You want a P-HOAT coolant, which is the OEM chemistry. Kia/Hyundia aren't very specific in the owners manual about which coolant to use, but obviously coolant from the dealer would be the EXACT coolant per your question.
FWIW, I use this stuff as the color matches the OEM coolant. There are other P-HOATs out there that would work, but the Pentofrost is the exact color (dark green) that came in my Kia. I have heard reports of newer Hyundai / Kia vehicles getting a blue coolant as factory fill, but I've not seen one myself. If that's the case, Pentofrost A3 is colored blue.
