Seating and safety restraints
recommends that all safety belt assemblies used in vehicles involved in a
collision be replaced. However, if the collision was minor and a qualified
technician finds that the belts do not show damage and continue to
operate properly, they do not need to be replaced. Safety belt assemblies
not in use during a collision should also be inspected and replaced if
either damage or improper operation is noted.
Failure to inspect and if necessary replace the safety belt
assembly under the above conditions could result in severe
personal injuries in the event of a collision.
Refer to Cleaning and maintaining the safety belts in the
Maintenance and care section.
SAFETY RESTRAINTS FOR CHILDREN
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.
