T he tether anchors for the rea r seating pos itions
are located on the backside of the rear seatbacks
¢ fig . 181 .
A tether is a straight o r V-shaped strap that a t
t a ches the top p art of a ch ild rest raint to spe cial
anchorage points in the ve hicle .
T he purpose of the tether is to reduce the for
ward movement of t he ch ild restrain t in a crash,
in order to help reduce the risk of head inju ry
that co uld be caused by striking the vehicle inte
rior.
Forward facing child restra in ts manufac tured af
ter September 1, 1999, are requ ired by U.S . fed
er al reg ulations to comply with new child head
movement performance req uirements. These
new performance requ irements mak e a t ether
necessary on most new chi ld safety seats.
A WARNING
-
Improper installation of child restra ints w ill
i ncrease the risk of injury and death in a
crash .
- Always follow the instructions prov ided by
the ma nufact urer of the ch ild restraint you
i n tend to install in your Audi .
- Improper use of chi ld restraint anchors ( in
cluding tether anchors) can lead to injury in
a co llision . The anchors are designed to
withstand only those loads imposed by cor

Child safety
-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 chil d restraint tether anchorages
to secure safety belts or other kinds of occu
pant restraints.
- Never secure or attach any luggage or other
items to the LATCH lower anchorages or to
the tether anchors.
- If a tether or other strap is used to attach a
child restraint to the front passenger seat,
make sure that it is not so tight, that it
causes the we ight-sens ing mat to measure
more weight than is actually on the seat.
- The heav ier we ight registered can make the
Advanced Airbag System work as though an
adul t were on the seat and deploy the Ad
vanced Airbag when it must be suppressed ca using se rious or even fatal inju ry to the
child.
- If you must install a rearward fac ing ch ild
safety seat on the front passenger seat be
ca use of exceptiona l circumsta nces and the
PAS SENGER AIR BAG OFF light does not
come on and stay on, immediate ly install

would also be permanently stretched around
the tether strap. This applies especially to
leather seats.
Using tether straps on rearward-facing
child restraints
Currently, few rear-facing child restraint systems
come with a tether . Please read and heed the
child restraint system manufacturer's instruc
tions carefully to determine how to properly in
stall the tether.
A WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the front
airbag inflates -even with an Advanced Airbag
System.
- The inflating airbag will hit the child safety seat or infant carrier with great force and
will smash the child safety seat and child against the backrest, center armrest, or
door .
-A tight tether or other strap on a rearward
facing child restraint attached to the front
passenger seat can put too much pressure
on the weight-mat in the seat and register a
heavier weight in the Advanced Airbag Sys
tem. The heavier weight registered can make the system work as though an adult
were on the seat and deploy the Advanced
Airbag when it must be suppressed causing serious or even fatal injury to the child.
- If you must install a rearward facing child
safety seat on the front passenger seat be
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating position and have the airbag system
inspected by your Audi dealer.

Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) reinfor
ces driver safety . It reduces the risk of slipping
and improves driving stability. ESC detects crit i
cal s ituations such as the vehicle oversteering
and understeering or the wheels sp inning. The
veh icle is stab ilized by applying the brakes or re
ducing engine torque . Once t he ESC is active, the
indicator light
Ji) blinks in t he instrument clus
ter.
The fo llow ing systems are integrated in the ESC :
Ant i-loc k brake system (ABS)
ABS preve nts the wheels from locking up when
braking. The veh icle can still be steered even dur
ing hard brak ing. Apply steady pressure to the
brake pedal. Do not pump t he pedal. A pulsing in
the brake pedal indicates that the system is help
i n g you to brake the vehicle .
Br ake assist system
The brake assist system can decrease brak ing dis
tance . It increases braking power when the driver
presses the brake pedal quick ly in emergency sit
uations . You must press and hold the b rake pedal
until the situa tion is over. In vehicles w it h adap
tive c ruise contro l* , the brake assist system is
mo re sensit ive if the di stance de te cte d to the ve
h icle ahead is too small.
Anti -slip regulation (ASR)
ASR reduces eng ine power when the drive wheels
begin to spin and adapts t he force to the road
conditions . This makes it easie r to sta rt, acceler
ate and dr ive up h ills.
Electronic differential lock (EDL )
The EDL brakes w heels that a re spinning and
transfers the drive power to the other whee ls .
This f unction is not avai lab le at higher speeds.
In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
186
overheating . EDL will sw itch on again automati
ca lly when conditions have returned to normal.
Steering recommendation
The ESC he lps to s tabilize the vehicle by chang ing
t h e s teer ing torque.
On vehicles with dynam ic steeri ng*, ESC helps
stab ilize the steer ing in crit ica l sit uat io ns.
Selective wheel torque control
Se lective wheel torque cont rol is used when driv
i ng on curves. The front whee l on the inside of
the curve or both wheels on the inside of the cu rve are braked se lectively as needed. This al
l ows mo re precise dr iving in c urves . The applica
ble system may not ac tiv ate when d riving in wet
o r snowy cond it ions.
_&. WARNING
- The ESC and i ts in teg ra ted systems can not
overcome the laws of physics . This is espe
cially important on slippery or wet roads. If
the systems begin act ing to stab ilize your
veh icle, you should immediately change
your speed to match the road and traffic conditions. Do not let the increased safety
provided by t hese systems tempt yo u to
take risks. Doing so will i ncrease the r isk of
a loss of vehicle con trol, collisi on and se ri
ous person al injur ies.
- Always a dapt your speed to road, traffic and
weather condi tions. The risk of los ing c on
t rol of the vehicle in creases w hen driving
too fast, es pecially through curves and on
slippe ry or wet roads, and when driving too
close to ve hicles up ahead. The ESC and its
integ rated systems cannot always prevent
col lisions - there is still a risk of accidents!
- Always accelerate w ith special care on even,
smooth su rfaces s uch as those that are wet
or covered wit h ice and snow. The drive
wheels can spin even w it h these assistance
sys tems t hat cannot a lways help to reduce
t he risk of loss of vehicle co ntro l.

