    New owner here. Love the car and have some questions. I believe these things are OK but just want to confirm:

    1. While in driving gear and in motion, press the button to switch b/w HV / EV / EV Auto.
    2. Also while driving, press the button to switch b/w Eco / Normal / Power modes.

    I think some users mentioned that they switch b/w HV / EV based on driving situation, so I guess it must be OK? Just want to know if it's going to hurt anything at all.

    Thanks!

    You will notice difference in accelerations and responsiveness among the various modes. But no the car is not going to "break" just playing with those buttons since the computer makes the transitions smooth.

    Thanks! BTW someone mentioned press and hold HV/EV button will force charging? Is that right? I couldn't find it in the manual.

    You might want to register with Toyota Owners Official Web Site with your VIN number, and then you can download PDF versions of the manuals. Then it is easy to search electronically for terms...

    There should be a manual available online. They usually go for on ebay anyways :)

    Thanks for posting that. I thought it must be possible but had not found it yet in the manual.

    It's all software.

    In HV mode the car is constantly switching the ICE on and off (it's always doing some sort of electric drive at a minimum just to engage the sun gears in the transmission even if the ICE is on).

    those buttons just change the pedal mapping (echo/normal/pwr, the ac settings (echo/others)) and how and when the ICE comes on (hv vs ev vs ev auto). All of that is controlled by the computer and those buttons are simply inputs to the computer. The computer is ultimately the thing that decides what to run and where and these are just settings, but ultimately it's all up to the computer.
