The book doesn't really let you know what you're supposed to do since it's not really designed for self teaching, but basically you're just supposed to ignore all of the kanji they list in the vocabulary section starting with Chapter 3. You can try and learn it if you want, but it's not the way the book works. If you're on chapter 3, for example, you're supposed to flip to the chapter 3 section of the back of the book where they begin to teach you more basic kanji along with different radicals. As you progress through the book, you'll start to learn what some of the kanji is in the vocabulary lists. That's why they always provide you with hiragana when applicable for the vocab.
