DISPOSAL
HINT:
When scrapping vehicle equipped with an SRS or disposing of
a steering wheel pad (with airbag), always first deploy the air-
bag in accordance with the procedure described below. If any
abnormality occurs with the airbag deployment, contact the
SERVICE DEPT. of the DISTRIBUTOR. When disposing of a
steering wheel pad with an airbag deployed in a collision, follow
the same procedure given in step 1±(g) in ºDISPOSALº.
CAUTION:

Never dispose of a steering wheel pad which has an
undeployed airbag.

The airbag produces a sizeable exploding sound
when it deploys, so perform the operation out±of±
doors 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 op-
eration in a place away from electrical noise.
SST 09082±00700, 09082±00760

When deploying an airbag, perform the operation at
least 10 m (33 ft) away from the steering wheel pad.

The steering wheel pad is very hot when the airbag is
deployed, so leave it alone for at least 30 minutes af-
ter deployment.

Use gloves and safety glasses when handling a steer-
ing wheel pad with the deployed airbag.

Always wash your hands with water after completing
the operation.

Do not apply water, etc. to a steering wheel pad with
the deployed airbag.

(f) Cover steering wheel pad with cardboard box or tires.

Covering method using cardboard box:
Cover the steering wheel pad with the cardboard
box and weight the cardboard box down in 4 places
with at least 190 N (20 kg, 44 lb).
Size of cardboard box:
Must exceed the following dimensions:
x=460 mm (18.11 in.)
When dimension of the cardboard box exceeds the di-
ameter of the disc wheel with tire which the steering
wheel pad is tied to±
x=460 mm (18.11 in.) + width of tire
y= 650 mm (25.59 in.)
NOTICE:
If a cardboard box smaller than the specified size is used,
the cardboard box will be broken by the shock from the air-
bag deployment.

Covering method using tires:
Place at least 3 tires without disc wheel on top of the
disc wheel with tire to which the steering wheel pad
is tied.
Tire size: Must exceed the following dimensions±
Width: 185 mm (7.87 in.)
Inner diameter: 360 mm (14.17 in.)
CAUTION:
Do not use tires with disc wheels.
NOTICE:
The tires may be marked by the airbag deployment, so use
the redundant tires.
(g) Deploy the airbag.
(1) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the battery negative
(±) terminal.
(2) Check that no one is within 10 m (33 ft) area around
the disc wheel which the steering wheel pad is tied
to.
(3) Press the SST activation switch and deploy the air-
bag.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.
