DISPOSAL

HINT:
When scrapping vehicles equipped with an SRS or disposing
of a front passenger airbag assembly, always first deploy the
airbag in accordance with the procedure described below. If any
abnormality occurs with the airbag deployment, contact the
SERVICE DEPT. of the 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 proce-
dure given in step 1–(g) in ”DISPOSAL”.
CAUTION:

Never dispose of 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 place away from electrical noise.

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 is very hot when the air-
bag is deployed, so leave it alone for at least 30 min-
utes after deployment.

Use gloves and safety glasses when handling the
front passenger airbag assembly with the deployed
airbag.

Always wash your hands with water after completing
the operation.

Do not apply water etc. to the front passenger airbag
assembly with the deployed airbag.
