What does the Gear Shift Indicator do in a Vauxhall Crossland?

I just bought a Vauxhall Crossland and I noticed a gear shift indicator on the dashboard. What purpose does it serve and how can I use it effectively while driving?

The Gear Shift Indicator is designed to help optimize your fuel consumption while driving. It displays the most fuel efficient gear for the current speed and driving conditions. To use it effectively, try to keep the indicator in the green zone by shifting to the recommended gear.

The Gear Shift Indicator can also improve your driving habits. By paying attention to it, you can learn when to shift gears in different driving situations. This can lead to smoother and more fuel efficient driving overall.
