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
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 lower No. 1 instrument panel 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 lower No. 1 instrument panel airbag assembly.
The lower No. 1 instrument panel 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 lower No. 1 instrument panel airbag assembly with a deployed airbag.
Do not apply water, etc. to a lower No. 1 instrument panel airbag assembly with a deployed airbag.
Always wash your hands with water after completing the operation.
Tech Tips
When scrapping a vehicle equipped with an SRS or disposing of the lower No. 1 instrument panel 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.
DISPOSE OF LOWER NO. 1 INSTRUMENT PANEL AIRBAG ASSEMBLY (When Installed to Vehicle)
Note
When disposing of a lower No. 1 instrument panel airbag assembly, never use the customer's vehicle to deploy the airbag.
Be sure to perform the following procedure when deploying the airbag.
Tech Tips
Prepare a battery as the power source to deploy the airbag.
Check the function of SST.
Refer to Precaution.
Disconnect the cable from the negative (-) battery terminal.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
Remove the No. 1 instrument panel under cover sub-assembly.
Disconnect the lower No. 1 instrument panel airbag assembly connector.
Using a screwdriver with its tip wrapped with protective tape, disconnect the airbag connector.
Note
When disconnecting any airbag connector, take care not to damage the airbag wire harness.
Install SST.
CAUTION:
Check that there is no looseness in the lower No. 1 instrument panel airbag assembly.
After connecting the following SST to each other, connect them to the lower No. 1 instrument panel airbag assembly.
Note
To avoid damaging the SST connector or wire harness, do not lock the secondary lock of the twin lock.
*a | Battery |
*b | 10 m (32.8 ft.) or more |
Move SST at least 10 m (32.8 ft.) away from the front side window of the vehicle.
Maintaining sufficient clearance for the SST wire harness in the front side window, close all doors and windows of the vehicle.
Note
Take care not to damage the SST wire harness.
Connect the red clip of SST to the positive (+) battery terminal and the black clip of SST to the negative (-) battery terminal.
Deploy the airbag.
Check that no one is inside the vehicle or within a 10 m (32.8 ft.) radius of the vehicle.
Press the SST activation switch to deploy the airbag.
CAUTION:
Before deployment, make sure that no one is inside or near the vehicle.
The lower No. 1 instrument panel 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 lower No. 1 instrument panel airbag assembly with a deployed airbag.
Do not apply water, etc. to a lower No. 1 instrument panel airbag assembly with a deployed airbag.
Always wash your hands with water after completing the operation.
Tech Tips
The airbag is deployed as the LED of the SST activation switch comes on.
DISPOSE OF LOWER NO. 1 INSTRUMENT PANEL AIRBAG ASSEMBLY (When not Installed to Vehicle)
Note
Be sure to perform the following procedure when deploying the airbag.
Tech Tips
Prepare a battery as the power source to deploy the airbag.
Check the function of SST.
Remove the lower No. 1 instrument panel airbag assembly.
CAUTION:
Before removing the lower No. 1 instrument panel airbag assembly, wait at least 90 seconds after turning the engine switch off and disconnecting the cable from the negative (-) battery terminal.
Deployment Side |
When storing the lower No. 1 instrument panel airbag assembly, keep the airbag deployment side facing upward.
*a | Wire Diameter |
*b | Stripped Wire Cross Sectional Area |
Using braided wire, tie down the lower No. 1 instrument panel 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 lower No. 1 instrument panel 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).
Tech Tips
To calculate the cross sectional area of the stripped wire:
Cross sectional area = 3.14 x (Diameter)2/ 4
Position the lower No. 1 instrument panel 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 | Width | *b | Inner Diameter |
CAUTION:
Make sure that the wires are tight. If there is slack in the wires, the lower No. 1 instrument panel airbag assembly may break loose when the airbag is deployed.
Deployment Side |
Always tie down the lower No. 1 instrument panel airbag assembly with the airbag deployment side facing inside the tire as shown in the illustration.
Note
The tire may be damaged by the airbag deployment, so use an unneeded tire.
Install SST.
After connecting the following SST to each other, connect them to the lower No. 1 instrument panel airbag assembly.
Place the tires.
*a | Tires (2 or more) |
*b | Inner Diameter |
*c | Width |
Place at least 2 tires under the tire to which the lower No. 1 instrument panel airbag assembly is tied.
Minimum Tire Size |
---|
Width |
185 mm (7.28 in.) |
Inner Diameter |

Note
Do not place the SST connector under the tire because it could be damaged.
Place at least 2 tires onto the tire to which the lower No. 1 instrument panel airbag assembly is tied. The top tire should have a wheel installed.
Note
The wheel and tires may be damaged by the airbag deployment, so use an unneeded wheel and tires.
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.
Install SST.

Connect the SST connector.
Note
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.
Move SST at least 10 m (32.8 ft.) away from the airbag tied down to the tire.
Deploy the airbag.
Connect the red clip of SST to the positive (+) battery terminal and the black clip of SST to the negative (-) battery terminal.
Check that no one is within a 10 m (32.8 ft.) radius of the tire to which the lower No. 1 instrument panel airbag assembly is tied.
