I've double checked the russian owners manual and USA too - same information. hour, minute and round nearest buttons only... Unfortunately, it's usless to ask russian dealers about such details:
- the sales of ct200 just starts here (fall april)
- russia got limit of 600 ct200 on 2011, due to hybrids unpopular here.
So, our dealers totally unprepared - there is absolutely no accessories, i'm still don't know the price of regular service maintance, etc....
I'm going to write the email to the toyota motors russia and ask them, so i will publish answer here.
It is not possible to switch to 24hour mode. If you look at the number to the far left (nr "1" in "12") you see that there isnt possible to make it a "2".
And since it cant display other than 1, there cant be a 24-hour clock mode.
Sad, I would also like to have it, but it seems to be impossible.
