How can I improve my Kia Ceed's fuel economy?

I recently purchased a Kia Ceed and I've noticed that I'm not getting the best fuel economy. What are some steps I can take to improve it?

First, make sure your tires are properly inflated. Under-inflated tires can greatly impact fuel efficiency.

Next, try to avoid heavy acceleration and braking. This can use up more fuel than necessary.

Regular maintenance, such as getting an oil change and replacing air filters, can also help improve fuel economy.

Lastly, try to minimize your idling time. Turning off your engine when you're not moving can save a significant amount of fuel.
