As the driver, youalso have tomake surethat
the steering wheelisadjusted correctly. Observe
theinformation relatingtothe correct

You also have tomake surethatanair bag can
inflate properly ifdeploye d(Y page 43).
An airbag supplements acorrect lyworn seat

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-
