Chevrolet MONTE CARLO 1998 Manual page 53

To
remove the child restraint, just unbuckle the vehicle's
safety belt and let it go back all the way. The safety belt
will
move
freely again and be ready to work for an adult
or larger child passenger.
Securing a Child Restraint in the Center
Rear Seat Position
You'll be using the lap belt. Be sure to follow the
instructions that came with the child restraint. Secure
the child in the child restraint when and as the
instructions say.
A child in a child restraint in the center front seat
can be badly injured by the right front passenger
air bag if it inflates. Never secure a child restraint
in the center front seat. It's always better to
secure a child restraint in the rear seat. You may,
however, secure a forward-facing child restraint
in the right front passenger seat, but only with
the seat moved all the way back.
See the earlier part about the top strap if the child
restraint has one.
