The start-stop system, standard on many modern Ford cars, was supposed to be the next step towards saving fuel and reducing emissions. In theory, it sounds sensible – the engine automatically turns off when the vehicle stops at a traffic light, in a traffic jam or during a stop, and then restarts when the clutch pedal is pressed or the brake is released. The problem is that the theory does not match the practice. More and more Ford owners openly admit: this system is simply irritating. And for good reason.

Why is the start-stop system so troublesome?

Although the idea of the start-stop system is to minimize fuel consumption and CO₂ emissions, the real savings are marginal – we are talking about a few percent on the scale of fuel consumption, which in everyday city driving does not translate into noticeable differences in the wallet. However, the side effects of the system are clearly noticeable:

• Delayed vehicle response – after stopping and automatically switching off the engine, the reaction to starting again may be delayed, especially in situations requiring quick action, e.g. joining traffic.
  
• Increased wear of the starter motor – frequent switching off and starting of the engine means greater load on the mechanical components.
  
• Cold start – in winter, the system can switch off the engine before it has time to warm up properly, which negatively affects driving comfort and the operation of the drive unit.
  
• No permanent shutdown possible – this is the biggest pain. Every time you start the vehicle, you have to manually turn the system off again, which is not only tiring, but simply impractical.
  

Temporarily deactivating the start-stop system in Ford

Ford offers users the option to turn off the start-stop system, but – crucially – only temporarily. In practice, it looks like this:

1. After starting the engine, you should press the physical button, marked with an icon of the letter "A" surrounded by an arrow (usually located in the center of the dashboard).
   
2. The system is switched off while driving – but only until the next engine start.
   
3. When the ignition is switched on again, the start-stop system automatically activates, regardless of previous settings.
   

For drivers who get into their cars every day and hit the road, this ritual becomes a frustrating addition. Many of them forget to deactivate it, and it is only when they suddenly turn off the engine at the first stop that they are reminded of the unwanted function.
