The Evenflo LiteMax and SafeMax infant car seats have a weight range of 4 – 35 lbs (1.8 – 15.8 kg) and a height range of 17 – 32 inches (43 – 81 cm). It is important to always follow the information provided in the car seat instruction manual when installing and using your car seat.  However, to help meet the needs of families with very small infants, the Evenflo LiteMax and SafeMax infant car seats may be used with a smaller infant as indicated below:  Weight: 3 – 35 lbs (1.4 – 15.8 kg)  Height: 15.75 – 32 in (40 – 81 cm)  This update is a retroactive change to existing Evenflo LiteMax and SafeMax infant car seats. The following guidelines must be followed when using this car seat between 3 – 4 lbs (1.4 – 1.8 kg) and 15.75 – 17 in (40 – 43 cm):  The infant’s clinical team must approve of use and fit. Evenflo recommends following the AAP guidance and conducting an angle tolerance test prior to discharge. (Pediatrics 2009; 123: 1424-1429; reaffirmed June 2018).  Harness is positioned at or below the infant’s shoulders.  There is no gap between the child and the buckle.  Chest clip is positioned at armpit level.  Harness must be snug.  Date of manufacture 1/1/2018 or newer – infant insert is OPTIONAL for child fit.  Date of manufacture 12/31/2017 or older – infant insert is REQUIRED for infants who weigh between 3 – 4 lbs (1.4 – 1.8 kg) and OPTIONAL for infants who weight over 4 lbs (1.8 kg).  Travel should be limited to only what is necessary. It is recommended to have an adult observing the infant in the back seat and conducting frequent rest breaks during travel.  The head pillow, harness covers and buckle pad are OPTIONAL for all LiteMax seats, regardless of the date they were manufactured. As with any child using a child restraint, please ensure that all the other requirements set forth in the instruction manual for the child restraint are met.
