Quite Mode on Nikon D5000?

Can you give me a detailed way to get to quiet mode on the NIkon D5000? I'm new to this stuff.

Whenever I have a question/problem such as yours, I read the user's guide
(aka "the manual").
It is amazing just how much I always learn from that.

If that doesn't help (or if I'm interested in a product I don't own), I check the manufacturer's website.
They have descriptions and specs for their gadgets, often have user forums, and the decent manufacturers all let you download the manuals in electronic form (so losing the book is no longer a problem).

99% of the time that does the trick.
