The RX450hL/RX350L provides a flat, gap-free luggage space, regardless of whether the third row seats are in use or stowed. The tonneau cover stores under the luggage space floor to provide ample room for luggage even when carrying seven people. Both the second row and third row seats have a split seatback design to enable different luggage configurations. The power folding third row seats are controlled by switches in the passenger side trim of the second row seats and in the left side of the luggage space.
