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
facture rs fo r the express p urpose o f capturing
data for retrieval after an accident or cras h
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.
A lthough yo ur vehicle is not equ ipped wit h an
EDR, it is equipped with a number of elect ron­
ic control modules for various v ehicl e systems
such as, for examp le, eng ine function, emis­
sion control, as well as for the airbags and
sa fety belts .
These electron ic co ntrol modules also record
vehicle-re lated data du ring norma l vehicle op­
er ation for diagno stic and repa ir purposes .
T he recording capacity of the elec tronic con­
trol modules is limited to data (no sound is re ­
corded) and only a small amount of data is ac­
tually recorded ove r a ve ry limited pe riod of
time and stored when a system fault or other condition is sensed by a cont ro l u nit. Some of
the data t hen stored may re late to vehicle
speed, direction, braking as we ll as restraint
syst em use and performanc e in the event of a
c rash or other condition. Stored data can only
be read and downloaded w ith special equip­
ment .
Electronic Stabilization
Program (ESP)
The Electronic Stabilization Program increas­
es driving stability .
Fig . 1 33 Ce nt er conso le wi th~ bu tto n
Intent and purpose
T he Anti-Lock Brake System (ABS), Elec tronic
D ifferential Lock (EDL) a nd Anti-Slip Regula ­
tion System (ASR) are integrated i n the Elec­
tronic Stabilization Program (ES P).
It increas ­
es control over the vehicle in handling condi­
tions close to the limit of "grip", such as when
acce lerat ing and cornering .
It reduces the r isk
of skidd ing under all road conditions and at
all speeds and improves vehicle stability .
When road condit ions are poor, ES P makes it
easier to start from a complete stop as well as
acce le rate a nd d rive up hills . E S P s witches o n
automatica lly when you start the engine. It
shou ld normally be activated at a ll t imes be ­
cause this ensures optimum veh icle stability .
Critical driving situations
Wi th an oversteering vehi cle ( the vehicle
tu rns too sharply and the rear wheels slide to­
ward the o utside of a cu rve), ESP primari ly
brakes the o utside front wheel, with an
un­
dersteering vehicle (the vehicle does not turn
sharp ly enough and pushes out of a curve) it
brakes the inside rear whee l or other addition­
al wheels. This brake inte rvent ion is accompa­
nied by noises .
If the speed of a wheel s lows down too m uch
rela tive to vehicle speed while braking and i t
starts to lock, brake pressure to this whee l is
reduced . This adjustment process can be felt ..,.

as a pulsing motion of the brake pedal, ac­
companied by some noises. In order for ABS
to be able to operate optimally in th is range,
you must keep the brake pedal depressed -
never "pump the brakes" . You should not ex­
pect that braking d istances w ill be
shortened
under all circumstances with ABS . Braking dis­
tance may even be slightly
longer, for exam­
p le on gravel or wi th fresh snow on a slippery
surface .
If a sign ificant
speed differential between the
d rive wheels on one axle is determined (for
examp le, on a su rface that is s lippery
on one
side),
the EDS brakes the spinn ing whee l and
transfers power to the other drive whee ls.
This is done up to a speed of about 60 mph (100 km/h) . Noises from the brake system
signal that whee l spin is being controlled.
I f one whee l spins when starting from a com­
p lete stop because o f a different grip (for ex­
ample , one wheel o n ice), keep your foot
hard
on the accelerator until the veh icle starts to
move.
If the wheels spin , ASR wi ll automatically re­
duce engine torque and match power to road
surface conditions .
Switching on Sport mod e
In specific driving situations (e.g. Launch Con ­
trol), you swi tch ASR and ESP to Sport mode
by pressing the
[!I button once . The indicator
light
11 illuminates and ESP sport -Wa rni ng!
Restric ted stab ility
appears . "Slip" is matched
to the speed. You should do this only if your
driving skill and traffic cond it ions permit .
Switching ASR /ESP off
In certain sit uations (e .g . in deep snow, on a
l oose surface, o r when rocking the vehicle
free), switch ASR and ESP off by pressing the
[ill button for more than 3 seconds. The ind ica­
tor light
I) illuminates and ES P sw itc hed off -
Warning! R estricted stability
appears . You
should do th is only if your driving skill and
traffic cond itions pe rmit .
Int ellig ent technolog y 151
Switching ASR /ESP on
Activate ASR/ ESP by p ressing the [!I button
again. The message
ESP on appears in the d is­
play briefly.
Brake overheating
So that the disc b rake on a b raked wheel does
not overheat, the EDS switches off automati­
ca lly if there is un usua lly severe loa ding at
th is wheel. The vehicle is st ill drivable and has
the same properties as a vehicle wit hout EDS .
As soon as the brake has cooled down, EDS
swi tches on aga in automatically.
A WARNING
- Even ESP, ABS, EDS and ASR cannot over ­
come the laws of physics . You should
keep this in m ind in particular on an icy
or wet road. If the systems intervene,
you shou ld adjust your speed immediate­
ly to road and traff ic conditions . Do not
be tempted by the increased safety pro­
vided to take risks -you risk having an
accident.
- Please keep in mind that the r isk of an
accident is i ncreased by driving too fast,
pa rti cularly in corners and on icy or wet
ro ads, and by drivi ng too close to the ve­
hicle ahead . Even ES P, ABS, E DS and ASR
cannot eliminate the increased risk of
having an accident.
-Apply the throttle ca re fully when accel ­
erating on a consistently s lippery sur­
face, e.g. on ice and snow . The drive
wheels can spin in spite of the EDS and thereby affect vehicle stability -you risk
having an accident .
- Please note that when ASR or ESP/ASR is
deactivated, the drive wheels can spin on
icy and slippery roads and the veh icle can
break away -the re is a risk of skidd ing!
(D Tips
- In the event of a defect in the rear spoil-
er system or in Audi magnet ic ride, it can
happen that ASR and ASR/ESP cannot be .,.

