2. DEPLOYMENT WHEN DISPOSING OF SIDE AIRBAG
ASSEMBLY
NOTICE:
When disposing of the side airbag assembly only,
never use the customer's vehicle to deploy the air-
bag.
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 seatback assembly (See page RS-42).
(b) Remove the side airbag assembly from the seatback as-
sembly.
(1) Remove the hog rings.
(2) Release the seatback cover hook from the seat-
back frame.
(3) Remove the 2 bolts and side airbag assembly.
CAUTION:
When storing the side airbag assembly, keep the upper sur-
face of the airbag deployment side facing upward.
(c) Using a service-purpose wire harness, tie down the side
airbag assembly to the tire.
Wire harness: Stripped wire harness section
1.25 mm
2
or more (0.0019 in2. or more)
CAUTION:
If a wire harness which is too thin or some other thing is
used to tie down the side airbag assembly, 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 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) 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.
(3) Position the side airbag assembly 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 very danger-
ous when a loose wire harness results in the side air-
bag assembly coming free due to the shock from the
airbag deploying.
Always tie down the side 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.
(d) Check functioning of the SST (See step 1-(a) on page
RS-17).

ous when loose wire harness results in the tires coming
free due to the shock from the airbag deploying.
HINT:
Place the SST connector and wire harness inside tires. Secure
at least 1 m (3 ft) of slack for the wire harness.
(f) Install the SST.
Connect the connectors of the 2 SST to the side airbag
assembly connector.
SST 09082-00700, 09082-00750

(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 side 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.
(h) Dispose of the side airbag assembly.
CAUTION:
The side 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 side
