FWIW there is a definite way to “start” the AC to run before you exit the car, to ensure your passenger (*human, animal, or otherwise) stays comfortable. You have to put the car in park, first. Then you press the climate menu (tap the temperature at the center/bottom of big screen). Then at the top of screen you tap the 2nd item in the header (forget what it says/called; “climate timer” maybe?) and then from there a big start/turn-on button mid-screen is available but only if the vehicle is in park/stationary. That will then run for a bit— this will be useful for those of us in cold climates as the winter comes up, so keep the car toasty while you’re in a store/grocery for 20 to 30 mins etc—
