Where is the in cabin air filter located in the xterra's? How do you change them?

Not that this is the right section for this question, but I'll answer it:
Click here (http://www.xterraparts.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=Xterra&Product_Code=B7200-00001)
There's a link for the instructions there, right above the corrections for the Xterra.
