How do I improve the fuel efficiency of my Toyota Highlander?

I recently bought a Toyota Highlander and I've noticed that it uses a lot of gas. Is there any way to improve its fuel efficiency?

First, make sure your tires are properly inflated. Under-inflated tires can cause your car to use more gas than necessary.

Avoid aggressive driving and excessive idling. Both of these habits can significantly decrease your fuel efficiency.

Consider using cruise control on long highway drives. It can help maintain a consistent speed, which can improve fuel efficiency.
