Over the past 60 years, safety has been and will continue to be our priority at Graco. As part of Graco’s continuous process of reviewing the quality of its products, we have discovered an omission in the owner’s manual included with select Graco Highback and Backless TurboBooster car seats manufactured between December 22, 2015 through April 5, 2016. The owner’s manual omitted the consumer directive to secure the booster seat (when not in use) to the vehicle seat using the vehicle seat belt to prevent the car seat from striking other occupants in the event of a crash. Although this information does not affect the overall dynamic performance of the TurboBooster car seat if used according to instructions, it is required by the National Highway Traffic Safety Administration (NHTSA) FMVSS-213 standard. As such, Graco is proactively recalling the manuals included with the affected TurboBooster car seats. This affects only a small number of car seats produced by Graco and distributed in the United States.
