How to reset the gearbox of the Smart 451?

Model: Smart Smart 451 - Years 2007-2015
Part: Warning light – error code

When the flashing letter N appears on the instrument panel display of the Smart 451, it means that the gear change is faulty. To be able to resolve this anomaly temporarily, it is possible to engage gear with the engine off. Subsequently, with the gear engaged and with the ignition key in position two, the car must be pushed so that it can start. Once the clutch is released during the push operation, the car will start. However, you must go to the workshop promptly to solve the problem and avoid worse damage.
