The start-stop system was supposed to help drivers save fuel and protect the environment. In practice, however, it has become a source of irritation, especially for Fiat owners. Constant engine shutting off and on during short stops, delayed response to accelerator pedal pressure, and the need to manually deactivate the system each time are just some of the reasons many drivers want to simply get rid of it.

In this article, we'll show you how to temporarily and permanently disable the start-stop system in your Fiat. No moralizing, no ecological sermons – just the facts.

Why does the start-stop system in a Fiat interfere with everyday driving?

While the idea of automatically shutting off the engine when stationary may seem logical, the reality on the road is different. In Fiats, the start-stop system can deactivate the engine in moments that are completely impractical – for example, when slowly maneuvering in a parking lot, in a traffic jam, or approaching a roundabout.

Most common driver complaints:

• Delay in restarting the engine, which causes nervousness when pulling away from traffic lights.
  
• Additional wear and tear on the battery and starter, especially in winter.
  
• The need to turn off the system each time the engine is started – because the system is always activated by default.
  

Fiat—like many other manufacturers—doesn't allow users to permanently disable this system from the vehicle's menu. As a result, drivers are forced to press the same button every day. Absurd? A bit like that.

How do I turn off the start-stop system temporarily while driving?

Fiats equipped with a start-stop system have a dedicated button, usually with the letter "A" surrounded by an arrow. Pressing it deactivates the system – but only until the end of the current driving sessionAfter turning the engine off and on again, the system will be active again.

This is a temporary solution. For many drivers, it's simply insufficient. It's hard to find the daily, routine shutdown of the system convenient – especially when everything else in the car can be set once and for all these days.

• Fiat Tipo (2016–2024) – many users complain about the engine turning off too early and restarting slowly.
  
• Fiat 500X (2015–2024) – the system can be overzealous and react at inappropriate moments.

• Fiat 500 (2008–2024) – a small city car that loses its smooth driving characteristics due to the start-stop system.
