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.

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.

iii) Fill plastic reservoir in fixture (special tool) with water or sand.
This is necessary to provide sufficient stabilization of the fix-

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.
