Kia Niro, SG2 (EU)

Automatic transmission fluid capacity & service interval

Kia Niro, SG2 (EU) uses automatic transmission fluid with a capacity range of 1,6-1,7 liters. The service interval is 120000 km. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Kia Niro SG2 (EU) automatic transmission fluid specifications cover a semi-automatic transaxle unit, which is a combined transmission and axle assembly commonly found in hybrid drivetrains where the electric motor and gearbox share a single housing.
  • All four configurations listed carry a fluid capacity range of 1.6-1.7 liters, which is a relatively small volume consistent with a service fill rather than a full overhaul drain, where residual fluid typically remains in the torque converter or valve body.
  • The 120,000 km change interval applies under severe use conditions across every listed variant, meaning the interval is not a standard or normal-use figure but one already adjusted for more demanding operating circumstances such as frequent short trips, heavy traffic, or towing.
  • The 1.6 GDI Hybrid and 1.6 GDI Plug-in Hybrid variants spanning 2022-2024 share identical capacity and interval specifications despite differing in powertrain architecture, with the plug-in variant adding a larger battery and external charging capability to the same 1.6-liter GDI base engine.
  • The 95 kW output designation on the 1.6 GDI Hybrid variant introduced from 2024 onward distinguishes a specific power rating within the hybrid lineup, yet the transaxle fluid capacity of 1.6-1.7 liters and the 120,000 km severe-use interval remain unchanged from the earlier 2022-2024 hybrid specification.
  • The 126 kW plug-in hybrid variant introduced from 2024 onward represents the highest power output among the listed configurations, and despite the increased output, the semi-automatic transaxle fluid capacity and 120,000 km severe-use service interval are consistent with all other variants in the table.