Braking
New brake pads
During the firs t 250 miles (4 00 km), new
b rake pads do not possess their f ull braking
effect, they have to be "broken in" first. The
d istance can be ten times longer in ve hicles
with ceramic brakes *. Yo u can compensate f or
this slightly reduced b rak ing power by push­
in g harder on the b rake pedal. Avoid heavy
br ak ing loads during the b reak -in period.
Operating conditions and driving habits
The brakes on today's automob iles are st ill
subject to wear, depending largely on operat­
ing conditi ons and dr iv ing habits
c:> & . On ve­
hi cles that are either driven mostly in stop­
a n d-go ci ty traffic o r are d riven ha rd, the
b rake pads should be checked by you r auth or­
iz ed A udi dealer more o ften than specifie d in
the
Warranty & Maintenan ce booklet . Fail ure
to have your b rake pads inspected can res ult
i n re duced b rake performance.
O n steep slo pes, you shou ld use the b ra kin g
effec t of the eng ine. Th is w ay, yo u prevent un­
n ecessa ry wea r on the bra ke system . If you
must use yo ur brakes, do not ho ld the bra kes
down continuously. P ump the brakes at inte r­
va ls.
Moisture or road salt
A t speed s above 70 mph ( 110 k m/h) and wit h
the windshield wipe rs swi tched
on (at le ast in ­
terval stage 4), the bra ke pads are br iefly a p­
p lied against the bra ke discs. T his occ urs at
regu lar intervals witho ut the driver noticing
and prov ides for better brake response time

Unde r ce rtain conditions, for examp le, w hen
driving thr ough water or ve ry heavy rain, or
even after was hing yo ur vehicle, the brak ing
effect ca n be red uced d ue to moisture (or in
freezing conditions ice) on the brake pads. A
few ca utious brake applicat ions should d ry off
t he bra ke pads o r rem ove any ice coa tings.
The effective ness of the brakes can be reduced
when the vehicle is dr iven o n a salt-covered

Corrosion
The re may be a tendency for di rt to build up
on the brake pads and cor ros ion to form on
the discs if t he car is not driven regu la rly or
on ly for short trips w ith litt le use of the
brakes.
If the brakes are not use d frequently, o r if cor­
r os ion has formed on the discs, it is adv isa ble
to clean off the pads and d iscs by braking
firmly a few times from a moderately high
speed
c:> & .
Faults in the brake system
If you shou ld not ice a sudden in crease i n

