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 the
front passenger airbag assembly with the deployed
airbag.

Always wash your hands with water after completing
the operation.

Do not apply water, etc. to the front passenger airbag
assembly with the deployed airbag.

When scrapping a vehicle, deploy the airbag and
scrap the vehicle with the front passenger airbag as-
sembly still installed.

When moving a vehicle for scrapping which has the
front passenger airbag assembly with the deployed
airbag, use gloves and safety glasses.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.
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-28).
CAUTION:

When removing the front passenger airbag assembly,
work must be started 90 seconds after the ignition
switch is turned to the ºLOCKº position and the nega-
tive (-) terminal cable is disconnected from the bat-
tery.

When storing the front passenger airbag assembly,
keep the upper surface of the airbag deployment side
facing upward.

(b) Using a service-purpose wire harness, 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)
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 in2.).
HINT:
To calculate the square of the stripped wire harness section:
Square = 3.14 X (Diameter)
2 divided by 4
(1) Pass the wire harness though the installation holes,
as shown 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 when
disposing of the airbag use a redundant tire.

(c) Check functioning of the SST (See step 1-(a) on page
RS-17).

(d) Place the tires.
(1) Place at least 2 tires under the tire to which the front
passenger 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 harness.
CAUTION:
Make sure that the wire harness is tight. It is very danger-
ous 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 connectors of the 2 SST to the front passen-
ger airbag assembly connector.
SST 09082-00700, 09082-00760
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 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 tire which the front passenger airbag assembly
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.
