Step by step
1Set the parking brake and rotate the canopy toward the handlebar.
2If the stroller has no built-in receivers, push the included R and L receivers onto the yellow pins behind the seat fabric until they click and green bars show.
3Push both end caps of the adapter straight into the receiver sockets until each side clicks, then pull the front tube to check it is locked.
4Recline the stroller seat and set the car seat on the adapter rear-facing and centered, lining up the car seat's carry-handle hinge with the receivers.
5Push the car seat straight down until both sides click.
6Lift up on each side of the car seat to check it is secure.
