> - No way to defrost your windshield, unless you're already driving
I have a 2022 Prius Prime, and I am moderately sure with the car on and in park I can press the front window defrost button, and the ICE will turn on and start blowing hot air on the front window.
Also, while parked and plugged in at home, I can use the remote A/C button to start heating the cabin and front windshield while clearing off snow and clearing the driveway, and will be powered from my house. I'm not sure if this also works without being plugged in.
