Federal Motor Vehicle Safety Standards; Transmission Shift Lever Sequence, Starter Interlock, and Transmission Braking Effect

This document proposes to amend the starter interlock requirements of Federal Motor Vehicle Safety Standard No. 102 to permit a vehicle's engine to stop and restart automatically after the driver has initially started the vehicle. The amendment would facilitate the development of propulsion systems, such as hybrid/electric systems, that conserve energy and reduce emissions by stopping the engine (internal combustion engine) when it is not needed. To prevent inadvertent vehicle motion in reverse gear that may result from a driver shifting error, the proposed amendment would allow a propulsion system to start and stop automatically in reverse gear only if the system exhibits, at least, a minimum "creep force" when the engine is stopped.
