(f) Cover steering wheel pad with cardboard box or tires.

Covering method using cardboard box:
Cover the steering wheel pad with the cardboard
box and weight the cardboard box down in 4 places
with at least 190 N (20 kg, 44 lb).
Size of cardboard box:
Must exceed the following dimensions:
x=460 mm (18.11 in.)
When dimension of the cardboard box exceeds the di-
ameter of the disc wheel with tire which the steering
wheel pad is tied to±
x=460 mm (18.11 in.) + width of tire
y= 650 mm (25.59 in.)
NOTICE:
If a cardboard box smaller than the specified size is used,
the cardboard box will be broken by the shock from the air-
bag deployment.

Covering method using tires:
Place at least 3 tires without disc wheel on top of the
disc wheel with tire to which the steering wheel pad
is tied.
Tire size: Must exceed the following dimensions±
Width: 185 mm (7.87 in.)
Inner diameter: 360 mm (14.17 in.)
CAUTION:
Do not use tires with disc wheels.
NOTICE:
The tires may be marked by the airbag deployment, so use
the redundant tires.
(g) 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 disc wheel which the steering wheel pad 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.

CAUTION:
If a wire harness which is too thin or some other thing is
used to tie down the front passenger airbag assembly it
may be snapped by the shock when the airbag is deployed.
This is highly dangerous. Always use a wire harness for ve-
hicle use which is at least 1.25 mm
2 (0.0019 in2).
(2) Wind the wire harness around the mount brackets.
(3) 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 the wire harness is tight. It is very danger-
ous when a loose 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
the spare tire.
(c) Check functioning of SST.

(d) Install the SST.
Connect the SST connector to the front passenger airbag
assembly connector.
