recommend that you adjust the passenger's seat
in the following manner:
.,. Bring the backrest up to an (a lmost) upright
position .
Do not ride with the seat reclined.
.,. Applies to vehicles with adjustable head re­
straints: Adjust the head restra int so the upper
edge is as even as poss ible with the top of your
head. If that is not possible, try to adjust the
head restraint so that it is as close to th is posi­

with the backrest reclined. Safety belts and
the airbag system only offer maximum pro­
tect ion when the backrest is upr ight and the
safety belts are properly positioned on the body. T he more the backrest is reclined, the
greater the risk of pe rsonal inj ury from an
