How can I maintain my Nissan Juke's fuel efficiency?

I recently purchased a new Nissan Juke and I want to make sure I am maximizing its fuel efficiency. Are there any tips or tricks I should know?

One way to maintain fuel efficiency is to make sure your tires are properly inflated. This will not only improve gas mileage, but also help your tires last longer. Keep a tire pressure gauge in your car and check them regularly.

Another tip is to avoid unnecessary idling, especially in traffic. If you know you will be stopped for more than a minute, it is more efficient to turn off your engine and restart it when you are ready to move again.
