1997 TOYOTA T100 sensor

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 front airbag sensors, inflat- ors, 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 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 airbag
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).
For the safety of all occupants, be sure to
always wear your 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 colli-sion.The center airbag sensor assembly con-
sists of a safing sensor and center airbag
sensor.
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 airbag
with non-toxic nitrogen gas to help re-
strain the forward motion of the driver. When the airbag inflates, it produces a fairly loud noise and releases 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 airbag happens in a
fraction of a
second, so the airbag must in-
flate with considerable force. While the
system is designed to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swellings.
The steering wheel hub may be hot for
several minutes, but the airbag itself will
not be hot. The airbag is designed to in-
flate only once.
CAUTION!
The SRS airbag system is designed
only as a supplement to the primary
protection of the seat belt system of
the driver. The driver is particularly susceptible to injury if he/she does
not wear his/her seat belt; when sud- den braking or a collision occurs, he/
she may be thrown forward. To ob-
tain a maximum protection in an ac-
cident, the driver and all passengers
in the vehicle should always wear
their seat belts when driving be- cause serious injuries can result to
unrestrained occupants. For instruc-
tions and precautions concerning
the seat belt system, see Seat beltsº
in this chapter.

CAUTION!
Do not put objects on the steering
wheel pad. They might restrict infla-
tion or cause serious injury as they
are projected rearward.
Do not modify, remove or open any
component or wiring, such as the
steering wheel, column cover, cen- ter airbag sensor assembly or front
airbag sensors. Doing any of these
may cause sudden SRS airbag infla-
tion or disable the system, which
could result in personal 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 can interfere with proper operation ofthe SRS airbag system in some cases.
Installation of electronic itemssuch as a mobile two-way radio,
cassette tape player or compactdisc player
Modification of the suspensionsystem
Modification of the front end
structure
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 nearthe frontfenders, the front end structure,
console, steering column or steer-
ing wheel
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.

NOTICE
Do not drive the vehicle with the warning light onÐeven 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.
(f) 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 electri- cal system.
If it comes on while you are driving in case
b, have your vehicle checked/repaired by
your Toyota dealer 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), thebrake system operates conventionally but
anti-lock brake system is not assistingbrake 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 ACCº or ONº 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 igni-
tion key is turned to the ACCº or ONº
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 isturned to the LOCKº 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 ACCº or LOCKº position.
