It's normal. Turbo engines use a bit more oil, so it's normal to pour some in once in a while.
I just looked at the first oil change recommendation for the new 2.0L TwinPower Turbo inline 4-cylinder engine (N20) which is at 15,000 miles or 24 months whichever comes first. Now THAT would worry me. I can't see anyone driving more than 5,000 miles on a brand new car without getting its first oil change. Have you had the 1st oil change yet? You're almost at 5,000 miles.
