The SRS (Supplemental Restraint Sys-
tem) airbags are designed to provide
further protection to the driver and
front passenger when added to the pri-
mary protection provided by the seatbelts.
In response to a severe frontal impact, the
SRS airbags work together with the seat
belts to help preventing or reduce injury by
inflating, in order to decrease the likeli-
hood of the driver's or front passenger's
head or chest directly hitting the steering
wheel or dashboard. The passenger air-
bag is activated even with no passenger
in the front seat.This indicator comes on when the
ignition key is turned to the ACCº or
ONº position. It goes off after about 6
seconds. This means the SRS airbags
are operating properly.
The SRS airbag warning light system
monitors the airbag sensor assembly, in-
flators, warning light, interconnecting wir-
ing and power sources.The SRS airbag system is designed to
activate in response to a severe frontal
impact within the shaded area be-
tween the arrows in the illustration.
The SRS airbags will deploy if the severity
of the impact is above the designed
threshold level, comparable to an approxi-
mate 20 km/h (14 mph) collision when im-
pacting straight into a fixed barrier that
does not move or deform.
If the severity of the impact is below the
above threshold level, the SRS airbags
may not deploy.

30However, this threshold velocity will be
considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign
pole, which can move or deform on im-
pact, or if it is
involved in an underride col-
lision (a collision in which the nose of the
vehicle underridesº, or goes under, the
bed of a truck.) It is possible with collision severity at the marginal level of airbag sensor detection
and activation that only one of your ve-
hicle's two airbags will deploy.
For your safety, be sure to always wear your seat belts.
The SRS airbags are not designed to inflate if the vehicle is subjected to a
side or rear impact, if it rolls over, or if
it is involved in a low-speed frontalcollision.The SRS airbag system mainly consists
of the following components and their
locations are shown in the illustration.
1. SRS airbag warning light
2. Steering wheel pad (airbag and inflat-
or)
3. Passenger airbag module (airbag and inflator)
4. Airbag sensor assembly
The airbag sensor assembly consists of a
safing sensor and airbag sensor.

In a severe frontal impact, sensors detect
deceleration and the system triggers the
airbag inflators. Then a chemical reaction in
the inflators momentarily fills the airbags
with non- toxic nitrogen gas to help restrain
the forward motion of the occupants.
When the airbags inflate, they produce a
fairly loud noise and release some smoke
along with the nitrogen gas. This is not
harmful and does not indicate a fire. Be sure
to wash off any residue as soon as possible
to prevent minor skin irritation.
Deployment of the airbags happen in a frac-
tion 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 swellings.
Parts of the airbag module (steering wheel
hub, dashboard) 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 air-
bags may break the windshield as the ve-
hicle buckles. In vehicles with a passenger
airbag the windshield may also be dam-
aged by absorbing some of the force of the
inflating airbag.
CAUTION!
The SRS airbag system is designed
only as a supplement to the prima-
ry protection of the seat belt sys-
tems of the driver and front passen-
ger. The front seat occupants are
particularly susceptible to injury if
they do not wear their seat belts;
when sudden braking or a collision
occurs, they may be thrown for-
ward. To obtain maximum protec-
tion in an accident, the driver and
all passengers in the vehicle
should always wear their seat belts
when driving because serious in-
juries can result to unrestrained
occupants. For instructions and
precautions concerning the seat
belt system, see Seat beltsº in this
chapter.
A baby or small child who is too
small to use a seat belt should be
properly secured in a rear seat us-
ing a child restraint system.
Never put a rear-facing child re-
straint system in the front seat be- cause the force of the rapid infla-
tion of the passenger airbag can cause severe injury to the child.
