LATCH Lower
anchorages and tether
for children
Child Restraint System anchors and how
are they related to child safety
To provide a s impler and more pract icable way
to attach the child restraint on the vehicle
seat, Federal regu lations require special lower
anchorages in vehicles and dev ices on new
child 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
Tethers for Children ."
F orward-facing child restraints manufactured
after September 1, 1999, are required by U.S.
federal regulations to comply with new ch ild
head movement performance requirements .
T hese new performance requirements make a
tether necessary on most new child seats.
I nstalling a chi ld restraint that requires a top
tether without one can seriously impair the
performance of the chi ld restraint and its ab il­
ity to protect the child in a co llision . 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 their ch ild seats with
hook -on or push-on connectors attached to
adj ustable straps.
In addition to the LATCH lower anchorages,
these child restraint systems usually require
the use of tether straps to help keep the child
restra int firmly in place .
A WARNING
Improper insta llation of chi ld restraints
w ill increase the risk of inju ry and death in
a crash.
- Always follow the instructions p rov ided
by the manufacturer of the ch ild re-
Child S afety 1 79
straint you intend to install in your vehi­
cle.
- Never install a chi ld restraint without 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 restraint LATC H
lower anchorage points can lead to injury
in a collision . The LATC H lowe r anchorage
points ar e designed to withstand on ly
those loads imposed by correctly fitted
child restraints.
- Never mo unt two ch ild restra int systems
on one LATC H lower anchorage point.
- Never secure or a ttach any luggage or
o ther item to the LATCH lower anchorag­
es.
a) Tips
In Canada, the terms "top tether" with
"lower u niversal anchorages" (or "lower
universa l anchorage ba rs") are used to de­
scribe the sys tem.
- In other countries, the t erm " ISOFIX" is
used to describe the lower a nch o rages.

Lower anchorages secure the child restraint in
the seat without using the vehicle 's safety
belts. Anchorages provide a secure and easy­
to-use attachment and m inim ize the possibili­
ty of improper child restraint installation .
All chi ld restraints manufactured after Sep­
tember 1 , 2002, must have lower anchorage
attachments for the
LATCH system .
Remember that the lower anchorage points
are only intended for installation and attach­ ment of child restraints specifically certified
for use w ith
LATCH lower anchorages. Child
restra ints that are not equipped with the low­
e r ancho rage attachments can still be instal- led in compliance with the child restraint
manufacturer's instructions on using vehicle
safety belts
.
A WARNING
-Improper installat ion of child restra ints
will increase the risk of injury in a crash .
-A lways 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 luggage or
other items to the
LATCH lower ancho­
rages.
- Always read and heed the important in­ formation about child restraints in this
chapter and WARN INGS

Child Safety.
Installing a child restraint with LATCH
lower anchorages -
Whenever you install a child restraint always
follow the child restraint manufacturer's in­
structions.
F ig. 156 Lower a ncho rages : proper mount ing
Mounting
.. Make s ure the seatback of the rear seat
bench is in the upright posit ion and securely
latched in place.
.,. Attach both hook-on connectors with the
spring catch release on the child safety seat
onto the LATCH lower anchorage so that the
connecto rs lock i nto pla ce ¢
fig. 156.
.. Pull on the con nector attachments to make
sure they are properly a ttached to the LA T CH
lower ancho rage . ..,.

.. Pull straps tight following the child re­
straint manufacturer's instructions.
Releasing
.. Loosen the tension on the straps following
the ch ild restraint manufacturer's instr uc­
tions .
.. Depress the spring catches to re lease the
anchorage hooks from the lower anchorag­
es.
Remember: Use tether straps to help keep the
child restraint firmly in p lace.
A WARNING
Improper use of the LATCH system can in­
crease the risk of ser ious personal injury
and death in an acc ident.
- These anchors were developed only for
child safety seats us ing the "LATCH" sys­
tem.
- Never attach other child safety seats,
belts or other objects to these anchors.
- Always make sure that you hear a click
when latching the seat in place. If you do
not hear a click the seat is not secure and
cou ld fly forward and h it the interior of
the vehicle, or be ejected from the vehi­ cle.
A WARNING
Imprope r installation of ch ild restrai nts
w ill increase the risk of injury in an acc i­
de nt.
- Always fo llow the child rest raint system

T he te ther anchors for the rear seating posi­
tions are located in recesses in the rear win ­
dow shelf¢
fig. 15 7.
A tether is a stra ight or V-s haped st rap that
attaches the top par t of a ch ild restrai nt to
spe cial a nchorage po ints in the vehicle.
T he purpose of the tether is to reduce the for­
ward movement of the child rest raint in a
c rash, i n orde r to help reduce the risk of head
i njury that cou ld be caused by str ik ing the ve­
hicle inte rior .
Fo rward facing child rest raints manufactured
after September 1, 1999, are requ ired by U.S.
federa l reg ulations to comply wi th ch ild head
movement pe rformance requ irements. These
new performance requirements make a tether
necessary on most new child safety seats .
A WARNING
Improper installat ion of child restra ints
will increase the r isk of injury and death in
a crash.
-Always follow the instr uctions 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 coll ision. The anchors are de­
signed to withstand only those loads im­
posed by co rrectly fitt ed child restraints.
- Neve r mo unt two child rest ra int systems
on one LATC H lower anchor point.
- Never attach two child restraint systems
-
to one tether strap o r tethe r ancho rage . ~

