Anti-loc k br aking sy stem (ABS )
ABS prevents the wheels from locking up when
brak ing . T he vehicle can st ill be stee red even dur ­
ing hard braking. App ly steady pressure to the
brake peda l. Do not pump the peda l. A pulsing in
the brake pedal indicates that the system is help­
ing you to brake the vehicle.
Brake assist sy ste m
The brake assist system can decrease braking dis ­
tance. It increases braking power when the dr iver
presses the brake pedal quick ly in emergency sit­
uations. You must press and ho ld the brake pedal
until the situation is over.
Anti -slip regulation (ASR )
ASR reduces engine power when the drive whee ls
begin to spin and adapts the force to the road
conditions. This makes it easier to start, acceler ­
ate and dr ive up h ills.
Electronic diff erential lock (EDL )
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive wheel or wheels if the vehicle is equipped w ith all-whee l
drive*. This function is available up to about 60
mph (100 km/h) .
I n extreme cases , EDL automatically switches off
to help keep the brake on the braked wheel from
overheating . EDL wi ll switch on again automati­
cally when conditions have returned to normal.
A WARNING
- ESC, ABS, ASR and EDL cannot overcome the
laws of phys ics. Th is is especially important
on slippery or wet roads. If the syst ems be­
gin act ing to stab ilize your vehicle, you
sho uld immediately cha nge your speed to
match the roa d and traffic con ditions. Do
not let the increased safety provided by
these systems tempt you to take risks . Do­
ing so wi ll increase the risk of a loss of vehi­
cle contro l, collis ion and serio us personal in­
juries .
- Always adapt your speed to road, traffic and
weather cond it ions. The risk of losing con­
tro l of the veh icle increases when driving
Int ellig ent t echnolo gy
too fast, especially through curves and on
slippery or wet roads, and when dr iving too
close to vehicles up ahead. ESC, ABS, the
brake assist system, EDL and ASR cannot
prevent coll is ions .
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance sys tems that cannot always help to reduce
the risk of loss of veh icle control.
(D Tips
- ABS and ASR only wo rk correctly when all
four wheels are eq uipped with ident ical
tire s. Different tire s izes can lead to a reduc­
t ion i n engine power.
- Yo u may hear noises when the systems de­
sc ribed a re wo rking.
- If the ind icator light GJ or II (USA mod­
els) ;tiJ (Canada models) appea rs, there
may be a malfunction~

Braking
What affects braking efficiency?
New brake pad s
During the f irst 250 miles (400 km), new brake
pads do not possess the ir full braking effect, they
have to be "broken in" first¢.&. . The break- in pe­
riod can be considerab ly longer for vehicles w ith
ceramic b rake roto rs*. You can compensate for
this s light ly reduced b ra ki ng power by push ing
ha rder on the b rake peda l. Avoid heavy braking
loads during the bre ak-in period.
136
Operating conditions and driving habits
The bra kes on today's automobiles a re s till sub­
j ect to wear, depend ing largely on operating con ­
ditions and driving habits ¢& . On vehicles that
a re either driven most ly in stop-and-go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Aud i dealer more of­
te n tha n specified in the Warranty
& Maint e­
nance bookl et. Failure to have you r brake pads
i nspected can resu lt in reduced b rake pe rform­
ance.
On steep slopes, you shou ld use the braking ef­
fect of the engine . This way, you prevent un nec­
essary wear on the brake system . If you must use
you r brakes, do not hold the bra kes down cont in­
u o usly. Pump the brakes at in tervals.
Operating noise
Noises may occur when braki ng depending on the
speed, braking force and outs ide cond it ions such
as tempera ture and hum idity.
Due to the nature of the materia ls used i n ceram­
i c brake rotors*, noises may become more appa­
r ent at low speeds.
Effect of water and road salt
In certa in situations, for examp le after driv ing
through water , in heavy rain, after overnight con­
densation or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads . The brakes must be
dr ied fi rst w ith a few careful b rake app lications.
At higher speeds and with the windsh ield wipers
turned on, the brake pads press against the brake r otors for a short amount of time. This occurs at
r egular intervals without the dr iver not ic ing and
provides fo r be tter brake response time under
wet cond it ions.
