What is the best way to increase fuel efficiency in the Ford S-Max?

I recently purchased a Ford S-Max and I've noticed that it's not as fuel efficient as I was expecting. Does anyone have any tips or tricks for maximizing fuel efficiency in this car?

Regularly maintaining your car, including checking your tire pressure and getting tune-ups, can greatly improve fuel efficiency.

Avoiding aggressive driving and using cruise control on the highway can also help save gas in the long run.

Making sure your car is not carrying unnecessary weight and using the correct grade of gasoline can also make a difference.
