NOTICE: The rapid gas expansion involved with deploying an air bag will be very loud. Notify all people in the immediate area that you intend to deploy the inflator modules.
59. Connect the SIR deployment harness wires to the power source to immediately deploy the inflatable restraint steering wheel module (Figure 50 with Frontal SIR system only or Figure 52 DeVille Model Only).
60. Disconnect the deployment harness wires from the power source.
61. Separate the two ends of the passenger frontal deployment harness wires (Figure 51 with Frontal SIR system only and Figure 53 DeVille Model Only).
62. Connect the passenger frontal deployment harness wires to a power source. This will immediately deploy the inflatable restraint I/P module (Figure 51 with Frontal SIR system only and Figure 53 DeVille Model Only).
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. As a precaution, gloves and safety glasses are recommended. Gloves and safety glasses help to prevent possible irritation of the skin or eyes.
63. Disconnect the deployment harness wires from the power source.
64. Follow steps 65 through 70 if the vehicle has side air bags (DeVille Models Only). If the vehicle does not have side air bags, go to step 71.

69. Connect the SIR deployment harness wires to the power source to immediately deploy the inflatable restraint side impact inflator module (Figure 53).
70. Disconnect the deployment harness wires from the power source.
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. As a precaution, gloves and safety glasses are recommended. 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 36).
71. Short the driver frontal deployment harness wires by twisting together one end from each of the wires together. Repeat this procedure for the passenger frontal deployment harness. Short the driver door and passenger door side air bag deployment wires if the vehicle has side air bags (DeVille Models Only).

73. Disconnect the driver frontal deployment harness and the passenger frontal deployment harness from the vehicle. Disconnect the driver door and passenger door side air bag deployment harnesses if the vehicle has side air bags (DeVille Models Only).
74. Discard the deployment harnesses.
75. After deploying the air bags, you may scrap the vehicle in the same manner as a non-SIR equipped vehicle.
76. In the unlikely event that an inflator module did not deploy after following these procedures, proceed immediately with Steps 77 through 79.
77. Remove the undeployed inflator module(s) from the vehicle. For the inflatable restraint steering wheel module refer to Inflator Module in SIR Steering Wheel and Column.
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.
78. Temporarily store the inflator module with its vinyl trim cover facing up.