The effect iveness of the brakes ca n be red uced
when the v ehicle is d riv en on a salt-cove red road
and the b rakes are no t used. Likewise, you clean
off a ccumula ted salt coating from b rake d iscs
and pads with a few ca utious app lications of the
brake ¢& .
D ue to the ir sur fa ce character istics, cerami c
brake ro tors * absorb moistu re in such co ndi tions . ..,.

This can cause a temporary reduction in braking
force compared to dry brakes. You can compen­
sate for this by pressing the brake pedal harder.
Cor ro sion
There may be a tendency for dirt to bui ld up on
the brake pads and corrosion to fo rm on the discs
if the car is not driven regularly or only for short
trips with little use of the brakes.
If the b rakes are not used frequently, or if corro­
sion has formed on the discs, it is advisab le to
clean off the pads and discs by braking firmly a
few times from a moderately high speed
c:> &. .
Faults in the brake sy stem
If you should notice a sudden increase in brake
pedal travel, then one of the two brake circuits
may have fai led
c:> .&, .
Low brak e flu id le vel
Malfunct ions can occur in the brake system if the
brake fluid level is too low. The brake flu id leve l is
monitored e lectronically.
Br ake power assis t un it
T he brake power assist unit increases the pres­
sure that you generate with the brake pedal.
It
works only when the eng ine is running .
Brak e lining wear sta tu 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 this inspection
c:> page 203 .
.8, WARNING
-New brake pads don't have the best stop­
ping power and must be "broken-in" during
the init ial 250 mi les ( 400 km) of normal city
driving. The break -in period can be consider­
ably longer for vehicles with ceramic brake
rotors *. You can compensate for this by
pressing the brake pedal more firmly. This
also applies later when new pads are instal­
led .
- You should perform brak ing maneuvers for
the purpose of clean ing the brake system
Int elli ge nt te chn olo gy
only if road conditions permit. Other road
users must not be put at r isk -you may
cause an accident!
- Before descending a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride the
brakes or hold the pedal down too long or
too often. This could cause the bra kes to get
hot and dimin ish braking effic iency .
- Do not "ride the brakes" by rest ing your foot
on the pedal when you do not intend to
brake. This may cause the brakes to over­
heat, premat ure wear and increased stop­
ping distance.
- Under certain cl imatic and operat ing condi ­
tions such as passing thro ugh water, dr iv ing
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced . In winter, ice can accumulate on the
brake pads, lin ings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of t ime on
salt-covered roads without using your brakes can also affect braking efficiency .
Clean off accum ulated salt coating from
b rake discs and pads with a few cautious
brake applications.
- If you damage the front spoiler, or if you in­
stall a different spoiler, be su re the air flow
to the front brakes is not obstructed . O ther­
wise the brake system could overheat reduc­
ing the effectiveness of the entire brake sys­
tem .
- Fai lure of one brake circuit will impai r the
braking capability resu lting in an increased
stopping distance . Avoid driving the vehicle
and have it towed to the nearest Aud i dea ler
or qualif ied workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, for ex­
ample when towing your veh icle, or because
the brake booster has somehow been dam­
aged, the brake pedal must be pressed con ­
siderably harder to make up for the lack of booster assistance.

Rear spoiler
The rear spoiler improves vehicle handling and
enhances driver control.
SPORT •
Fig. 127 Switch for rear spoiler
The rear spoiler deploys and retracts. Spo iler op­
eration can be set for automatic or manual oper­
ation.
Automatic mode (normal operation)
-Extending automatically: This occurs when driv­
ing faster than approximately
62 mph (100
km/h) or at a certain engine compartment tem­
perature1l.
- Retracting automatically: This occurs when
driv ing s lower than approximate ly
22 mph (35
km/h) or at a certain engine compartment tem­
perature1l.
Manual mode
- Extending manually: Press the switch
~ fig. 12 7 briefly to extend the rear spoi ler
completely.
- Retracting manually: When dr iving at speeds
below approximately
12 mph (20 km/h), press
and hold the switch to retract the rear spoiler.
