How to increase the fuel efficiency of my Kia Niro?

I recently purchased a Kia Niro and noticed that its fuel efficiency is not as good as advertised. What are some tips to improve its fuel efficiency?

First, make sure to keep your tires properly inflated. Underinflated tires can decrease fuel efficiency by up to 3%. Also, avoid using the air conditioning unless necessary, as it can decrease fuel efficiency by up to 25%.

Another tip is to avoid idling for long periods of time. If you're stuck in traffic, turn off the engine. This will save you fuel and reduce emissions. Additionally, try to accelerate and brake smoothly, as aggressive driving can greatly decrease fuel efficiency.

Regular maintenance is also important for maintaining fuel efficiency. Make sure to change your oil and air filters according to the manufacturer's recommendations. A clogged air filter can decrease fuel efficiency by up to 10%.
