Disposal

DISPOSAL

CAUTION / NOTICE / HINT

CAUTION:

Before performing pre-disposal deployment of any SRS part, review and closely follow all applicable environmental and hazardous material regulations. Pre-disposal deployment may be considered hazardous material treatment.

PROCEDURE

1. PRECAUTION

CAUTION:

• Use gloves and safety glasses when handling a front seat outer belt assembly with a deployed pretensioner.
• Always wash your hands with water after completing the operation.
• Do not apply water, etc. to a front seat outer belt assembly with a deployed pretensioner.
• When deploying a seat belt pretensioner, always use the specified SST (SRS airbag deployment tool). Perform the operation in a place away from electrical noise.
• Never dispose of a front seat outer belt assembly with a pretensioner that has not been deployed.
• The front seat outer belt assembly produces an exploding sound when the pretensioner is deployed, so perform the operation outdoors where it will not disturb nearby residents.
• When deploying a seat belt pretensioner, perform the operation at least 10 m (32.8 ft.) away from the vehicle.

HINT:

When scrapping a vehicle 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. If any abnormality occurs during deployment of the seat belt pretensioner, contact the SERVICE DEPARTMENT of the distributor.

2. DISPOSE OF FRONT SEAT OUTER BELT ASSEMBLY (When Installed to Vehicle) (When Installed to Vehicle)

NOTICE:

• When disposing of a front seat outer belt assembly with a pretensioner, never deploy the pretensioner in the customer's vehicle.
• Be sure to observe the following procedure when deploying a seat belt pretensioner.

HINT:

Prepare a 12 V battery as the power source to deploy the seat belt pretensioner.

(a) Check the function of SST.

SST: 09082-00700

CAUTION:

When deploying a seat belt pretensioner, always use the specified SST.

(1) Connect the red clip of SST to the positive (+) battery terminal and the black clip to the negative (-) battery terminal. HINT: At this time, do not connect the yellow connector. It will be connected to the seat belt pretensioner in a later step.

*a 12 V Battery

(2) Press the SST activation switch and check that the LED of the SST activation switch illuminates. CAUTION: If the LED is illuminated when the SST activation switch is not pressed, SST may be malfunctioning. In this case, do not use the malfunctioning SST.

SST: 09082-00700

SST: 09082-00802

09082-10801

09082-20801

NOTICE:

To avoid damaging the SST connector or wire harness, do not lock the secondary lock of the pretensioner connector.

(2) Move SST at least 10 m (32.8 ft.) away from the front of the vehicle.

CAUTION:

• Do not perform deployment with any of the doors or windows open.
• If deployment is performed with any of the doors or windows open, dust and gas may enter the eyes or be breathed in.

(3) Close all of the doors and windows of the vehicle.

NOTICE:

Do not damage the SST wire harness.

(f) Deploy the seat belt pretensioner.

(1) Check that no one is inside the vehicle or within a 10 m (32.8 ft.) radius of the vehicle.

(2) Connect the red clip of SST to the positive (+) battery terminal and the black clip to the negative (-) battery terminal.

(3) Press the SST activation switch to deploy the seat belt pretensioner.

HINT:

The seat belt pretensioner will deploy at the same time as the LED of SST illuminates.

CAUTION:

• The front seat outer belt assembly produces an exploding sound when the pretensioner is deployed, so perform the operation outdoors where it will not disturb nearby residents.
• If this procedure is performed indoors or on a rough road where safety cannot be ensured, unforeseen injuries may occur. Also, if this procedure is performed near a residential area, the deployment noise may disturb nearby residents.

(g) Dispose of the front seat outer belt assembly.

(1) Remove the front seat outer belt assembly and SST.

(2) Place the front seat outer belt assembly in a plastic bag, tie the end tightly, and dispose of it in the same way as other general parts.

• Do not apply water, etc. to a front seat outer belt assembly with a deployed pretensioner.
• If water is applied to the front seat outer belt assembly immediately after deployment, burns may be caused by the resulting steam.
• Always wear safety glasses and gloves when handling a front seat outer belt assembly with a deployed pretensioner.
• If a front seat outer belt assembly with a deployed pretensioner is touched without wearing safety glasses and gloves, hot parts may cause burns and dust may enter the eyes.
• After removal, quickly seal the front seat outer belt assembly in a plastic bag.
• Never dispose of a front seat outer belt assembly with a pretensioner that has not been deployed.
• If a front seat outer belt assembly with a pretensioner that has not been deployed is disposed of, and then deploys accidentally, unforeseen injuries may occur.
• Always wash your hands with water after completing the operation.

HINT:

When scrapping a vehicle, deploy the seat belt pretensioners, and then scrap the vehicle with the front seat outer belt assemblies installed.

3. DISPOSE OF FRONT SEAT OUTER BELT ASSEMBLY (When not Installed to Vehicle)

NOTICE:

• When disposing of a front seat outer belt assembly with a pretensioner, never deploy the pretensioner in the customer's vehicle.
