How to replace the ECO button on a Smart 451

Model: Smart Smart 451 - Years 2007-2015
Part: Push button

In this video, we will see how to replace the ECO button on a Smart 451: it is a mechanically simple operation, but it requires attention. First, let's get a button that we can find on Ali Express with the code 1005005240245387 at the price of 4.10 euros, with free delivery. Disconnect the battery; turn the ring that locks the gear lever counterclockwise to release the clip, and then pull the gear lever upwards to remove it. Now we need to remove the central console that houses the ECO button, inserting a spatula between the console and the trim, and exerting slight pressure to release the clips. Once the console is removed, we will see the electrical connectors on the back of the button: disconnect them. The button is held by small screws that we will unscrew. Install the new button and reconnect the connector. Repeat all the steps in reverse order to put the console and gear lever back in place.
