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,
Federal 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 LATCH system for
" L ower Anchorages and Tethers for Children" . In
Canada, the terms "top tether" w ith "lower uni­
versal anchorages" (or "lower universal anchor­ age bars") are used to describe the system.
In other countries the term ''ISO FIX" is used to
describe the lower anchorages .
Forward-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 serious ly impair the per­
formance of the chi ld 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 v iolation of state law.
Ch ild restraint manufacturers offer LATCH lower
anchorages on the ir ch ild seats with hook-on or
Child safety
push-on connectors attached to adjustable
straps.
In addition to the LATCH lower anchorages, these
child rest raint systems usua lly require the use of
tether straps to help keep the child restraint
firmly in place.
A WARNING
-
Improper installation of child restraints will
in crease the risk of injury and death in a
crash.
-Always follow the instructions provided by
the manufacturer of the child restraint you
intend to insta ll in your vehicle.
- Never install a child restraint without a
proper ly attached top tether strap if t he
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 LATC H lower anchorage points are
des igne d 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 o r other
item to the LA TCH 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 m inim ize the possibility of improp­
er ch ild rest raint 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
262
child restraints specifically certified for use with
LATCH lower anchorages. Child restraints that
are not equ ipped with the lower anchorage at­
tachments can still be installed in compliance
with the chi ld restraint manufacturer's instruc­
tions on us ing vehicle safety be lts .
_& WARNING
Imp roper use of LATCH lower anchorages can
cause ser ious persona l injury in an accident.
-Always carefully follow the ch ild restraints
manufact urer's ins tructions for proper in­
stallation of the child restraint and prope r
use of the lower an chor ages or safety belts
in your vehicle .
- Never secure or attach any luggage or othe r
items to the

er attachments are only designed to secure
a ch ild restraint that has been equipped to
use these anchorages .
-
Child sa fety
- Tether anchorages and lower anchorages
are designed to withstand only those loads
imposed by correctly fitted child restraints.
Under no circumstances can they be used
safely for adu lt or ch ild safety belts or har­
nesses.
- Never mount more than one child restraint to a sing le tether or to a lower anchorage
point. Attaching two child restra ints to a
sing le anchorage point can cause the an­
chorage to fail and cause serious personal
i n ju ry in a crash.
(D Note
- Remove the guidance f ixt ures before fo ld­
ing the rear seatback to preven t damag ing
the seat cushion .
- T o attach the c hild rest raint securely, the
sea t must be moved to the farthest rear po­
sition, the seat heigh t set to the lowest po­
sition and the head restraint must be ad­
justed to the vertical position.
- If you leave the guidance fixtures i nstalled
for several days, they cou ld leave a mark on
the upholstery on the seat cushion and backrest in the area that the guidance fix­
tures were installed. The upholstery would
also be permanently stretched around the
guidance fixtures. Th is applies especially to
leather seats.
