SUMMARY: In April 2007@ the agency published a final rule establishing a new Federal motor vehicle safety standard on electronic stability control (ESC) systems for light vehicles. As part of that rulemaking@ the final rule notice stated that NHTSA had decided to defer the standard's requirements related to the ESC telltales and controls until the end of the phase-in period (i.e.@ until September 1@ 2011). Accordingly@ most of the paragraphs containing ESC telltale and control requirements were prefaced with the phrase ????as of September 1@ 2011.'' However@ that phrase was inadvertently omitted from two of the paragraphs setting forth ESC telltale and control requirements. These amendments correct this administrative error by adding the phrase ????as of September 1@ 2011'' to those paragraphs.
