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
R Child restraint system
R Child seatsecuring systems 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 42)
R have theseat andhead restraint adjusted
properly (Ypage 92)
As the driver, youalso have tomake surethat
the steering wheelisadjusted correctly.
Observe theinformation relatingtothe correct
driver's seatposition (Ypage 92).
You also have tomake surethatanair bag can
inflate properly ifdeploye d(Y page 44).
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.
