Why is the fuel efficiency of the Kia ProCeed lower than expected?

I recently purchased the Kia ProCeed and was disappointed to find that its fuel efficiency is not as good as the advertised numbers. I've been driving carefully and keeping up with maintenance, so what could be causing this issue?

It's possible that you're not using the most efficient driving techniques. Try accelerating and braking smoothly, and avoid idling for extended periods.

Do you typically drive in heavy traffic or on hilly terrain? These conditions can significantly impact fuel efficiency.

Have you checked your tire pressure? Low tire pressure can also affect fuel efficiency.
