Setup and Installation
The Clek Fllo Convertible Car Seat supports both rear-facing and forward-facing installations. Proper installation is crucial for safety.

- Steel Anti-Rebound Bar: Attach the steel anti-rebound bar as instructed in the full product manual. This bar helps prevent rotation of the car seat in a collision, enhancing safety.

- Refer to your vehicle's owner's manual for proper top tether anchor locations.
- Ensure the car seat is snug against the vehicle seat back and does not move more than one inch side-to-side or front-to-back at the belt path.
3-Across Seating

Securing Your Child
The Clek Fllo uses a 5-point harness system to secure your child.