When dr iving at speeds between
12 mph and
62 mph (20 km/h and 100 km/h), press the
switch briefly to retract the rear spoiler com­
pletely. You cannot retract the rear spoiler if it
extended due to the engine compartment tem­
perature.
1 > The rear spoiler only extends or retracts above a certain
e ngine temperature in some mode ls.
138
Indicator light
When the indicator light I-· appears, there is a
system malfunction. The rear spoi ler may not be
able to extend. This could change the vehicle's
driving character istics at high speeds. Do not ex­
ceed 87 mph
(140 km/h). Drive to your author­
i zed Audi dealer immediately to have the mal­
function corrected.
A WARNING
-
Driving at h igher speeds without the rear
spoiler deployed can impair handling charac­
ter istics, making the vehicle harder to control.
- Improper operation of the rear spoiler can
cause crushing injuries. A lways make sure
that nobody , especial ly children, is in the
way when the rear spoiler is deployed or re­
tracted.
- Always obey speed limits and other traffic
laws.
- Hot air from the engine compartment can
escape through the rear spoiler when it is
open and it could burn you.
(D Note
-Never push the vehicle or apply force to the
rear spoiler -it could be damaged.
- To prevent damage to the rear spo iler do
not lean or place anything on it.
- Only operate the rear spo iler manually when
the engine compartment lid is closed and
the rear spoiler moving parts are not
bloc ked. Otherwise, damage could occur.
(D Tips
Clean the spoiler compartment every 2 to 3
months. The spoiler compartment must al­
ways be free of ice, snow, leaves or other de­
bris.

Power steering
When the engine is running, power steering
makes i t easier for the driver to steer.
Power steering helps the driver steer the vehicle
with litt le physical effort.
If the engine is not running, the power steering
system is also not working. In this case, you will
find it extremely difficult to turn the steering
wheel.
If you turn the steering fully to the left or right
when the vehicle is stationary, you place a very
heavy load on the power steering system. Turning
the steering wheel fully to the left or right wi ll
cause noise in the system . It also reduces engine
idle speed.
(D Note
Do not hold the steering turned fully to the
left or right for more than 10 seconds when
the engine is running. There is a risk of dam­
age to the power steering system.
@ Tips
- In the event of a power steering system fail­
ure, or if the engine is not running (while
being towed), you will still be able to steer
the vehicle. However, you will require more
effort to do so.
- If the power steering system has a leak or is
defective, you should immediately contact a
qualified workshop .
- The power steering system requires a spe­
cial hydraul ic fluid . The power steering fluid
reservoir is located in the engine compart­
ment. The correct hydraulic fluid level is im­
portant for proper operation of the power
steering system. The power steering fluid
l evel is checked according to the Audi main­
tenance service schedule.
Dry sump lubrication
High lateral and longitudinal forces affect the en­
gine and the vehicle during sporty driving. Dry
sump lubrication ensures that your engine is sup-
Intelligent technology
plied with oil and properly lubricated even under
these conditions.
In a "norma l" vehicle the oil pump sends the oil
from the oil pan to the lubrication points in the
engine . The oil then returns to the oil pan. In ex­
treme situations, the oil pump may draw in air,
wh ich results in insufficient oi l pressure .
With dry sump lubrica tion, the oil is not in the oil
pan (it is "dry"), but in a separate oi l tank. While
one pump supplies the engine with oil, a second
pump suct ions the oil out of the engine and re­
turns it to the o il tank. Because the oil tank is tall
and narrow, oil pressure is constant even under
extreme conditions .
In add ition, the oi l pan in vehicles with dry sump
lubrication is noticeably shallower . This allows
the engine to be installed lower in the vehicle,
bringing down the center of gravity . This im ­
proves your vehicle's handling.
Driving with your quattro
With oil-wheel drive, all four wheels are driven .
General information
With all-wheel drive, power is distributed to all
four wheels . This happens automatically depend­
ing on your driving style and the road conditions
at the time . See also
c:::.> page 134.
The all-whee l drive concept is designed for high
engine power . Your vehicle is exceptionally pow­
erful and has excellent driving characterist ics
both under normal driving conditions and on
snow and ice. Always read and fo llow safety pre­
cautions
c:::.> .&_ .
