The Chilton's service manual for the 2002-2007 Saturn Vue, Part number 62390 can be purchased at O'Reilly Auto Parts for $19.95 plus tax, they may have to order it for you. It took me two business days to receive mine. Haynes also has a manual for the same years for the Vue. Auto Zone may be able to get it also.
