The Hyundai Bayon is a compact entry-level crossover named after the French city, offering tidy dimensions and modern cabin tech. Its service-reminder electronics keep track of maintenance, and the system needs a manual reset once the work is done, or the wrench symbol stays lit on the cluster. Bayon owners typically handle an oil service reset, clear the maintenance reminder, run a TPMS reset to re-learn tyre pressures and reinitialise the electric windows following a battery disconnect. Because the menu layout can change between model years, we keep the guides grouped by generation for accuracy. Select your Bayon’s generation below to open the reset steps that apply to your car.