Low brake fluid level
Malfunctions can occ ur in the brake system if
the brake fluid level is too low. The brake flu id
level is monitored elect ro nica lly.
Brake power assist unit
T he bra ke power assist unit increases the
pressure that you generate w ith the brake
pedal. It work s only when the engine is run­
ning.
Brake lining wear status
B ra ke lining wear may be che cke d by visual in ­
s p ection of t he condition of the bra ke pads

154 Intelligent technology
Other road users must not be put at risk -
you may cause an accident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving position . Do not
ride the brakes or hold the pedal down
too long or too often. This could cause
the brakes to get hot and diminish brak­ ing 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
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Cautiously apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few cau­
tious brake applications .
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads with a few cautious
brake applications.
- 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 entire brake system.
- Failure of one brake circuit will impair
braking capability, resulting in increased
stopping distance. Avoid driving the vehi­
cle and have it towed to the nearest au­
thorized Audi dealer or qualified work­
shop.
- 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 brake pedal must be pressed considerably harder to make up
for the lack of booster assistance.
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 vehi­
cle with little physical effort.
If the engine is not running, the power steer­
ing 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 sys­
tem. Turning the steering wheel fully to the left or right will 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 damage to the power steering system .
(D Tips
-In the event of a power steering system
failure, or if the engine is not running
(while being towed), you will still be able
to steer the vehicle. However, you will re­
quire 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
special hydraulic fluid. The power steer­
ing fluid reservoir is located in the en­
gine compartment. The correct hydraulic
fluid level is important for proper opera­
tion of the power steering system. The
power steering fluid level is checked ac­
cording to the Audi maintenance service
schedule.

158 Driving and en vi ro nm ent
Driving and
environment
Break-in period
A new vehicle must be broken in, and the break-in per iod should 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 eng ine speed of 6,000 rpm You
must also not use fu ll acce lerat ion between
600 and 1,200 mi les (1,000 to 2,000 km).
F rom 1,200 to 1,500 mi les (2,000 to 2,500
km), you can gradua lly increase maxim um en­
gine speed to 8,250 rpm for brief periods.
During the first ho urs of operation, there is
g reater friction in the engine and the trans­
mission than later when a ll the moving parts
have broken in.
The way yo u drive duri ng the first 1,500 miles
(2,500 km) affects engine quality. If you drive
at moderate engine speeds thereafter, partic ­
u lar ly when the engine is cold, yo u reduce en ­
g ine wear and increase the potential mileage
of the engine.
Do not drive at RPMs that are too low. Shift
down when the engine is no longer running
"smoothly". Extreme ly high RPMs are gov­
erned automatically.
Driving through water
on roads
Note the following to avoid vehicle damage
when dr iving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body .
- Do not drive faster than wa lking speed.
.&_ WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet b rake roto rs and pads. Dry
t he brakes fi rst by bra king carefully to re­
sto re the full braking effect.
-
(D Note
Vehicle components such as the eng ine,
transmission, suspension or e lectrical sys­
tem can be severe ly damaged by dr iv ing
through water.
@ Tips
- Check the depth of the water before d riv­
ing through it.
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely .
- Avo id driving through salt water because
it can cause corros ion.
Catalytic converter
You must use lead-free gasoline in your veh i­
cle, otherwise you will destroy the catalyt ic
converter.
Never run the fuel tank completely dry; their­
regular fuel supply could cause misfires . This
allows unburned fuel into the exhaust system,
poss ibly resulting in overheating and damage
to the catalytic converter .
.&_ WARNING ,-
-Do not park or operate the vehicle in
areas where the hot exha ust system may
come in co nta ct with dry g rass, brush,
fue l spills or o ther material which can
cause a fire.
- Do not app ly addition al under coating or
r u stproofing on or nea r the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
To ensure efficient o peration of the Emis­
s ion Control System:

