What can I do to improve my Ford S-Max's fuel efficiency?

I just got my Ford S-Max and while I love the drive and features, I am concerned about its fuel efficiency. Are there any tips or tricks I can use to improve my car's gas mileage?

One way to improve fuel efficiency is to maintain proper tire pressure. Under-inflated tires can cause your car to use more gas.

Another tip is to avoid idling for too long. If you're waiting in your car for more than a minute, turn off the engine to save gas.

You can also try using cruise control on the highway, as it can help regulate your speed and save gas.
