Hi and thanks for using 2CarPros.
The belt is held on by an automatic tensioner located toward the top of the engine. Here is a link that shows how one gets replaced. Additionally, I have attached a picture specific to your vehicle below.

Let me know if this helps or if you have other questions.
Take care,
Joe
