Engine coolant level low

[TucanSpam]

i searched and looked at some topics, most people said to go to the dealer to get it put in because they have a premix? anyways does anyone know if i can do it without going to the dealer? like add it in my self, and does anyone know which type of antifreeze to get?

one more question, i reset my services lights myself, but if i go to the dealer, would they care if they found out/i told them? would it void my warranty? i wanted to get my x5 checked out by them for any problems before my warranty runs out in a couple of months.
