Fllo MUST be installed with a Top Tether when forward-facing.
ALWAYS secure the Top Tether provided with this car seat when installing forward-facing with lap/shoulder belt unless no Top Tether anchorage is available.
If installing with a vehicle belt without a Top Tether, Fllo MUST be installed with a lap/shoulder belt.
NOTE: If unavailable, we recommend that you check with your vehicle manufacturer for the availability of retrofitting anchors into the vehicle. The Top Tether is a critical component in stabilizing forward-facing harnessed convertible seats and significantly reduces potential head, neck, and spinal cord injuries.
