Seating and safety restraints
Important child restraint precautions
You are required by law to use safety restraints for
children in the U.S. and Canada. If small children
ride in your vehicle (generally children who are four
years old or younger and who weigh 18 kg [40 lbs]
or less), you must put them in safety seats made
especially for children. Check your local and state or
provincial laws for specific requirements regarding
the safety of children in your vehicle.
Never let a passenger hold a child on his or
her lap while the vehicle is moving. The
passenger cannot protect the child from injury in a
collision.
Always follow the instructions and warnings that
come with any infant or child restraint you might
use.
When possible, always place children under age 12
in the rear seat of your vehicle. Accident statistics
suggest that children are safer when properly
restrained in the rear seating positions than in the
front seating position.
Children and safety belts
If the child is the proper size, restrain the child in a
safety seat.
Children who are too large for child safety seats (as
specified by your child safety seat manufacturer)
should always wear safety belts.
Follow all the important safety restraint and air bag
precautions that apply to adult passengers in your
vehicle.
If the shoulder belt portion of a combination lap and
shoulder belt can be positioned so it does not cross
or rest in front of the child's face or neck, the child
should wear the lap and shoulder belt. Moving the
child closer to the center of the vehicle may help
provide a good shoulder belt fit.
