I had a chance today to try out the rear heating in my Largo. I forgot to check that the rear heating worked when I bought my van. I got the remote out of its little black case (very posh) and when I looked at it I noticed that the symbols were all in Japanese.
Now as I am somewhat of a language expert (well I can understand my wife and and I am sure she speaks a foreign language to me sometimes) It didn't take long to work out what all of the buttons did and surprise, surprise it works perfectly. Nice cold air blows out when on A/C and warm air when the control is set to a higher temp. Of course you have to press the RR button on the heating control panel in the front of the car first.

I was a little worried about the rear heating after hearing about other owners having problems with theirs but I need not have worried as all works fine.
