A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury .
-Adjust the steer ing whee l co lumn on ly
when the vehicle is not moving to pre­
vent loss of veh icle control.
-
- Adjust the driver's seat or steering whee l
so that there is a m inimum of 10 inches
(25 cm) between your chest and the
steer ing whee l

you cannot maintain th is m inimum dis­
tance, the a irbag system cannot protect
you properly.
- If physical limitations prevent you from
sitting 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive equ ipment is ava ilable .
- If the steer ing whee l is aligned with your
face, the supplementa l dr iver's a irbag
cannot provide as much protection in an
accident. Always make sure that the
steer ing whee l is aligned with your

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 .

A WARNING ,~
The increased safety afforded by ASR does
not mean that you can take safety r isks .
Always adapt your driv ing style to the road
conditions and traffic situation .
@ Tips
To ensure that the ASR works properly, all
four wheels must be fitted with identical
tires. Any differences in rolling radius of
the t ires can cause the system to reduce
engine power when this is no t des ired. See
also ¢
page 263, New tires and replacing
tires and wheels.
Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automob iles are st ill
subject to wea r, depend ing largely on operat ­
ing conditions and dr iving habits ~.&. . On ve­
h icles that are either driven mostly in stop­
and-go city traffic or are driven hard, the
brake pads should be checked by your a uthor­
ized Audi dealer more often than specified i n
the
Warranty & Maintenan ce booklet . Failure
to have your brake pads inspected can result
in red uced brake performance.
On steep slopes, you should use the brak ing
effect of the eng ine . This way, you p revent un­
n ecessary wea r on the brake system . If you
must use you r brakes, do not ho ld the bra kes
down continuously . Pu mp the b rakes at in ter ­
va ls.
Noises may occur when braking depending on
the speed, bra king for ce and outside condi­
tions s uch as temperatu re a nd humidity .
Moisture or road salt
If you are driving faster than 31 mph (SO km/
h) and the windsh ie ld w ipers are on, the brake
pads will briefly touch the b rake d iscs in regu­
l ar i nte rva ls so as to imp rove reaction t ime
Int ellig ent technolog y 207
when b rak ing on wet surfaces . You, the driver,
will not notice anything.
U nder certa in cond itions , fo r example, when
d riv ing th rough wa ter or very heavy ra in , or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads. A
few carefu l brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the brakes can be red uced
when the vehicle is driven on a salt-covered
road and the brakes are not used. Here too,
you should clean off accumulated salt coating
from brake discs and pads w ith a few careful
applications of the brake¢,&. .
Corrosi on
There may be a tendency for dirt to b uild up
on the brake pads and corros ion to form on
the d iscs if the car is not driven regularly or
o nly for short trips w ith litt le use of the
brakes .
If the brakes are no t used frequently, or if cor­
ros ion has formed on the discs, i t is adv isable
to clean off the pads and d iscs by braking
firmly a few times from a moderately high speed ¢,& .
Fault s in the brake s ystem
If you should notice a sudden increase in
brake pedal trave l, then one of the two brake
c ircuits may have failed ¢,&. .
Lo w br ake fluid le vel
Malfunctions can occ ur in the brake system if
the brake fluid level is too low. The brake flu id
level is monitored electronically.
Brake lining wea r status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the open ings in the wheel. If neces­
sary, the wheel may be removed for th is in­
spection ¢

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
imum level, up to the point where the anti­
lock brake function (ABS) intervenes to stop
the wheels from locking . You should then
keep the brake pedal pressed u ntil the vehicle
has braked to the required speed . Brake ass ist
sw itches itself off as soon as you release the
b rake peda l.
A WARNING
Please remembe r that the accident r is k al­
ways increases if yo u drive too fast, espe ­
cially in corners or on a s lippery road, or if
you fo llow the vehicle ahead of you too
close ly. Increased risk of an accident can-
Int ellig ent technolog y 209
not be compensated for even by brake as­
sist, so always maintain a safe speed.

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 .

212 Intelligent technology
If starting capability is jeopardized due to en­
ergy consumption, the following warning ap­
pears in the MMI display:
Please start engine, otherwise system will
switch off in 3 minutes.
The warning ind icates that the system will be
turned off automatically after 3 minutes. If
you wish to continue using the functions, you
have to start the engine .
With the engine running
Although electrical energy is generated when
the vehicle is be ing driven, the battery can be­
come discharged . Thi s happens mostly when
little ene rgy is being generated and a great
deal consumed and the battery's state o f
charge is not optima l.
To bring the energy balance back into equili­
brium, consumers which require especially
l arge amounts of energy are temporarily cut
back or switched off. Heating systems in par­
ticular require a great dea l of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporar ily cut back or switched
off. These systems will be ava ilable again as
soon as the energy balance has been restored.
You will also notice that engine idle speed has
been increased slightly. This is normal and not
a cause for concern . By increas ing engine idle
speed the add itiona l energy required is gener­
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, this is shown in the instrument cluster display
with the following driver message:
(•i Low battery charge : battery will be
charged while driving
This notif ication reminds you that the starting
