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.
- blacksmith_tb 2y agoCan confirm, I have a 2017 Prius Prime, I keep it set to prefer all-EV driving, but I just got in and turned on the defroster to melt some frost off the windshield, it switches on the ICE engine. My only complaint is that it is not terribly smart about turning it back off during the same session of driving, if I turn off the defrost. I think in theory the heat pump would be able to provide the heat to do the job, but it'd use the charge in the traction battery up quickly...
- rssoconnor 2y agoIt has been my experience that if the ICE engine in the Prius Prime switches on for the first time for any reason, it prefers to remain on for several minutes at a minimum, no matter what. I have a theory for why this happens, but it is purely speculation on my part.
