Cadillac 1999 Eldorado Owner's Manual page 239

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.
3. Attatch the wheel wrench to the jack. Turn the wheel
wrench counterclockwise to lower the jack lift head
until the jack fits under the car.
4. Position the jack under the vehicle and raise the jack
lift head until it fits firmly into the notch in the
vehicle's frame nearest the flat tire.
Put the compact spare tire near you.
5. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground so that the flat tire can be removed and the
spare tire will fit on the wheel mounting surface.
6. Remove all wheel nuts and take off the flat tire.
