The Mazda CX-3 is a compact crossover that borrows the brand’s mature SkyActiv styling and engaging drive in a city-friendly size. Its service-reminder electronics track mileage and time, and they expect a manual reset once maintenance is finished, otherwise the wrench icon stays on the display. CX-3 owners typically reset the oil service indicator, clear the maintenance light, perform a TPMS reset to re-learn tyre pressures and reinitialise the power windows after a battery disconnect. Since the cluster menus changed between CX-3 generations, we keep each generation’s guides apart so the steps match your car. Pick your CX-3’s generation below to open the reset procedures that apply to your version.
