How can I improve the fuel efficiency on my Nissan Qashqai?

I've noticed that my Nissan Qashqai is not as fuel efficient as I would like. What steps can I take to improve its fuel efficiency?

Make sure to regularly service your car and replace any worn out parts. This can greatly improve your fuel efficiency.

Avoid excessive idling and accelerate slowly to conserve fuel.

Check your tire pressure regularly and make sure they are properly inflated. Underinflated tires can decrease fuel efficiency.
