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:
HINT:
When scrapping a vehicle equipped with an SRS or disposing of the front 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.
2. DISPOSE OF FRONT SEAT AIRBAG ASSEMBLY (When Installed to Vehicle)
NOTICE:
HINT:
Prepare a 12 V battery as the power source to deploy the airbag.
(a) Check the function of SST. Click here

(c) Disconnect the cable from the negative (-) auxiliary battery terminal.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.
(d) Disconnect the front seat airbag assembly connector under the front seat assembly.
NOTICE:
When disconnecting any airbag connector, take care not to damage the airbag wire harness.

Slide in this Direction |
(2) Push down the white housing lock again and disconnect the connector.
NOTICE:
Do not push down the part (A) shown in the illustration when disconnecting the connector.
(e) Install SST.
CAUTION:
Check that there is no looseness in the front seat assembly.
(1) After connecting the following SST to each other, connect them to the front seat airbag assembly. SST: 09082-00700 SST: 09082-00820 NOTICE: To avoid damaging the SST connector or wire harness, do not lock the secondary lock of the twin lock. |
|
(2) Move SST at least 10 m (32.8 ft.) away from the front side window of the vehicle. |
|
(3) Maintaining sufficient clearance for the SST wire harness in the front side window, close all doors and windows of the vehicle.
NOTICE:
Take care not to damage the SST wire harness.
(4) Connect the red clip of SST to the positive (+) battery terminal and the black clip of SST to the negative (-) battery terminal.
(f) Deploy the airbag.
(1) Check that no one is inside the vehicle or within a 10 m (32.8 ft.) radius of the vehicle.
(2) Press the SST activation switch to deploy the airbag.
CAUTION:
HINT:
The airbag is deployed as the LED of the SST activation switch comes on.
3. DISPOSE OF FRONT SEAT AIRBAG ASSEMBLY (When not Installed to Vehicle)
NOTICE:
Be sure to perform the following procedure when deploying the airbag.
HINT:
Prepare a 12 V battery as the power source to deploy the airbag.
(a) Check the function of SST. Click here

(c) Using braided wire, tie down the front seat 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 front 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 front seat airbag assembly. |
|
(2) Wind 2 or more wires around the stud bolts of the front seat airbag assembly as shown in the illustration. |
|
(3) Position the front seat airbag assembly inside the tire with the airbag deployment side facing inward.

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 front seat airbag assembly connector. SST: 09082-00820 |
|
(e) Place the tires.
(1) Place at least 2 tires under the tire to which the front seat 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. |
|
(2) Place at least 2 tires onto the tire to which the front seat 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 (+) battery terminal and the black clip of SST to the negative (-) battery terminal.
(2) Check that no one is within a 10 m (32.8 ft.) radius of the tire to which the front seat 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.
HINT:
The airbag is deployed as the LED of the SST activation switch comes on.
(h) Dispose of the front seat airbag assembly.
CAUTION:
(1) Remove the front seat airbag assembly from the tire.
(2) Place the front seat airbag assembly in a plastic bag, tie it tightly, and dispose of it according to local regulations.
