air bags inflate at a level less
than full deployment.
For more severe froniat Impacts, full deployrreni occurs.
ÍÍ thfl froni of your vehrde goes siraighi into a wall

deploy mont is about 1É to 2S mph (26 to AO km/h).
The threshold levetcan vary, however, with specific
vehicle design, so that il cart be somewhat above
or below this range.

be higher. The diver's and right front passenger's frontal
