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

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

control modules
Your veh icle is not equipped with an Event Da­
ta Recorde r (EO R), installed by some manu­
facture rs fo r the express purpose o f capturing
data for retr ieval after an accident or cras h
event . EDR's a re sometimes called "crash re ­

Some state laws res trict the retr ieval or down ­
l oadi ng of data stored by E DR's that were in ­
stalled in a veh icle for the exp ress purpose of
retrieving data after an accide nt or crash
event w ithout the owner's consent.
A lthough yo ur vehicle is no t equ ipped w it h an
EDR, it is equipped with a number of elect ron­
ic control modules fo r various vehicle systems
such as, for examp le, eng ine f unction, em is­
sion control, as well as for the airbags and
safety belt s.
These electronic contro l modules also record
veh icle -re lated data dur ing no rma l veh icle op­
erat ion for d iagnostic and repa ir purposes .
T he 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

Electronic stabilization
control (ESC)
Description
The ESC reinforces driver safety. It reduces
the r isk of slipp ing and improves driving sta ­
b ili ty . E SC detects cr itical s it u ations such as
the veh icle ove rsteer ing and understee ring or

th e wheels a re sp inning . The vehicle is stabi ­
li zed by applying the brakes or red ucing en­

ment cluster.
The anti-lock braking system (ABS), brake as­ s ist system, ant i-slip regu lation (ASR), e lec­
tron ic different ia l loc k (EDU, electron ic differ ­

bilization of the vehicle th rough a change in
t h e s teer ing torq ue.
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
trans fers the dr ive power to the othe r drive

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
described are working .
- If the

for a test. Brakes will dry and ice coat­ings will be cleaned off after a few
careful 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 circuit will impair
the braking capability resulting in an in­
creased stopping distance. Avoid driving
the vehicle and have it towed to the near­
est 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, the
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance.
(D Note
- Never let the brakes "rub" by pressing
the pedal lightly when braking is not really necessary. This causes the brakes
to overheat and increases braking dis­
tance and causes wear.
- Before driving on a long stretch with
steep slopes, reduce your speed and shift
to the next lower gear This makes use of
the engine braking effect and relieves
the brakes. If you need to brake addition­
ally, brake in intervals and not continu­
ously.
(D Tips
- If the brake booster is not working, you
must press the brake pedal with much
more force then normal.
- If you retrofit your vehicle with a front
spoiler, wheel covers or similar items,
Smart Technology 189
make sure that the air flow to the front
wheels is not interrupted. Otherwise the
brake system can become too hot.
Electromechanical
steering
The electromechanical steering supports the
driver's steering movements.
Power steering adapts electronically based on
the vehicle speed.
The vehicle still has full steering functionality if the power steering fails or when the engine
is stopped (towing) . To steer, you must apply
much more force than usual.
