STEERING PAD 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:


    • 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 horn button assembly with an undeployed airbag.

    • The airbag produces an exploding sound when it is deployed, so perform the operation outdoors 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 operation in a place away from electrical noise.

    • When deploying the airbag, perform the operation at least 10 m (32.8 ft.) away from the horn button assembly.

    • The horn button assembly becomes extremely hot when the airbag is deployed, so do not touch it for at least 30 minutes after deployment.

    • Use gloves and safety glasses when handling a horn button assembly with a deployed airbag.

    • Do not apply water etc. to a horn button assembly with a deployed airbag.

    • Always wash your hands with water after completing the operation.

    Tech Tips

    When scrapping a vehicle equipped with an SRS or disposing of the horn button assembly, be sure to deploy the airbag first in accordance with the procedure described below. If any abnormality occurs with the airbag deployment, contact the Service Dept. of the distributor.

  2. DISPOSE OF HORN BUTTON ASSEMBLY (When Installed in Vehicle)

    Note


    • When disposing of the horn button assembly, never use the customer's vehicle to deploy the airbag.

    • Be sure to observe the following procedure when deploying the airbag.

    Tech Tips

    Prepare a 12 V battery as the power source to deploy the airbag.

        Face the airbag deployment side of the horn button assembly upward on top of an unneeded tire and wheel set. Separately tie the left and right sides of the horn button assembly to the wheel through the hub nut holes. Position the SST connector so that it hangs downward through the hub hole of the wheel.

        Minimum tire size
        Width
        185 mm (7.28 in.)
        Inner diameter
        360 mm (1.18 ft.)

        CAUTION:


        • Make sure that the wires are tight. If there is slack in the wires, the horn button assembly may break loose when the airbag is deployed.

        • Always tie down the horn button assembly with the airbag deployment side facing upward.

        Note

        The wheel will be damaged by the airbag deployment, so use an unneeded wheel.

    4. B005ZQEE01

        Note


        • When dimension Y of the cardboard box exceeds the diameter of the wheel and tire to which the horn button assembly is tied, X should be the following size.

          X = 460 mm (1.51 ft.) + width of tire

        • If a cardboard box smaller than the specified size is used, it may be broken by the shock from the airbag deployment.

    6. Cover the horn button assembly (using tires).


      1. B005YT7E11
        Text in Illustration
        *1 Tires (3 or more)
        *a Inner Diameter
        *b Width

        Place at least 3 tires without wheels onto the wheel and tire to which the horn button assembly is tied.

        Minimum tire size
        Width
        185 mm (7.28 in.)
        Inner diameter
        360 mm (1.18 ft.)
      2. Place a wheel and tire on top.

        CAUTION:

        Do not use tires with wheels except for on the top and bottom.

        Note


        • The tires may be damaged by the airbag deployment, so use unneeded tires.

        • Do not place the SST connector under the tire because it could be damaged.

      3. B005ZU5

        Tie the tires together with the 2 wires.

        CAUTION:

        Make sure that the wires are tight. Looseness in the wires results in the tires breaking loose when the airbag is deployed.

    7. Deploy the airbag.

      CAUTION:


      • The horn button assembly becomes extremely hot when the airbag is deployed, so do not touch it for at least 30 minutes after deployment.

      • Use gloves and safety glasses when handling a horn button assembly with a deployed airbag.

      • Do not apply water etc. to a horn button assembly with a deployed airbag.

      • Always wash your hands with water after completing the operation.


      1. Remove the horn button assembly from the wheel.

      2. Place the horn button assembly in a plastic bag, tie it tightly and dispose of it according to local regulations.
