How does the air bag system
operate
• Air bags are activated (able to inflate if
necessary) only when the ignition
switch is turned to the ON or START
position.
• Air bags inflate instantly in the event of
serious frontal or side collision in order
to help protect the occupants from seri-
ous physical injury.
Also, the air bags inflate instantly in the
event of a rollover in order to help pro-
tect the occupants from serious physi-
cal injury.
• There is no single speed at which the
air bags will inflate.
Generally, air bags are designed to
inflate by the severity of a collision and
its direction. These two factors deter-
mine whether the sensors send out an
electronic deployment/inflation signal.
• Air bag deployment depends on a
number of factors including vehicle
speed, angles of impact and the densi-
ty and stiffness of the vehicles or
objects which your vehicle hits in the
collision. Though, factors are not limit-
ed to those mentioned above.
• The front air bags will completely
inflate and deflate in an instant.
It is virtually impossible for you to see
the air bags inflate during an accident.
It is much more likely that you will sim-
ply see the deflated air bags hanging
out of their storage compartments after
the collision.
• In order to help provide protection in a
severe collision, the air bags must
inflate rapidly. The speed of air bag
inflation is a consequence of the
extremely short time in which a collision
occurs and the need to get the air bag
between the occupant and the vehicle
structures before the occupant impacts
those structures. This speed of inflation
reduces the risk of serious or life-
threatening injuries in a severe collision
and is thus a necessary part of air bag
design.
Safety system of your vehicle
However, air bag inflation can also
cause injuries which normally can
include facial abrasions, bruises and
broken bones, and sometimes more
severe injuries because the inflation
speed also causes the air bags to
expand with a great deal of force.
• There are even circumstances
under which contact with the steer-
ing wheel air bag can cause fatal
injuries, especially if the occupant
is positioned excessively close to
the steering wheel.
