What is the best way to increase fuel efficiency in a Ford EcoSport car?

I just bought a new Ford EcoSport and I noticed that it's not as fuel efficient as I expected. What are some tips and tricks to improve its fuel efficiency?

One important tip is to keep your tires properly inflated. Under-inflated tires can decrease fuel efficiency by up to 3%

Try to avoid aggressive driving and speeding. This can use up a lot of fuel, especially in a smaller car like the Ford EcoSport.
