Pontiac 1998 Sunfire Owner's Manual page 58

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.
