Make sure the bubble level falls between the two lines for the booster installation mode of use. Readjust the recline as necessary.

While pushing down on the seating surface of the car seat, pull the end of the lower anchor strap until both straps are tight.

Check installation.

Loosen, unbuckle, and store away the 5-point harness into the storage compartment in the seat back. Store the harness buckle into the storage compartment in the seat bottom.

Make sure your child is positioned correctly in the seat with their back flat against the backrest. Adjust the headrest position to fit your child correctly, ensuring the shoulder belt guide is positioned at or just slightly above the child’s shoulders.

Route the lap-shoulder belt across the child’s hips and chest, then buckle the vehicle belt.
