Graco infant car seats come with a base used for easy car installation, but sometimes an infant car seat is used without the base. This is considered safe and legal, but must be done according to Graco's installation instructions to keep your baby as safe as possible. If a car seat is not installed correctly, the results could be deadly. All caregivers who transport your infant should be trained on correct car seat installation techniques. An infant should ride in a rear-facing infant car seat until she is at least one year old and weighs no less than 20 lbs.
Set the infant car seat in the back seat. Position it so it is rear-facing.
Thread the lap belt seatbelt through the designated car seat slots and buckle it. The seat belt rests above your baby's legs. It should not be twisted or slack.
Tighten the seat belt. Kneel or push down on the car seat as you tighten the belt. The car seat should be snug against the back seat.
Look at the car seat level guide. If there is orange showing in the level guide, roll up a small towel or blanket and place it under the car seat where the vehicle's seat back meets the seat. Adjust the car seat and seat belt until the seat is securely installed and there is no orange in the level indicator.
Push down on the top of the car seat and make sure it does not tip or loosen the seat belt.
Wiggle the car seat side to side. There should little to no movement. If the car seat moves easily, tighten the seat belt.
