This is fine Toyota normally recommends two options the 0W-20 or the 5W-30 so you should be fine with 5W-30.
As a tech for Toyota they/we will never test the type of oil you place in your car but keep in mind with the FRS you get free maintenance for 30k miles so talk to your dealership im sure they will help you. you may just need to pay a little money for different oil.
