I take it when using just the Auto Climate the air con is off?
Do most people use Auto Climate AND the air con set to on?
I had the same question with my new Jazz
My understanding is that on "Auto" the system works truly automatic and turns AC on and off on its own at it sees fit with no
visual indication whether AC is on or off even when it is clearly using the AC.
In the past 15 months of ownership I've found that the systems works well on "Auto" without needing any intervention besides the occasional adjusting of the temperature setting.
Like so many other things in the Jazz the system seems to be well designed and does a good job!
I leave it all year on "Auto"
