I would think that after a complete and thorough flush with distilled water you could use any AMAM OAT coolant like PEAK 10X or Prestone without any issues.
The textbook answer for a 2014 should be OAT coolant meeting Material Standard MS-12106/MS-90032 (purple). Fully agree with pbm, though. This summer I'm emptying my entire system and replacing with Prestone All-Vehicles 10 yr/300K OAT-compatible coolant.
