How can I improve gas mileage in my Nissan X-Trail?

I just bought a used 2017 Nissan X-Trail and I love it, but I've noticed that I'm not getting the best gas mileage. Is there something I can do to improve it?

One thing you can do is make sure your tires are properly inflated. Under-inflated tires can decrease gas mileage by up to 3%.

Another trick is to accelerate slowly and avoid sudden braking. This can improve gas mileage by up to 30%, depending on your driving habits.

If you're frequently driving in stop-and-go traffic, using cruise control can also help improve gas mileage.
