  • Change 72000 miles
  • Code: D6KF1-2 6/1

Additional Notes

  • Both the HEV and PHEV variants of the Kia Niro SG2 share an identical automatic transmission fluid capacity range of 1.6-1.7 liters, which is consistent with a partial drain-and-fill service rather than a full overhaul refill of the transaxle assembly.
  • The capacity range of 1.6-1.7 liters reflects the typical variation encountered during a service fill, where residual fluid retained in the valve body or passages accounts for the spread between the lower and upper figures.
  • Both configurations carry a service interval of 72,000 miles, and in both cases the specifications assign a severe use condition to that interval, meaning the 72,000-mile change figure applies specifically under severe operating conditions.
  • The semi-automatic transaxle noted for both the 1.6 GDI HEV and 1.6 GDI PHEV is a dual-clutch type unit adapted for hybrid powertrains, which is why fluid maintenance intervals and capacities are specified under the automatic transmission fluid category rather than a conventional manual transmission classification.