182 Child Safet y
-Never attac h a tether strap to a tie-down
hook in the luggage compartment .
- Never use c hild restraint tether ancho­
rages to secure safety belts or other
kinds of occupant restra ints .
- Never secure or attach any l uggage or
other items to the LATCH lower ancho­
rages or to the tether anchors.
- If a tether or other strap is used to at­
tac h a child restraint to the front passen­
ger seat, make sure that it is not so
t ight, that it causes the weight -sensing
mat to measu re more weight than is ac­
tua lly on the seat.
- The heav ier weight reg istered can make
the Advanced Airbag System wo rk as
though an adult we re on the seat and de­
ploy the Advanced A irbag when it m ust
be s uppressed causing ser ious or even
fatal inj ury to the child.
- If you mus t install a rearward f acing
child safety seat on the front passenger
seat because of exceptional circ umstan ­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rear-facing child
safety seat in a rear seating position a nd
have the a irbag system inspected by you r
Audi dealer.

.,. Loosen the tens ion fo llowing the child re­
s traint manufa cture r's instr uctions.
.,. Depress the spring c atc h o n the hook and
release it from the ancho rage.
(D Note
If yo u leave the child restr aint w ith the
tethe r strap firm ly ins talled for several
days, this could leave a ma rk on the up­
ho lstery on the seat cushion and backrest
i n the area where the tether strap was in­
stalled. The upholstery would also be per­
manently stretched around the tether
strap . This applies espec ia lly to leather
seats .
Using tether straps on rearward-facing
child restraints
Currently, few rearward-facing child res traint
systems come w ith a tether. Please read and
heed the c hild restra int system man ufactur­
er 's instr uctions carefully to determine how to
properly install the tether .
A WARNING

Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorde r (EDR), ins talled by some manu­
facture rs fo r the express p urpose of capturing
data for retrieval after an accident or cras h
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restr ict the retr ieval 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 ltho ugh yo ur vehicle is not equ ipped wit h an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine f unction, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during norma l vehicle op­
erat ion for diagnostic and repa ir 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 ove r a ve ry limited pe riod of
time and stored when a sys tem faul t or o ther
cond ition is sensed by a cont ro l u nit. Some of
the data then stored may re late to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condit ion. Stored data can only
be read and downloaded w ith special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of ve hicle control. It works
only when the eng ine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
o ut of control and he lps you to get the veh icle
back under control by se lectively braking the
whee ls, and/or reducing eng ine power and
providing steer ing ass istance to he lp hold the
vehicle o n the dr iver's intended course. The in­
dicator light
G) in the inst rument cluster
blinks when ESC is ta king action to help yo u
control the veh icle.
ESC has limitations.
It is importa nt to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under a ll cond it ions you may come up aga inst.
F or example, ESC may not always be able to
help you master situations where there is a
s u dden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is sudden ly covered w ith water,
s lush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the ve hicle
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 in terrupted
and the vehicle cannot be braked or steered .
D uring 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 tow ing a trailer.
Always adjust your speed and driving style to road, traffic; and weather condit ions. ESC can­
not override the vehicle's physical limits, in­
crease the availab le tract ion, or keep a ve hicle
on the road if road departure is a result of
drive r inattent io n. Instead, ESC imp roves the
poss ibil ity of keeping the vehi cle under con ­
trol and on the road during ex treme maneu­
vers by using the d river's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
ca uses you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti -slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering* and electronic i nteraxle differential lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certain s ituations when you need
less traction, you can switch
off ASR by press­
i ng the button~~
page 186, fig. 159 or
~ page 186, fig. 160. Be sure to sw itch ASR
on again when you no longer need less trac­
tion.
Anti-lock b ra king s ystem (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even d uring hard brak ing . Apply ste ady p res­
sure to the brake pedal. Do not pump the ped­
a l. A pulsing in the brake peda l indicates t hat
the system is he lping you to brake the vehicle .
Brake assist system
The brake assist system can decrease bra king
d istance. It increases braking power when the
d river presses the brake pedal quick ly in eme r­
gency situations . You must press and hold the
brake peda l until the situation is over. In
veh icles w ith adaptive cru ise contro l*, the
brake assist system is more sensit ive if the
d istance detected to the veh icle ahead is too
small.
Anti- slip regulati on (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Elect ronic diffe renti al lo ck (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on again au-
Intellig ent technolog y 185
tomat ica lly when conditions have returned to
norma l.
Dynamic steering*
On vehicles with dynam ic steering*, ESC helps
stab il ize the s teer ing in crit ica l sit uat io ns.
Electronic interaxle differential lock* /
selective wheel torque control*
T he electronic i nteraxle differential lock (front
whee l dr ive) or the se lective whee l to rque
control (all-whee l dr ive) opera tes when dr iv­
ing thro ugh curves. The front wheel on the in­
side of the c urve or both whee ls on the inside
of the curve are braked selectively as needed .
This min imizes sliding in the front wheels and
allows for more precise driving through
cu rves . The applicable system may not acti­
vate when dr iv ing in wet or snowy conditions.
A WARNING
- ESC, ABS , ASR, EDL dynam ic steering*
a nd the elect ronic interaxle differential
loc k* /se lective wheel torque control*
function cannot overcome the laws of
physics. This is especially important on
slippery or wet roads . If the systems be­
gin acting to stabilize your vehicle, you
should immediately change yo ur speed
to match the road and traff ic conditions.
Do not let the increased safety provided
by these systems tempt you to take risks .
Doing so will increase the risk of a loss of
veh icle contro l, col lision and ser ious per­
sonal injuries.
- Always adapt your speed to road, traffi c
and wea ther conditions. The risk of los­
ing con tro l of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, ASR, EDL dynam ic steering* and the
electronic interaxle differentia l lock*/se­
lective whee l torque control* function
cannot prevent collisions.

