GMC 2007 Savana - Manual (Page 368)

{ 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 ratchet
clockwise. Make sure the UP mark faces you.
Raise the vehicle far enough off the ground
so there is enough room for the spare
tire to fit.
