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
w heels can spin and the vehicle can break
away in ESC sport mode, especia lly when
t he road is slippery.
(D Tips
If the re a re faults in the rear spo iler sys­
tem or in Audi magnet ic r ide, it may not be
possible to act ivate ESC sport mode o r
normal mode may act ivate aga in a utoma t­
ically.
Rear spoiler
Appl ies to vehicles: with retractable rear spoiler
The rear spoiler improves vehicle handling
and enhances driver control.
Fig. 122 Switch for rear spo ile r
Intelligen t technolog y 143
The rear spoi ler deploys and retracts . Spoiler
operation can be set for automatic or man ual
operation.
Aut omatic mode (normal ope ration )
- Automatic deployment : At a speed of about
75 mph (120 km/h), the rea r spo ile r deploys
automatically .
- Au tomatic retraction: When speed drops be­
low about SO mph (80 km/h), the rear spoil­
er retracts a utomatica lly.
Manual mode
- Man ual deployment : T app ing br iefly on the
sw itch
¢ fig . 122 deploys the rear spoiler.
- Manual retraction : At speeds up to about
10 mph (20 km/h), retract the rear spoiler
by pressing and holding the sw itch
¢ fig. 122. At speeds between 10 mph (20
km/h) and 75 mph (120 km/h), retract the
rear spoi ler by tapping on the switch
¢ fig. 122 .
A WARNING
-
Driving at higher speeds without the rear
spoiler deployed can impair handling char­
acter istics, making the vehicle harder to
control.
- Always make su re that the spo ile r is de­
ployed when driving at speeds over
85 mph (140 km/h) . If th e rear spoil er
warn ing/ indicator light in the inst ru­
men t cluster comes on, the rear spoiler
may not have deployed.
- Never d rive a t speeds higher than
85 mph (140 km/h) i f th e spoiler is not
deployed . Have the spoiler inspected as
soon as possible by an authorized Audi
dea ler or qualified workshop.
- A lways obey speed limits and other traf­
fic laws .
A WARNING
Improper operation of the rear spoi ler can
cause crushing injuries .
- Always make sure that nobody, especially
children, is in the way when the rear
spoiler is dep loyed or retracted.

144 Intelligent technology
-Never push the ve hicle or app ly force to
the rea r spo ile r - i t co uld be damaged .
- To prevent damage to the rear spoiler do
not lean o r place a nyth ing o n it.
- Only ope rate the rear spoi ler manually
when the rear lid is closed and t he rear
spo ile r moving parts are not blocked.
Otherwise, damage could occur.
C lean the spoi le r 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?
Operating conditions and d riving habit s
The brakes on today's automob iles are st ill
subject to wea r, depend ing largely on operat­
i ng cond itions and dr iv ing habits
c:> & . On
ve hicles that a re e ithe r dr iven mostly in stop­
and-go city traffic o r a re driven ha rd , the
b rake pads should be checked by yo ur auth or­
iz ed A udi dealer more often th an specifie d in
the
Warranty & Maintenance booklet . Fail ure
to have your b ra ke pads inspected can res ult
in red uced b rake performance.
O n steep slopes, yo u sh ou ld use t he b ra ki ng
effect of the engine . This way, yo u preven t un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not ho ld the bra kes
down continuously . P u mp the brakes at inter­
va ls.
N oises may occur w hen braking depending on
the speed, bra king force and outside condi ­
tions s uch as temperature and h umidity.
Moisture or road salt
Unde r cert a in co ndi tions, for examp le, w hen
d riving through wate r or ve ry heavy rain , or
even after washing yo ur vehicle , the braking effect can be
reduced due to mois ture (or in
freez ing cond itions ice) on the brake pads. A
f ew cautio us brake applications s hou ld dry off
the brake pads or remove any ice coatings.
T he effec tiveness of the brakes can be red uce d
whe n the vehicle is d riven on a sa lt -covered
road and the b rakes are not used . Likewise,
yo u clean off acc umulated salt coat ing from
brake d iscs and pads with a few cautio us ap­
plicat ions o f th e b rake
c:> & .
Corrosion
The re may be a tendency for dirt to build up
on the brake pads and corros ion to form on
t h e d iscs if the car is not driven regu larly or
o n ly for short trips w ith litt le use of the
brakes .
If the brakes are not used frequently, or if cor­
ros ion has formed on the discs, it is adv isable
to clean off t he pads a nd d iscs by braking
firmly a few times from a moderately h igh
s p eed
c:> & .
Faults in the brake system
If you shou ld notice a sudden increase i n
brake pedal trave l, then one of the two brake
c ircuits may have fa iled
c:> & .
Low brake fluid level
Malfunctions ca n occ ur in the bra ke system if
t h e b rake fluid level is too low. The brake flu id
level is monitored electronica lly.
Brake booster
T he br ake boos ter inc reases the pressure tha t
yo u genera te with the b ra ke peda l. It works
o nl y when t he engine is runnin g
.c:> .&
Brake lining wear status
Br ake lining wear may be che cked by visual in­
spe ct io n of th e condition o f the br ake pa ds
t h ro ugh the open ing s in the wheel. If neces ­
sa ry, the w heel may be removed fo r thi s i n­
spect ion
c:> page 208, What should I be
aware of when changing a tire?.

