Living on the coast I find it comfortable on most days to use the vents rather than wasting energy on air conditioning. Even on fairly hot days I find AC is just not needed. I select Auto-off, AC-off, Heat-off and fan blowing as needed. This is fine however a few minutes after starting the car I realize it's cold, then I notice that the AC is on. So after a few drives it sinks in that the AC defaults to ON. This seems inefficient for a car that is should respect energy saving.
