This indicator comes on when the ignition key is
turned to the ªACCº or ªONº position. It goes off
after about 6 seconds. This means the front seat
belt pretensioners are operating properly.
This warning light system monitors the airbag sensor
assembly, side airbag sensor assemblies, front airbag
sensors, inflators, seat belt pretensioner assembly,
warning light, interconnecting wiring and power sources.

warning buzzersº on page 63.)

4Airbag sensor assembly
The seat belt pretensioner system consists mainly of the
above components, and their locations are shown in the
illustration.
The seat belt pretensioner is controlled by the airbag
sensor assembly. The airbag sensor assembly consists
of a safing sensor and airbag sensor.
When a seat belt pretensioner is activated, an operating
noise may be heard and a small amount of smoke±like
gas may be released. This gas is harmless and does not
indicate that a fire is occurring.
Once the seat belt pretensioner has been activated, the
seat belt retractor remains locked.

after about 6 seconds. This means the SRS airbags
are operating properly.
The SRS warning light system monitors the airbag
sensor assembly, front airbag sensors, inflators,
warning light, interconnecting wiring and power sources.

The SRS airbag system consists mainly of the above
components, and their locations are shown in the
illustration.
The airbag sensor assembly consists of a safing sensor
and airbag sensors.
In a severe frontal impact, the driver and front passenger
airbag sensors detect deceleration and the system
triggers the front airbag inflators. In a severe side
impact, the side airbag sensor triggers the side airbag
inflator. Then a chemical reaction in the inflators quickly
fills the airbags with non±toxic gas to help restrain the
forward or lateral motion of the occupants.When the SRS operates, it produces a fairly loud noise
and release some smoke and residue along with
non±toxic gas. This does not indicate a fire. This gas is
normally harmless; however, for those who have
delicate skin, it may cause a minor skin irritation. Be
sure to wash off any residue as soon as possible to
prevent any potential skin irritation.
Deployment of the airbags happens in a fraction of a
second, so the airbags must inflate with considerable
force. While the system is designed to reduce serious
injuries, it may also cause minor burns or abrasions and
swelling.
Parts of the airbag module (steering wheel hub,
dashboard, front seats) may be hot for several minutes,
but the airbags themselves will not be hot. The airbags
are designed to inflate only once.
A crash severe enough to inflate the driver and front
passenger airbags may break the windshield as the
vehicle buckles. In vehicles with a front passenger
airbag, the windshield may also be damaged by
absorbing some of the force of the inflating airbag.
