I belive this will help, there's a thread on how to change the blades. They talk about going to the dealer and have the blades put in. Also, what year Prius you got? Mine is a 2006 Prius. 2004 -2007 and up to 2009 have the same configurations. 1997-2001 was the 1st generation Prius, 2000-2003 have some other upgrades. 2009 version is rumored to get 80-113 MPGHow to change Prius Wiper Blade?