A WARNING
-You should perform brak ing maneuvers
for the purpose of cleaning the brake
system only if road cond it ions permit .
Other road users must not be put at r isk -
yo u may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transm iss ion into a lowe r
gear or lowe r 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 b rakes" by resting your
foot on the pedal when yo u do not intend
to brake . Th is may cause the brakes to
overheat, premature wear and increased
stopp ing distance.
- Under certain climat ic and operating
condit ions such as passing throug h wa­
ter, driving in heavy rai n or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, lini ngs,
discs and d rums. Carefully apply brakes
f or a test . B rakes wi ll dry and ice coat­
ings wi ll be cleaned
off after a few ca re ­
ful brake applications.
- Driv ing for an ex tended pe riod of time on
salt -covered roa ds without using your
brakes can also affect braking efficiency.
Clean
off accumulated salt coating from
brake discs and pads with a few cautious
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 eff ectiveness of
the ent ire brake system.
- Failure of one bra ke c ircuit will impair
the brak ing capability resulting in an in­
cr eased stopp ing distan ce. Avoid dr iv ing
the ve hicle and have it towed to the near­
est Aud i dea le r or q ualified workshop .
- Never le t the vehicle ro ll to a stop w ith
the engine shu t off.
Int ellig ent technolog y 145
-If the brake booster is not working, the
brake peda l must be pressed considera­
bly harder to make up for the lack of
booster assistance.
Electro-mechanical
power assist
The ele ctro-mechanical power assist helps
the driver when steering .
The degree of power assist is electronically
matched to veh icle speed.
The powe r steering system assists the driver
so that he can steer the vehicle with reduced
physical effort.
Power steer ing will not work if the 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 professiona l assis­
tance.
(D Note
-
If there is an electronic malfunction, ser­
votronic
will still function like a conven­
tiona l powe r steering system, providing a
constant steering support force tha t is no
l onger proportionate to the vehicle speed.
This is most noticeable when t urning the
steering wheel at low speeds (for example
when parking), - more effort w ill be re­
quired than usual.
- Be aware of the different than usual
steering response and adjust your steer­
ing force accordingly.
- Have the problem checked and set right
by an authori zed Aud i dea ler as soon as
possible.
- If a steering malfunction occurs, th is is
signa led w ith the
ls4 or .• indicator
lights and a warn ing tone, see. •
•

