Seat Mii, KF1 (EU)

Additional Notes

• All three engine variants of the Seat Mii KF1 share an identical manual transaxle fluid capacity range of 1.1 to 1.3 liters, which is characteristic of a compact integrated gearbox and final drive unit rather than a separate transmission housing.
• The capacity figure is expressed as a range rather than a fixed value, which reflects the typical difference between a drain-and-refill service fill and the variation introduced by residual fluid left in the unit during a standard service.
• The Mii 1.0 (44 kW) covers the full 2011-2020 model year span in the specifications, while the 1.0 (55 kW) variant runs from 2011-2019, and the 1.0 EcoFuel (50 kW) is listed from 2012-2020.
• The EcoFuel variant, which runs on compressed natural gas, shares the same 1.1-1.3 liter transaxle capacity and 12 months/30,000 km check interval as the petrol-powered versions, indicating no differentiation in transmission servicing requirements between fuel types.
• The service interval for all three variants is specified under normal use conditions at 12 months or 30,000 km, whichever comes first, meaning time elapsed is treated as an equally valid trigger as distance traveled.
• A 30,000 km check interval on a manual transaxle of this capacity is relatively frequent, consistent with a fluid level inspection and condition assessment rather than a mandatory fluid replacement at each interval.
