Okay, now I understand the difference between the perimeter alarm and the PATS. So, if I understand completely, the 2005 has no anti-theft system other than an audible alarm? Beautiful. Hope my insurance company doesn't find out about this or they might want their 20% back for the passive anti-theft system discount. Even worse, I hope the criminals don't find out about this because apparently an '05 Hybrid will be as easy to steal as cars were 20 years ago.....
