Switching ESC off (sport mode )
In certain situat ions, it m ight make sense to
allow some sl ip. For example :
- Rocking the vehicle to free it when it is stuck
- Driv ing in deep snow or on loose ground
- Driving with snow chains
Press the~ button . The ESC ind icator light
II
turns on and Stabilization prog ram off ap­
pears in the d isplay. ASR deactivates com­
p letely and the stabi lizat ion effects from the
ESC system are limited .
Switch ing on
Press the~ button again. The message Stabi­
li zation p rogram on
appears briefly in the dis­
p lay.
A WARNING
Only switch ESC sport mode on when your
driving abilities and the traffic s ituation
permit. Please note that the dr iv ing
wheels can spin and the vehicle can break a w ay in ESC sport mode, especia lly when
the road is slippe ry.
(D Tips
If the re are faults in the rea r spo ile r sys­
tem or in Audi magnet ic r ide, it may not be
possible to a ct ivate ESC spor t mode or
normal m ode may a ct ivate aga in a utomat­
ically.
Rear spoiler
A ppl ies to vehicles: with ret ractab le rear spoil er
The rear spoiler improves vehicle handling
and enhances driver control.
F ig. 124 Sw itch fo r rear spo ile r
The rear spoi le r deploys and retracts . Spoiler
operation can be set for a utomatic or man ua l
operation.
Automatic mode (normal operation )
-Automatic deployme nt: At a speed of about
75 mph (120 km/h), t he rear spo ile r deploys
automatically.
- Au tomatic retraction: When speed drops be­
low about SO mph (80 km/h), the rear spoil­
er retracts automat ica lly.
Manual mode
- Manual deployment: Tapp ing briefly on the
sw itch
¢fig. 124 deploys the rear spoiler.
- Manual retraction: At sp eeds up to about
10 mph ( 20 km/h), retract the rear spoiler
by pressing a nd ho ldi ng the sw itch
¢ fig . 124. At speeds be twee n 10 mph ( 20
km/h) a nd 75 mph ( 120 km/h), retract the
rear spoi ler by tapping on the switch
¢fig. 124.
A WARNING
-
Driving at higher speeds witho ut the rear
spoiler deployed ca n impair handling char­
acter istics, making the vehicle harder to
control.
- Always ma ke sure that the spo ile r is de­
p loyed when driving at speeds over
85 mph (140 km/h) .
If the rear spoiler
war ning/ indicato r light in the inst ru­
men t clu ster comes on, the rear sp oiler
may not have deployed.
- N ever d rive a t speeds h igher than
85 mph (140 km/h) i f the spoiler is no t
deploye d. Have the spoiler inspected as
soon as possible by an a uthorized Audi
deale r or q ualified workshop.
- Always obey speed limits and othe r tra f­
fic laws .
A WARNING
-Improper operation of the rear spoi ler can
cause crushing injuries.
- Always make sure that nobody, especially
chi ldren, is in t he way when the rear
spoiler is deployed or retracted.

(D Note
Never push the vehicle or apply force to
the rear spoiler -it could be damaged.
@ Tips
Clean the spoiler compartment every 2 to
3 months . The spoiler compartment must
always be free of ice, snow, leaves or other
debris.
Braking
General information
What affects braking efficiency?
Oper ating condit ions and d riving hab it s
T he brakes on today's automobi les are st ill
s ubject to wear, depending largely on opera t­
ing conditions and dr iv ing habi ts
c> & . On
vehicles that are e ither driven mostly in stop ­
and-go city traffic or are d riven hard , the
b rake pads should be checked by you r author­
i zed Audi dealer more often than specified i n
the
Warr ant y & Maint enan ce booklet . Failure
to have your brake pads inspected can res ult
in red uced brake performance.
On steep slopes, you shou ld use the brak ing
effect of the eng ine. This way, you p revent un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not hold the brakes
down continuously. Pump th e brakes at inter­
vals.
Noises may occur when braking d epending on
the speed, braki ng force and outside condi­
tions such as temperature and humidity.
Moistu re or road salt
Unde r certain conditions, for example, w hen
driving through water or ve ry heavy rain, or
even after washing your vehicle, the braking
effect can be reduced d ue to moisture (or in
fre ezing conditions ice) on the brake pads . A
few ca utious brake applicat ions should dry off
the b rake pads or remove any ice coatings.
The effectiveness of the brakes can be reduced
when th e vehicle is driven on a salt-covered
Int ellig ent technolog y 145
road and the b rakes are no t used. Likewise ,
you clean off accumulated salt coating from brake d iscs and pads with a few cautious ap ­
plications of the brake
c> & .
Cor ro sion
T here may be a tendency for dir t to build up
on the brake pads and corrosion to form on
the discs if the car is not driven regu larly or
on ly fo r short trips with litt le use of the
brakes.
If the brakes are not used frequently, or if cor­
rosion has formed on the discs, it is advisable
to clean off the pads and discs by braking
firmly a few times from a moderately high
speed
c> & .
Faults in the brak e syst em
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
c ircuits may have fai led
c> & .
Low brake fluid lev el
Malfunctions can occur in the brake system if
the b rake fluid level is too low. The brake fluid
level is monitored electronica lly.
Brake booster
T he brake booster inc reases the pressure that
you generate with the brake peda l. It works
o nl y when the engine is running
.c> &
Brake lining wear 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 t his in­
spection

