How do I increase the fuel economy on my Ford S-Max?

I have noticed that my Ford S-Max is not getting as good gas mileage as it used to. Can you provide any tips on how to increase the fuel efficiency?

One way to increase your Ford S-Max's fuel economy is to make sure your tires are properly inflated. Under-inflated tires can decrease gas mileage.

Another helpful tip is to avoid rapid acceleration and heavy braking. This can use up more fuel than necessary.
