(2) Using a service-purpose wire harness tie down the
steering wheel pad to the disc wheel.
Wire harness: Stripped wire harness section
1.25 mm
2
or more (0.0019 in2. or more).
HINT:
To calculate the square of the stripped wire harness section:
Square - 3.14 x (Diameter)
2
divided by 4
CAUTION:
If a wire harness which is too thin or some other thing is
used to tie down the steering wheel pad, it may be snapped
by the shock when the airbag is deployed. This is highly
dangerous. Always use a wire harness for vehicle use
which is at least 1.25 mm
2
(0.0019 in2).
(3) Using 3 wire harness, wrap the wire harness at least
2 times each around the bolts installed on the left
and right sides of the steering wheel pad.
CAUTION:
Tightly wind the wire harness around the bolts so that
there is no slack.
If there is slackness in the wire harness, the steering
wheel pad may come loose due to the shock when the
airbag is deployed. This is highly dangerous.
(4) Face the upper surface of the steering wheel pad
upward. Separately tie the left and right sides of the
steering wheel pad to the disc wheel through the
hub nut holes. Position the steering wheel pad con-
nector so that it hangs downward though a hub hole
in the disc wheel.
CAUTION:
Make sure that the wire harness is tight. It is very dan-
gerous when looseness in the wire harness results in
the steering wheel pad coming free through the shock
from the airbag deploying.
Always tie down the steering wheel pad with the pad
side facing upward. It is very dangerous if the steer-
ing wheel pad is tied down with the metal surface fac-
ing upward as the wire harness will be cut by the
shock of the airbag deploying and the steering wheel
pad will be thrown into the air.
NOTICE:
The disc wheel will be marked by airbag deployment, so
use the spare disc wheel.

(d) Install the SST.
CAUTION:
Place the disc wheel on the level ground.
Connect the SST connector to the steering wheel pad
connector.
SST 09082-00700
NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock. Also, se-
cure some slack for the SST wire harness inside the disc
wheel.
(e) Cover the 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 196 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 to which the steer-
ing wheel pad is tied -
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 (7.28 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 spare tires.
(f) 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.
(g) Dispose of the steering wheel pad (with airbag).
CAUTION:
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 deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a steering wheel pad with
deployed airbag.
(1) Remove the steering wheel pad from the disc
wheel.
(2) Place the steering wheel pad in a vinyl bag, tie the
end tightly and dispose of it in the same way as oth-
er general parts disposal.

DISPOSAL
HINT:
When a scrapping vehicle equipped with an SRS or disposing
of a front passenger airbag assembly, always first deploy the
airbag 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.
When disposing of a front passenger airbag assembly with an
airbag deployed in a collision, follow the same procedure given
in step 1-(e) in ºDISPOSALº.
CAUTION:
Never dispose of a front passenger airbag assembly
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
When deploying an airbag, perform the operation
from at least 10 m (33 ft) away from the front passen-
ger airbag assembly.
The front passenger airbag assembly is very hot
when the airbag is deployed, so leave it alone for at
least 30 minutes after deployment.
Use gloves and safety glasses when handling a front
passenger airbag assembly with deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a front passenger airbag
assembly with deployed airbag.