Winter tires
When driving in the winter, your vehicle with all­
wheel drive has an advantage, even with regular
t ir es . In winter road condit ions it may be advisa­
ble to mount winter tires (or all-season t ires) for
improved driveability and brak ing: these tires
must be mounted on
all four wheels. See also

Intelligent technology
Snow chain s
Where tire cha ins are mandatory on certai n
roads, this normally a lso applies to vehicles with
all-wheel drive
¢ page 194, Snow chains .
Replacing wheels /tires
Vehicles w ith all-whee l drive must a lways have
tires of the same si ze. Also avoid t ires with differ ­
ent tread depths. Fo r deta ils see page
¢ page 186, New tires and replacing tires and
wheels.
Off-Road driving?
Your Audi does not have enough ground clear­
an ce to be used as an off-road veh icle.
It is there ­
fore best to avo id rough tracks and uneven ter­
rain as m uch as possible . A lso re fer to
¢ page 142.
A WARNING
-Always adjust your driving to road and traf­
fic cond itions. Do not let the extra safety af·
forded by all-whee l dr ive tempt you into tak­
ing extra r isks .
- Althoug h the all-wheel dr ive is very effec­
t ive, always remember that brak ing capac ity
is limited by tire tract ion. You should there­
fore not dr ive at excessive speeds on icy o r
slippery road su rfaces.
- On wet road su rfaces, be careful not to drive
too fast because th e front whee ls cou ld be­
gin to slide o n top of the water (aquap lan­
ing).

Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa­
bility of electrical energy for starting the engine.
If a vehicle w it h a conventional energy system is
not drive n for a long per iod of t ime, the battery
is discharged by idli ng cur rent consumers (e.g .
140
immob ili zer). In certain c ircumstances it can re ­
s ul t in the re being insufficient energy available to
start the eng ine.
I ntelligent energy managemen t in your veh icle
hand les the d istribution of electrical energy .
Starting ability is markedly improved and the life
of the battery is extended.
B asically, energy managemen t consis ts of
bat­
tery diagnosi s, idling current management
and
dynamic energy management.
Battery diagnosis
Battery diagnosis continuously dete rm ines t he
st ate of the bat tery. Sensors dete rm ine battery
vo ltage, batte ry cur rent and battery tempera­
ture . This de termines the current state of cha rge
and t he power of the battery.
Idling current management
Idli ng cur ren t management reduces energy con­
sumption whi le the vehicle is s tanding. W it h the
i gni tion swi tched off, it contro ls the energy s up­
ply to the various electrical components . Data
from battery d iagnosis is considered.
Depend ing o n the ba tte ry's st ate of ch arge, indi­
vidual consumers are gradua lly tur ned o ff to pre­
vent excessive discharge of the batte ry and thus
maintain starting capa bility .
Dynamic energy management
While t he ve hicle is being driven, dynamic e ne rgy
m anag eme nt dis trib utes the energy ge nerated
accord ing to the needs of the individ ua l compo ­
nents . It regu lates consumption, so that more
e lectrica l ene rgy is not be ing used than is being
generated and ens ures an optima l state of
c h arge for the battery.
(D Tips
- But even ene rgy management cannot neg­
ate the lim its of physics. Cons ider that the
p ower and life of a batte ry are lim ited.
- If start ing ability is threa tened, you are in ­
formed by a warning ¢

What you should know
The highest priority is given to maintaining start­
ing capability .
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time of
year . Abundant electrical energy is required, but
only a little is generated . It is also critical if the
engine is not running and electrical components
are turned on. In this instance energy is being
consumed but none is being generated.
It is in precisely these situations that you w ill no­
tice energy management actively regulating the
d istribution of ene rgy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of
several days or weeks , electr ical components are
gradually cut back or switched off . This reduces
energy consumption and maintains starting ca­
pability over a longer pe riod .
Take into consideration that when you unlock
your veh icle, some convenience functions, such
as the remote key or power seat adjustment, may
not be available. The convenience functions will
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 example, with the
engine turned off, the battery is being dis­
charged .
If starting capability is jeopardized due to energy
consumption, a message appears in the driver in­
formation display .
