I haven't been out to check, but, I'm 99% sure that when I climb in and power up I get an orange light/illumination around and on the left large auto A/C button that goes off when I press it to turn off.
Being that I leave auto A/C on all the time it comes on by default for me
Then it illuminates again when I press the same 'Auto' button
If I remember I'll pop out later, in these sub zero temps to check
