What is the best way to improve fuel efficiency in a Kia ProCeed?

I am looking for ways to increase my Kia ProCeed's fuel efficiency. Can anyone provide some tips or recommendations?

Regularly maintain your car's engine to ensure it is running efficiently. This can include changing the oil, air filter, and spark plugs as recommended by the manufacturer.

Inflate your tires to the recommended pressure. This can help reduce fuel consumption and improve handling.

Avoid idling for extended periods of time and try to combine errands to reduce the number of trips you make in your car.
