Seats and Restraints 79
Infants and Young
Children
Everyone in a vehicle needsprotection! This includes infants andall other children. Neither thedistance traveled nor the age andsize of the traveler changes theneed, for everyone, to use safetyrestraints. In fact, the law in everystate in the United States and inevery Canadian province sayschildren up to some age must berestrained while in a vehicle.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor,
but it cannot do this if it is
wrapped around a child’sneck.
If the shoulder belt is locked and
tightened around a child’sneck,
the only way to loosen the belt is
to cut it.
Never leave children unattended
in a vehicle and never allow
children to play with the safety
belts.
Every time infants and youngchildren ride in vehicles, they shouldhave the protection provided byappropriate child restraints. Neither
the vehicle's safety belt system norits airbag system is designedfor them.
Children who are not restrainedproperly can strike other people,or can be thrown out of the vehicle.
{Warning
Never hold an infant or a child
while riding in a vehicle. Due to
crash forces, an infant or a child
will become so heavy it is not
possible to hold it during a crash.
For example, in a crash at only
40 km/h (25 mph), a 5.5 kg (12 lb)
infant will suddenly become a
11 0 k g ( 2 4 0 l b ) f o r c e o n a p e r s o n ' s
arms. An infant or child should be
secured in an appropriate
restraint.

the instructions that come with thechild restraint say that the top tethermust be attached.
According to accident statistics,children and infants are safer whenproperly restrained in a childrestraint system or infant restraintsystem secured in a rear seatingposition. SeeWhere to Put theRestraint083for additionalinformation.
Securing a Child Restraint
Designed for the LATCH
System
{Warning
If a LATCH-type child restraint is
not attached to anchors, the child
restraint will not be able to protect
the child correctly. In a crash, the
child could be seriously injured or
killed. Install a LATCH-type child
restraint properly using the
anchors, or use the vehicle's
safety belts to secure the
restraint, following the instructions
(Continued)
Warning (Continued)
that came with the child restraint
and the instructions in this
manual.
{Warning
To r e d u c e t h e r i s k o f s e r i o u s o r
fatal injuries during a crash, do
not attach more than one child
restraint to a single anchor.
Attaching more than one child
restraint to a single anchor could
cause the anchor or attachment
to come loose or even break
during a crash. A child or others
could be injured.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck. The
(Continued)
Warning (Continued)
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor,
but it cannot do this if it is
wrapped around a child’sneck.
If the shoulder belt is locked and
tightened around a child’sneck,
the only way to loosen the belt is
to cut it.
Buckle any unused safety belts
behind the child restraint so
children cannot reach them. Pull
the shoulder belt all the way out
of the retractor to set the lock,
and tighten the belt behind the
child restraint after the child
restraint has been installed.
