How can I improve fuel efficiency in my Nissan X-Trail?

I've noticed that my Nissan X-Trail's fuel consumption has been higher than expected. Is there anything I can do to improve its fuel efficiency?

Properly maintaining your Nissan X-Trail can significantly improve its fuel efficiency. Make sure to regularly check and replace air filters, spark plugs, and engine oil.

Utilizing cruise control on long trips can also help improve fuel efficiency as it maintains a consistent speed and reduces unnecessary acceleration.