186 Intelligent technology
-Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al­
ways help to reduce the risk of loss of ve­ hicle control.
(i_) Tips
- ABS and ASR only work correctly when
all four wheels are equipped with identi­
cal tires . Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working .
- If the indicator light
I] or l;S (USA
models);tl] (Canada models) appears,
there may be a malfunction ¢

Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new
brake pads do not possess their full braking
effect, they have to be "broken in" first¢& .
You can compensate for this slightly reduced braking power by pushing harder on the brake
pedal. Avoid heavy braking loads during the
break-in per iod.
Operating conditions and driv ing habits
The brakes on today's automobi les are sti ll
subject to wear, depending largely on operat ­
ing conditions and driving habits¢.&. . On
vehicles that are e ither driven mostly in stop­
and-go city traffic or are driven hard, the
brake pads should be checked by your author­
ized Audi dealer more often than specified in
the
Warranty & Maintenance booklet . Failure
to have your b rake pads inspected can result
in red uced brake performance.
On steep slopes, you shou ld use the brak ing
effect of the engine. This way, you p revent un­
necessary wear on the brake system.
If you
must use yo ur brakes, do not hold the brakes
down continuously. Pump the brakes at inter­
va ls.
Operating noise
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Effect of water and road salt
In certain situat ions, for example after driving
through water, in heavy ra in, after overnight
condensation or after washing your car, the
braking effect can be reduced by moisture or
ice on the brake roto rs and brake pads . The
brakes must be dried first with a few careful
brake applications .
A t hi gher speeds and with the windshield w ip­
ers turned on, the brake pads press against
the brake rotors for a short amount of time .
This occurs at regular intervals without the
Intelligent technology 187
driver noticing and provides for better brake
response time under wet conditions .
T he effectiveness of the brakes can be red uced
when the vehicle is driven on a sa lt-co vered
road and the b rakes are not used. Likewise,
you clean off accumulated salt coating from
brake discs and pads with a few cautious ap­
plications of the brake ¢ & .
Corrosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not driven regu larly or
on ly for short trips with litt le use of the
brakes.
If the brakes are not used frequently, or if cor ­
rosion has formed on the discs, it is advisable
to clean off the pads and discs by braking
firmly a few times from a moderately high
speed ¢.&. .
Faults in the brake system
If you should notice a sudden increase in
brake pedal trave l, then one of the two brake
c ircuits may have failed ¢.&. .
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake fluid
level is monitored electronica lly.
Brake booster
T he brake booster increases the pressure that
you generate with the brake peda l. It works
only when the engine is runn ing .¢ .&.
Brake lining wear status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the wheel. If neces­
sary, the wheel may be removed fo r this in­
spection ¢
page 252, Changing a wheel .
A WARNING
-
- New brake pads don't have the best stop­
ping power and must be "broken-in" dur-
ing the initial 100 to 150 miles (150 to
~
•
•

188 Intelligent technology
200 kilometers) of normal city driving.
You can compensate for this by pressing
the brake pedal more firmly. This also applies later when new pads are instal­
led .
- You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lowe r driving range. Do not ride
the brakes or hold the pedal down too
long or too often. This could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed . Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake c ircuit will impair
the braking capability resulting in an in­
creased stopping distance. Avoid driv ing
the vehicle and have it towed to the near- est authorized Audi dealer or
qualified
workshop.
- Never let the vehicle roll to a stop with
the engine shut off.
- If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow
