Chevrolet 2007 HH7 Owner's Manual page 361

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.
3. Raise the vehicle by turning the jack handle
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.