aware of when changing a tire? .
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 descend ing a steep grade, reduce
speed and sh ift transmission into a lower

gear or lower driving range. Do no t ride
t h e brakes or hold the pedal down too
long or too often. This cou ld cause the
bra kes to get hot and dimin ish braking
efficiency .
- Do no t "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Th is may cause the brakes to
overheat, prematu re wear and inc reased
stopp ing distan ce.
- Under certain climat ic and operating
c ondit ions such as passing through wa­
ter, driving i n heavy ra in or after wash ing
the vehicle, the effect iveness of the
brakes can be red uced . In winter, ice can
accumulate on the brake pads, linings,
discs and d rums . Carefully apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driving for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake d iscs and pads w it h a few cautious
brake appli cat ions.
- If you damage the fro nt spo iler, or if you
ins tall a different spoiler, be su re the air
flow to the fron t bra kes is not o bstr uct­
ed. O therwise the brake system co uld
overheat reducing the effectiveness of
the entire brake system.
- F ailure o f one bra ke c ircuit will impair
the b raking capability resulting in an in­
creased stopp ing distance . Avoid driv ing
the vehicle and have it towed to the near­
est Aud i dea le r o r qualified workshop.
- Never let the vehicle ro ll to a stop w ith
the engine shut off.
- If the brake booster is not working, t he
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance . Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering .
The degree of power assi st is electronically
matched to vehicle speed .
T he power steering system assists the driver
so that he can steer the vehicle with reduced
physical effor t.
Power steering will not work if t he engine is
off . As a result, the steering wheel will be hard
to turn.
A WARNING
If the system develops a problem , you
must seek qualified profess iona l assis ­
tance .
(D Note
-
If there is an e lectronic malfunction, ser­
votronic
will still function like a conven­
tiona l power steering system, providing a
constant steering support force that is no
l onge r proportionate to the vehicle speed .
This is most not icea ble whe n tu rni ng the
s tee ring w heel a t low speeds (fo r example
when pa rking), -more effort w ill be re­
q uired than us ua l.
- Be aware o f the diffe rent than usual
steering response and adjust your steer ­
ing force acco rdingly.
- Have the problem checked and set right
by an autho rize d Aud i dealer as soon as
possible.
- If a s teer ing mal func tion occurs, this is
signa led wit h the
,'Zr~ or .• indicato r
lights and a warning tone, see.
(D Tips
- If the powe r stee ring system sho uld fai l,
or if the engine is not ru nning (fo r exam­
ple, whi le being towed), you will still be
able to steer the vehicle. However, more
effort will be required to do so.

