DISPOSAL

HINT:

F

When scrapping vehicles equipped with an SRS or disposing of the front seat airbag assy 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 TOYOTA MOTOR SALES, U.S.A., INC.

F

When disposing of a front seat airbag assy with an airbag deployed in a collision, follow the same pro-

cedure given in step 1-(e) in ”DISPOSAL”.

CAUTION:

F

Never dispose of a front seat airbag assy which has

an undeployed airbag.

F

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.

F

When deploying the airbag, always use the specified

SST (SRS Airbag Deployment Tool), perform the

operation in a place away from electrical noise.

F

When deploying an airbag, perform the operation at

SST

least 10 m (33 ft) away from the airbag assy.

F

The front seat airbag assy is very hot when the airbag

is deployed, so leave it alone for at least 30 minutes

after deployment.
