stall a rearward facing child safety seat on
the front passenger seat in exceptional c ir­
cumstances.
- A tight tether strap on a rearward-facing
child restraint attached to the front passen­
ger seat can put too much pressure on the
we ight-mat in the seat and register a heavi­
er we ight in the Advanced Airbag System.
The heavier we ight registered can make the
system work as though an adult were on the
seat and deploy the Advanced Airbag when
it m ust be suppressed c ausing serious or
even fatal injury to the child.

LATCH system (Lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
To provide a simpler and more practicable way to
attach the child restraint on the vehicle seat,
F ederal regulations require special lower ancho­
rages in vehicles and devices on new child re­
straints to attach to the vehicle anchorages.
In the United States, the combination of the
tether anchorages and the lower anchorages is
now generally called the LA TCH system for
" L ower Anchorages and Tethers for Children". In
Canada, the terms "top tether" with "lower uni­
versal anchorages" (or "lower universal anchor ­
age bars") are used to describe the system.
In other countries the term "ISOFIX" is used to
describe the lower anchorages .
F orward-facing child restraints manufactured af­
ter September 1, 1999, are required by U.S. fed­
eral regulations to comply with new child head
movement performance requirements. These
new performance requirements make a tether
necessary on most new child seats.
Installing a child restraint that requires a top
tether without one can seriously impair the per­
formance of the child restraint and its ability to protect the child in a collision . Installing a child
restraint that requires a top tether without the
top tether may be a violation of state law.
Child restraint manufacturers offer LATCH lower
anchorages on their child seats with hook-on or push-on connectors attached to adjustable
straps.
In addition to the LATCH lower anchorages, these
child restraint systems usually require the use of
tether straps to help keep the child restraint
firmly in place .
A WARNING
Improper installation of child restraints will
increase the r isk of injury and death in a
crash.
Child safety
- Always follow the instructions provided by
the manufacturer of the child restraint you
intend to install in your vehicle.
- Never install a child restraint without a
properly attached top tether strap if the
child restraint manufacturer's instructions
require the top tether strap to be used .
- Improper use of child restraint LATCH lower
anchorage points can lead to injury in a colli­
sion . The LATCH lower anchorage points are
des igned to withstand only those loads im­
posed by correctly fitted child restraints.
- Never mount two child restraint systems on
one LATCH lower anchorage point.
- Never secure or attach any luggage or other
item to the LATCH lower anchorages.

Lower anchorages secure the child restraint in
the seat without using the vehicle's safety belts.
Anchorages provide a secure and easy-to-use at­
tachment and minim ize the possibility of improp­
er ch ild restraint insta llation .
All child restraints manufactured after Septem­
ber 1, 2002, must have lower anchorage attach­
ments for the
LATCH system .
Remember that the lower anchorage points are
only intended for installation and attachment of
child restraints specifically certified for use w ith
LATCH lower anchorages . Child restraints that
are not equipped with the lower anchorage at-
172
tachments can still be installed in compliance
with the chi ld restraint manufacturer's instruc­
tions on us ing vehicle safety be lts.
_& WARNING
Improper use of LATCH lower anchorages can
cause serious personal injury in an accident.
-Always carefully follow the ch ild restraints
manufacturer's instructions for proper in­
stallation of the child restraint and proper
use of the lower anchorages or safety belts
in your vehicle .
-Never secure or attach any luggage or other
items to the
LATCH lower anchorages .

A tether is a straight or V-shaped strap that at ­
taches the top part of a ch ild restraint to special
anchorage points in the vehicle.
T he purpose of the tether is to reduce the for­
ward movement of the chi ld restraint in a crash,
in order to help reduce the risk of head injury
that could be caused by striking the vehicle inte­
rior.
Forward facing child restraints manufactured af­
ter September 1, 1999, are requ ired by U.S . fed­
eral regulations to comply with child head move­
ment performance requirements . These new per­
formance requ irements make a tether necessary
on most new child safety seats. ..,.
