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
belt 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 airbag
is 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.

In a severe frontal impact, sensor detects
deceleration and the system triggers the
airbag inflator. Then a chemical reaction
in the inflator momentarily fills the airbags
with non-toxic nitrogen gas to help re-
strain the forward motion of the occu- pants. When the airbag inflates, they produce a fairly
loud noise and release some smoke
along with the nitrogen gas. This is notharmful 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 happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is designed to reduce serious inju-
ries, 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 them- selves w ill not be hot. The airbags are de-
signed 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 passen-ger airbag the windshield may also be
damaged by absorbing some of the force
of the inflating airbag.
CAUTION!
The SRS airbag system is de-
signed only as a supplement to
the primary protection of the driv-
er side aseat belt systems. The
driver is particularly susceptible
to death or serious injury if they
does not wear their seat belt;
when sudden braking or a colli-
sion occurs, they may be thrown
forward into the deploying SRS
aribag. To obtain a maximum
protection in an accident, the driv-
er and all passengers in the ve-
hicle should always wear their
seat belts when driving because
serious injuries can result to unre-
strained occupants. For instruc-
tions 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 use 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.

34
If you must use a forward-facing
child restraint system in the front seat, the seat must be moved as far
back as possible. For instructions
concerning the installation of a
child restratint system, see Child
restraintº in this chapter. Do not sit on the edge of the seat
or lean over the dashboard when
the vehicle is in use. The airbags
inflate with considerable speed
and force; you may be severely in-
jured. Sit up straight and well back
in the seat, and always use your
seat belt. Do not allow a child to stand up, or
to kneel on the front passenger
seat. The airbag inflates with con-
siderable speed and force; the
child may be severely injured.
Do not hold a child on your lap or in your arms. Use a child restraint
system in the rear seat. For in-
structions concerning the installa- tion of a child restraint system, see
Child restraintº in this chapter.

35
Do not put objects on or in front of
the dashboard or steering wheel
pad that houses the airbag sys-
tem. They might restrict inflation
or cause personal injury as they
are projected rearward.
Do not modify, remove or open
any component or wiring, such as
the steering wheel, column cover,
front passenger airbag, airbag
sensor assembly. Doing any of
these may cause sudden SRS air-
bag inflation or disable the sys-
tem, which could result in person-
al injury.
Failure to follow these instructions can result in severe injuries.
NOTICE
Do not perform any of the following changes without consulting your
Toyota dealer. Such changes caninterfere with proper operation ofthe SRS airbag system in some
cases.
Installation of electronic itemssuch as a mobile two-way radio,
cassette tape player or compact
disc player
Modification of the suspension system
Modification of the front endstructure
Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snow-plow winches or any other equip-
ment to the front end
Repairs made on or near the frontend structure, console, steering
column, steering wheel or dash-board near the front passengerairbag.
This SRS airbag system has a service re-
minder indicator to inf orm the driver of op-
erating problems. If either of the following
conditions occurs, this indicates a mal-
function of the airbags. Contact your To-
yota dealer as soon as possible to service
the vehicle. The light does not come on when the
ignition key is turned to the ACCº or
ONº position, or remains on.
The light comes on while driving.
