LATCH Lower
anchorages and tethers
for children
Child Restraint System anchors and how
are they related to child safety
To provide a s imp le r and more pract icable way
to attach the ch ild res traint on the veh icle
seat, Federa l regu lations require specia l lower
anchorages in vehicles and devices on new
chi ld restraints to attach to the vehicle ancho­
rages.
The combination of the tether anchorages and the lower anchorages is now generally called
the
LA TCH system fo r "L ower Anchorages and
T ethers for Children."
F orward- facing child restraints manufactured
after September 1, 1999, are required by U .S.
Child Sa fet y 187
federa l reg ulations to comply with new child
head movement performance req uirements.
These new performance req uirements make a
tether necessary on most new child seats.
Installing a ch ild restra int that requires a top
tethe r without one can seriously impair the
performance of the c hild restra int and its abil ­
ity to protect the child in a coll is ion. Insta lling
a child res traint tha t requires a top tether
without the top tether may be a violat ion of
state law.
Child restraint manufacturers offer LATCH
lower anchorages on their child seats w ith
hook -on or push-on connectors attached to
adjustable straps .
In add ition to the LATCH lower anchorages,
these child restraint systems usually require
the use of tether straps to he lp keep the ch ild
restraint firmly in place .
A WARNING
Improper installat ion of child restra ints
will increase the r isk of injury a nd death in
a cr ash.
- Always follow the instr uctions provided
by the manufa cture r of the child re­
s traint yo u intend to install in your vehi­
cle.
- Never inst all a child restraint withou t a
properly attached top tether strap if the
child restraint manufacturer's instruc ­
tions require the top tether strap to be
used.
- Improper use of child rest raint LATCH
lowe r ancho rage points can lead to injury
in a collision . The LATCH lower anchorage
points are designed to withstand on ly
those loads imposed by correctly fitted
child restraints .
- Never mount two child restra int systems
on one LATC H lower anchorage point.
- Never secure or attach any luggage or
other item to the LATCH lower anchorag-

@ Tips
-In Canada, the terms "top tether" with
"lower universa l anchorages" (or "lower
universal anchorage bars") are used to
describe the system.
- In other countries, the term "ISO FIX" is used to describe the lower anchorages .

¢ fig . 182.
Lower anchorages secure the chi ld res train t in
the seat without using the vehicle's safety belts . Ancho rages provide a secure and easy­
to-use attachment and minimize the possibili­
ty of imp roper ch ild restra int installa tion.
All child restraints manufactured after Sep ­
tember 1, 2002 , must have lower anchorage
attachments for the
LATCH system.
Remember that the lower anchorage po ints
are o nly intended for installation and attach ­
ment of child restraints specifically certified
for use with
LATCH lower anchorages. Chi ld
rest raints that are not equipped wi th the low­
er anchorage attachments can still be insta l­
led in compliance with the child restraint
manufacturer 's instructions on us ing vehicle
safety belts .
Ln._ WARNING
-Improper use of LATCH lower anchorages
can cause serious personal injury in an ac­
cident.
- Always carefu lly follow the child re­
straints manufacturer's instructions for
proper installation of the child restraint

and proper use of the lower anchorages
or safety belts in your vehicle.
- Never secure or attach any l uggage or
other items to the
LATCH lower ancho ­
rages .
- Always read and heed the important in­
formation about child restra ints in this

You may find it easier to install ch ild re­
stra ints equipped with hooks attached to
straps without the guidance fixtu res in place .
If this is the case, remove the guidance fix­
tures by pulling them off the anchorages. However, the guidance fixtures can help you
to locate the
LATCH anchorages.
A WARNING
Improper use of tether anchorages or low­
er anchorages can cause serious personal injury in a crash .
- A lways carefully follow the child re­
straint manufacturer's instructions for proper insta llation and use of child re­
straint systems .
- Never use the
LATCH or tether anchorag­
es to attach safety belts or other k inds of
occ upant restra ints .
- Ch ild restraint tether attachments and
lower attachments are only designed to
secure a ch ild restraint that has been
equ ipped to use these a nc ho rages.
- Tethe r anchorages and lower anchorages
are designed to withstand only those loads imposed by correc tly fitted child
restraints. Under no cir cumstance s can
they be used safely for adult or child
safety belts or harnesses .

-Always read and heed the important in­
formation and WARNINGS about child
safety and the installation of child re­
straint systems
c:> page 174, Child Safe­
ty.
(D Note
On vehicles with power adjustable rear
seats* some criteria must be observed
when attaching the child restraint using the
LATCH system:
- To attach the child restraint securely, the
seat must be moved to the farthest rear
position, the seat height set to the low­
est position and the head restraint must be adjusted to the vertical position
¢ page 61.
-If a child safety seat is attached to one of
the rear seats, this seat must not be ad­
justed using the power controls under
any circumstances. The
Entry assistance
for this seat must also be deactivated in
the MMI ¢
page 64. The child safety seat
as well as the rear seat can be damaged by the adjustment process.
Tether anchors and tether straps
Fig. 186 Tether an cho rs: reces s fl ap s b ehin d th e re ar
seatbacks
The tether anchors for the two* /three rear
seating positions are located in recesses in the
rear window shelf ¢
fig. 186. Vehicles with
two rear seating positions* are equipped with two tether anchors .
A tether is a straight orV-shaped strap that
attaches the top part of a child restraint to
special anchorage points in the vehicle.
Child Safety 191
The purpose of the tether is to reduce the for­
ward movement of the child restraint in a
crash, in order to help reduce the risk of head
injury that could be caused by striking the ve­
hicle interior .
Forward facing child restra ints manufactured
after September 1, 1999, are required by U.S.
federal regulations to comply with new child
head movement performance requirements.
These new performance requirements make a
tether necessary on most new child safety
seats .
.&_ 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 re­
straint you intend to install in your Audi.
- Improper use of child restraint anchors
(including tether anchors) can lead to in­
jury in a collision . The anchors are de­
signed to withstand only those loads im­
posed by correctly 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 ancho­
rages to secure safety belts or other
kinds of occupant restraints.
- Never secure or attach any luggage or
other items to the LATCH lower ancho­ rages or to the tether anchors .
- If a tether or other strap is used to at­
tach a child restraint to the front passen­ ger seat, make sure that it is not so
tight, that it causes the weight -sensing
mat to measure more weight than is ac­
tually on the seat .
- The heavier weight registered can make

