Whenever working near any of the SRS components, such as the impact sensors, the air bag module, steering column and instrument panel, disable the SRS. Handling of the SRS components requires extreme care. Special tools are also required. If in doubt, see a qualified service technician to ensure proper removal and installation of air bag system components.
