How can I maintain my Kia Ceed's fuel efficiency?

I just bought a Kia Ceed and I'm wondering what steps I can take to ensure that it maintains its fuel efficiency. Are there any specific maintenance tasks or driving habits I should be aware of?

Regularly check and change your engine oil according to your owner's manual. This will help your engine run smoothly and efficiently.

Ensure that your tires are properly inflated. Under-inflated tires can decrease fuel efficiency.

Practicing smooth and steady acceleration and braking can improve your fuel efficiency. Avoid rapid acceleration and hard braking.

Use cruise control on the highway to maintain a consistent speed, which can improve your fuel efficiency.
