Let's see how to deactivate the start & stop on the Smart 453 (and also on the Renault Twingo). The temporary solution is the one shown in the video, which is to press the button located at the bottom of the dashboard, to the left of the steering wheel, with the red light on. However, it must be pressed every time the car is started, and the deactivation only applies to the current driving cycle.

If you want to permanently eliminate it, there are specific emulators or bypasses that connect to the battery sensor or the control unit, such as the "Start Stop Memory module" that can be found on Amazon in one of its many versions with the code B0CMCR53BT at a price of 24.98 euros, delivery in one day with no delivery costs for Prime customers.
