AIR BAG (INFLATOR) MODULES DISPOSAL
WARNING:
Failure to follow proper air bag (inflator) module disposal procedures can result in air bag deployment
which may cause personal injury. Undeployed air bag (inflator) module must not be disposed of
through normal refuse channels.
The undeployed air bag (inflator) module contain substances that can cause severe illness or personal
injury if the sealed container is damaged during disposal.
Do not dispose of the live (undeployed) air bag (inflator) modules.
The method employed depends upon the final disposition of the particular vehicle, as noted in ªDeployment Out-
side Vehicleº and ªDeployment Inside Vehicleº in this section.
Deployment Outside Vehicle disposing of the air bag (inflator) module(s) only (i.e., the vehicle itself will be. . . . . .
used again).
Deployment Inside Vehicle scrapping the entire vehicle including the air bag (inflator) module(s).. . . . . . . .
DEPLOYMENT OUTSIDE VEHICLE
Use this procedure when the vehicle itself is used again (only the air bag (inflator) module(s) are disposed of).
WARNING:
Following precautions must be observed for this work. Failure to observe any of them may result in
personal injury.

To avoid an accidental deployment, this work should be performed by no more than one person.

The procedure should be followed strictly as described here.

Be sure to read ªService Precautionsº in this section for the air bag (inflater) module beforehand.

Never connect deployment harness to any power source before connecting deployment harness to
the air bag (inflator) module. Deployment harness shall remain shorted and not be connected to a
power source until the air bag is to be deployed.

Since a large amount of smoke is produced when air bag is deployed, select a well-ventilated area.

The air bag (inflator) module will immediately deploy the air bag when a power source is connected
to it. Wear safety glasses throughout this entire deployment and disposal procedure.

Wear suitable ear protection when deploying air bag. Also, advise those who are in the area close to
deployment site to wear suitable ear protection.

Do not deploy driver and passenger air bag (inflator) modules at the same time.
The following procedure requires use of special tool(s) (deployment harness and passenger air bag (inflator) mod-
ule deployment fixture). Do not attempt procedure without it (them).

17) Put on a pair of shop gloves to protect your hands from possible
irritation and heat when handling the deployed air bag (inflator)
module.
NOTE:
As a precaution, gloves and safety glasses are recom-
mended to prevent any possible irritation of the skin or
eyes.
18) Disconnect the deployment harness from the air bag (inflator)
module as soon after deployment as possible. This will prevent
damage to the deployment harness due to possible contact
with the hot air bag (inflator) module canister. The deployment
harness are designed to be reused. They should, however, be
inspected for damage after each deployment and replaced if
necessary.
19) Dispose of the deployed air bag (inflator) module through nor-
mal refuse channels after it has cooled for at least 30 minutes
and tightly seal the air bag (inflator) module in a strong vinyl
bag. (Refer to ªDeployed Air Bag (Inflator) Modules Disposalº
in detail.)
20) Wash your hands with mild soap and water afterward.
NOTE:
The remaining steps are to be followed in the unlikely event
that the air bag (inflator) module did not deploy after following
these procedures.
21) Ensure that the deployment harness has been disconnected
from the power source and that its two banana plugs have been
shorted together by fully seating one banana plug into the oth-
er.
22) Disconnect the deployment harness from the air bag (inflator)
module.

SEAT BELT PRETENSIONERS DISPOSAL
WARNING:
Failure to follow proper seat belt pretensioner (retractor assembly) disposal procedures can result in
pretensioner activation which may cause personal injury. Inactivated seat belt pretensioner must not
be disposed of through normal refuse channels.
The inactivated seat belt pretensioner contain substances that can cause severe illness or personal
injury if the sealed container is damaged during disposal.
Do not dispose of the live (inactivated) seat belt pretensioners.
The method employed depends upon the final disposition of the particular vehicle, as noted in ªActivation Outside
Vehicleº and ªActivation Inside Vehicleº in this section.
Activation Outside Vehicle disposing of the seat belt pretension(s) only (i.e., the vehicle itself will be used. . . . . . . .
again).
Activation Inside Vehicle scrapping the entire vehicle including the seat belt pretensioners.. . . . . . . . . .
ACTIVATION OUTSIDE VEHICLE
Use this procedure when the vehicle itself is used again (only the seat belt pretensioner(s) are disposed of).
WARNING:
Following precautions must be observed for this work. Failure to observe any of them may result in
personal injury.

To avoid an accidental activation, this work should be performed by no more than one person.

The procedure should be followed strictly as described here.

Be sure to read ªService Precautionsº in this section for the seat belt pretensioner beforehand.

Never connect deployment harness to any power source before connecting deployment harness to
the seat belt pretensioner. Deployment harness shall remain shorted and not be connected to a power
source until the pretensioner is to be activated.

The seat belt pretensioner will immediately activate the pretensioner when a power source is con-
nected to it. Wear safety glasses throughout this entire activation and disposal procedure.

Wear suitable ear protection when activating pretensioner. Also, advise those who are in the area
close to activation site to wear suitable ear protection.

Do not activate driver and passenger seat belt pretensioners at the same time.
The following procedure requires use of special tools (deployment harness). Do not attempt procedure without it.
