Safety systems of your vehicle

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 based upon the severity of a col-

lision and its direction. These two fac-

tors determine 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. 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 the

extremely short time in which a collision

occurs and the need to position 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 col-

lision and is thus a necessary part of air

bag design.

However, air bag inflation can also

cause injuries which include facial

abrasions, bruises and broken bones,

and sometimes more severe injuries

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 air bag

can cause fatal injuries, especially if

the occupant is positioned exces-

sively close to the air bag.
