How do I switch the stroller from toddler seat mode to carriage mode?

First, fully recline the seat using the recline strap adjuster, then lift the handle and rotate the seat down. Press down on the inside of the toddler seat to flatten it out, and unfasten the buckles behind the leg rest under the seat. The buckles must remain unfastened before placing a child in carriage mode. (Pages 13–14)
