Pontiac 2004 GTO - Manual (Page 264)

{ CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get
under a vehicle when it is supported only by
a jack.
{ CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to fit the
jack lift head into the proper location before
raising the vehicle.
4. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the compact
spare tire to fit underneath the wheel well.
The jack handle must be unfolded to a right angle
before it is used.
5. Remove all of the wheel nuts.
6. Remove the flat tire.
