How to improve the fuel efficiency in my Kia Niro?

I recently purchased a Kia Niro and I'm looking for ways to improve its fuel efficiency. Are there any specific tips or tricks that I can follow?

Regularly check and replace your air filter. A clean filter can improve your fuel efficiency by up to 7%.

Inflate your tires to the recommended pressure. Under-inflated tires can decrease fuel efficiency by 0.2% for every 1 psi.

Avoid excessive idling. Turn off the engine if you're going to be stopped for more than 30 seconds.
