Cadillac 1996 Eldorado Owner's Manual page 255

Secure the tire with the stud cap that was used to hold
the compact spare in place. Store the cover as far
forward as possible.
Storing a jack, a tire or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