derstanding how a vehicle 's systems performed.
The EDR is designed to record da ta rela ted to ve
hicle dynamics and safety systems for a short pe
riod of time, typically 30 seconds or less . The
E DR in th is veh icle is des igned to record such da
ta as:
- How various systems in your vehicle were oper
at ing;
- Whether o r not the driver and passenger safety
belts were buckled/fastened;
- How far ( if at all) the dr iver was depressing the
acce lerator and/or brake peda l; and,
- How fast the vehicle was trave ling.
These da ta ca n he lp provide a better understand
ing of the ci rcumstances in which crashes and in
juries occur. NO TE: EDR data are reco rded by your
vehicle only if a non-triv ia l 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 re
corded . H owever, other parties, such as law en
forcement, could combine the EDR data w ith the
type of personally identify ing dat a routine ly ac
q uir ed dur ing a crash invest iga tion.
To read data reco rded by an EDR, specia l equip

Intelligent Technology
Braking
What affects braking efficiency?
New brake pads
During the firs t 25 0 miles (400 km), new b rake
pads do not possess their full braking effect , they
have to be "broken i n" first ¢& .
Operating conditions and driving habits
The brakes on today 's automobiles a re sti ll sub
ject to wea r, depend ing la rgely on ope rating con
d itions and dr iv ing habits
c::> .&,. . On veh icles that
are either dr iven most ly in stop-and -go city traf
f ic or are driven hard, the brake pads should be
checked by your authorized Audi dea ler more of
ten than spec ified in the
Warr ant y & Ma inte
nance booklet .
Failure to have your brake pads
inspected can result in reduced brake perform
ance .
On steep slopes, you shou ld use the braking ef
fect of the eng ine. This way, you prevent unnec
essary wear on t he brake system . If you must use
your brakes , do not hold the brakes down cont in
uously . Pump the brakes at interva ls.
Oper ating noise
Noises may occur when braking depend ing on the
speed, braking force and outs ide cond itions such
as temperature and humidity .
Effect of wat er and road salt
In certain s ituations, for example after driving
through water, in heavy ra in, after overnight con
densat ion or after washing your car, the braking
effect can be reduced by moisture or ice on the brake rotors and b rake pads . The brakes must be
dried first with a few careful b rake applications.
At higher speeds and with the windshie ld wipers
turned on, the brake pads press aga inst the brake
rotors for a short amount of t ime. Th is occurs at
regular intervals w ithout the driver noticing and
provides fo r bette r brake response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered road
and the brakes a re not used . Likewise , you clean
off acc umu lated salt coat ing from brake d iscs
190
and pads with a few cautious app lications of the
bra ke
c::> & .
Corrosion
There may be a tendency fo r dirt to build up on
the b rake pads and corrosion to form on the discs
if the car is not dr iven regu la rly or only for short
trips wi th little use of the brakes .
If the bra kes are not used frequent ly, o r if cor ro
s io n has formed on the discs , it is advisable to
clean off the pads and discs by b rak ing firmly a
few times from a moderately high speed
c::> & .
Faults in the brake system
If you s hou ld notice a sudden increase in brake
pedal travel, then one of the two brake circu its
may have fai led ¢
_&.
Low brake fluid level
Malfunctions can occur in the brake system if the
brake fluid level is too low . The brake fluid level
i s monitored electronically.
Brake booster
The brake booster increases the pressure that
you generate with the brake pedal. It only oper
ates wh ile the eng ine is r unning or w ith the igni
tion switched on (hybr id drive *) ¢ & .
Brake lining wear statu s
Brake lining wear may be checked by visual in
spection of the condition of the brake pads
through the openings in the wheel. If necessary,
the wheel may be removed for t his inspection
¢page 255, Replacing wheels .
A WARNING
-New brake pads do n't have the best s top
ping power and m ust be "broken-in" du ring
the initial 250 miles (400 km) . You can
compensate for this by pressing the brake pedal more firmly . This a lso applies later
when new pads are installed.
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system
only if road condit ions permit. Other road
users must not be put at risk -you may
cause an accident!
