How do I improve the fuel efficiency in my Ford S-Max?

I have noticed that my Ford S-Max seems to be using more fuel than usual lately. Is there anything I can do to improve its fuel efficiency?

One way to improve fuel efficiency is to maintain your car's tires at the recommended pressure. This can increase gas mileage by up to 3%.

Another tip is to avoid idling for long periods of time. Shut off your engine if you're going to be parked for more than a minute.

Cruise control can also help improve fuel efficiency, especially on long highway drives. Just don't use it in heavy traffic or on hilly roads.