You have to start the engine to charge the bat ­
tery .
With the engine running
Although electrical energy is generated when the
vehicle is being driven, the battery can become
discharged. This happens mostly when little en­
ergy is be ing generated and a great deal con­
sumed and the battery's state of charge is not
optimal.
Intelligent technology
To bring the energy balance back into equilibri­
um, consumers which require especially large
amounts of energy are temporar ily cut back or
switched off. Heating systems in part icu lar re­
quire a great deal of energy. If you notice, for ex­
ample, that the heated seats* or the heated rear
window are not heating, they have been tempo­
rarily cut back or switched off . These systems w ill
be available again as soon as the energy balance
has been restored.
You w ill also not ice that engine idle speed has
been increased slightly . This is normal and not a
cause for concern. By incr easing eng ine idle
speed the additional energy required is generated
and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops in to the range where it
can limit the ability of the engine to start, this is
shown in the instrument cluster display w ith the
following driver message :
[•] low battery charge: battery will be charged
while driving
This notification reminds you that the starting
capability of the engine may be limited. As soon
as you start driving again, the battery will be re­
charged and the notificat ion will go out .
Driver notification appears and goes out
again
If this driver notification appears after the igni­
tion is turned on or while driv ing and it goes out
again after a while, the battery has been ade ­
quately recharged .
Driver notification appears and does not go
out again
If this driver notif ication appears after the ign i­
t ion is turned on or while dr iv ing and does not go
out again, the battery's state of charge is not in
t h e optimal range. Starting ability is restricted .
Have the battery checked as soon as possible by
an authorized Audi dea le r or qualified workshop.

Driving and en vironment
Driving and environment
Break-in period
A new vehicle must be broken in, and the break-in
period shou ld be 1 ,500 miles (2,500 km) . Do not
use full acceleration for the first 600 miles
(1 ,000 km) and do not exceed the maximum en­
gine speed of 6,000 rpm You must also not use
full accelerat ion between 600 and 1,200 miles
(1,000 to 2,000 km) . From 1,200 to 1,500 miles
(2 ,000 to 2,500 km), you can gradually increase
maximum eng ine speed to 8,250 rpm for brief
pe riods.
During the first hours of operation, there is
greater fr iction in the eng ine and the transmis­
sion than later when all the moving pa rts have
b roken in .
The way you drive during the first 1,500 miles
(2 ,500 km) affects engine quality . If you drive at
modera te engine speeds thereafter, part icu larly
when the engine is cold, yo u red uce eng ine wea r
and increase the potential mileage o f the engine.
Do not dr ive at RPMs that a re too
low. Shift down
when the engine is no longe r runni ng "smooth­
ly". Extremely high RPMs are gover ned automati­
cally.
Avoid damaging the
vehicle
W hen 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 damaged .
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
d riving through water, for examp le on flooded
roads:
- The water must no t be any h igher than the bot­
tom of the vehicle body.
142
- Do not drive faster than walk ing speed .
A WARNING
After driv ing through water, mud, s lush, etc .,
the brakes may be s low to take effect because
of wet brake rotors and pads. Dry the brakes
first by brak ing carefully to restore the full
braking effect.
(D Note
Vehicle components such as the eng ine,
transmission , suspension or e lectrical system
can be severe ly damaged by dr iv ing t hrough
water .
(D Tips
- Check the dept h of the water before driving
through it.
- Do not stop the vehicle, drive in reverse or switch the engine off when driv ing through
water.
- Keep in mind that oncoming veh icles may
create waves that raise the water level and
make it too deep for your vehicle to d rive
through safely .
- Avoid driving through salt water because it
can cause corrosion.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmen tally sound manner.
.,. Always use lead-free gasoline ~ page 151,
Fuel supply.
.,. Never r un the tank down all the way to empty.
.,. Never put too much mo tor o il in yo ur engi ne
~ page 160, Adding engine oil 'l::r..
.,. Never try to push- or tow-sta rt your vehicle .
The cata lytic converter is an effi cien t "clean -up"
device built in to the exhaust system of the vehi ­
cle. The cata lytic conve rter burns many of the
po llutants in the exhaust gas before they are re­
l eased into the atmosphere.
