When I came to my parked and charging car today I noticed there was a light turned on inside the Hyundai logo. I can't find anything about this in the manual, what is it? I can't remember ever seeing this light before and I've had the car for 6 months. The car was charging and the remote heating was on, but it's not the first time the car has been charging or had the remote climate on. I saw this circle inside the logo before and I thought it was some kind of sensor.
