Steering Pad: Disposal: Disposal

WARNING:

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

  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 steering pad 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 (33 ft.) away from the steering pad.
    • The steering pad 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 steering pad with a deployed airbag.
    • Do not apply water etc. to a steering pad with a deployed airbag.
    • Always wash your hands with water after completing the operation.

    HINT: 

    When scrapping a vehicle equipped with an SRS or disposing of the steering pad, be sure to deploy the airbag first in accordance with the following procedure. If any abnormality occurs with the airbag deployment, contact the Service Dept. of TOYOTA MOTOR SALES, U.S.A., INC.

  2. DISPOSE OF STEERING PAD (WHEN INSTALLED IN VEHICLE) 
    NOTE:
    • When disposing of the steering pad, never use the customer's vehicle to deploy the airbag.
    • Be sure to observe the following procedure when deploying the airbag.

    HINT: 

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

    1. Check the function of SST.

      Wire

      Stripped wire section

      1.25 mm2 (0.0019 in.2 ) or more

      WARNING:

      If the wire harness is too thin or an alternative object is used to tie down the steering pad, it may snap when the airbag is deployed. Always use a wire for vehicle use with an area of at least 1.25 mm2 (0.0019 in.2 ).

      HINT: 

      To calculate the area of the stripped wire harness section:

      Area = 3.14 x (Diameter)2 / 4

      1. After connecting the 2 parts of the following SST to each other, connect them to the steering pad.

        WARNING:
        • Tightly wind the wires around the horn button contact plate without any slack.
        • Make sure that the wires are tight. If there is slack in the wires, the steering pad may break loose when the airbag is deployed.
      3. Face the airbag deployment side of the steering pad upward on top of an unneeded tire and wheel set. Separately tie the left and right sides of the steering pad to the wheel through the hub nut holes. Position the SST connector so that it hangs downward through the hub hole of the wheel.

        WARNING:
        • Make sure that the wires are tight. If there is slack in the wires, the steering pad may break loose when the airbag is deployed.
        • Always tie down the steering pad with the airbag deployment side facing upward.
        NOTE:

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

    4. Install SST.
      WARNING:

      Place the wheel on level ground.

      1. Connect the SST connector.

      Fig 15: Identifying Cardboard Box Dimensions
      GTY103282Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      1. Cover the steering pad with a cardboard box.
      2. Place weights on the cardboard box in 4 places totalling at least 190 N (19 kg, 43 lb).

        Minimum cardboard box size

        Must exceed the following dimensions

        X 

        460 mm (1.51 ft.)

        Y 

        650 mm (2.13 ft.)

        NOTE:
        • When dimension Y of the cardboard box exceeds the diameter of the disc wheel with the tire which the steering pad is tied to, 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 steering pad (using tires).
      1. Place at least 3 tires without wheels onto the wheel and tire to which the steering pad is tied.

      2. Place a wheel and tire on top.

        Minimum tire size

        Must exceed the following dimensions

        Width

        185 mm (7.28 in.)

        Inner diameter

        360 mm (1.18 ft.)

        WARNING:

        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. Tie the tires together with 2 wires.

        WARNING:

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

      2. Check that no one is within a 10 m (33 ft.) radius of the wheel to which the steering pad is tied.
      3. Press the SST activation switch and deploy the airbag.
        WARNING:

        Before deployment, make sure that no one is near the airbag.

        HINT: 

        The airbag is deployed as the LED of the SST activation switch comes on.

    8. Dispose of the steering pad.
      WARNING:
      • The steering pad 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 steering pad with a deployed airbag.
      • Do not apply water etc. to a steering pad with a deployed airbag.
      • Always wash your hands with water after completing the operation.
      1. Remove the steering pad from the wheel.
      2. Place the steering pad in a plastic bag, tie it tightly and dispose of it according to local regulations.
