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

HINT:

When scrapping a Toyota Prius vehicle equipped with an SRS or disposing of the instrument panel passenger 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 the distributor.

2. DISPOSE OF INSTRUMENT PANEL PASSENGER AIRBAG ASSEMBLY (When Installed to Toyota Prius Vehicle)

HINT:

Prepare an auxiliary battery as the power source to deploy the airbag.

(a) Check the function of SST. Click here SST: 09082-00700

(b) Refer to Precaution.

Click here

(c) Disconnect the cable from the negative (-) auxiliary battery terminal.

CAUTION:

Wait at least 60 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.

(d) Remove the lower instrument panel sub-assembly.

Click here

(e) Disconnect the airbag connector from the instrument panel passenger airbag assembly.

NOTICE:

When disconnecting any airbag connector, take care not to damage the airbag wire harness.

HINT:

Refer to How to Connect or Disconnect Airbag Connector.

Click here

(f) Install SST.

CAUTION:

Check that there is no looseness in the instrument panel passenger airbag assembly or instrument panel safety pad sub-assembly.

(1) w/ Occupant Classification System: After connecting the following SST to each other, connect them to the instrument panel passenger airbag assembly. SST: 09082-00700 SST: 09082-00802 09082-10801 09082-30801 NOTICE: To avoid damaging the SST connector or wire harness, do not lock the secondary lock of the twin lock.

(2) w/o Occupant Classification System:

After connecting the following SST to each other, connect them to the instrument panel passenger airbag assembly.

SST: 09082-00700

SST: 09082-00802

09082-10801

09082-40800

NOTICE:

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

(3) Move SST at least 10 m (32.8 ft.) away from the front side window of the Toyota Prius vehicle.

*a Auxiliary Battery *b 10 m (32.8 ft.) or more

(4) Maintaining sufficient clearance for the SST wire harness in the front side window, close all doors and windows of the Toyota Prius vehicle.

NOTICE:

Take care not to damage the SST wire harness.

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

(g) Deploy the airbag.

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

(2) Press the SST activation switch to deploy the airbag.

HINT:

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

3. DISPOSE OF INSTRUMENT PANEL PASSENGER AIRBAG ASSEMBLY (When not Installed to Toyota Prius Vehicle)

NOTICE:

Be sure to perform the following procedure when deploying the airbag.

HINT:

Prepare an auxiliary battery as the power source to deploy the airbag.

(a) Check the function of SST. Click here SST: 09082-00700

(b) Remove the instrument panel passenger airbag assembly.

Click here

(c) Install SST.

(1) w/ Occupant Classification System: After connecting the following SST to each other, connect them to the instrument panel passenger airbag assembly. SST: 09082-00802 09082-10801 09082-30801

(d) Using braided wire, tie down the instrument panel passenger airbag assembly to an unneeded tire.

*a	Wire Diameter
*b	Stripped Wire Cross Sectional Area

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 instrument panel passenger airbag assembly, it may snap when the airbag is deployed. Always use a wire for Toyota Prius 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) Position the instrument panel passenger 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.)

*a

Inner Diameter

*b

Width

NOTICE:

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

(e) Place the tires.

(1) Place at least 2 tires under the tire to which the instrument panel passenger airbag assembly is tied. Minimum Tire Size: Width 185 mm (7.28 in.) Inner Diameter 360 mm (1.18 ft.) NOTICE: Do not place the SST connector under the tire because it could be damaged.

*a Tires (2 or more)

(2) Place at least 2 tires onto the tire to which the instrument panel passenger airbag assembly is tied. The top tire should have a wheel installed.

NOTICE:

The wheel and tires may be damaged by the airbag deployment, so use an unneeded wheel and tires.

(3) Tie the tires together with 2 wires. CAUTION: Make sure that the wires are tight. Looseness in the wires will result in the tires breaking loose when the airbag is deployed.

(f) Install SST.

(1) Connect the SST connector. SST: 09082-00700 NOTICE: To avoid damaging the SST connector or wire harness, do not lock the secondary lock of the twin lock. Also, secure some slack for the SST wire harness inside the tire.

(2) Move SST at least 10 m (32.8 ft.) away from the airbag tied down to the tire.

(g) Deploy the airbag.

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

(2) Check that no one is within a 10 m (32.8 ft.) radius of the tire to which the instrument panel passenger airbag assembly is tied.

(3) Press the SST activation switch to deploy the airbag.

CAUTION:

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