag may bedeployedeventhoughthevehicle suffersonlyminor deformation. Ifveryrigidvehicle partssuch as longitudinal members are hit,forexam‐ple,this mayresult in sufficiently high levels ofvehicle deceleration.

RThe front passenger seat has been movedasfar back as possible.
RThe person is seated correctly.
#Ensure, bothbefore and duringthe jour‐ney,thatthestatus ofthe frontpassenger airbag is correct.
Ifthe front passenger seat is occupied,the clas‐sification ofthe person orchildrestraint systemonthe front passenger seattakes place afterthefront passenger front airbag shutoff self-test.ThePASSENGER AIRBAG indicator lamps dis‐playthestatus ofthe front passenger front air‐bag.
Always observethe notes onthe function ofthePASSENGER AIRBAG indicator lamps(→page 43).
Function ofthePASSENGER AIRBAG indica‐tor lamps
Self-testof automatic front passenger frontairbag shutoffWhenthe ignition is switched on, a self-test isperformed during whichthe twoPASSENGERAIRBAG ON and OFF indicator lamps light upsimultaneously.
Thestatus ofthe front passenger front airbag isdisplayed afterthe self-test:
RPASSENGER AIRBAG ON lights upfor60 seconds, subsequently bothindicatorlamps are off (PASSENGER AIRBAG ON andOFF):the front passenger front airbag is abletodeploy intheevent of an accident.
RPASSENGER AIRBAG OFF lights up continu‐ously:the front passenger front airbag is dis‐abled. It willthen not be deployed intheevent of an accident.
IfthePASSENGER AIRBAG ON indicator lamp isoff, onlythePASSENGER AIRBAG OFF indicatorlamp shows thestatus ofthe front passengerfront airbag. ThePASSENGER AIRBAG OFF indi‐cator lamp may be lit continuously or be off.
IfthePASSENGER AIRBAG OFF indicator lampandtheurestraint systemwarning lamplight up simultaneously,the front passenger seatmay not be used. Also inthis case, do not installachildrestraint system onthe front passengerseat. Haveautomatic front passenger front air‐bag shutoffchecked andrepaired immediately ataqualified specialistworkshop.

#Always observethechildrestraint sys‐tem manufacturer's installation instruc‐tions.
When installing achildrestraint system onthefront passenger seat, observethevehicle-spe‐cific information (→page57).
If a person is sitting onthe front passengerseat:PASSENGER AIRBAG OFF may be lit con‐tinuously or be off, depending onthe person'sstature.
A person onthe front passenger seat mustalways observethefollowing information:
RIfthe front passenger seat is occupiedbyanadult or a person with astature correspond‐ingtothat of an adult,thePASSENGER AIRBAG OFF indicator lamp must be off. Thisindicatesthatthe front passenger front air‐bag is enabled.
IfthePASSENGER AIRBAG OFF indicatorlamp is lit continuously,an adult or person
with a build correspondingtothat of an adultshould not usethe front passenger seat.Instead,theyshould use arear seat.
RIfthe front passenger seat is occupiedby aperson of smallerstature (e.g. ateenager orsmall adult),thePASSENGER AIRBAG OFFindicator lamp either lights up continuouslyorremains off, depending ontheresult oftheclassification.
-IfthePASSENGER AIRBAGOFF indicatorlamp is off: movethe front passengerseat asfar back as possible orthe personof smallerstature should use arear seat.
-IfthePASSENGER AIRBAGOFF indicatorlamp is lit continuously:the person ofsmallerstature should not usethe frontpassenger seat.
&WARNINGRisk of injuryor death whenthePASSENGER AIRBAG OFF indicatorlamp is lit
IfthePASSENGER AIRBAG OFF indicatorlampremains lit afterthe system self-test,the front passenger air bag is deactivated. It
will not be deployed intheevent of an acci‐dent. Inthis case,the front passenger air bagcannotperformits intended protective func‐tion, e.g. when a person is seated inthe frontpassenger seat.
That person could,forexample, come intocontact withthevehicle interior, especially ifthe person is sittingtoo closetothe cockpit.
Ifthe front passenger seat is occupied,always ensurethat:
RThe classification ofthe person inthefront passenger seat is correct andthefront passenger air bag is enabled ordeactivated in accordance withthe per‐son inthe front passenger seat.
RThe person is seated properly with a cor‐rectlyfastened seat belt.
RThe front passenger seat has been movedasfar back as possible.
