Air Bag On-Off Switches

This document amends a final rule which allows motor vehicle dealers and repair businesses to install retrofit manual on-off switches for air bags in motor vehicles. The rule requires the on-off switch to be key operated and requires a telltale that indicates the operating status of the air bag. NHTSA has determined that the language of the regulatory text could be mistakenly interpreted to require a key specifically matched to the on-off switch and that the rule was ambiguous as to how the readiness indicator should function when one or both air bags have been deactivated by means of the on-off switch. This rule revises the language of the regulatory text to clarify these issues. It also corrects a clerical error found in the original regulatory text.
