    Now you've got me doubting myself re the effect of EV City (speed or acceleration related). Let me pay it particular attention tomorrow and I'll come back to you.

    Its mainly for city traffic for fast up to speed without letting the ICE kick in as easy feels like 80-90% throttle is needed before the ICE kicks in. EV-CITY can't be used with cruise control that will turn that mode off. At least that's how it is in Sweden but think its the same on all European plugins.

    So you're saying cruise kicks you out of EV-City mode... Correct?

    Anyone have Toyota Electrical schematics for European version car? I can figure out mod (if possible) .... but need wiring diagram as given by Toyota.

    I can't see how wiring diagrams would help. I would assume that it is just different firmware in the engine control computer that implements the behavior (unless there is some super proprietary configuration parameter that can be tweaked to switch between "POWER" and "CITY" behavior).

    OK, back having paid closer attention to the functioning of EV City.

    When active, this setting won't let you go into the power band on the display. Acceleration is initially quite lively, but does tail off as speed gets higher. I've experienced this previously when trying to pass another vehicle on a dual carriageway - it got rather embarrassing until I admitted defeat and clicked out of EV mode completely.

    Oh my god.
    Do you have some sort of OBDII monitor or dongle? Can you see what codes are set to activate this mode?
    I would kill for EV without PWR. Emergency situations be damned.

    Now we are getting serious ... and in my situation pure EV is exactly what I want to apply. Lets find out how to do this... thanks!

    Alternatively, the ECU could support both via separate pins and the only difference is which pin gets wired to the button.

    Oh dear, I think I may have started an outbreak of Euro PiP envy...

    I'm sorry guys but I don't have any diagnostic tools at all so I'm not going to be much help :(

    I wonder if this linky might be of any use: Prius Plug-in launch – questions please! « Toyota UK news, reviews, video and pictures

    It's where T UK opened up a blog pre-launch, which in time became a set of Q&As - might be worth a punt?

    Either that, or the dealer local to my home has a particularly helpful tech manager called Andy who I met the other day - who might be able to assist? About Us | Inchcape (Oxford)

    If you wanted I could drop him a line, or perhaps your local dealers could contact T UK - it seems really odd that you guys have the Power function on Toyota's flagship economy vehicle when City mode is readily available.

    Hope assists, let me know.

    Oh, and if it's any consolation I CANNOT get EV Boost on mine - and believe me I've tried (and tried).

    That's what I am hoping for, similar to the ev button in the old Gen II version...

    Please do follow up with your dealer and let us know what he says. The dealers here are useless and certainly none would ever bother reaching out to T UK, as you call it :)

    Just put a wooden block under the pedal with a safety line attached for emergency acceleration. Red line and handle with appropriate usage warnings in English and Spanish of course.

    I would kill for city button in place of power button. I get incredibly annoyed when I accidentally push barely too hard and activate the ICE on a hill.

    That's a basic part of the design. It's automatic too.

    The first minute of engine warm-up being above 50 MPG confirms it.

    John, pretty sure the point here is that the euro-spec PHV doesn't have this mode. Just as the US-spec PHV doesn't have a city mode.

    If we did, then driving at 62mph in EV on a straight level road with an indicated 5+ miles left on the battery should mean that I get battery boost, AIUI, and the battery range should gently tick down.

    That simply doesn't happen in my car, the range stays resolutely the same, and I don't get the huge mpg figures I've seen in videos of US spec vehicles.

    ...unless I've misunderstood?
