Here's what my 2009 Accent's manual says:
"Use only high quality, aluminum compatible, ethylene glycol antifreeze that conforms to SAEJ1034/ASTMD3306 specifications with high anhydrous sodium silicate content."
So, is that just plain old Prestone? The first replacement interval is 96000kms (60000mi) or 60 months, then every 48000kms (30000mi) or 24 months. Unlike my Honda vehicles, it does not specify to use "Hyundai" coolant.
