Wasn't asked to sign but it's probably a way to get buyers to understand that this car IS different.
Had a broken tail light and had to be replaced -- could
NOT buy the standard Toyota taillight for a 2006 Highlander -- had to buy a 2006 Hybrid taillight as the electrical system is DIFFERENT!
So be very careful what you install or you will probably VOID your warranty!
