The A/C had THREE condtions.

One is of course A/C, indicated by the legend "A/C' on the tp right corner of the display.

Second is "Econ", obtained by pressing the "6" button for the Nav/multipurpose panel. It is indicated by the legend "ECON" on the top right corner of the display. This does NOT turn the compressor off. Rather, it puts it into a low ourput status, wherein the compressor doesn't work at full capacity.

Third is COMPLETELY off. To get to this, press the "6" button TWICE. The indicator then goes blank.

If the outside temp is moderate, choosing "ECON" will produce refigerated cold air, even with the temp set fairly high.

To get warm or heated air with the compressor off, one must select the compressor completely off setting, where the indicator is blank by pressing the "6" button twice. The heat function works properly then.

After trying to get warm air on cool mornings, I took the car in to the dealer and had them check it out. They said it worked fine. So, I had to resort to the dreaded "RTFM". Sure enough, if you look carefully, it's right in there. It's just not readily apparent unless you read the whole section in the owner's manual.
