(b)

Fix the front passenger airbag assembly.
(1)

Use a service–purpose wire harness tie down the
front passenger airbag assembly.

Wire harness: Stripped wire harness section
1.25 mm

2

or more (0.0019 in

2

or more)

HINT:
To calculate the square of the stripped wire harness section:
Square = 3.14 x (Diameter)

2

divided by 4

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 in

2

).

(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.

(e)

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 tier
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 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)

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.

(g)

Dispose of 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 the deployed airbag.

Always wash your hands with water after completing
the operation.
