From FAQ section of Prestone Website:
"Some European automobile manufacturers request that a phosphate-free antifreeze be used in their vehicles. This issue is related to the extremely high mineral content of the water in Europe. If you were to mix an antifreeze that contained phosphates with the type of water they have in Europe, it may produce deposits that can settle in the cooling system and promote corrosion. However, in North America we do not have this type of water problem. Typical North American coolants have contained phosphates (which is part of the corrosion inhibitor package) for many years. Therefore, the question of phosphates is a non-issue here in North America. Prestone® Antifreeze/Coolant is completely safe for use in both foreign and domestic vehicles. For those consumers who would feel more comfortable using a phosphate-free antifreeze, our Prestone® LongLife® Premixed Antifreeze/Coolant and Prestone® Dex-Cool® Premixed LongLife® Antifreeze/ Coolant formula’s are phosphate, silicate, and borate free. These coolants use a special chemistry and technology that extends the life of the corrosion inhibitor package so that it lasts for five years or 240,000 kms (whichever comes first), and is safe for all cars and light trucks (old or new). Prestone® Dex-Cool® Premixed LongLife® Antifreeze/ Coolant has been approved by General Motors under their DEX-COOL® specifications and is compatible with other DEX-COOL® approved coolants. * DEX-COOL® is a registered trademark of General Motors Corporation."
if your vehicle is still under warranty, though, go to the stealer-ship and get the red fluid
