    IMPORTANT:
    • The rapid gas expansion involved with deploying an air bag is very loud. Notify all people in the immediate area that you intend to deploy the inflator module.
    • When the air bag deploys, the inflator module may jump about 30 cm (1 ft) vertically. This is a normal reaction of the inflator module to the force of the rapid gas expansion inside the air bag.
  18. Connect the SIR deployment harness wires to the power source.
