The restraint systemcanreduce therisk ofvehi-
cle occupants comingintocont actwith parts of
the vehicle's interiorinthe event ofan accident.
The restraint systemcanalso reduce theforces
to which vehicle occupants aresubjected during
an accident.
The restraint systemcomprises:
R Seat beltsystem
R Air bags
R Child restraint system
R Child seatsecuring systems
The componen tsof the restraint systemworkin
conj unction witheach other. Theycanonly
deploy theirprotect ivefunct ionif,at all times, all
vehicle occupants:
R have fastened theirseatbelts correct ly
(Y page 43)
R have theseat andhead restraint adjusted
properly (Ypage 91) As
the driver, youalso have tomake surethat
the steering wheelisadjusted correctly.
Observe theinformation relatingtothe correct
driver's seatposition (Ypage 91).
You also have tomake surethatanair bag can
inflate properly ifdeploye d(Y page 45).
An airbag supplements acorrect lyworn seat
belt. Asanadditional safetydevice, theairbag
increases thelevel ofprotect ionforvehicle
occupants inthe event ofan accident. Forexam-
ple, if,inthe event ofan accident, theprotect ion
offered bythe seat beltissufficient, theairbags
are not deploye d.When anaccident occurs,only
the airbags thatincrease protectioninthat par-
ticular accident situation aredeploye d.How-
ever, seatbelts andairbags generally donot
protect againstobjectspenetrat ingthe vehicle
from theoutside.

Introduction The

An airbag complements thecorrect lyfastened
seat belt. Itis no substitute forthe seat belt. The
air bag provides additional protection inappli -
cable accident situations.
Not allair bags aredeploy edinan accident. The
different airbag systems functionindepend-
ently fromoneanother (Ypage 52).
However, nosystem available today cancom-
pletely eliminate injuriesandfatalities.
It is also notpossible torule outarisk ofinjury
caused byan air bag due tothe high speed at
which theairbag must bedeploy ed.
