HINT:
When scrapping a vehicle, deploy the airbag and scrap the ve-
hicle with the front seat airbag assy LH being installed.
2. DISPOSE OF FRONT SEAT AIRBAG ASSY LH (WHEN
DISPOSING OF AIRBAG ASSEMBLY DEPLOYMENT
METHOD)
NOTICE:
When disposing of the front seat airbag assy LH only,
never use the customer's vehicle to deploy the air-
bag.
Be sure to follow the procedure detailed below when
deploying the airbag.
HINT:
Prepare a battery as the power source to deploy the airbag.
(a)Check the function of the SST(s) (See step 1± (a) on page 60±19).
(b) Remove the front seat airbag assy LH. (1)Remove the front seat assy LH (See page 72±16).
(2) Remove the 2 nuts and the front seat airbag assy LH from the seatback assembly.
CAUTION:
When removing the front seat airbag assy LH, work
must be started 90 seconds after the ignition switch
is turned to the ºLOCKº position and the negative (±)
terminal cable is disconnected from the battery.
When storing the front seat airbag assy LH, keep the
upper surface of the airbag deployment side facing
upward.
(c) Using a service±purpose wire harness for the vehicle, tie down the front seat airbag assy LH to the tire.
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 an alternative object
is used to tie down the front seat airbag assy LH, 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 has a diameter at least 1.25 mm
2 (0.0019 in2).

(1) Install the 2 nuts in the front seat airbag assy LH.
(2) Wind the wire harness around the stud bolts of the front seat airbag assy LH as shown in the illustra-
tion.
(3) Position the front seat airbag assy LH inside the tire with the airbag deployment direction facing inside.
Tire size: Must exceed the following dimensions
Width: 185 mm (7.28 in.)
Inner diameter: 360 mm (14.17 in.)
CAUTION:
Make sure the wire harness is tight. It is highly dan-
gerous when looseness in the wire harness results in
the front seat airbag assy LH coming free due to the
shock from the airbag deployment.
Always tie down the front seat airbag assy LH with the
airbag deployment direction facing inside the tire.
NOTICE:
The tire will be marked by the airbag deployment, so use a
redundant tire.
(d) Install the SST(s). Connect the connector of SST(s) to the front seat airbag
assy LH connect.

(e) Place the tires.
(1) Place at least 2 tires under the tire to which the frontseat airbag assy LH is tied.
(2) Place at least 2 tires over the tire to which the front seat airbag assy LH is tied. The top tire should have
the disc wheel installed.
NOTICE:
Do not place the SST(s) connector under the tire because
the SST(s) connector could be damaged.
(3) Tie the tires together with 2 wire harnesses.
CAUTION:
Make sure that the wire harness is tight. It is highly danger-
ous when looseness in the wire harness results in the tires
coming free due to the shock from the airbag deployment.
HINT:
Place the SST(s) connector and the wire harness inside tires.
Secure at least 1 m (3 ft) of slack for the wire harness.
(f) Install the SST(s).
Connect the connector of the SST(s).
SST 09082±00700
NOTICE:
To avoid damaging the SST(s) connector and wire harness,
do not lock the secondary lock of the twin lock. Also, se-
cure some slack for the SST(s) wire harness inside the tire.
(g) Deploy the airbag. (1) Connect the red clip of the SST(s) to the battery
positive (+) terminal and the black clip of the SST(s)
to the battery negative (±) terminal.
(2) Check that no one is within a 10 m (33 ft) radius of the tire to which the front seat airbag assy LH is tied.
(3) Press the activation switch of the SST(s) and
deploy the airbag.
HINT:
The airbag is deployed as the LED of the SST(s) activation
switch comes on.

30 minutes after deployment.
Use gloves and safety glasses when handling the
front seat airbag assy LH with the deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water etc. to the front seat airbag assy
LH with the deployed airbag.
(1) Remove the front seat airbag assy LH from the tire.
(2) Place the front seat airbag assy LH in a plastic bag, tie the end tightly and dispose of it in the same way
as other general parts disposal.

DISPOSAL
HINT:
When scrapping a vehicle equipped with the SRS or disposing of a horn button\
assy, be sure to deploy the
airbag first in accordance with the procedure described below. If any abnormality occurs with the airbag de-
ployment, contact the SERVICE DEPT. of TOYOTA MOTOR SALES, U.S.A., INC.
CAUTION:
Never dispose of the horn button assy that has an un-
deployed airbag.
The airbag produces an extremely exploding sound
when it is deployed, so perform the operation out-
doors and where it will not create a nuisance to
nearby residents.
When deploying the airbag, always use the specified
SST(s) (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 (33 ft) away from the horn button assy.
The horn button assy is extremely hot when the air-
bag is deployed, so do not touch it for at least 30 min-
utes after deployment.
Use gloves and safety glasses when handling the
horn button assy with the deployed airbag.
Do not apply water, etc. to the horn button assy with
the deployed airbag.
Always wash your hands with water after completing
the operation.
