Oldsmobile 1998 Intrigue Owner's Manual page 47

A forward-facing child restraint (C-E) positions a
child upright to face forward in the vehicle. These
forward-facing restraints are designed to help protect
children who are from 20 to 40 lbs. (9 to 18 kg) and
about 26 to 40 inches (66 to 102 cm) in height, or up
to around four years of age. One type, a convertible
restraint, is designed to be used either as a rear-facing
infant seat or a forward-facing child seat.
