LATCH system (lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
To prov ide a simpler and more practicable way to
attach the child restra int on the vehicle seat,
F edera l regulat ions require specia l lower ancho ­
r ages in vehicles and devices on new child re­
straints to attach to the vehicle anchorages.
I n the United States, the combination of the
tether anchorages and the lowe r anchorages is
now genera lly called the LA TC H system for
" L ower Anchorages and Tethers for C hildren" . In
Canada, the terms "top tether" with "lower uni­
versal anchorages" (or "lower un iversal 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 res tra ints man ufactu red af­
ter September 1, 1999, are required by U.S. fed­
eral regulations to comply with new child head
movement performance requirements. These
Ch ild safety
new per formance requirements make a tether
necessary on most new chi ld seats.
Installing a ch ild rest raint that requires a top
tether without one can seriously impa ir the per­
formance of the child restraint and its ab ility to
protect the child in a co llision. Installing a child
restra int that requires a top tether without the
top tether may be a violat ion of state law.
Child restraint manufacturers offer LATCH lowe r
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 usua lly require the use of
tether straps to help keep the child restra int
firmly in p lace.
_&. WARNING
Improper installation of child restra ints w ill
i ncrease the risk of injury and death in a
crash.
- Always follow the instructions prov ided by
the man ufacturer of the ch ild restraint you
inte nd to install in your vehicle.
- Never i nstall a chi ld restraint without a
proper ly attached top tether strap if the
child restraint manufacture r'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 col li­
sion. The LA TC H l ower anchorage points are
des igned to w ithstand only those loads im­
posed by correctly fitted child restraints .
- Never mo unt two child res traint systems on
one LA TC H lower anchorage point.
- Never secure or at tach any luggage o r othe r
item to the LA TC H l ower anchorages.

Ancho rages prov ide a secure and easy-to- use at­
tachment and minimize the possib ility of improp­
er child restraint installat ion .
All child restraints manufact ured after Septem­
ber 1 , 2002, must have lower anchorage attach­
ments for t he
LATCH system.
Remember that the lower ancho rage points are
on ly intended for insta llation and attachment of
ch ild rest raints spec ifically certif ied for use wi th
LATCH lower anchorages. Child restraints that
are not eq uipped 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 belts.
A WARNING
Improper use of LATCH lower anchorages can
cause ser ious persona l injury in an accide nt.
- Always carefully follow the ch ild restraints
manufacturer's instructions for proper in­
stallation of the child restraint and proper
use of the lower ancho rages or safety belts
in your vehicle.
- Never secure or attach any luggage or othe r
items to the

hind the rear sea tbacks
The tether anchors for the rear seating positions
are located on the backside of the rear seatbacks
¢ fig . 129 .
A tether is a straight or V-shaped strap that at­
taches the top part of a child restraint to special
anchorage points in the veh icle.
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.

Child safety
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 safety seats.
A WARNING
Improper installation of child restraints will
increase the risk of injury and death in a
crash.
- Always follow the instructions provided by
the manufacturer of the child restraint you
intend to install in your Audi.
- Improper use of child restraint anchors (in­
cluding tether anchors) can lead to injury in
a collision. The anchors are designed to
withstand only those loads imposed by cor­
rectly fitted child restraints.
- Never mount two child restraint systems on
one LATCH lower anchor point.
- Never attach two child restraint systems to
one tether strap or tether anchorage.
- Never attach a tether strap to a tie-down
hook in the luggage compartment.
- Never use child restraint tether anchorages
to secure safety belts or other kinds of occu­ pant restraints.
- Never secure or attach any luggage or other
items to the LATCH lower anchorages or to
the tether anchors.
- If a tether or other strap is used to attach a
child restraint to the front passenger seat,
make sure that it is not so tight, that it
causes the weight-sensing mat to measure
more weight than is actually on the seat.
- The heavier weight registered can make the Advanced Airbag System work as though an
adult were on the seat and deploy the Ad­
vanced Airbag when it must be suppressed
caus ing serious or even fatal injury to the
child .
- If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
150
seating position and have the airbag system
inspected by your Audi dealer.
