DISPOSAL

HINT:
When scrapping vehicles equipped with an SRS or disposing
of the side airbag assembly always first deploy the airbag in ac-
cordance with the procedure described below. If any abnormal-
ity occurs with the airbag deployment, contact the SERVICE

CAUTION:

Never dispose of a side 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.

after deployment.

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

Always wash your hands with water after completing
the operation.

Do not apply water, etc. to a side airbag assembly with
