ASSEMBLY OR WHEN LEAVING A LIVE AIR BAG
ASSEMBLY UNATTENDED ON A BENCH O
R
OTHER SURFACE, ALWAYS FACE THE AIR BAG
AND TRIM COVER UP AND AWAY FROM THE
SURFACE. THIS IS NECESSARY SO THAT A FREE
SPACE IS PROVIDED TO ALLOW THE AIR BAG TO
EXPAND IN THE UNLIKELY EVENT OF
ACCIDENTAL DEPLOYMENT. FAILURE TO
FOLLOW PROCEDURES MAY RESULT IN
PERSONAL INJURY.
6. Place the driver air bag assembly on a work bench
or other surface away from all loose or flammable
objects with its trim cover facing up, away from the
surface.

7. Clear a space on the ground about 183 cm (six
feet) in diameter where the driver air bag assembl
y
is to be deployed. A paved, outdoor location
where there is no activity is preferred. If an
outdoor location is not available, a space on the
shop floor where there is no activity and sufficien
t
ventilation is recommended. Ensure no loose or
flammable objects are within the deployment area.

be connected to a power source until the air bag is
to be deployed. The driver air bag assembly will
immediately deploy the air bag when a powe
r
source is connected to it.
NOTE: Ensure that the pigtail adapter is firmly seated
into the driver air bag assembly connector. Failure to
fully seat the connectors may leave the shorting ba
r
located in the driver air bag assembly connecto
r
functioning (shorted) and may result in nondeployment
of the driver air bag assembly.

Refer to “Passenger Air Bag Assembly Removal “.
6. Clear a space on the ground approximately 183
cm (six feet) in diameter where the fixture with
attached air bag assembly is to be placed fo
r
deployment. A paved outdoor location where
there is no activity is preferred. If an outdoo
r
location is not available, a space on the shop floor
where is no activity and sufficient ventilation is
recommended. Ensure that no loose o
r
flammable objects are within the deployment area.

r
intention to deploy the passenger air bag
assembly. The deployment will be accompanied
by a substantial noise which may startle the
uninformed.
15. Separate the two banana plugs on the SRS
deployment harness.
NOTE: When the air bag deploys, the driver air bag
assembly may jump about 30 cm (one foot) vertically.
This is a normal reaction of the driver air bag to the
force of the rapid gas expansion inside the air bag.
NOTE: When the air bag deploys, the rapid gas
expansion will create a substantial noise. Notify all
people in the immediate area that you intend to deplo
y
the air bag assembly.
WARNING: DEPLOYMENT HARNESS SHALL
REMAIN SHORTED AND NOT BE CONNECTED TO
A POWER SOURCE UNTIL THE AIR BAG IS TO BE
DEPLOYED. THE AIR BAG ASSEMBLY WILL
IMMEDIATELY DEPLOY THE AIR BAG WHEN A
POWER SOURCE IS CONNECTED TO IT.
CONNECTING THE DEPLOYMENT HARNESS TO
THE POWER SOURCE SHOULD ALWAYS BE THE
LAST STEP IN THE AIR BAG ASSEMBLY
DEPLOYMENT PROCEDURE. FAILURE TO
FOLLOW PROCEDURES IN THE ORDER LISTED
MAY RESULT IN PERSONAL INJURY.
16. Connect the SRS deployment harness wires to the
power source to immediately deploy the air bag
assembly. Recommended application : 12 volts
minimum, 2 amps minimum. A vehicle battery is
suggested.
17. Disconnect the SRS deployment harness from the
power source.
18.Short the two SRS deployment harness leads
together by fully seating one banana plug into the
other.
19. In the unlikely event that the passenger air bag
assembly did not deploy after following these

23. Verify that the inside of the vehicle and the area
surrounding the vehicle are clear of all people and
loose or flammable objects.
24. Stretch the driver and passenger deploymen
t
harness to their full length.
25. Completely cover windshield area and front doo
r
window openings with a drop cloth, blanket or
similar item. This reduces the possibility of injury
due to possible fragmentation of the vehicle's
glass or interior.
26. Notify all people in the immediate area that you
intend to deploy the air bags. The deployment will
be accompanied by a substantial noise which ma
y
startle the uninformed.
27. Separate the two ends of the driver deploymen
t
harness wires.
WARNING: DEPLOYMENT WIRES SHALL REMAIN
SHORTED AND NOT BE CONNECTED TO A
POWER SOURCE UNTIL THE AIR BAG IS TO A
POWER SOURCE UNTIL THE AIR BAG IS TO BE

30.Connect the passenger deployment harness wires
to a power source to immediately deploy the
passenger air bag assembly. Recommended
application: 12 volts minimum, 2 amps minimum.
A vehicle battery is suggested.(Driver air bag
assembly) Put on a pair of shop gloves and safet
y
glasses to protect your hands and eyes from
possible irritation and heat when handling the
deployed air bag assembly. After an air bag
assembly has been deployed, the surface of the
air bag may contain a powdery residue. This
powder consists primarily of cornstarch (used to
lubricate the bag as it inflates) and by products o
f
the chemical reaction. Sodium hydroxide dust
(similar to 30. lye soap) is produced as a b
y
product of the deployment reaction. The sodium
hydroxide then quickly reacts with atmospheric
moisture and is converted to sodium carbonate
and sodium bicarbonate (baking soda). Therefore,
it is unlikely that sodium hydroxide will be present
after deployment.(Passenger air bag assembly)
The passenger inflator requires no special
precaution after deployment. 95% of the
particulate emission are potassium chloride (KLC),
which is commonly sold as an edible salt-
substitutes. even if water is applied. Post
deployment products are relatively pH neutral.
Disposing the inflator by burying it in a landfill will
not products any hazardous products. As with an
y
dusty environment, safety goggles, dust mask and
gloves should be worn.
WARNING: SAFETY PRECAUTIONS MUST BE
OBSERVED WHEN HANDLING A DEPLOYED AI
R
BAG ASSEMBLY. AFTER DEPLOYMENT, THE
METAL SURFACES OF THE AIR BAG ASSEMBLY
WILL BE VERY HOT. ALLOW THE AIR BAG
ASSEMBLY TO COOL BEFORE HANDLING ANY
METAL PORTION OF IT. DO NOT PLACE THE
HOT DEPLOYED AIR BAG ASSEMBLY NEAR ANY
FLAMMABLE OBJECTS. FAILURE TO FOLLOW
PROCEDURES COULD RESULT IN FIRE O
R
PERSONAL INJURY.
After an air bag assembly has been deployed, the
metal canister and surrounding areas of the ai
r
bag assembly will be very hot. Do not touch the
metal areas of the air bag assembly for about 30
minutes after deployment. If the deployed air bag
assembly must be moved before it is cool, wea
r
gloves and handle by the air bag or trim cover.
31. Short the driver deployment harness wires b
y
twisting together one end from each. Repeat this
procedure for the passenger deployment harness.
32. Carefully remove drop cloth from vehicle and clean
off any fragments or discard drop cloth entirely.
33. Disconnect driver deployment harness and
passenger deployment harness from vehicle and
discard.
