How to optimize fuel efficiency in a Nissan X-Trail?

I recently purchased a Nissan X-Trail and I am wondering what tips and tricks I can implement to improve its fuel efficiency. I have been using it for daily commute and the gas mileage is not as great as I had expected. Any suggestions?

Firstly, make sure to keep up with regular maintenance such as oil changes and tire rotations. This can greatly impact your fuel efficiency.

Another tip is to avoid unnecessary idling and aggressive driving. These habits can significantly decrease your gas mileage.
