ii) Clear a space on the ground about 185 cm (6 ft) in diameter
where the driver air bag (inflator) module is to be deployed.
A paved, outdoor location where there is no activity is pre-
ferred. If an outdoor location is not available, a space on the
shop floor where there is no activity and sufficient ventilation
is recommended.
Ensure no loose or flammable objects are within the deploy-
ment area.
ii) Place the driver air bag (inflator) module, with its vinyl trim
cover facing up, on the ground in the space just cleared.
[In case of Passenger Air Bag (Inflator) Module]
iii) Clear a space on the ground about 185 cm (6 ft) in diameter
where the fixture (special tool) with attached air bag (inflator)
module is to be placed for deployment. A paved outdoor loca-
tion where there is no activity is preferred. If an outdoor loca-
tion is not available, a space on the shop floor where there is
no activity and sufficient ventilation is recommended. Ensure
that no loose or flammable objects are within the deployment
area.
iii) Place special tool (passenger air bag (inflator) module de-
ployment fixture) on the ground in the space cleared in step
i), if it has not already been placed there.
Special Tool
(B): 09932-75040
iii) Fill plastic reservoir in fixture (special tool) with water or sand.
This is necessary to provide sufficient stabilization of the fix-
ture during deployment.
iv) Securely attach the passenger air bag (inflator) module in the
fixture (special tool) using mounting attachment, hold-down
bolts and nuts and M8 bolts and nuts.
CAUTION:
Be sure to use the following bolt and nut for fixing pas-
senger air bag (inflator) module to mounting attach-
ment. Size: M8, Strength: 7T
Passenger air bag (inflator) module must be mounted so that
the bag will deploy upward. Securely tighten all fastener prior
to deployment.

6) Pull out the webbing fully as shown at the left and cut it at the
root of the pretensioner (retractor assembly) as shown in the
figure.
WARNING:
As the drum of the retractor assembly turns very quick-
ly as soon as the webbing is cut, fix the retractor assem-
bly with a vise on the workbench and keep your hands
and fingers away from it when cutting the webbing.
7) Clear a space on the ground about 185 cm (6 ft) in diameter
where the seat belt pretensioner is to be activated. A paved,
outdoor location where there is no activity is preferred. If an out-
door location is not available, a space on the shop floor where
there is no activity and sufficient ventilation is recommended.
Ensure no loose or flammable objects are within the activation
area.
8) Place the seat belt pretensioner as shown in the figure on the
ground in the space just cleared.
9) Stretch the deployment harness from the seat belt pretension-
er to its full length 10 m (33 ft).
10) Place a power source near the shorted end of the deployment
harness. Recommended application: 12 Volts minimum, 2
amps minimum. A vehicle battery is suggested.
11) Verify that the area around the seat belt pretensioner is clear
of all people and loose or flammable objects.
12) Verify that the seat belt pretensioner is placed as shown in the
figure on the ground in the space just cleared.
13) Connect the seat belt pretensioner harness to the deployment
harness connector and lock the connector with lock lever.
