DISPOSAL
HINT:

Use the same procedures for the RH side and LH side.

The procedures listed below are for the LH side.

When scrapping a vehicle equipped with the SRS or dis-
posing of the front seat airbag assembly LH, 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 DEPT. of TOYOTA
MOTOR SALES, U.S.A., INC.
CAUTION:

Never dispose of a front seat airbag assembly that
has an undeployed 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 resi-
dents.

When deploying the airbag, always use the specified
SST (SRS Airbag Deployment Tool). Perform the op-
eration in a place away from electrical noise.

When deploying the airbag, perform the operation at
least 10 m (33 ft) away from the front seat airbag as-
sembly.

The front seat airbag assembly 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 front
seat airbag assembly with a deployed airbag.

Always wash your hands with water after completing
the operation.

Do not apply water, etc. to a front seat airbag assem-
bly with a deployed airbag.
HINT:
Prepare a battery as the power source to deploy the airbag.

RS±23).
SST 09082±00700
(b) Precaution (see page RS±1 and RS±3).
(c) Disconnect the cable from the negative battery terminal.
Wait for 90 seconds after disconnecting the cable to prevent the
airbag working.

front seat airbag assembly LH.
NOTICE:
When handling the airbag connector, take care not to dam-
age the airbag wire harness.
(f) Install the SST.
(1) Connect the connectors of the SST to the airbag
connector.
SST 09082±00700, 09082±00750
NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock.
(2) Move the SST at least 10 m (33 ft) away from the ve-
hicle side window.
(3) Maintaining enough clearance for the SST wire har-
ness in the front side window, close all doors and
windows of the vehicle.
NOTICE:
Take care not to damage the SST wire harness.
(4) Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip to the battery neg-
ative (±) terminal.

(g) Deploy the airbag.
(1) Check that no one is inside the vehicle or within a
10 m (33 ft) radius of the vehicle.
(2) Press the SST activation switch and deploy the air-
bag.
CAUTION:

When deploying the airbag, make sure that no one is
near the vehicle.

The front seat airbag assembly 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 front
seat airbag assembly with a deployed airbag.

Do not apply water, etc. to a front seat airbag assem-
bly with a deployed airbag.

Always wash your hands with water after completing
the operation.
HINT:
The airbag deploys as the LED of the SST activation switch
comes on.
2. DEPLOYMENT WHEN DISPOSING OF SIDE AIRBAG
ASSEMBLY
NOTICE:

When disposing of the side airbag assembly, never
use the customer's vehicle to deploy the airbag.

Be sure to follow the procedure given below when de-
ploying the airbag.
HINT:
Prepare a battery as the power source to deploy the airbag.
(a) Check the function of the SST (see step 1±(a)).
(b) Remove the front seat airbag assembly
(see page BO±111 (power adjuster type) and BO±125
(manual adjuster type)).
(c) Remove the seatback assembly (see page RS±46).

(d) Remove the 2 nuts and side airbag assembly from the
seatback assembly.
CAUTION:

When removing the front seat airbag assembly, 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 passenger airbag assembly,
keep the airbag deployment side facing upward.
(e) Using a service±purpose wire harness for the vehicle, tie
down the front passenger airbag assembly to the tire.

HINT:
To calculate the area of the stripped wire harness section:
Area = 3.14 x (Diameter)
2 divided by 4
CAUTION:
If the wire harness is too thin or an alternative object is
used to tie down the front passenger airbag assembly, it
may be snapped by the shock when the airbag is deployed.
Always use a wire harness for vehicle use with an area of
at least 1.25 mm
2
(0.0019 in.2).
(1) Install the 2 nuts to the side airbag assembly.

(2) Wind the wire harness around the stud bolts of the
side airbag assembly as shown in the illustration.

with the airbag deployment direction facing inside.
Tire size: Must exceed the following dimensions:
Width: 185 mm (7.28 in.)

CAUTION:

Make sure that the wire harness is tight. If there is
slack in wire harness, the side airbag assembly may
become loose due to the shock when the airbag is
deployed.

Always tie down the side airbag assembly with the
airbag deployment side facing inside the tire.
NOTICE:
The tire will be marked by the airbag deployment, so use an
extra tire.
(f) Install the SST.
(1) Connect the SST connector to the side airbag as-
sembly connector.
SST 09082±00750
(g) Place the tires.
(1) Place at least 2 tires under the tire which the front
seat airbag assembly is tied to.
(2) Place at least 2 tires over the tire which the front
seat airbag assembly is tied to. The top tire should
have the disc wheel installed.
NOTICE:
Do not place the SST connector under the tire because it
could be damaged.

(3) Tie the tires together with 2 wire harness.
CAUTION:
Make sure that the wire harness is tight. Looseness in the
wire harness results in the tires coming free due to the
shock when the airbag is deployed.
(h) Install the SST.
Connect the connectors of the 2 SST to the side airbag
assembly connector.

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 tire.
(i) Deploy the airbag.
(1) Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip of the SST to the
battery negative (±) terminal.
(2) Check that no one is within a 10 m (33 ft) radius of
the tire which the front seat airbag assembly LH is
tied to.
(3) Press the SST activation switch and deploy the air-
bag.
CAUTION:
When deploying the airbag, make sure that no one is near
the tire.
