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 front seat cushion airbag assembly RH 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 front seat cushion airbag assembly RH.
The front seat cushion airbag assembly RH 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 front seat cushion airbag assembly RH with a deployed airbag.
Do not apply water etc. to a front seat cushion airbag assembly RH 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 front seat cushion airbag assembly RH, 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 TOYOTA MOTOR SALES, U.S.A., INC.

*1	Battery
*a	10 m or more

(4) 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.

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

(n) 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 and deploy the airbag.

CAUTION:

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

HINT:

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

Do not apply water etc. to a front seat cushion airbag assembly RH with a deployed airbag.
After removal, quickly seal the front seat cushion airbag assembly RH in a plastic bag.
Always wash your hands with water after completing the operation.

3. DISPOSE OF FRONT SEAT CUSHION AIRBAG ASSEMBLY RH (When not Installed in Vehicle)

NOTICE:

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

HINT:

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

(a) Check the function of SST.

Click here

SST: 09082-00700

(b) Remove the front seat cushion airbag assembly RH.

Click here

CAUTION:

Before removing the front seat assembly RH, wait at least 90 seconds after turning the power switch off and disconnecting the cable from the auxiliary battery negative (-) terminal.
When storing the front seat cushion airbag assembly RH, keep the airbag deployment side facing upward.

Wire:

Cross-sectional area of stripped wire

1.25 mm2 (0.0019 in.2) or more

CAUTION:

If the wire harness is too thin or an alternative object is used to tie down the front seat cushion airbag assembly RH, 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).

*a	Wire Diameter
*b	Stripped Wire Section

HINT:

To calculate the area of the cross-sectional area of stripped wire:

Area = 3.14 x (Diameter)2 / 4

(1) Install the 3 nuts to the front seat cushion airbag assembly RH.

(2) Wind the wires around the stud bolts of the front seat cushion airbag assembly RH as shown in the illustration.