Audi pre sense
Preventative passenger
protection
A pp lies to veh icles: with Audi pre se nse
Audi pre sense can initiate steps to help pro­
tect vehicle occupants in certain situations.
The functions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic
The following functions can be triggered in
certain driving situations:
- Tightening of the safety belts (for example,
during heavy braking) : the front safety belts
have reversible belt pretensioners. If a colli­
sion does not occur, the safety belts loosen
slightly and are ready to be tightened again.
- Closing the windows and the sunroof*: the
windows and the sunroof* close leaving a
small open gap.
Audi pre sense basic functions can be trig­
gered at speeds above 20 mph (30 km/h). The
deployment time is adapted in the drive select
mode dynamic.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the
limits of the system, the likelihood of a colli­
sion with the vehicle immediately ahead is al­
so calculated .
If the system senses an immi­
nent collis io n the following functions can be
triggered:
- Braking guard
~page 98
-Tightening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi pre sense rear includes the functions in
Audi pre sense basic. In addition, the likeli­
hood of a rear-end coll ision with the veh icle
coming from behind is also calculated. If the risk
of a co llision is detected, the following
functions can be triggered:
- Tig htening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
- Adjusting the seats: the settings for the
power head restrains, the upper sections of
the backrests and the pneumatic side bol­
sters* are optimized for the front seats and
the outboa rd rear seats*. If a collision does
not occur, the previous seat settings are re­
stored.
Audi pre sense plus
Audi pre sense plus includes the funct ions in
Audi pre sense front and Audi pre sense rea r.
Error message
Audi pre sense: not available
Preventative passenger protection is not avail­
able. See your authorized Audi dealer immedi­
ately to have the malfunction corrected .
A WARNING
-Audi pre sense cannot overcome the laws
of physics.
It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the risk of a collision and serious personal
injuries.
- The sensors cannot always detect all ob­
jects . This increases the risk of a colli­
sion.
- Audi pre sense does not detect people or
animals or objects that are crossing the
vehicle's path~
page 92.
-The radar sensor's vision can be reduced
by heavy rain, ice, snow, heavy road spray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from being ac­
curately detected and in some cases they
may not be detected at all.

Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
E ve nt Data Recorder
This vehicle is equipped with an Event Data
Recorder (EDR) . The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an airbag deployment or hitting a road obstacle, data that will assist in
understand ing how a veh icle's systems per­
formed. The EDR is designed to record data
re lated to vehicle dynamics and safety sys­
tems for a short period of time, typically
30 seconds or less. The EDR in this vehicle is
designed to record such data as:
- How various systems in you r vehicle were
operating;
- Whether or not the d river and passenger
safety belts were buckled/fastened;
- How far (if at all) the driver was dep ress ing
the accelerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can help provide a better under­
stand ing of the cir cumstances in which crash­
es and injuries occur . NOTE : EDR data are re­
corded by your vehicle only if a non-trivial
crash situation occurs; no data are recorded by
the EDR under normal driving conditions and
no personal data (e.g., name, gender, age,
and crash location) are recorded. However,
other parties, such as law enforcement, cou ld
comb ine the EDR data with the type of per­
sonally identifying data routinely acquired
during a crash investigation.
To read data recorded by an EDR, special
equipment is required, and access to the vehi­
cle or the EDR is needed. In addition to the ve­ hicle manufacturer, other parties, such as law
enforcement, that have the special equip­
ment, can read the information if they have
access to the vehicle or the EDR. Some state
laws restrict the retrieval or down­
loading of data stored by ED Rs installed in a
vehicle for the express purpose of retrieving
data after an accident or crash event without
the owner's consent .
Audi will not access the EDR and/or simi lar
data or g ive it to others -
- un less the vehicle owner (or lessee if the ve ­
hicle has been leased) agrees; or
- upon the official request by the police; or
- upon the ord er of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the ju­
dicia l discovery p rocess.
- Aud i may also use the data for research
about vehicle operat ion and safety perform­
ance or provide the data to a third party for
research purposes without identifying the
specif ic vehicle or information about the
identity of its owner or lessee and only after
the recorded vehicle data has been ac­
cessed.
Vehicle control modules
You r vehicle is also equ ipped with a number of
electron ic control modules for various vehicle
systems, such as engine management, emis­
sion control, airbags, and safety belts.
T hese electronic control mod ules record data
during norma l vehicle operation that may be
needed by trained technicians for diagnostic
and repair purposes. The recording capability
of these modu les is limited to data (no sound
is recorded). Only a small amount of data is
actually recorded over a very lim ited period of
t ime, or stored when a system fault is detect­
ed by a contro l modu le. Some of the data
stored may relate to vehicle speed, direction,
o r braking, as well as restraint system use and
performance in the event of a crash. Stored
data can also only be read and downloaded
with special equipment that is directly con-
nected to the vehicle. .,..
