LATCH Lower
anchorages and tethers
for children
Child Restraint System anchors and how
are they related to child safety
T o p rov ide a simple r and more practicable way
to a ttach the child restra int on t he vehi cle
sea t, Federal regulat ions re quire spe cial lowe r
anchorages in vehicles and devices on new
c h ild restraints to attach to the vehicle ancho­
rages.
T he comb inat io n of th e tether anc horages and
the lowe r anchorages is now genera lly c alled
t h e
LATCH system fo r "Lower Anchorages and
T ethers for Child ren."
F o rward-f ac ing ch ild res trai nts ma nufacture d
after September 1, 1999, are req uired by U .S .
f ede ra l regu lations 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 child restraint 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 chi ld restrai nt that requires a top tether
without the top tether may be a violat ion of
state law.
Child rest raint 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,
t h ese chi ld restraint systems usually require
t h e use of tethe r straps to he lp keep the ch ild
rest raint fi rmly in place.
A WARNING
-Imp roper installat ion of ch ild restra ints
will i ncrease the r is k of injury a nd dea th i n
a cr ash.
-

-Always follow the instructions provid ed
by the manufacturer of the ch i Ld re ­
straint you intend to install i n your veh i­
cle .
- Never install a child restraint without a
properly attached top tether strap if the
child restraint manufacturer's inst ruc ­
t ions requ ire the top tether strap to be
used .
- Improper use of ch ild restra int LATCH
lower anchorage points can lead to injury
in a collis ion. The LA TCH lower anchorage
points a re des igned to w ithstand only
those loads imposed by correct ly fit ted
child restraints.
- Never mou nt two chi ld restraint systems
on one LA TCH lower anchorage point .
- Never secure o r attach any luggage or
other i tem to the LATC H lower anchorag­
es .
{i) Tips
-In Canada , the terms "top tether " with
"lowe r universa l anchorages " (or "lowe r

The tether anchors for the rear seating posi­
tions are located in recesses in the rear win­
dow shelf
c> fig. 141
A tether is a straight or V-shaped strap that
attaches the top part of a child restraint to
special anchorage points in the vehicle.
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
h icle inter ior .
Forward 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 .
These new performance requirements make a
tether necessary on most new chi ld safety
seats.
A WARNING
Improper insta llation of chi ld res traints
w ill increase the risk of inju ry and death in
a c rash.
- Always follow the instructions p rov ided
by the manufacturer of the chi ld re ­
straint you intend to install in your Audi.

Description
The ESC reinforces driver safety. It reduces
the r isk of slipp ing and improves driving sta ­

Anti-lock braking system (ABS)
ABS prevents the whee ls from locking when
braking . The vehicle ca n still be steered even
dur ing ha rd braking. App ly steady pressure to
the b rake peda l. Do not pump the p edal. A
puls ing in the bra ke peda l indicates t hat the
system is acting to st abil ize the ve hicle.
Brake assist system
The brake ass ist system can decrease braking
dis tance. It increases bra king power when the
drive r presses the bra ke peda l quickly in emer­
gency s ituations. Yo u m ust pres s and hol d the
brake pedal unt il the dangerous s it u at ion is
ove r. In vehicles with adap tive c ruise control *,
the b rake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the drive
whee ls beg in spi nning and adapts the fo rce to
the road conditions . This makes it easier to
start, accelerate and dr ive up inclines.
Electronic differential lock (EDL)
The EDL bra kes whee ls tha t a re sp inning and

