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 for "Lower 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 189
federa l reg ulations to comply with new child
head movement performance requirements.
These new performance requirements 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 collis ion. Insta lling
a child restraint that 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 with
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 help keep the ch ild
restraint firmly in place.
A WARNING
Imp roper 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 LATCH lower anchorage point.
- Never secure or attach any luggage or
other item to the LATCH lower anchorag-

Lower anchorages secure the child res train t in
the seat without using the vehicle's safety belts . Anchorages provide a secure and easy­
to-use attachment and minimize the possibili­
ty of improper ch ild restra int installation.
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 with 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

child restraint manufacturer's instructions .
.,. Push down on the seat cushion so that the
lower anchorages are v isible .
.,. Pull off the gu idance fixtures from the low ­
er anchorages .
.,. Always remove the guidance fixtures and
keep them in a safe p lace when not in use.
You may find it easier to install ch ild re­
stra ints equipped with hooks attached to
straps without the guidance fixtures 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 .
- Always 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
occupant 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 ncho rages.
- Tethe r anchorages and lower anchorages
are designed to withstand only those loads imposed by correc tly fitted child
restraints. Under no ci rcumstance 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 176, 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 60.
-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 63. 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 193
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
the Advanced Airbag System work as
though an adult were on the seat and de -
ploy the Advanced Airbag when it must ..,

196 Audi pre sense
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).
Vehicles with Aud i drive select*: the dep loy­
ment time is adapted in dynamic mode.
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 collision the following functions can be
tr iggered :
- Braking guard
c::> page 99
- Tightening the safety be lts
- 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 collision with the vehicle
coming from behind is also calcu lated.
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 optim ized for the front seats and
the outboard 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 rear.
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 o f 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
c::> page 93.
-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 be ing ac­
curately detected and in some cases they
may not be detected at all.

198 Intellige nt tec hno logy
Intelligent technology
Notice about data
recorded by veh ic le
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retrieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for example, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as well as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stab ilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the vehicle back under control by selectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It will not always be able to help out
under a ll cond itions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it would on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not towing a trailer.
Always adjust your speed and driving style to road, traffic; and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
driver inattent ion. Instead, ESC improves the
possibility of keeping the vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

A layer of ice or frost in the cooler interferes
with its cooling performance.
Cl ean ing
The refr igerator sho uld be cleaned regularly.
.. Wash the cooler w ith lukewarm water and a
mild cleaning solut ion, if necessary .
.. The n wipe the cooler dry.
.. Dust and dirt will accumu late near the ven­
t il ation openings in the luggage compar t­
ment due to normal cooler usage. This
should be cleaned regularly.
Defrost ing
.. Swi tch the cooler off¢ page 75.
.. Remove any food or beve rages and al low

gine compartment.
Always switch off the ign it ion before cle an­
i ng th e eng in e¢ .&. .
Plenum panel
Remove leaves from the plenum panel i n front
of the windshield under the engine compart­
ment. This prevents the water drain holes
from becoming b locked, and it prevents de­
bris from entering the vehicle interior through
the heat ing and ventilat ion ducts .
Corrosi on protect ion
The engine compartment and transmission
have been corrosion-protected at the factory .
Good anti-corrosion treatment is very impor ­
tant, partic ularly in the winter.
If the vehicle
is frequently driven on salt treated roads, the
entire engine compartment and plenum panel
shou ld be thoroughly cleaned at the end of
winter and retreated to prevent salt damage .
At the same time, the underside of t he veh icle
shou ld be washed as well.
If the engine compartment is cleaned at any
time with grease remov ing solutions
1>, or if
you have the engine washed, the anti-corro­
s ion treatment is almost a lways removed as
well . It is therefo re esse ntia l to have a lo ng­
lasti ng corrosion pro te ct ion reapplied to all
surfaces, seams, joints and components in the
engine compartment .
A WARNING
