    Probably an obvious answer but I am stumped. On the "HV System Indicator" display there are two arced lines. The narrow blue-green line is battery pack current, both charge and discharge. The wider blue line is the question: What is that wide blue line indicating?

    The green line is the power requested. The blue line is the suggested power request for efficient driving. The first half that’s shown with the lines and the “EV” lead car is the “Hybrid Eco” area, the most efficient area (generally. Not in all cases but generally).

    The blue zone is displayed in the Eco area which can be used as a reference. See clip from the oper manual.

    That was exactly what I was looking for, turns out to be a recommendation.
    Like your list of cars owned. Mine '73 MGB, Skoda, Rabbit diesel, '90 Civic, '99 Miata, '00 CR-V (last manual), '18 Prius: still have Miata and Prius.
