The restraint systemcanreduce therisk of
vehicle occupants comingintocontactwith

R have theseat andhead restraint adjusted
properly (Ypage 97)
As the driver, youalso have tomake surethat
the steering wheelisadjusted correctly. Observe
theinformation relatingtothe correct
driver's seatposition (Ypage 97).

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-
