Securing a Child Restraint Designed for
the LATCH System
{CAUTION:
If a LATCH-type child restraint is not
attached to anchors, the restraint will not
be able to protect the child correctly. In a
crash, the child could be seriously injured
or killed. Make sure that a LATCH-type
child restraint is properly installed using
the anchors, or use the vehicle’s safety
belts to secure the restraint, following the
instructions that came with that restraint,
and also the instructions in this manual.
{CAUTION:
Each top tether anchor, except the center
top tether anchor in an extended cab
model, and lower anchors in the vehicle
are designed to hold only one child
restraint. 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 if this happens. To
help prevent injury to people and damage
to your vehicle, attach only one child
restraint per anchor.
64

{CAUTION:
Children can be seriously injured or
strangled if a shoulder belt is wrapped
around their neck and the safety belt
continues to tighten. Secure 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, if your vehicle
has one, after the child restraint has been
installed. Be sure to follow the
instructions of the child restraint
manufacturer.
Notice:Contact between the child restraint or
the LATCH attachment parts and the vehicle’s
safety belt assembly may cause damage to
these parts. Make sure when securing unused
safety belts behind the child restraint that
there is no contact between the child restraint
or the LATCH attachment parts and the
vehicle’s safety belt assembly.Folding an empty rear seat with the safety
belts secured may cause damage to the safety
belt or the seat. When removing the child
restraint, always remember to return the safety
belts to their normal, stowed position before
folding the rear seat.
