DISPOSAL
HINT:
When scrapping vehicles equipped with an SRS or disposing
of the side airbag assembly always first deploy the airbag in ac-
cordance with the procedure described below. If any abnormal-
ity occurs with the airbag deployment, contact the SERVICE
DEPT. of the DISTRIBUTOR.
CAUTION:
S
Never dispose of a side airbag assembly which has
an undeployed airbag.
S
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.
S
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
S
When deploying an airbag, perform the operation at
least 10 m (33 ft) away from the airbag assembly.
S
The side airbag assembly is very hot when the airbag
is deployed, so leave it alone for at least 30 minutes
after deployment.
S
Use gloves and safety glasses when handling side
airbag assembly with the deployed airbag.
S
Always wash your hands with water after completing
the operation.

DEPLOYMENT WHEN DISPOSING OF SIDE AIRBAG
ASSEMBLY
NOTICE:
S
When disposing of the side airbag assembly only,
never use the customer’s vehicle to deploy the air-
bag.
S
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–39).
CAUTION:
When storing the side airbag assembly, keep the upper sur-
face of the airbag deployment side facing upward.
(b)
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 in
2
. 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 in
2
.).
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:
S
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.
S
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.
(c)
Check functioning of the SST (See step 1–(a) on page
RS–16).
