最初の15分は駐車代が無料です。

最初の例文は we を主語にしているので自分たち主観の言い方で、２つ目の例文は parking is... と始まっているので客観的な事実を述べているニュアンスです。

They won't charge you if you leave in 15 minutes.

(15分以内に出れば、駐車台は無料だよ）
2.They won't charge you if you leave within 15 minutes.
（１５分以内に出れば、（彼らは）駐車代は請求されないよ）
「駐車代/the parking fee」または、
「彼ら・請求する人たちをさす/they」を
それぞれ主語にした場合の違った言い方です。意味はほとんど
同じでも主語が変わるだけで、ニュアンスが多少変わってきますよね。
15分以内とは、in 15 minutes/within 15 minutesと２通りあります。
When you use "if," it means that a sentence is conditional. In this case the condition is that parking is free IF you leave within 15 minutes. I hope that this helps :)
If you leave within 15 minutes, parking is free.
（15分以内に出庫すると、駐車料金がかからない）
"if"を使うと、条件文になります。
この場合その条件とは「15分以内に出庫する」ことです。
お役に立てれば幸いです :)
