booster seat or using the vehicle safety
belt improperly increases the risk of seri­
ous personal injury and death in a collision
or ot her eme rgency s ituation. To help re­
duce t he risk of ser ious persona l injury
and/or death:
- Always make sure to position the should­
er port ion of the three -po int bel t over
the middle of chi ld's sho ulder.
- Never let the shoulder port ion of the be lt
rest against or across the neck , face,
chin, or throat of the child .
- Always make sure the lap belt portion o f
the three-po int be lt is worn sn ug and
passes as low as possib le across the
child's pelvis. Never let the belt pass over
the soft abdomen.
- Failure to properly route sa fety belts
over a ch ild's body will cause severe inju­
ries in an acc ident or other emergency
situation

seat will stay in place.
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and young­
er, should always ride in the back seat proper­ ly restrained fo r their age and weight.
.&_ WARNING
Improperly installed child safety seats in­
crease the risk of serious personal injury
and death in a collision.
- Always make sure that the safety belt re­
tractor is locked when installing a child
safety seat . An unlocked safety belt re­
tractor cannot hold the child safety seat in place during normal driving or in a
crash .
- Always buckle the child safety seat firmly
in place even if a child is not sitting in it.
A loose child safety seat can fly around
during a sudden stop or in a collision.
- Always make sure that the rear seat
backrest to which the center rear safety
belt is attached is securely latched when­
ever the rear center safety belt is being
used to secure a child restraint.
- If the backrest is not securely latched, the child and the child restraint will be
thrown forward together with the back­
rest and will strike parts of the vehicle
interior. The child can be seriously in­
jured or killed.
- Never install rearward-facing child safety
seats or infant carriers on the front pas­
senger seat . A child will be seriously in­
jured and can be killed when the passen­
ger airbag inflates.
- 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, door or roof.
- Always install rearward-facing child safe­
ty seats or infant carriers on the rear
seat. -
Forward-facing child safety seats or in­
fant carriers installed on the front pas­
senger 's seat may interfere with the de­
ployment of the airbag and cause serious
injury to the child .
- It is safer to install a forward-facing
child safety seat on the rear seat.
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used
~ page 186. Special
precautions apply when installing a child
safety seat on the front passenger seat
~ page 163, Child restraints on the front
seat -some important things to know.
.&_ WARNING
-
Always take special precautions if you
must install a forward or rearward-facing
child restraint on the front passenger's
seat in exceptional situations:
- Whenever a forward or rearward-facing
child restraint is installed on the front
passenger seat, the
PASSENGER AIR
BAG OFF light must come on and stay on
whenever the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, perform
the checks described
~ page 173, Moni­
toring the Advanced Airbag System.
- Take the child restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN­
GER AIR BAG OFF
light does not stay on
whenever the ignition is switched on.
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
tion.
- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child.
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.

-Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sensing mat and can
cause injury in a crash .
_&. WARNING
Forward-facing child restraints:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag .
- Never put the forward-facing child re­
straint up, against or very near the in­
strument panel.
-Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the forward-facing child restraint. The
backrest must be adjusted to an upright
position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on.
_&. WARNING
Rearward-facing child restraints:
- 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, door or roof.
- Always be especially careful if you must
install a rearward facing child safety seat
on the front passenger seat in exception­
al circumstances.
-A tight tether strap on a rearward-facing
child restraint attached to the front pas­
senger seat can put too much pressure
on the weight-mat in the seat and regis­
ter a heavier weight in the Advanced Air-
Child Safety 197
bag System. The heavier weight regis­
tered can make the system work as
though an adult were on the seat and de­ ploy the Advanced Airbag when it must
be suppressed causing serious or even
fatal injury to the child.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on .
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rearward-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer.

Notice about data
recorded by vehicle
control modules
Your veh icle 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.
Although 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 pe riod 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 we ll 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 stabilization
Program (ESP)
General information
The ESP improves the vehicle stability .
Fig. 195 f;. OFF button
Fig. 196 Center console wit h ~ OFF button
ESP is designed to help you maintain vehicle
control in situations where the car approaches
the limits of "grip", especia lly when accelerat­
ing and cornering . ESP reduces the risk of
skidding and improves stability under all road
conditions .
The system operates across the ent ire speed
range in combination with the ABS system . If
the Anti-Lock Brake System (ABS) malfunc­
tions, the ESP will also shut down.
How the system works
The Anti -Lock Brake System (ABS), Electronic
Differential Lock (EDL) and the Anti-Slip Regu­
lation System (ASR) are integrated in the elec­
tronic stabilization program. In addition to
the data provided by these functions, the ESP
control unit requires additional measurement
data provided by high performance sensors.
T he rotational speed of the vehicle about its
II>-

