The Smart Forfour stretches the city-car formula to four doors and four seats while keeping its rear-engined layout and nimble turning circle. Even this small car relies on electronic service monitoring that has to be reset once maintenance is done. The usual tasks are an oil service light reset to clear the maintenance light, a service reminder reset after scheduled work, and a TPMS reset where the system is fitted. Because the original Mitsubishi-based Forfour and the later Renault-Twingo-based car use different dashboards, the steps aren’t shared. Choose your Forfour generation from the list below to open the matching service reset instructions.
