Inflator and Bag for Front Passenger
1) General
The inflator and ag for front passenger are inserted inside the case, and located in the passenger side instrument panel.
the bag is made of strong nylon cloth, and becomes inflated by the argon gas flowed from the inflator. Also, 2 types
of the inflator for front passenger have been adopted: TRW made and Morton made.
2) Inflator of TRW Made
The inflator of TRW made is comprised of a squib, propellant grain, burst cup and high pressure argon gas.
If the airbag sensor is turned on by deceleration due to frontal collision, electric current then ignites the squib located
in the inflator. the frame of squib spreads instaneously to the propellant grain. If the internal pressure of the burst cup
increases by the combustion of the propellant grain, the burst cup will be released by making its bulkhead break. With
this, the gas which expanded by the tgeat of the ignition of the propellant grain flows into the airbag via the diffuser,
thus inflating the airbag.

4. Construction and Operation
Side Airbag Sensor Assembly
1) Description
The side airbag sensor assembly is mounted on the right and left center pillars. It receives signals from
the side airbag sensor enclosed in the side airbag sensor assembly and judges whether the side airbag must
be activated or not.
2) Construction and Operation
The side airbag sensor assembly consists of side airbag sensor, safing sensor, etc.
a. Side Airbag Sensor
The side airbag sensor is enclosed in the side airbag sensor assembly based on the acceleration of the
vehicle that occurs during a side collision. The distortion created in the sensor is converted into an elec-
tric signal. This signal is a linear representation of the acceleration rate.
b. Safing Sensor
The safing sensor is enclosed in the side airbag sensor assembly. The sensor turns ON if an acceleration
force that is higher than a predetermined value is applied to the safing sensor as a result of a side colli-
sion.
Airbag Sensor Assembly
1) Description
The airbag sensor assembly is mounted on the center floor under the instrument panel.
When the airbag sensor assembly receives the airbag activation signal from the side airbag sensor assem-
bly, it applies current to the inflator.
Furthermore, the airbag sensor assembly diagnoses a system malfunction of the side airbag system.
This is the same airbag sensor assembly that is used for the
SRS airbag for the driver and front passenger.
2) Construction and Operation
The airbag sensor assembly consists of ignition control circuit, back up power source, diagnosis circuit,
memory circuit, etc.
a. Ignition Control Circuit
The ignition control circuit performs a prescribed calculation based on the signal output by the airbag
sensor and the front airbag sensor. If these calculated values are larger than a predetermined value, it
activates the ignition operation.
b. Back-Up Power Source
The back-up power source consists of a back-up capacitor and a DC-DC converter. In case of a power
system failure during a collision, the back-up capacitor discharges and supplies electric power to the
system. The DC-DC converter is a boosting transformer when the battery voltage drops below a certain
level.
c. Diagnosis Circuit
This circuit constantly diagnoses the system for any malfunction. When a malfunction is detected, it
lights up the
SRS warning light on the combination meter to alert the driver.
d. Memory Circuit
When a malfunction is detected by the diagnosis circuit, it is coded and stored in this memory circuit.

CAUTION
The SRS side airbags are installed in
the driver and front passenger seats.
Observe the following precautions.

Do not lean against the front door
when the vehicle is in use. The side
airbag inflates with considerable
speed and force; you may be killed
or seriously injured.

Do not modify or replace the seats
or surface of the front seats with
the side airbags. Such changes may
disable the system or cause the
side airbags to inflate, resulting in
death or serious injury. Consult
your Toyota dealer.

Do not use accessories for the
seats which cover the parts where
the side airbags should inflate.
Such accessories may prevent the
side airbags from activating correct-
ly, causing death or serious injury.
Adjust the driver's seat so that the foot
pedals, steering wheel and instrument
panel controls are within easy reach of
the driver.
CAUTION

Adjustments should not be made
while the vehicle is moving, as the
seat may unexpectedly move and
cause the driver to lose control of
the vehicle.

When adjusting the seat, be careful
not to hit the seat against a pas-
senger or luggage.

After adjusting the seat position,
try sliding it forward and backward
to make sure it is locked in posi-
tion.

After adjusting the seatback, exert
body pressure to make sure it is
locked in position.

Do not put objects under the seats.
The objects may interfere with the
seat±lock mechanism or unexpect-
edly push up the seat position ad-
justing lever; the seat may suddenly
move, causing the driver to lose
control of the vehicle.

While adjusting the seat, do not put
your hands under the seat or near
the moving parts. You may catch
and injure your hands or fingers.

Position 1ÐParking, tail, license plate,
side marker and instrument panel lights
Position 2ÐHeadlights and all of the
above
The lights automatically turn off when the
driver 's door is opened with the ignition
turned off. To turn them on again, turn the
key to the ºONº position or actuate the
headlight switch. If you are going to park
for over one week, make sure the head-
light switch is off.
NOTICE
To prevent the battery from being dis-
charged, do not leave the lights on
for a long period when the engine is
not running.
Daytime running light system
The headlights turn on at reduced intensi-
ty when the parking brake is released with
the engine started, even with the light
switch in the ºOFFº position. They will not
go off until the ignition switch is turned
off.
To turn on the other exterior lights and
instrument panel lights, twist the knob to
the position 1.
Twist the knob to the position 2 to turn
the headlights to full intensity for driving
at night.
The headlights automatically turn to full
intensity in the twilight even with the light
switch in the ºOFFº position.

The daytime running light control sensor
is on the top of the passenger 's side
instrument panel.
Do not place anything on the instrument
panel, and/or do not affix anything on the
windshield to block this sensor.High±Low beamsÐFor high beams, turn
the headlights on and push the lever away
from you (position 1). Pull the lever to-
ward you (position 2) for low beams.
The headlight high beam indicator light
(blue light) on the instrument panel will
tell you that the high beams are on.
Flashing the high beam headlights
(position 3)ÐPull the lever all the way
back. The high beam headlights turn off
when you release the lever.
You can flash the high beam headlights
with the knob turned to ºOFFº.TURN SIGNALS
To signal a turn, push the headlight/
turn signal lever up or down to position
1.
The key must be in the ºONº position.
The lever automatically returns after you
make a turn, but you may have to return
it by hand after you change lanes.
To signal a lane change, move the lever
up or down to the pressure point (position
2) and hold it.
If the turn signal indicator lights (green
lights) on the instrument panel flash faster
than normal, a front or rear turn signal
bulb is burned out.

Emergency flashers
To turn on the emergency flashers,
push the switch.
All the turn signal lights will flash. To turn
them off, push the switch once again.
Turn on the emergency flashers to warn
other drivers if your vehicle must be
stopped where it might be a traffic hazard.
Always pull as far off the road as pos-
sible.
The turn signal light switch will not work
when the emergency flashers are operat-
ing.
NOTICE
To prevent the battery from being dis-
charged, do not leave the switch on
longer than necessary when the en-
gine is not running.
