The Smart Forfour Mk2 (W453) 2014-2021 is the five-door city car developed alongside the Renault Twingo, with its three-cylinder engine mounted in the rear. After a service this generation generally needs the oil service light reset to clear the maintenance counter, plus a service reminder reset through the dash display. A TPMS reset is handy after adjusting tyre pressures, a brake pad wear reset follows new pads, and the electric windows may require initialisation if the one-touch function stops after a 12V battery reset. Menu paths vary slightly across the W453’s production years and trims, so confirm your build. Choose the reset procedure you need from the list below to follow the matching steps for your Forfour.
