How do I release the parking brake as my engine is dead and my battery is dead? on 2000 Cadillac Seville STS

I need to tow the car but I am stuck. Is there a manual release or is my only option to cut the cable?

Look in owners manual for overide or use jumper cables/box on battery long enough to release brake!

I have the manual on my 2000 Cadillac and it says to release the parking brake, just put it in gear. I was at the Library and had my parking brake on and couldn't find any release. Then I read the manual and it worked.
Good job!! Thanks for the heads up!!!!
