Certain child booster seat do not comply with the requirements of CMVSS 213 which states that the minimum weight for use must be 18 kg (40 lb). These units include a tag attached to the cloth pad that indicates a minimum weight for use of 13.7 kg (30 lb). Should an underweight child be placed in the booster cushion and the vehicle is involved in a crash, the child may have a greater risk of injury. Correction: Evenflo will notify registered owners and request that the incorrect tag be removed and discarded.
