How to increase the fuel efficiency in my Kia Ceed?

I recently bought a Kia Ceed and I've noticed that I'm spending a lot on fuel. What are some ways I can increase the fuel efficiency in my car?

Try to avoid sudden acceleration and braking, as this can waste fuel. Instead, drive at a steady pace and use cruise control when possible.

Make sure your tires are properly inflated, as under-inflated tires can decrease your gas mileage. Check your tire pressure regularly and always before long drives.

First of all, make sure you are following proper maintenance schedule and getting regular tune-ups. This can greatly improve your fuel efficiency.
