How do I increase fuel efficiency in the Kia Stonic?

I recently purchased a Kia Stonic and I have noticed that I am not getting the fuel efficiency that was advertised. Is there anything I can do to improve my fuel efficiency?

One tip for increasing fuel efficiency is to make sure your tires are properly inflated. Under-inflated tires can decrease gas mileage. Regularly checking and inflating your tires to the recommended PSI can make a difference.

Another way to improve fuel efficiency is to avoid excessive idling. If you are parked and waiting for someone, it is better to turn off your car rather than letting it idle. Idling can use up unnecessary fuel.

A third tip is to drive smoothly and avoid aggressive acceleration and braking. This not only reduces fuel consumption but also prolongs the life of your car's components.
