The restraint systemcanreduce therisk of
vehicle occupants comingintocontactwith
parts ofthe vehicle's interiorinthe event ofan
accident. Inthe event ofan accident, the
restraint systemcanalso reduce theforces to
which thevehicle occupants aresubjected.
The restraint systemincludes thefollowing
componen ts:
R Seat beltsystem
R Air bags
The componen tsof the restraint systemwork
in conj unction witheach other. Theycanonly
deploy theirprotect ivefunct ionif,at all times,
all vehicle occupants:
R have fastened theirseatbelts correct ly
(Y page 41)
R have theseat andhead restraint adjusted
properly (Ypage 85)
As the driver, youalso have tomake surethat
the steering wheelisadjusted correctly. Observe
theinformation relatingtothe correct
driver's seatposition (Ypage 85).
You also have tomake surethatanair bag can
inflate properly ifdeploye d(Ypage 43).
An airbag supplements acorrect lyworn seat
belt. Asanadditional safetydevice, theairbag
increases thelevel ofprotect ionforvehicle
occupants inthe event ofan accident. For
example, if,inthe event ofan accident, the
protect ionoffered bythe seat beltissufficient,
the airbags arenot deploye d.When anacci-
dent occurs, onlytheairbags thatincrease
protect ioninthat particular accidentsituation
are deploye d.However, seatbelts andairbags
generally donot protect againstobjectspene-
tratin gthe vehicle fromtheoutside.
Inform ationonrestraint systemoperation can
be found under "Triggering ofthe Emergen cy
Tensioning Devicesandairbags"
(Y page 50).

ClassificationSystem
(OCS)
Introduction The
Occupant Classification System(OCS)cat-
egorizes theperson inthe front -passenger
seat. Depending onthat result, thefront -
passenger frontairbag and front -passenger
knee bagareeither enabled ordeactivated.
The system doesnotdeactivate:
R the side impact airbag
R the headba g
R the Emergenc yTensioning Devices
Requirements To
be classified correctly,the front passenger
must sit:
R with theseat beltfastened correctly
R in an almost upright position withtheir back
agai nstthe seat backrest
R with their feetresting onthe floor, ifpossi-
ble
If the front passenger doesnotobserve these
conditions, OCSmayproduce afalse classifi-
cation, e.g.because thefront passenger:
R transfers theirweight bysupporting them-
selves onavehicle armrest
R sits insuch awaythat their weight israised
from theseat cushion
If you install achild restraint systemonthe
front -passenger seat,besure toobserve the
correct positioning ofthe child restraint sys-
tem. Never placeobjects underorbehind the child
restraint system,e.g.acushion. The
entire baseofthe child restraint systemmust
alwa ysrest onthe seat cushion ofthe front -
passenger seat.Thebackrest ofthe forward-
facing childrestraint systemmustlieasflat as
possible againstthe backrest ofthe front -
passenger seat.
The child restraint systemmustnottouch the
roof orbe subjected toaload bythe head
restraint. Adjusttheangle ofthe seat backrest
and thehead restraint positionaccordingly.
Only thencanOCS beguara nteed tofunction
correct ly.Always observe thechild restraint