146 Intellig ent technolog y
-If the power steering system should fail,
or if the eng ine is not running (for exam­
ple, while being towed), yo u wi ll st ill be
able to steer the veh icle. However, more
effort will be requ ired to do so .
- If the power steering system is not func­
tioning properly, contact your authorized
Audi dealer immediately .
Driving with your
quattro
App lies to vehicles: with all-wheel drive
With all-wheel drive, all four wheels are driv­
en.
General information
W ith all-whee l drive , power is distributed to
a ll four wheels . This happens automa tica lly
depending on your dr iv ing sty le and the road
conditions at the time. See also ~
page 141.
The all-wheel drive concept is designed for
high engine powe r. You r vehicle is exception­
ally powerful and has ex ce ll ent dr iving charac ­
teristics bot h under normal driving conditions
and on snow and ice. Always read and fo llow
safety precautions ¢
.&..
Winter ti re s
When dr iving in the w inte r, your ve hicle w ith
a ll-wheel d rive has an advantage, even with
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tir es) for improv ed driveability and brak­
ing: these tires must be mounted on
a ll fo ur
wheels . See also ¢ page 195, Win ter tires.
Snow cha in s
Where tire chains are mandatory on certain roads, this normally a lso applies to vehicles
with a ll-wheel drive¢
page 196, Snow
chains.
Replacing whe els /t ires
Vehicles wit h all-wheel drive mus t always
have tires of the same size . Also avoid tires
with different tread depths. For details see page
q page 191, New tires and replacing
tires and wheels .
Off-Road driving ?
Your Aud i does no t have enough g round clear­
ance to be used as an off-road vehicle. It is
therefore bes t to avoid rough tracks and un­
even terrain as much as possib le . Also refer to
¢ page 150 .
A WARNING
-Always ad just your dr iv ing to road and traf-
f ic 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 t raction . You
should therefore not d rive at excessive
speeds on icy or slippe ry road surfaces.
- On wet road surfaces, be careful not to
d rive too fast because the front whee ls
could begin to slide o n top of the water
(aquaplan ing). If th is should occur, yo u
will have no warning from a s udden in ­
crease in eng ine speed as wit h a front ­
wheel drive vehicle. Always drive at
speeds which are su ited to the road con­
d itions. -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 conventional energy system
is not driven for a long per iod of t ime, the bat­
te ry is discharged by idling cur rent consume rs
(e .g. immobili zer) . In cert ain circumstances it
can resu lt in the re being insufficient energy
available to start the eng ine.
Intelligent energy management in you r vehi­
cle h andles the dis trib ution of e lectr ica l ene r­
gy. Start ing ability is ma rkedly improved and
the life of the battery is extended . .,._

Basically, energy management consists of
batter y di agno sis, idling cur rent man age­
ment
and d yn ami c en ergy m anagement.
Battery diagnosis
Battery d iagnosis continuously dete rmines
the state of the battery. Senso rs determ ine
battery vo ltage, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling curre nt management
Idling c urrent management red uces energy
consumption while the vehicle is standing.
With the ignition switched off, it contro ls the
energy supply to the various electrica l compo­
nents . Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individua l consumers are grad ually turned off
to prevent excess ive d ischarge of the battery
and thus mainta in start ing capability.
Dynam ic energ y manag em ent
While the vehicle is being driven, dynamic en ­
ergy management distributes the energy gen­
erated according to the needs of the individu­
a l components. It regu lates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge for the battery .
(D Tips
-But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are l imited.
- If starting ab ility is threatened, you are
i nformed by a warn ing
c!;> page 148,
Driver notification in the instrument
cluster display.
Int ellig ent technolog y 147
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driv ing, in city traff ic and during the cold time
of year . Abundant electrical energy is re ­
quired, but only a l ittle is generated .
It is also
c ritical if the engi ne is not running and electri­
ca l components are turned on . In this in­
stance ene rgy is be ing consumed but none is
being generated.
It i s in precise ly these situations that you will
notice ene rgy management act ive ly regu lat­
ing the d istribu tion of ene rgy.
V ehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks , e lectr ica l compo­
nents a re g radually cut back or switched off.
T his reduces energy consumption and ma in­
ta ins s tart ing capability over a longer pe riod .
Take into considerat ion that when you unlock
you r vehicle, some convenience functions,
s u ch as the remo te key o r power seat adjust­
ment, may not be available. The convenience
f unct ions wi ll be available again when you
turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for examp le, w ith
the engine tu rned o ff, the battery is being dis ­
charged .
If starting capabi lity is jeopardized due to en­
ergy consumption , a message appears in the
driver in formation d isplay.
You have to start t he engine to charge the
battery.
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be­ come discharged . This happens mostly when
little energy is being gene rated and a great
deal consumed and the battery's state of
c h arge is not opt imal.
•
•

148 Intelligent technology
To bring the energy balance back into equili­brium, consumers which require especia lly
l arge amo unts of energy are temporari ly c ut
back or switched off. Heating systems in par­
ticular requ ire a great dea l of energy. If you
n otice, for example, that the heated seats * or
the heated rea r window a re not heating, they
have been temporar ily cut back o r switched
off. These sys tems will be ava ilable again as
soon as the energy ba lance has bee n restored.
You will also not ice that engine idle speed has
been inc reased slightly. This is no rma l and not
a cause fo r concern . By increas ing engine idle
spee d the add itiona l ene rgy required is gener ­
ated and the ba ttery 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, th is
i s shown in the instrument cluster display
with the following driver message:
(•) Low battery charge : battery will be
cha rged while dri ving
This notification reminds you that the starti ng
capability of the engine may be limited. As
soon as you start driving aga in, the battery
will be recharged and the notification will go
out .
Driv er notificat ion appears and goes out
again
If t his driver notification appears after the ig­
ni tion is turned on or while driv ing and it goes
out again after a while, the battery has been
adequately rec harged.
Driver notification appears and does not
go out again
If t his driver notification appears after the ig­
n ition is turn ed on or while driv ing and does
n ot go ou t aga in, t he battery's s tate of charge
is not i n the opt imal range. St arting ability is
restricte d. Have the bat tery checked as soon
as possible by a n authorized Audi dealer or
q ua lified workshop.

