Story time.......

I leave the office at 4pm, and the outside temp is 102*, (106* with the heat index). I got about 5 miles away from the office, and had just gotten on the freeway about 1 mile ago. All of a sudden, my imid pops up with "High Temperature - Power Reduced". I turn off the radio and the AC, and while deciding whether or not I should pull to the shoulder, it goes away. The warning didn't return the rest of the drive home. (I turned the AC back on a few minutes later too and still all good).

I now know that means the hybrid power system operating temperature is too high, and I should pull to the shoulder, turn off any power accessories and AC, put it in Park and apply E-brake, but leave it running, until it goes away.

But I'm still a tad confused. Does this basically mean that the hybrid battery in the trunk got too hot, (probably from sitting outside all day), and it just took a little bit of driving to heat up further, enough to trigger the alert? And I'm assuming about that same time, enough of the airflow from driving and various vents had reached it and cooled it down enough to acceptable levels?

No need to see the dealer, right? Is this common in high temps? Because if it is, Central Texas is horrid right now, and I'm hoping I won't be having to pull over every afternoon on the drive home.

....Is there anything in your manual that states what to do in this scenario? Honda is really good at telling you what each alert means.
Yea, I'm basically supposed to do exactly what I did, except I should have also pulled off the roadway and put it in P as well, but still leave it running.

I was actually rather disappointed in the manual. It basically just reiterates what the imid displays, that the system temps are too high and to park & allow it to sit while still on until the warning turns off. If the warning doesn't turn off, have it inspected by a dealer.

I suppose that's all well & good, but I'm the type of guy that wants to know 'why' it may be too high, thus finding ways to avoid it becoming too high in the first place. For example, if it said, "this may occur in high ambient temps in stop & go traffic", than I would try to avoid that situation and take the toll road.
