How do I get the best fuel efficiency in my Nissan X-Trail?

I've been noticing that I'm not getting as good of fuel efficiency as I expected in my Nissan X-Trail. Any tips on how to improve it?

Regularly check your tire pressure to ensure it's at the optimal level for your vehicle. This can greatly affect fuel efficiency.

Avoid aggressive driving and using your air conditioning all the time. These can both have a negative impact on fuel efficiency.
