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.
When disposing of a front passenger airbag assembly with an
airbag deployed in a collision, follow the same procedure given
in step 1−(e) in ”DISPOSAL”.
CAUTION:
Never dispose of a front passenger airbag assembly
which has an undeployed airbag.
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.

(a) Check functioning of the SST. (See page RS−11 )
(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 SST connector to the front passengerairbag assembly connector.
SST 09082−00700
NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock.
(2) Move the SST to 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 SST red clip to the battery positive (+)terminal and the black clip to the negative (+) termi-
nal.
(d) Deploy the airbag. (1) Confirm that no one is inside the vehicle or within 10
m (33 ft) area around the vehicle.

(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 SST connector to the front passenger airbag
assembly connector.

(f) Deploy the airbag (1) Connect the SST red clip to the battery positive (+)terminal and the black clip to the battery negative
(−) terminal.
(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.
