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 ”DISPOSAL”.
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.

tive (+) terminal and the black clip to the battery neg-
ative (–) terminal.

HINT:
Do not connect the yellow connector which will be connected
with the supplemental restraint system.

(2)

Check functioning of SST.
Press the SST activation switch, and check that the
LED of the SST activation switch lights up.

CAUTION:
If the LED lights up when the activation switch is not being
pressed, SST malfunction is probable, so definitely do not
use the SST.

(b)
