What does the dial on the Vauxhall Crossland dashboard do?

I recently purchased a Vauxhall Crossland and noticed a dial on the dashboard that I am unfamiliar with. Can you provide more details on its function and usage?

That dial is the trip odometer, which keeps track of the distance you have traveled since resetting it. You can use it to calculate your gas mileage and plan your next fill-up accordingly.

You can also use the dial to monitor your average fuel economy. Pay attention to it while driving to optimize your driving habits and maximize your gas mileage.

The dial can also be used to track your distance traveled on a single trip. Press the button on the end of the stalk to reset the trip odometer at the beginning of your journey.
