If you find that your safety seat moves or your vehicle seat belt slips or
becomes loose, make sure you have followed steps 1-15 correctly, or see
section 4, "Selecting a Suitable Location for the Safety Seat" (page 13).
DO NOT USE THIS SEATING LOCATION IF THE SEAT BELT DOES
NOT HOLD THE SAFETY SEAT TIGHTLY.
9. Using the Safety Seat in an Airplane
This safety seat may be installed in an airplane
the same way that it is installed in an automobile.
Since airlines have some restrictions about the use
of safety seats, notify the airline ahead of time
that you intend to bring the seat on board.
Again, for the safety of your child, use the safety seat in forward-facing
aircraft seats only. Follow the flight attendant's instructions about safety
seat placement. Follow the installation instructions as previously described.
Always be sure that the airplane seat belt is adjusted so that it tightly
holds the safety seat in place at all times.
