Fold, carry and reinstall.
The backrest folds down to reduce bulk for transport, and an integrated handle makes the seat easier to carry. Remove the cup holder and release the anchors before folding, as described in the manual. At every new installation, fully unfold the seat and complete the required checks.
Clear checks for vehicle attachment.
Rigid UAS connectors have red-to-green indicators to check their attachment to the vehicle anchors. The manual also requires pulling on the booster to confirm attachment. UAS holds the booster in place; the vehicle’s lap-and-shoulder belt always restrains your child. The manual also permits use without UAS under the specified conditions.
