Car check help before going long journey (new car owner)?

Hi. I had just bought a new Ford Fiesta. This is my very first car that I owned. Previously, I would be driving a car that would be checked by my brother every time we travel on a long distance journey. Now I would be maintaining the car myself. I would like to find out what do I need to check and how could I do those checks on my car before starting my journey. The only thing I'm aware of checking are tire pressure.

Well how long have you owned it and how many miles are on it. But check oil level every time you fill up with gas. Check air pressure in the mornings when cold for accurate reading. When the tires get hot air in them expand and can give you false readings. Recheck the air in the spare tire make sure that's o.k
