Chevrolet 1998 Corvette Owner's Manual page 45

A booster seat (F, G) is designed for children who
are about 40 to 60 lbs. (1 8 to 27 kg) and about
four to eight years of age. It's designed to improve
the fit of the vehicle's safety belt system. Booster
seats with shields use lap-only belts; however,
booster seats without shields use lap-shoulder
belts. Booster seats can also help a child to see
out the window.
