Disposal [10/2017 - 10/2020]: Procedure

  1. PRECAUTION 
    WARNING:
    • An airbag or pretensioner may be activated by static electricity. To prevent this, be sure to touch a metal surface with your bare hands to discharge static electricity before performing this procedure.
    • Never dispose of a rear seat outer belt assembly with a pretensioner that has not been deployed.
    • The rear seat outer belt assembly produces an exploding sound when the pretensioner deploys, so perform the operation outdoors where it will not disturb local residents.
    • When deploying a seat belt pretensioner, always use the specified SST (SRS airbag deployment tool). Perform the operation in a place away from electrical interference.
    • When deploying a seat belt pretensioner, perform the operation at least 10 m (32.8 ft.) away from the vehicle.
    • The rear seat outer belt assembly becomes extremely hot when the pretensioner is deployed, so do not touch it for at least 30 minutes after deployment.
    • Use gloves and safety glasses when handling a rear seat outer belt assembly with a deployed pretensioner.
    • Do not apply water, etc. to a rear seat outer belt assembly with a deployed pretensioner.
    • Always wash your hands with water after completing the operation.

    HINT: 

    When scrapping vehicles equipped with a seat belt pretensioner or disposing of a front seat outer belt assembly (with a seat belt pretensioner), always deploy the seat belt pretensioner first in accordance with the procedure described below.
