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:

• An airbag or pretensioner may be accidentally deployed 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 airbag assembly with an undeployed airbag.
• The airbag produces an exploding sound when it is deployed, so perform the operation outdoors where it will not disturb 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 rear seat airbag assembly.
• The rear seat airbag 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 rear seat airbag assembly with a deployed airbag.
• Do not apply water, etc. to a rear seat airbag assembly 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 rear seat airbag assembly, be sure to deploy the airbag first in accordance with the following procedure. If any abnormality occurs with the airbag deployment, contact the Service Department of TOYOTA MOTOR SALES, U.S.A., INC.

  Deployment Side

(c) Using braided wire, tie down the rear seat airbag assembly to an unneeded tire.

Wire:

Stripped Wire Cross Sectional Area

1.25 mm2 (0.0019 in.2) or more

CAUTION:

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

HINT:

To calculate the cross sectional area of the stripped wire:

Cross sectional area = 3.14 x (Diameter)2 / 4

(1) Install the 2 nuts to the rear seat airbag assembly.

(2) Wind 2 or more wires around the stud bolts of the rear seat airbag assembly as shown in the illustration.

(3) Position the rear seat airbag assembly inside the tire with the airbag deployment side facing inward.

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 rear seat airbag assembly may break loose when the airbag is deployed.
• Always tie down the rear seat airbag assembly with the airbag deployment side facing inside the tire.

  Deployment Side

NOTICE:

The tire may be damaged by the airbag deployment, so use an unneeded tire.

(d) Install SST.

(1) Connect the SST connector to the rear seat airbag assembly connector. SST: 09082-00820

(e) Place the tires.
