Pontiac 2003 Bonneville Owner's Manual page 37

Every time infants and young children ride in vehicles,
they should have the protection provided by appropriate
restraints. Young children should not use the vehicle's
adult safety belts alone, unless there is no other choice.
Instead, they need to use a child restraint.
People should never hold a bab n their arms
while riding in a vehicle. A baby doesn't weigh
much
--
until a crash. During a crash a baby
~
will become so heavy it is not possible to hold
~
it. For example,
in a crash at only 25 mph
~
(40 km/h), a 12-lb. (5.5 kg) baby will suddenly
~
become a 240-lb. (110 kg) force on a person's
arms. A baby should be secured in an
appropriate restraint.
