Babies have weak neck and back muscles that need extra support when traveling in a vehicle. A rear-facing infant seat will support your baby's head and neck in a sudden stop or a crash. Be sure you use a rear-facing infant seat that fits your baby's weight and height. Use it correctly in the rear-facing position, in the back seat, every time your baby rides in the car.
Rear-facing infant seats are available as infant- only seats, infant/child seats, or infant/child/ booster seats.
An infant-only seat is designed only for use as a rear-facing infant seat.
An infant/child seat or an infant/child/booster seat can be used as a rear-facing infant seat. Later, these seats can be used as forward-facing child seats when it is the right time to have the child ride facing the front of the vehicle. See Car Time – Stage 2 for more information about forward facing child seats.
Rear-facing infant seats have different upper weight limits. Check the label on the rear-facing infant seat for the weight and height that are allowed by the manufacturer.
Don't be in a hurry to start using a forward-facing child seat. The longer you use a rear-facing infant-only seat, infant /child seat, or infant/child/booster seat that fits correctly, even past your baby's first birthday, the safer your baby will be in a crash. Be sure to follow the manufacturer's instructions for use and check the label for the weight and height that are allowed.
Car seats manufactured after September 1, 2002 have two UAS connectors that attach to the UAS anchor bars in newer vehicles.
Check the vehicle owner's manual for the seating positions that can be used with UAS.
You may need to thread the UAS webbing strap through the infant/child seat or the base of the infant-only seat.
Attach the two UAS connectors to the UAS anchor bars and tighten the strap.
The rear-facing infant seat should not move more than 2.5 cm (1 inch) from side to side or forward.
Items not provided by the car seat manufacturer such as liners, trays, or comfort straps may interfere with the safety of the seat. Check with the car seat manufacturer before using these products with the baby's car seat.