vertical axis, vehicle acceleration in the fore ­
and-aft and lateral directions , the brake pres­
sure, and the steering ang le are all measured .
The direction in which the d river wishes to
travel is determined with the aid of the steer­
ing angle and vehicle speed and is continually
compared with the actual behavior of the ve­
h icle. If the two do not match, for examp le,
when the vehicle starts hydroplaning on a wet
road, ESP will automatically brake the appro­
priate wheel to correct the problem.
The vehicle is then stabili zed by the forces act ­
ing on the wheel dur ing braking. If the vehicle
is
oversteering (the veh icle turns too sharply
and the rear wheels sl ide toward the outs ide
of a curve), the brakes are main ly applied on
the wheel that is on the outside of the curve.
I n the case of a ve hicle that is
understeering
(the vehicle does not turn sha rply enough and
pushes out of a curve) , the brakes are applied
as needed on the whee l that is on the inside of
the curve o r additiona lly on the other wheels.
An acoust ic signal indicates when ESP brake
application cuts in
q .& .
The system operates across the entire speed
range in combination with the ABS system
q page 208. If the Anti-Lock Brake System
(ABS) malfunctions, the ESP will be out of ac­
tion as well.
Acti vating
When you turn on the engine, ESP wi ll auto­
matica lly be activated and will perfo rm a se lf­
test. As soon as the test is completed, the sys­
tem is in normal operating mode .
You can activate a deactivated ESP or deacti ­
vated ESP/ASR if required by pressing the
qfig. 196 q fig . 195 button. When they are
activated, the message
Stabilisation prog ram
on
appears briefly in the d isplay.
D eacti vating
The ESP sho uld normally be activated all the
time. If necessary, you can deactivate Anti ­
Slip Regulation (ASR) or the Electron ic Stabili­
zation Program (ESP) by pressing the button

.8, WARNING -
The Electronic Stabi liz a tion Program is
neverthe less subjec t to the laws o f phys­
ics. It is part icu la rly important to pay a t­
tention to this fact on wet and slippery roads. It is therefo re important that you
a lways adapt your driving to the condit ion
of the road and traff ic conditions. Do not
allow the increased safety provided by the Elect ronic Stabilization Program system to
lull you into accepting addit iona l safety
r isks.
Electronic differential lock (EDL)
The electronic differential lock monitors the
rotational speed of the drive wheels .
General not es
The electronic d ifferential lock ( E0L) he lps the
car to star t moving, acce lerate and climb a
gradient on surfaces providing poor or almos t
no grip . Without EDL, this would be d iff icult,
if not impossible .
How the sy stem works
The EDL operates automatically. It mon itors
the rotational speed of wheels with the he lp
of the ABS sensors
q page 208 . If a noticea­
ble
slip is detected at the wheels (e .g . on s lip ­
pery ground
on one side), the sp inning wheels
are braked and power is t ransferred to the
othe r whee ls. Thi s is done up to a speed of
abo ut 60 mph (100 km/h) . Noises from the
brake system signa l that wheel spin is be ing
controlled .

206 Intelligent technology
Driving off
When driving off, a lways be sure to keep road
conditions in mind as you accelerate. If one
drive wheel spins because it is on a surface
with less grip, apply
plenty of throttle until
the car starts to
move .
Overheating of brakes
To prevent the disc b rake o f the bra ked wheel
from overheating if subjected to excessive l oads on this whee l, the EDL cuts out tempo­
rarily. The vehicle remains operational and be­
haves in the same way as a vehicle without
EDL.
As soon as the brake has coo led down, EDL
switches on again automatically .
A WARNING
-When accelerating on slippery surfaces,
such as on ice or snow, always be careful
when depressing the accelerator pedal. Even with the EDL working, the drive
wheels can spin and reduce your ability
to control your car. Risk of crash!
- The increased safety afforded by EDL
does not mean that you can take safety
risks. Always adapt your dr iving style to
the road conditions and traffic situation.
0) Tips
If a fault occurs in the ABS, the EDL is also
not funct ion ing. Thi s is indicated by the
ABS war ning light ¢
page 16.
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the
driven wheels from spinning when the car is
accelerating.
General notes
The Anti -Slip Regulation System (ASR) is inte­
grated in the electronic stabilization program
( E SP). When the vehicle starts up and acceler­
ates, the wheels are p revented from spinning
by adjusting the engine power to match the amount of grip available
from the road sur­
face.
How the system works
ASR performs automat ically, i .e. w ithout the
driver's intervention. With the aid of the ABS
sensors ¢
page 208, ASR monitors the speed
of the driven whee ls. If the whee ls start to
spin, engine torque is reduced automatica lly
until the tires find enough grip to lock onto
the road surface. The system is active across
the entire speed range.
The ASR works in conjunction with the ABS . If
a malfunction should occur in the ABS, the
ASR will also be out of act ion.
Activating
T he ESP is automatica lly activated when the
engine is started and it performs a se lf-test .
You can activate a deactivated ASR if required by pressing the
¢ page 204, fig. 196 button.
When it is act ivated, the message
ESP/ASR
on
appears briefly in the display .
Deactivating
You can deactivate the ASR if required by
pressing the button (for less than 3 seconds)
¢
page 204, fig . 196. With the ASR deactivat­
ed, the ESP check light comes on, see
¢
page 15 . The message ASR off appears in
the d isplay as well. The ASR can be deact ivat­
ed at any speed.
The ASR s hould normally be activated all the
time . Only in certain exceptional situations
when some slip is desirable does it make
sense to deact ivate the ASR . Examples :
- when driving with tire cha ins
- when driving in deep snow or on loose
ground and
- when rocking the vehicle loose after it has
become stuck.
When the abnormal situation is
over, you
shou ld activate the ASR again .

