Sell my Prius people here's my question for you are most of you people leave car . Do you just hit the power button with the air conditioning and the stereo and everything running full tilt to ined off or shut off individual components stereo air etc ????
Just the big ol' power button for me. Unless I'm not sure I'll want the stereo blasting full tilt the next time I get in.
Power off only. However, I usually shut the AC down, but not the fan, a minute or so before stopping to dry out the evaporator a bit before parking it for the day.
+1 on turning A/C off but letting fan blow outside air through HVAC system, especially if it is humid outside.
