Cadillac 2007 DTS Owner's Manual page 425

Notice: If you position the jack under the
rocker molding and attempt to raise the
vehicle, you could break the molding and/or
cause other damage to your vehicle. Always
position the jack so that when the jack head is
raised, it will fit firmly in the notch located
inboard from the rocker molding.
4. Turn the jack handle counterclockwise to
lower the jack lift head until the jack fits
under the vehicle.
5. Raise the jack until the metal flange fits firmly
into the channel of the jack head.
6. Put the spare tire near you.
7. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off
the ground for the spare tire to fit under
the vehicle.
8. Remove all wheel nuts and take off the
flat tire.
