How can I make my Nissan Juke more fuel efficient?

I recently bought a Nissan Juke and I love it, but I'm a little worried about the gas mileage. Are there any tips or tricks I can use to improve its fuel efficiency?

One way to improve fuel efficiency is to make sure your tires are properly inflated. Under-inflated tires can decrease gas mileage by up to 20%. So be sure to check your tire pressure regularly.
