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 (if
equipped with side air bag or curtain
air bag) in order to help protect the
occupants from serious physical 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 produce 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. The determining, factors are
not limited 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 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.
However, air bag inflation can also
cause injuries which can include facial
abrasions, bruises and broken bones
because the inflation speed also caus-
es 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.
WARNING
• To avoid severe personal injury
or death caused by deploying air
bags in a collision, the driver
should sit as far back from the
steering wheel air bag as possi-
ble (at least 250 mm (10 inches)
away). The front passenger
should always move their seat as
far back as possible and sit back
in their seat.
• Air bag inflates instantly in an
event of a collision, passengers
may be injured by the air bag
expansion force if they are not in
a proper position.
• Air bag inflation may cause
injuries including facial or bodily
abrasions, injuries from broken
glasses or burns.
