I wouldn't go by the handbook, personally I use only good quality (but no more than £5.70 a bottle) Liebfraumilch, preferably from south facing slopes, but hey, some times you have to slum it with north facing.
But if you prefer to stick by the rules of 'the man', this is from the PDF I have of the owner's manual...
It might be worth visiting your KIA dealer; I bought some OEM anti-freeze from them and it wasn't as expensive as I feared.
Now, back to my glass of Carplan BSA002...
