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. However, 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 (e.g. a collision in which the noise 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 the safety of all occupants, be sure to
always wear 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 frontal
collision.The SRS airbag system mainly consists
of the following components and their
locations are shown in the illustration.
1. Steering wheel pad (airbag and inflat-or)
2. Airbag sensor assembly.
3. SRS airbag warning light.
4. Passenger airbag module (airbag and inflator)
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 air-
bags with non-toxic nitrogen gas to help
restrain the forward motion of the occu-
pants.
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
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.

Do not modify, remove or open any
components or wiring, such as the
steering wheel column cover, front
passenger airbag cover, front pas-
senger airbag, airbag sensor as-
sembly. Doing any of these may
cause sudden SRS airbag inflation
or disable the system, which could
result in personal injury.
Failure to follow these instructions
can result serious injuries.
Do not perform any of the following changes without consulting your
Toyota dealer. Such changes caninterfere with proper operation ofthe SRS airbag system in somecases.
Installation of electronic itemssuch as a mobile two-way radio,
cassette tape player or compactdisc player
Modification of the suspension
system
Modification of the front endstructure
Attachment of a grille guard (bullbar, kangaroo bar, etc.), snow-
plow, winches or any other equip-ment to the front end
Repairs made on or near the frontend structure, console, steeringcolumn, steering wheel or dash-board near the front passenger
airbag
NOTICE
This SRS airbag system has a service re-
minder indicator to inf orm the driver of op-
erating problems. If either of the following

NOTICE
Do not drive the vehicle with the warning light onÐeven for one
block. It may ruin the engine.
(e) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty.
(See Fuel gaugeº in Chapter 1-5 for in-
structions.)
b. The fuel tank cap is not tightened se-
curely. (See Fuel tank capº in Chapter
1-2 for instructions.)
c. There is a problem somewhere in
your engine or automatic transmission
electrical system.
If it comes on while you are driving in case
c, have your vehicle checked/repaired by
your Toyota dealer as soon as possible.
(f) Low Fuel Level Warning Light
This light comes on when the fuel level in
the tank becomes nearly empty. Fill up
the tank as soon as possible. (g) ABSº Warning Light
This light warns that there is a problem
somewhere in your anti-lock brake sys-
tem.
If the light comes on while you are driving,
have your vehicle checked by your T
oyota
dealer as soon as possible.
The light will come on when the ignition
key is turned to the ONº position. After
about 3 seconds, the light will go off.
When the ABSº warning light is on (and
the brake system warning light is off), the
brake system operates conventionally but
anti-lock brake system is not assisting
brake performance so that the wheels can
lock-up during sudden braking or braking
on slippery road surfaces.
(h) Open Door Warning Light
This light remains on until all the doors are
completely closed.
(i) Rear Light Failure Warning Light
If this light comes on when the headlight
switch is turned on (at the position 1 or
position 2), it indicates that one or more of
the tail lights are burned out.
If it comes on when the brake pedal is de-
pressed, one or more stop lights are
burned out. Have
defective bulbs replaced as soon as
possible.
(j) SRS Airbag Warning Light
This light will come on when the igni-
tion key is turned to the ACCº or ONº
position. After about 6 seconds, the
light w ill go off. This means the airbag
system is operating properly.
The warning light system monitors airbag
sensor assembly, inflators, warning light,
interconnecting wiring and power
sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota 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.
