I'd like to nominate this as a top-rated article in the Knowledge Base, but I don't see how to post a rating. Noting that no one else has rated any of the KB articles, I seem to be in good company.

Very much liked this quick tutorial on the stages of operation.

Hello all,

I agree this article is very good.

I would like to report that we, Japanese mileage freaks, found new stage called Stage-1B.

daniel wrote...
You cannot enter EV mode while in Stage 1.

However, you can enter EV mode if you have EV switch by following process when outside temperature is higher than 0C(32F) and your battery level is 6 or higher.

1. Push "START" on your vehicle.
2. Keep vehicle in "P" mode, the ICE will run for warming up after 10-15 seconds from pushing the "START" button.
3. Watch your energy screen on MFD, and you'll see a green arrow for charging.
4. After 56 seconds since starting engine, you'll see charging is now stopped.
5. Engage the EV switch and ICE stops, now you're in Stage-1B.

You should use ICE for accelerating by EV switching OFF, then you can enter EV mode for coasting and stopping at signal by EV switching ON.
It is very efficient warming up to run ICE only on accelerating until Stage-2.

Hope daniel will add this stage on the article.

Regards,
Ken@Japan

How easy is the install?
Can anyone post a pdf of the instructions?

Here's all you need to know:

Difficulty...about an 8 out of 10.
I'm not sure of the .pdf instructions, but I do remember printing it all out with pics, from somewhere. I guess doing a search here on 'EV button' would surely get u the .pdf file. I absolutely love the mod, enables a nice added feature that other hybrids don't have (at least here in the US).

Re: Mode 1B -- neat!

Boy, I wish I had an EV switch in my car to try this out. I don't see any reason why it would be different in the US -- same software.

Can anyone with the OEM or CoastalTech EV switch confirm Ken's observations?

Thanks for contributing this, Ken!

I think the 1B thing is an interesting find, but of little practical use. Why sit still in Park running the ICE for almost a full minute...what a waste.

FWIW, the comments about accelerating with ICE and then using EV for slow coasting and at a stop is pretty much what I do.
