The Scuderia currently sit second in the Constructors’ Championship, 39 points shy of Mercedes, although Raikkonen’s team mate Sebastian Vettel leads the Drivers’ Championship.
Vettel claimed his latest victory last time out at the Hungarian Grand Prix while Raikkonen came home a close second, but the Finn feels the title race will continue to surprise when the campaign resumes after the summer break.
The Belgian Grand Prix is next up on the calendar at the end of August and Raikkonen has stressed the importance of improving on a strong first half to the season.
Raikkonen said: "Now we take the holiday and see what happens in Spa, but if you look at it now, it's not going to be as easy for us there as it was in Hungary. We obviously try to improve and hope to be quick there too."
