How do I attach a Graco infant carrier to the stroller?

Recline the stroller seat back to its lowest position, then position the mounting notches over the tray and push down on the carrier until the attachment latch snaps into the tray. Next, push the stroller canopy forward to locate the restraint latches on each side, then push the canopy back and rotate the restraint latches until they snap the infant carrier into place. Verify the carrier is securely attached by pulling up on it. Only use a Graco SnugRide carrier with this travel system. (Pages 27-29)
