When I started using the heater on my Granturismo in November when the weather got cold, I realized that there is a bug in the heater system. Once in a while, the heater system just turns on automatically to the full auto setting (6 bars). Sometimes it is random.. and sometimes it seems like it turns on when the car temperature hits 0~2 degrees Celsius. Can't really tell. I've been too lazy to read the manual, so I'm not sure if this is due to an actual setting for the car. But, my intuition tells me its an electronic bug in the system. Anyone know what's up?
