(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

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.
SST 09082−00700
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.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.
(g) 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) Remove the front passenger airbag assembly from
the tire.
(2) Place the front passenger airbag assembly in a vi- nyl bag, tie the end tightly and dispose of it in the
same way as other general parts disposal.
