The fourth-generation Kia Rio Mk4 (YB) (2017–2023) brought crisper styling and a roomier cabin to Kia’s supermini, sharing its platform with the Hyundai i20. After routine work, several electronic counters expect to be cleared. The oil service reset is the everyday job, done from the instrument cluster’s trip menu once the oil and filter are renewed. A major service usually wants the broader maintenance reminder reset, and a TPMS reset relearns tyre pressures after a rotation. Fit new brake pads and the wear warning needs clearing; disconnect or replace the 12V battery and stored settings, including powered-window auto function, may need re-initialising. Choose the reset routine that matches your Rio from the list of procedures shown directly below.
