What is the best way to improve the fuel efficiency of a Ford S-Max?

I recently purchased a Ford S-Max and I am looking for ways to improve its fuel efficiency. Are there any modifications I can make or driving habits I should adopt?

One of the best ways to improve fuel efficiency is to keep your tires properly inflated. This will reduce rolling resistance and improve your car's fuel consumption.

You can also try changing your driving habits. Avoiding rapid acceleration and braking can greatly improve fuel efficiency.

Consider using cruise control on the highway as this can help maintain a constant speed and save on fuel.
