G 1500 1/2 Ton Van V8-5.7L VIN R (1997)
^
Short the deployment harness wires as instructed.
^
Connect the deployment harness to the inflator module before you connect it to the power source.
^
Connect the deployment harness to the power source to immediately deploy the air bag.
Failure to follow the procedures In the order listed may result in personal injury.
NOTICE: The rapid gas expansion involved with deploying an air bag will be very loud. Notify all people in the immediate area that you in tend to
deploy the inflator modules.
33. Connect the driver deployment harness wires to the power source to immediately deploy the inflatable restraint steering wheel module (Figure 34).
34. Disconnect the deployment harness wires from the power source.
35. Separate the two ends of the passenger deployment harness wires (Figure 35).
36. Connect the passenger deployment harness wires to a power source. This will immediately deploy the inflatable restraint I/P module (Figure 35).
After the inflator module has 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 of the chemical reaction. The deployment reaction produces sodium hydroxide dust (similar to lye soap).
The sodium hydroxide quickly reacts with the atmospheric moisture. This atmospheric moisture converts the sodium hydroxide into sodium carbonate
and sodium bicarbonate (baking soda). Therefore, you will probably find no sodium hydroxide present after the deployment. Gloves and safety glasses
are recommended, however, as a precaution. Gloves and safety glasses help to prevent possible irritation of the skin or eyes.

CAUTION: Immediately following the deployment of an air bag, the metal surfaces of the inflator module are very hot. Do not place the
deployed inflator module near any flammable objects. Wait for about ten minutes before touching any metal surface of the inflator module.
Disregarding these precautions may cause fire or personal injury.
The metal canister and the area surrounding the inflator module are very hot. Do not touch the metal areas of the inflator module for about ten minutes
after deployment. If you must move the deployed inflator module, use caution. Always wear gloves and handle the inflator module by the air bag or the
vinyl trim (Figure 25).
37. Disconnect the deployment harness wires from the power source.
38. Short the driver deployment harness wires by twisting together one end from each of the wires together. Repeat this procedure for the passenger
deployment harness.
39. Carefully remove the drop cloth from the vehicle.
40. Disconnect the driver deployment harness and the passenger deployment harness from the vehicle.
41. Discard both deployment harnesses.
42. After deploying both air bags, you may scrap the vehicle in the same manner as a non-SIR equipped vehicle.
43. In the unlikely event that either or both of the inflator modules did not deploy after following these procedures, proceed immediately with Steps 44
through 46.
44. Remove the undeployed inflator module(s) from the vehicle.
CAUTION: When you are carrying an undeployed Inflator module:
^
Do not carry the inflator module by the wires or connector on the inflator module.
^
Make sure the bag opening points away from you.
When you are storing an undeployed inflator module, make sure the bag opening points away from the surface on which the inflator module
rests. When you are storing a steering column, do not rest the column with the bag opening facing down and the column vertical. Provide free
space for the air bag to expand in case of an accidental deployment. Otherwise, personal injury may result.
45. Temporarily store the inflator module with its vinyl trim cover facing up.
46. Call the Technical Assistance group for further assistance.
