CAUTION / NOTICE / HINT
Tech Tips
When scrapping a vehicle equipped with an SRS or disposing of the steering pad, 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 department of the distributor.
CAUTION:
Never dispose of a steering pad that has an unactivated 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 steering pad.
The steering pad 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 steering pad with a deployed airbag.
Do not apply water, etc. to a steering pad with a deployed airbag.
Always wash your hands with water after completing the operation.
An airbag or pretensioner may be activated by static electricity. To prevent this, be sure to touch a metal surface with bare hands to discharge static electricity before performing this procedure.

Remove the steering pad Click here.
CAUTION:
Before removing the steering pad, wait at least 90 seconds after turning the power switch off and disconnecting the cable from the negative (-) battery terminal.
When storing the steering pad, keep the airbag deployment side facing upward.
Using braided wire, tie down the steering pad to an unneeded wheel.
| *a | Wire Diameter |
| *b | Stripped Wire |
| 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 steering pad, 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).
Tech Tips
To calculate the area of the stripped wire:
Area = 3.14 x (Diameter)2/ 4
After connecting the following SST to each other, connect them to the steering pad.
| *a | 2 times or more |
Wind 3 wires at least 2 times each around each of the pins.
CAUTION:
Tightly wind the wires around the snap pins without any slack.
Make sure that the wires are tight. If there is slack in the wires, the steering pad may break loose when the airbag is deployed.
Face the airbag deployment side of the steering pad upward on top of an unneeded tire and wheel set. Separately tie the left and right sides of the steering pad to the wheel through the hub nut holes. Position the SST connector so that it hangs downward through the hub hole of the wheel.
CAUTION:
Make sure that the wires are tight. If there is slack in the wires, the steering pad may break loose when the airbag is deployed.
Always tie down the steering pad with the airbag deployment side facing upward.
Note
The tire and wheel may be damaged by the airbag deployment, so use unneeded tire and wheel.
Install SST.
CAUTION:
Place the wheel on level ground.
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 disc wheel.
