DISPOSAL
HINT:
When scrapping vehicle equipped with an SRS or disposing of
a front passenger airbag assembly, always first deploy the air-
bag in accordance with the procedure described below. If any
abnormality occurs with the airbag deployment, contact the
SERVICE DEPT. of TOYOTA MOTOR SALES, U.S.A., INC.
CAUTION:
Never dispose of a front passenger airbag assembly
of which airbag has not been deployed.
The airbag produces a sizeable exploding sound
when it deploys, so perform the operation out of
doors and where it will not create a nuisance to
nearby residents.
When deploying the airbag, always use the specified
SST (SRS Airbag Deployment Tool). Perform the op-
eration in a place away from electrical noise.
SST 09082-00700
When deploying an airbag, perform the operation at
least 10 m (33 ft) away from the front passenger air-
bag assembly.
The front passenger airbag assembly is very hot
when the airbag is deployed, so leave it alone for at
least 30 minutes after deployment.
Use gloves and safety glasses when handling a front
passenger airbag assembly with deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a front passenger airbag
assembly with deployed airbag.
1. AIRBAG DEPLOYMENT WHEN SCRAPPING VE-
HICLE
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Check the function of the SST
(See page RS-20).

(b) Disconnect the airbag connector.
(1) Remove the glove compartment door.
(2) Remove the No. 1 under cover.
NOTICE:
When handling the airbag connector, take care not to dam-
age the airbag wire harness.
(3) Pull up the connector.
(4) Disconnect the airbag connector.
(c) Install the SST.
(1) Connect the connector of SST to the front passen-
ger airbag assembly connector.
SST 09082-00700, 09082-00780
NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock.
(2) Move the SST at least 10 m (33 ft) away from the
front of the vehicle.
(3) Close all the doors and windows of the vehicle.
NOTICE:
Take care not to damage the SST wire harness.
(4) Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip to the negative (+)
terminal.
(d) Deploy the airbag.
(1) Check that no one is inside the vehicle, nor within
10 m (33 ft) area around the vehicle.
(2) Press the SST activation switch and deploy the air-
bag.
CAUTION:
The front passenger airbag assembly is very hot
when the airbag is deployed, so leave it alone for at
least 30 minutes after deployment.

Use gloves and safety glasses when handling a front
passenger airbag assembly with deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a front passenger airbag
assembly with deployed airbag.
When scrapping a vehicle, deploy the airbag and
scrap the vehicle with the front passenger airbag as-
sembly still installed.
When moving a vehicle for scrapping which has a
front passenger airbag assembly with deployed air-
bag, use gloves and safety glasses.
HINT:
The airbag deploys as the LED of the SST activation switch
comes on.
2. DEPLOYMENT WHEN DISPOSING OF FRONT PAS-
SENGER AIRBAG ASSEMBLY ONLY
NOTICE:
When disposing of the front passenger airbag assem-
bly only, never use the customer's vehicle to deploy
the airbag.
Be sure to follow the procedure given below when de-
ploying the airbag.
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Remove the front passenger airbag assembly
(See page RS-31).
CAUTION:
When removing the front passenger airbag assembly,
work must be started 90 seconds after the ignition
switch is turned to the ºLOCKº position and the nega-
tive (-) terminal cable is disconnected from the bat-
tery.
When storing the front passenger airbag assembly,
keep the upper surface of the airbag deployment side
facing upward.

(b) Using a service-purpose wire harness for the vehicle, tie
down the front passenger airbag assembly to the tire.
Wire harness: Stripped wire harness section
1.25 mm
2
or more (0.0019 in.2 or more)
CAUTION:
If a wire harness which is too thin or some other thing is
used to tie down the front passenger airbag assembly, it
may be snapped by the shock when the airbag is deployed.
This is highly dangerous. Always use a wire harness which
is at least 1.25 mm
2 (0.0019 in.2).
HINT:
To calculate the square of the stripped wire harness section:
Square = 3.14 X (Diameter)
2 divided by 4
(1) While passing the wire harness through the installa-
tion holes indicated by arrows in the illustration,
wind the wire harness around the tire.
(2) Position the front passenger airbag assembly in-
side the tire with the airbag deployment side facing
inside.
Tire size: Must exceed the following dimensions-
Width: 185 mm (7.28 in.)
Inner diameter: 360 mm (14.17 in.)
CAUTION:
Make sure that the wire harness is tight. It is very dan-
gerous if looseness in the wire harness results in the
front passenger airbag assembly coming free due to
the shock from the airbag deployment.
Always tie down the front passenger airbag assembly
with the airbag deployment side facing inside.
NOTICE:
The tire will be marked by the airbag deployment, so use a
redundant tire.

(c) Check the functioning of the SST
(See step 1-(a) on page RS-20).
SST 09082-00700
(d) Place tires.
(1) Place at least 2 tires under the tire to which the front
passenger airbag assembly is tied.
(2) Place at least 2 tires over the tire to which the front
passenger airbag assembly is tied. The top tire
should have the wheel installed.
(3) Tie the tires together with 2 wire harnesses.
CAUTION:
Make sure that the wire harnesses are tight. It is very dan-
gerous if loose wire harnesses result in the tires coming
free due to the shock from the airbag deploying.
HINT:
Place the SST connector and wire harness inside tires. Provide
at least 1 m (3 ft) of slack for the wire harness.
(e) Install the SST.
Connect the connector of the SST to the front passenger
airbag assembly connector.
SST 09082-00700, 09082-00780
NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock. Also, se-
cure some slack for the SST wire harness inside the tires.
(f) Deploy the airbag.
(1) Connect the red clip to the battery positive (+) termi-
nal and the black clip to the battery negative (-) ter-
minal.
(2) Confirm that no one is within 10 m (33 ft) area
around the tire which the front passenger airbag as-
sembly is tied to.
(3) Press the SST activation switch and deploy the air-
bag.
HINT:
The airbag deploys as the LED of the SST activation switch
comes on.
