How do I unlock the gearbox of my Smart 450?
Years 1998-2007

Answer

The procedure to be carried out for the gearbox control unit of your Smart 450 to learn the position of the selector lever involves the following steps: make sure that the battery voltage is correct, then turn on the ignition; move the selector to the â € œNâ € position (move it to the right) and press the brake pedal until a gearshift adaptation sequence starts. The letter â € œNâ € will then appear and it will be possible to start the engine. If, on the other hand, the battery is completely discharged and the ignition does not turn on, you have to lift the cover of the gearbox and press the small button located between the gears, so as to unlock the gearbox.