208 Intellig ent technol ogy
,8. WARNING
- You should 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 r isk -
you may cause an acc iden t!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too long or too often . This cou ld 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
stopp ing distance.
- Under certain climatic and operating
condit ions such as passing through wa­
ter, driving in heavy ra in or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice can
accumula te 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.
- Driv ing fo r an extended period of time on
salt -covered roads w ithout using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads w ith a few careful
brake applicat ions.
- 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 ent ire brake system.
- Failure of one brake c ircuit will impair
the braking capability resulting in an in­ creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­ est authorized Audi dealer or qualified
workshop.
Brake booster
The brake booster adds extra braking power .
The brake booster works with vacuum pres­
sure which is created only when the engine is
runn ing
c> .&. .
,8. WARNING
-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
been damaged, the bra ke pedal mus t be
pressed considerably harder to make up
for the lack of booster assistance.
Functioning of Anti-Lock Brake System
(ABS)
ABS prevents the wheels from locking up un­ der braking .
-
The ABS contributes effect ively to vehicle con­
trol since it prevents the whee ls from
locking
when the brakes are applied. This means that
the ve hicle remains steerable and is less likely
to skid .
With AB S you do n ot need to pump the
brake . Ju st hold th e bra ke p edal down.
However, do not expect the ABS to s horten
braking distance under
all c ircumstances.
When driving on gravel or on new ly fallen
snow on top of icy surfaces, braking dis tance
may be even longer, therefore, under these
circumstances, it is especia lly important that
you drive s low ly and with great care.
How the ABS syst em work s
An automat ic check is made when a speed o f
about 12 mph (20 km/h) is reached. When
this happens, a pumping noise can be heard.
If an ind iv idual whee l begi ns to rota te too
s lowly in re lation to vehicle speed and tends
to lock, the ABS automatically reduces brake pressure to prevent that whee l from locking . .,..

This automatic adjustment process will cause
a
slight vib ra tion of the brake pedal and some
noises to alert you that vehicle speed must be
adapted to existing road and traffic condi­
tions.
A WARNING
Although the ABS is very effective, always
remember that braking capability is limit­
ed by t ire traction . A lways adjust your dr iv­
ing speed according to the road and t raff ic
conditions. Do not let the extra sa fety af­
forded by the ABS tempt you into taking
extra risks. The ABS cannot overcome the
laws of physics .
(D Tips
-If ABS is not functioning properly, a
warning light will come on . See
~ page 16.
-If a fault occu rs in the ABS, the EDL is al­
so not functioning . This is indicated by
the ABS warning light .
Brake assist
Brake assist is designed to achieve the opti­
mum broking effect.
Brake assist helps to increase the effective
brak ing power and thus to achieve a shorter
stopping distance. If the driver presses the
brake peda l very quick ly, brake assist auto­
mat ica lly boosts the braking force to the max­

advanced power
steering system
The power steering systems uses the power of
the running engine to allow precise steering
with little effort.
T he advanced Servotronic ® power steer ing
system senses the road speed and elect ron i­
ca lly adjusts power assistance to provide com­
fortab le and safe ste ering response exact ly
matched to the vehicle speed .
Power steering will not work i f the engine is
off. As a result, the stee ring wheel will be hard
to turn .
T he power steering fluid level is checked d ur­
ing the schedu led maintenance services .
(D Note
If there is an e lectronic malfunction, ser ­
votronic
will s till function like a conven­
tiona l power steering system, providing a
constant steering support force that is no
l onger proportionate to the vehicle speed.
This is most noticeable when turning the
steering wheel at low speeds (for example
when parking), -more effort w ill be re­
q uired than usual.
- Be aware of the different than usual
steering response and adjust your steer ­
ing force acco rdingly .
- Have the problem checked and set right
by an Audi dealer as soon as possible.
(D Tips
-Whe n the engine is running, never hold
the steering w heel turned all the way to
the rig ht or to the left for longer t han 15
seconds. The powe r steering pump will
overheat the hydraulic fluid if you keep
holding the stee ring wheel turned all the
way. This is likely to damage the power
steering system .
