CAUTION
A driver too close to the steering
wheel during airbag deployment can
be killed or seriously injured. Toyota
strongly recommends that: The driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.
All vehicle occupants be properly
restrained using the available seat
belts.
This indicator comes on when the igni-
tion key is turned to the ”ACC” or
”ON” position. It goes off after about
6 seconds. This means the SRS airbag
is operating properly.
The SRS airbag warning light system
monitors the front airbag sensors, center
airbag sensor assembly, inflator, warning
light, interconnecting wiring and power
sources.The SRS airbag system is designed to
activate in response to a severe frontal
impact within the shaded area between
the arrows in the illustration.
There may be the case that the SRS air-
bag will not activate with such an impact
in which the occupant wearing the seat
belt correctly would not get serious injury.
The SRS airbag 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
impacting 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 airbag
may not deploy.

T100(U)29
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
impact, or if it is involved in an underride
collision (e.g. a collision in which the nose
of the vehicle ”underrides”, or goes under,
the bed of a truck).
For the safety of all occupants, be sure
to always wear seat belts.
The SRS airbag is not designed to in-
flate 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 center airbag sensor assembly con-
sists of a safing sensor and center airbag
sensor.
In a severe frontal impact, the sensor de-
tects deceleration and the system triggers
the airbag inflator. Then a chemical reac-
tion in the inflator momentarily fills the
airbag with non-toxic gas to help restrain
the forward motion of the driver.
When the airbag inflates, it produces a
fairly loud noise and releases some
smoke along with non-toxic gas. This does
not indicate a fire. Be sure to wash off
any residue as soon as possible to pre-
vent minor skin irritation.

T100(U)31
Do not modify or remove any wir-
ing. Do not modify, remove, strike
or open any components, such as
the steering wheel column cover,
center airbag sensor assembly or
front airbag sensors. Doing any of
these may cause sudden SRS air-
bag inflation or disable the system,
which could result in death or seri-
ous injury.
Failure to follow these instructions
can result in death or serious inju-
ries.NOTICE
Do not perform any of the following
changes without consulting your Toy-
ota dealer. Such changes can interfere
with proper operation of the SRS air-
bag system in some cases. Installation of electronic items such
as a mobile two-way radio, cassette
tape player or compact disc player
Modification of the suspension sys-
tem
Modification of the front end struc-
ture
Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
Repairs made on or near the front
fenders, front end structure, con-
sole, steering column or steering wheel

This SRS airbag system has a service
reminder indicator to inform the driver of
operating problems. If either of the follow-
ing conditions occurs, this indicates a mal-
function of the airbag. 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 ”ACC” or
”ON” position, or remains on.
The light comes on while driving.

T100(U)63
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(e) 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.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.
(f) Malfunction indicator lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See
”Fuel gauge” in Chapter 1−5 for instruc-
tions.)
b. The fuel tank cap is not tightened se-
curely. (See ”Fuel tank cap” in Chapter1 −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 b, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible.
(g) ”ABS” Warning Light
This light warns that there is a problem
somewhere in your anti-lock brake system.
If it comes on while you are driving, have
your vehicle checked by your Toyota dealer
as soon as possible.
The light will come on when the ignition
key is turned to the ”ON” position. After
about 3 seconds, the light will go off.
When the ”ABS” 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) SRS Airbag Warning Light
This light will come on when the ignition
key is turned to the ”ACC” or ”ON” posi-
tion. After about 6 seconds, the light will
go off. This means the airbag system is
operating properly. The warning light system monitors the
front airbag sensors, center airbag sensor
assembly, inflator, warning light, intercon-
necting 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 ”ACC” or
”ON” position or remains on.
The light comes on while driving.
(i) Light Reminder Buzzer
This buzzer will sound if the driver ’s door
is opened while the ignition switch is
turned to the ”LOCK” position with the
headlight switch on. Removing the key will
not stop the buzzer as long as the head-
light switch is on.
(j) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver’s door with
the ignition key in the ”ACC” or ”LOCK”
position.