Electroni c inte raxle diff ere ntial lo ck */
s e le ct ive w heel t orqu e cont rol *
The electronic interaxle differential lock (front
wheel drive) or the selective wheel torque
contro l (all wheel drive) operates when driving
through curves. The front whee l on the inside
of the curve or both wheels o n the inside of
the curve are braked selectively as needed .
This minimizes s liding in the front wheels and
a llows for more precise driving through
curves. The app licab le system may not acti­
vate when driving in wet or snowy conditions .
Post-collision bra ke ass ist
"Post-collision brake assist" can ass ist the
driver during a collision by reducing the dan­
ge r of slipp ing and further co llision and by au­
tomatic braking.
"Post-collision brake assist" functions during
front, side and rear collis ions when the a irbag
control module a detects a trigger level and
the co llision takes place at a dr iv ing speed
faster than 6 mph (10 km/h). The braking of
the vehicle happen automatically via the ESC
as long as the ESC, the hydraulic brake sys­
tem, and the vehicle electrical system are not
damaged from the coll ision.
The fo llowing activ ities override the automat­
ic braking during a collision:
- If the dr iver presses the accelerator peda l.
T here is no a utomatic braking.
- When the force on the press brake pedal is
stronger than the b raking force initiated by
the system . The vehicle is manually braked .
- When the ESC is damaged and the "post­
collision brake assist" is not availab le.
A WARNING
- The ESC, ABS, ASR, EDL, electron ic inter­
axle d ifferential lock or select ive wheel
torque control cannot overcome the laws
of physics. This is espec ially important
on sl ippery o r wet roads.
If the systems
begin acting to stabili ze your veh icle, you
should immediately alter your speed to
match the road and traffic conditions . Do
not let the increased safety prov ided
tempt you into tak ing risks. This could
increase your risk of a collision.
- Please note the risk of a collision increas­
es when driving fast, especially through
curves and on slippery or wet roads, and
when dr iv ing too close to objects ahead .
ESC, ABS, the brake assist system, EDL,
electronic interaxle differentia l lock or
selective whee l to rque control cannot
p revent coll is ions.
- Press the acce lerator pedal carefully
when acce le rat ing o n even, slippe ry sur­
f a ces such as ice and snow. The drive
wheels can spin even when these control
systems are installed and this can affect
driving stability and increase the risk of a
col lision.
(D Tips
- ABS and ASR only function correc tly
when all four wheels are eq uipped w ith
identical tires. Different t ire sizes can
lead to a reduction in engine power.
- Yo u may hear noises when the systems

Brakes
New brake pads
New brake pads do not achieve their full brak­
ing effect during the first 400 km. They must
be "broken in" first. However, you can com­
pensate fo r the slightly reduced braking force ""

188 Smart Technology
by pressing firmly on the brake pedal. Avoid
heavy braking during the break-in period.
Wear Brake pad
wear is largely dependent on the
way the vehicle is driven and on operating
conditions. This is especially true if you are
driving frequently in the city and on curves or
with a sporty driving style.
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 situations, for example after driving
through water, in heavy rain, after overnight
condensation or after washing your car, the
braking effect can be reduced by moisture or
ice on the brake rotors and brake pads. The
brakes must be "dried" first with a few careful
brake applications.
At higher speeds and with the windshield wip­
ers turned on, the brake pads press against
the brake rotors for a short amount of time.
This action which is not felt by the driver hap­
pens at regular intervals and facilitates a bet­
ter reaction time for the brakes in wet weath­
er.
The braking effect can also be reduced if you
are driving on salted roads and you do not ap­ ply the brakes for long periods of time. The
layer of salt on the brake rotors and pads
must be worn off first when the brakes are ap­
plied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avoiding heavy braking
can contribute to corrosion on the brake ro ­
tors and dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy braking at
high speeds is recommended to clean the
brake rotors and pads
Q &. .
Brake system malfunction
if you notice that the brake pedal travel has
suddenly gotten larger, then a brake circuit
may have failed. Drive to your authorized Audi
dealer or qualified repair facility immediately
to have the problem corrected. On the way
there, drive with reduced speed and keep in
mind that a long braking distance and in­
creased pressure on the brake pedal will be
necessary.
Low brake fluid level
When the brake fluid level is low, malfunc­
tions in the brake system may occur. The brake fluid level is electronically monitored .
Brake booster
The brake booster amplifies the pressure you
apply to the brake pedal. It only works when
the engine is running.
A WARNING
-- 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 accident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower 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