tioni ng properly, contact your a uthorized
Audi dealer immediate ly.
Driving with your
quattro
App lies to vehicles: with a ll-wheel drive
With all-wheel drive, all four wheels are driv­
en.
Gene ral inform ati on
With all-wheel drive, power is distributed to
all four wheels. This happens automatically
depending on your dr iving sty le and the road
conditions at the t ime. See a lso
r=;, page 142.
The all-wheel drive concept is designed for
h igh engine power. Your vehicle is exception­
ally powerful and has excellent dr iving charac­
ter istics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions
c::;, ,&. .
Winter t ire s
When drivi ng in the w inter, your ve hicle w ith
all-wheel drive has an advantage, even with
regular t ires. In winter road conditions it may
be adv isable to mount winter t ires (or all-sea­
son t ires) for improved driveability and brak­
ing: these tires must be mounted on
a ll f our
w heel s.
See also c::;, page 196, Winter tires.
Snow chains
Where t ire cha ins are mandatory on certain
roads, th is normally a lso applies to vehicles
w ith a ll-wheel d rive
c::;, page 19 7, Snow
chains .
Replacing wheels /tire s
Vehicles w ith all-wheel drive must always
have tires of the same size. Also avoid t i res
with d iffe ren t tread depths. For details see
page
c::;, page 192 , New tires and replacing
tires and wheels.
Off-Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road veh icle.
It is
Int ellig ent technolog y 147
therefore best to avoid rough tracks and un ­
even terrain as much as possib le . Also refer to
r=;, page 151.
_& WARNING
Always adjust your dr iv ing to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks .
- Although the all-wheel drive is very ef­
fective, always remember that braking
capacity is lim ited by tire tract ion. You
should t herefore not d rive at excessive
speeds on icy or slippe ry road s urfaces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
could begin to slide on top of the water
(aquaplaning) . If th is should occur, yo u
wi ll have no warning from a s udden in ­
crease in engine speed as with a front­
wheel drive veh icle. Always drive at
speeds which are su ited to the road con­
ditions. -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting
the engine.
If a vehicle with a conventiona l energy system
is not d rive n for a long per iod of t ime, the bat­
te ry is discharged by idling current consumers
(e.g . immobilizer). In certain circumstances it
can res ult in there being insufficient energy
available to start the eng ine.
Intellige nt energy managemen t in your vehi­
cle handles the dis tribution o f electrica l ene r­
gy. Starting ability is marked ly improved and
the life of the battery is extended .
Bas ica lly, energy managemen t consis ts of

156 Vehicle care and cleaning
_& WARNING
- Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk
of accidents.
- To reduce the risk of cuts, protect your­
self from sharp metal components when
washing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef­
fect may be delayed due to moisture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applications .
@ Note
- If you wash the vehicle in an automatic
car wash, you must fold the exterior mir­
rors in to reduce the risk of damage to
the mirrors. Power folding exterior mir­ rors* must only be folded in and out us­
ing the power folding function.
- To prevent paint damage, do not wash
the vehicle in direct sunlight.
- To reduce the risk of damage, do not
wash the power top with a pressure
washer. -
To reduce the risk of damage, do not
wash decorative decals* with a pressure
washer.
- To reduc e the risk of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:
- To reduce the risk of damage to the
surface, do not use polishing agents or
hard wax.
- Never use car wash cycles that apply
protective wax.
It can destroy the
matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte finish paint. The paint could be
damaged when the stickers or magnets
are removed.
@ For the sake of the environment
Only wash the vehicle in facilities specially
designed for that purpose. This will reduce
the risk of dirty water contaminated with
oil from entering the sewer system.

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tively small patch of rubber on each tire that
assures that a ll- important contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry more weight than they can safely han­
d le, avoiding damage from road hazards and
r eg ularly inspect ing t ires for damage i nclud­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separat ion and blowouts.
A vo idin g damage
If you have to drive over a curb or similar ob­
stacle, drive very slow ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chemicals includ ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
i nstall them .
When removed, the wheels or t ires should be
sto red in a cool, dry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims .
Tires an d wheel s 181
New tires
New ti res have to be broken in¢& .
The tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
patte rn.
H idden damage
Damage to tires and r ims is often not readily
visible . If you notice unusual v ib rat ion or the
vehicle pulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
ti res m ust be chec ked immed iate ly by an au­
thorized Audi dea le r or q ua lified wor kshop .
Unidirectional tires
A un idirectional tire can be identified by ar­
rows on the sidewa ll, that po int in the direc­
tion the t ire is designed to rotate. You must
f ol low the specified di rection of rotation . T his
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.
For more information
¢ page 212.
A WARNING
New tires or t ires that are o ld, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in. To reduce the r isk of losing
control, a co llision and ser ious personal
in ju ries, d rive with special ca re for the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail­
ure, including a blowout and sudden de­
fl ation, cras hes and se riou s personal in­
juries . Have worn or damaged t ires re­
placed immediate ly.
- Tires age even if they are not being used
and can fai l sudden ly, especially at hig h
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at low
speed.

182 Tire s and wheel s
-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.
