I'm in Canada but I can warm the seats when I remote start my car through the Kia UVO app. The app was included when I purchased the car and there was no charge for 3 years. They didn't know what would happen after. This is what it looks like.
I'm pretty sure the uvo app is available on the EX Premium and up.They have a special chip in the car that interacts with the app on your phone.That is what the dealer told me.Check with yours to confirm.
