You don't need to pay for an owner'* manual. Go to pontiac.com and download one for free. Go to the owner'* section, select "visit the pontiac owner center", sign up for a free Yahoo account, back to the pontiac site where you fill in information about you and your car, and eventually you end up on a page where you can download an owner'* manual.
I did all of this in the last 10 minutes and was able to download a manual for your car. Its 17 Mb, or I would email it to you. Let me know if you can't figure this out and I can help you with it.
