The Hyundai Bayon Mk1 (BC3) (2021–Present) is Hyundai’s compact, distinctively styled crossover for Europe, sharing its platform with the i20 and offered with frugal petrol and 48V mild-hybrid powertrains. After a service, several electronic systems expect resetting. The oil service reset clears the interval counter from the digital cluster once fresh oil and a filter are in; a major service adds the maintenance reminder reset. A TPMS reset relearns tyre pressures after a rotation, new brake pads need the wear warning cleared, and a steering angle calibration follows alignment work. A replacement 12V battery may need registering, particularly on mild-hybrid examples. Open the exact reset for your Bayon from the procedure list shown directly below.
