Harness Mode (25-90 lbs)
For younger children within the specified weight and height limits, use the 5-point harness system. Ensure the harness straps are snug against your child's body and the chest clip is at armpit level.

Booster Mode (40-120 lbs)
As your child grows and meets the minimum requirements for booster mode, the 5-point harness can be stored within the seat. The car seat then functions as a belt-positioning booster, using the vehicle's seat belt to secure your child.
