DISPOSAL
HINT:
When scrapping vehicle equipped with an SRS or disposing of
a front passenger airbag assembly, 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 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 ”DISPOSAL”.
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 at
least 10 m (33 ft) away from the front passenger air-
bag 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.

1. AIRBAG DEPLOYMENT WHEN SCRAPPING VE-
HICLE
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Check functioning of the SST. (See page RS−11 )
(b) Disconnect the airbag connector. (1) Remove the glove compartment door.
(2) Remove the No.1 under cover.
NOTICE:
When handling the airbag connector , take care not to dam-
age the airbag wire harness.
(3) Pull up the connector.
(4) Disconnect the airbag connector.
(c) Install the SST. (1) Connect the SST connector to the front passengerairbag assembly connector.
SST 09082−00700
NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock.
(2) Move the SST to at least 10 m (33 ft) away from the
front of the vehicle.
(3) Close all the doors and windows of the vehicle.
NOTICE:
Take care not to damage the SST wire harness.
(4) Connect the SST red clip to the battery positive (+)terminal and the black clip to the negative (+) termi-
nal.
(d) Deploy the airbag. (1) Confirm that no one is inside the vehicle or within 10
m (33 ft) area around the vehicle.
(2) 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.

(e) Dispose of the front passenger airbag assembly.
CAUTION:
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.
(1) When scrapping a vehicle, deploy the airbag and scrap the vehicle with the front passenger airbag
assembly still installed.
(2) When moving a vehicle for scrapping which has a front passenger airbag assembly with deployed air-
bag, use gloves and safety glasses.
2. DEPLOYMENT WHEN DISPOSING OF FRONT PAS- SENGER AIRBAG ASSEMBLY ONLY
NOTICE:
When disposing of the front passenger airbag assem-
bly only, never use the customer’s vehicle to deploy
the airbag.
Be sure to follow the procedure given below when de-
ploying the airbag.
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Remove the front passenger airbag assembly. (See page RS−22 )
CAUTION:
When removing the front passenger airbag assembly,
work must be started 90 seconds after the ignition
switch is turned to the ”LOCK” position and the nega-
tive (−) terminal cable is disconnected from the bat-
tery.
Store the front passenger airbag assembly with the
airbag deployment side facing upward.
(b) Using a service− purpose wire harness for the vehicle, tie
down the front passenger airbag assembly to the tire.
Wire harness: Stripped wire harness section
1.25 mm
2 or more (0.0019 in.2 or more)
HINT:
To calculate the square of the stripped wire harness section: Square = 3.14 X (Diameter)

SUPPLEMENTAL RESTRAINT SYSTEM FRONT PASSENGER AIRBAG ASSEMBLY
1996 LAND CRUISER (RM451U)
CAUTION:
If the front passenger airbag assembly is tied down with
too thin wire harness, it may snap. This is highly danger-
ous. Always use a wire harness which is at least 1.25 mm
2
(0.0019 in.2)
(1) Wind the wire harness around the tire, passing the wire harness through the installation holes indi-
cated by arrows in the illustration.
(2) Position the front passenger airbag assembly in- side the tire with the airbag deployment side 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 that the wire harness is tight. It is very dan-
gerous if looseness in the wire harness results in the
front passenger airbag assembly coming free due to
the shock from the airbag deploying.
Always tie down the front passenger airbag assembly
with the airbag deployment side facing inside.
NOTICE:
The tire will be marked by the airbag deployment, so use a
redundant tire.
(c) Check functioning of the SST. SST 09082−00700
(d) Place tires. (1) Place at least 2 tires under the tire to which the frontpassenger airbag assembly is tied.
(2) Place at least 2 tires over the tire to which the front passenger airbag assembly is tied. The top tire
should have the wheel installed.

(3) Tie the tires together with 2 wire harnesses.
CAUTION:
Make sure that the wire harnesses are tight. It is very dan-
gerous if loose wire harnesses result in the tires coming
free due to the shock from the airbag deploying.
HINT:
Place the SST connector and wire harness inside tires. Provide
at least 1 m (3 ft) of slack for the wire harness.
(e) Install the SST. Connect the SST connector to the front passenger airbag
assembly connector.

NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock.
(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) Confirm that no one is within 10 m (33 ft) area around the tire which the front passenger airbag as-
sembly is tied to.
(3) Press the SST activation switch and deploy the air-
bag.

The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.
(g) Dispose of the front passenger airbag assembly.
