Does the Frontier have to be top tethered past 40lbs?

The Frontier requires the use of the top tether in harnessed mode at 65 lbs. and up. It's generally recommended to always use the top tether with an appropriate tether anchor in the vehicle at any weight with any harnessed FF carseat to reduce head excursion. :)
