What Does the ECO Button Do on the Vauxhall Astra?

I recently bought a Vauxhall Astra and noticed there is an ECO button. What does this button do and should I be using it?

The ECO button stands for Economic Mode and it adjusts various systems in the car to improve fuel efficiency. It is recommended to use it if you want to save on fuel costs.

The ECO button can also impact the car's performance by decreasing power and acceleration. If you're driving on a hilly or mountainous terrain, it might be better to turn off the ECO mode for a smoother driving experience.

In general, using the ECO button can help reduce emissions and contribute to a more sustainable driving experience.
