How can I increase the fuel efficiency of my Kia ProCeed?

I recently purchased a Kia ProCeed and I am looking for ways to improve its fuel efficiency. Are there any maintenance tips or driving techniques that can help me save on gas?

Maintain proper tire pressure. Under-inflated tires can decrease fuel efficiency.

Minimize idling. If you're going to be stopped for more than 30 seconds, it is more fuel efficient to turn off the engine.

Avoid aggressive driving. Rapid acceleration and braking can decrease fuel efficiency.
