Seating and Safety Restraints
Important child restraint precautions
WARNING: Always make sure your child is secured properly in
a device that is appropriate for their height, age and weight.
Child safety restraints must be purchased separately from the vehicle.
Failure to follow these instructions and guidelines may result in an
increased risk of serious injury or death to your child.
WARNING: All children are shaped differently. The
Recommendations for Safety Restraints are based on probable
child height, age and weight thresholds from NHTSA and other safety
organizations or are the minimum requirements of law. Ford
recommends checking with a NHTSA Certified Child Passenger Safety
Technician (CPST) and your pediatrician to make sure your child seat
is appropriate for your child, and is compatible with and properly
installed in the vehicle. To locate a child seat fitting station and CPST
contact the NHTSA toll free at 1-888-327-4236 or on the internet at
http://www.nhtsa.dot.gov. Failure to properly restrain children in safety
seats made especially for their height, age, and weight may result in an
increased risk of serious injury or death to your child.
