Chevrolet 1997 Cavalier Owner's Manual page 234

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.
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 your vehicle.

NOTICE:
~~ ~~~ ~
Do not jack or lift the vehicle using the oil pan.
Pans could crack and begin to leak fluid.
4. Raise the vehicle by rotating the wheel wrench
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the spare tire
to fit.
5 . Remove all of the wheel nuts.