Driving and
environment
The first 1
1000
miles
(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the first 600 mile s (1,000
kilometre s):
.,. Do not use full throttle .
.,. Do not drive at engine speeds that are more
than 2/3 of the max imimum permitted
RPM .
.,. Avoid high engine speeds.
From 600 to 1,000 miles (1 ,000 to
1,500 kilometres):
.. Speeds can gradually be increased to the
maximum pe rm iss ib le road or eng ine speed .
During and after break-in period
.. Do not rev the engine up to high speeds
when it is cold . T hi s applies whether the
transmission is in N (Neutral) o r in gear.
After the break- in period
.. Do not exceed max imum eng ine speed un­
der any circumstances .
.. Upshift into the next hig her gear
before
reaching the red area at the end of the tach­
ometer scale
<::;> page 10.
During the first few hours of driving, the en­
g ine 's inter na l friction is higher than later
when all the moving pa rts have been broken
i n. How well this break-in p rocess is done de­
pends to a considerable ex tent on the way t he
ve hicl e is driven d uring the first 1,000 miles
(1, 500 kilome tres) .
(D Note
Extremely high engine speeds a re auto­
mat ic al ly reduced. However, t hese RPM-

limits were programmed for an eng ine
well run-in, not a new eng ine.
@ For the sake of the environment
Do not d rive wi th unnecessar ily h igh en­
gine speeds -upshifting ear ly saves f uel,
r educes noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
particularly carefu l for the first 350 miles
(500 ki lometres) after fitting .
A WARNING
-New tires tend to be s lippery and must a l-
so be "b roken-in". Be s ure to remembe r
this dur ing t he firs t 35 0 m iles (500 kilo­
me tres) . Brake gent ly . Avo id following
closely behind other vehicles or other sit­ uations that m ight require sudden, hard
b raking.
New brake pads
Remember that new brake pads do not have a
full brak ing effect during the first 250 miles
(400 kilometres) after they are installed.
New brake pads have to be "burnished in" be­
fore they have optima l grab¢ .&..
D uring the break-in period, yo u should avoid
putting seve re loads on the brakes . Severe
l oads include, for example, su dden hard brak­
ing, in particular at very h igh speeds or, for
example, on mou nta in passes.
A WARNING
Until t hey develop the maximum "bite" fo r
best stopping power, the s urfaces on new
b rake pads requ ire some "brea king- in" dur­
in g the initial 10 0 to 150 miles (15 0 to
20 0 kilome tres) of normal c ity dr iv ing. Yo u
can compensate for this by press ing the
b rake peda l more f irm ly . This applies
whenever new pads are installed.

150 Driving and en vironm ent
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc ., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low­
slung chassis (sports chassis) and fully loaded
vehicles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any highe r tha n the
bottom of the vehi cle body.
- Do no t drive faster than wa lking speed.
_& WARNING
After d riving through water, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake ro tors and pads . Dry
the brakes fi rst by braking carefully to re­
store the full braking effect.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine
off when driving
through water.
- Keep in mind that oncoming vehicles may c reate waves that raise the water
l evel and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh salt water because
it can ca use corrosion.
-
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
.. Always use lead-free gasoline¢ page 160,
Fuel supply .
.. Never run the tank down all the way to emp­
ty.
.. Never put too much moto r o il in yo ur eng ine
¢ page 169, Adding engine oil ~-
.. Never try to push- or tow-st art you r vehicle.
The catalytic co nverter is an efficient "clean­
u p" dev ice built into the exhaust system of
t h e vehi cle. The cata lytic conve rter bu rns
many of the pollutan ts in the exha ust gas be ­
f ore they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critically
impor tant for the life of the catalyt ic convert­
er and prope r funct ion ing of the engi ne.
A WARNING
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry g rass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
r u stproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converte r.
- Do not exceed the correct engi ne oil level
¢page 169.
-Do not drive until the fuel tank becomes
completely empty . The engine co uld mis-
fire. Unburned fuel could also get into ..,.
