    I know that in normal operation, the Prius is not in full hybrid operation until certain requirements have been met:

    The engine is fully warmed up;

    AND

    The car has come to a stop for 10 seconds OR it has exceeded a certain speed (somewhere around 40 mph???)

    With these conditions met, the computer is in Phase III (or IV) operation.

    My question is, with the EV switch installed, must the computer be in this Phase III (IV) condition for EV mode to be engaged with the switch? Or is it sufficient that the engine be fully warmed up?

    To put it another way, can pressing the button be a substitute for the second criterium? That is:

    The car has come to a stop for 10 seconds OR it has exceeded a certain speed OR you engage the switch?

    The criteria for stage III must be met before the EV mode will engage. You cannot engage EV via the button in stage II.
