The Toyota Mirai is one of the few mainstream hydrogen fuel-cell cars on the road, drawing its power from a fuel-cell stack and an electric motor rather than a combustion engine. Because there is no engine and no engine oil, its servicing centres on its electronic and electrical systems instead. After a workshop visit you may still need to clear the maintenance reminder, complete a TPMS reset when tyre pressures change, and reinitialise systems after a 12V battery reset or replacement. The electronic parking brake also has a service mode for brake work, and several electronic control modules expect a relearn afterwards. The exact menu path and button sequence differ across the model run, so choose the correct Mirai generation below to follow the matching procedure.
