"I am just wanting to maximise this opportunity, enjoy the ride, enjoy being a Ferrari driver and I will make sure I realise that every race, I am a Ferrari driver," he said.
"I have to enjoy this experience because this has been a dream for me since I was 10 years old.
"The rest, keep working hard, keep applying my working method and ensure we get to the top as soon as possible."
The current season is the 26-year-old's seventh in Formula 1 with time previously spent at Toro Rosso, Renault and McLaren although Sainz found it difficult to vocalise the differences between Ferrari and his former employers.
He added: "It is different. It is a very special place to be.
"When I arrived in January and getting the experience of going into the factory for the first time, going to the Fiorano test and to meet the Tifosi whilst being a Ferrari driver is something I had never experienced before and something really special in any Formula 1 driver's career.
