I agree with olduser 1 . While the car is under manufacturers warranty get it serviced by Honda.
While it may be possible to keep the warranty valid if the car is serviced by an independent,non Honda ,garage they would normally have to be a fully recognised,professionally qualified,garage business. With professional paperwork. Probably best to check first with Honda Portugal if that garage would be acceptable - dont ask your local Honda dealership , they will want to say no. But doing it at home would invalidate your warranty.
But note that hybrids have very high voltage batteries and battery leads. They can be dangerous if you are not sure what you are doing. Not all professional garages are qualified to work on them either. Also the car requires a particular type of engine oil. You can buy it easily enough,but its quite expensive . An independent garage may not have it in stock and may use something else.
