Cadillac 2008 DTS - Manual (Page 375)

{ 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.
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.
5. Turn the jack handle counterclockwise to lower the
jack lift head until the jack fits under the vehicle.
6. Raise the jack until the metal flange fits firmly
into the channel of the jack head.
7. Put the spare tire near you.
