Seating and Safety Restraints
135
When are the front air bags and
pretensioners deployed?
Front air bags and pretensioners
are designed to activate in frontal
and nearĆfrontal collisions, not
rollover, sideĆimpacts, or
rearĆimpacts unless the collision
causes sufficient longitudinal
deceleration. The fact that the
pretensioners or air bags did not
activate in a collision does not mean
that something is wrong with the
system. Rather, it means the
Personal Safety System determined
the occupant conditions or crash
severity were not appropiate to
activate these safety devices.