-Have you r vehicle maintained properly
and in accordance with the service rec­
ommendat ions in your Warranty
& Main­
tenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the Emission Control Sys­
tem and could lead to damage.
Sporty driving
Warming up and cooling down
By carefully warming up and cooling down
your vehicle, you can he lp ensure that it is not
overstressed unnecessarily during sporty driv ­
ing.
When warming up, the vehicle is driven at a maximum engine speed of
6000 RPM
(Vl0 engine) or 7000 RPM (V8 engine) in or­
der to raise the engine oil temperature to a minimum of
140 °F (60 °(). The tires also on­
ly reach their full road holding capability once
they have warmed up .
The cooling fan can continue to run in your ve­ h icle after the engine is switched
off. H owev­
er, driving the vehicle to cool it down is part ic ­
ularly important. During sporty driving, the
engine and brakes, the exhaust system, and
the t ransm ission all become ex treme ly hot.
Before you park the vehicle, you shou ld d rive
it for a few mi les/kilometers at light load in
the low rpm range to allow it to coo l down .
Driving on a track
Before you take your vehicle out on a track,
ensure that it is in perfect condition. For ex­
ample, you should check the tire tread and the brake pads . It is best to increase t ire pressure
by about 0 .3 bar .
When driving on a track, oil consumption may be somewhat higher than in "normal" opera­
tion ¢page
180.
You shou ld definitely inspect your vehicle af­
ter subjecting it to severe condit ions. Are the
brake pads OK? Is there anything unusual
Dri vin g and en vironm ent 159
about the ti res, including the inner and outer
sidewa lls (e.g . tread, blistering)? Are the air
intakes free of leaves and tire dust? Is the o il
l evel OK?
Your authorized Audi dea ler or qua lified work­
shop will be happy to undertake an inspection
before and after use on the race track.
(D Tips
- Some race tracks (e.g . steeply banked
t u rns) may affect the response of the
ESP .
- When driven on a race track, all vehicle
parts are severe ly stressed. This can re ­
sult in increased wear.
Operation and maintenance
Fuel economy, env ironme nta l impact, and
wear on your eng ine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
By having your ve hicle reg ularly se rv iced by an
authorized Aud i dea ler helps to ens ure that i t
r uns properly and econom ica lly. The condition
of your veh icle not only affects its safety and
ability to ho ld its va lue, it a lso affects
f u el
con sumptio n.
The amount o f oi l used is re lated to engine
load and speed .
It is normal fo r the oil consump tion of a new
engine to reac h its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 mi les
(5,000 kilometers) before you can p rope rly
assess oil consumpt ion.
This also app lies to fue l cons umption and en­
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service

for substantiating a warranty cla im should
corrosion damage or paint defects occur.
Your authorized Audi R8 dealer has a variety
of
d edicat ed ve hicl e-car e produ ct s. Please
make sure you apply them correctly .
A WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caution labels .
- Always read directions on the container before using any product. Follow the di­
rect ions carefu lly.
- Most chemical cleaners are concentrated and have to be diluted .
- Use spot removing fluids only in well
ventilated areas .
- Do not use gasoline, kerosene, d iesel
fuel, nail polis h remover or other volatile
fluids . They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wa x or d ry the vehicle wi th the ign it ion
on or the eng ine running.

Select only environmentally friend ly clean­
ing products . Leftover clean ing products
should not disposed of in the household
waste .
Cleaning and protec tion 16 1
Care of exterior
Washing your vehicle
The longer i nsect rema ins, bird dropp ings,
t ree res in , ro ad and indust rial dust, tar , soo t
particles, road salt, and o ther aggressive de­
pos its remain on the vehicle su rface, the more
lasting their destructive effect will be . High
temperatures, for example from intense s un­
light, intensify the corrosive effect.
After the end of winter road salting, the un­ derside of the vehicle shou ld be thoroughly
washed .
Automatic car washes
You must t ake the necessary precautions s uch
as clos ing t he windows and convert ible top
before using an automatic car wash.
If yo ur
vehicle has specia l accessories - e.g . spoilers,
radio antenna -it is best to speak to the oper­
ator of the car wash c:>(D .
Only use car washes where the vehicle re ­
mains stationary and the cleaning equipment
moves around the veh icle while washing and
drying. It is not possib le to use car washes
where the vehicle is moved forward on a con­
veyer
c:> ,& .
It is preferab le to wash your vehicle in a
brush less carwash .
Washing with a pow er wa sher
When was hing yo ur vehicle with a power
washe r, be sure to follow the operating in ­
structions for the power washer. This applies particu larly to the
p ressure and the spra ying
distance .
Mainta in sufficient distance from
soft materials such as rubber hoses, sound
deade ning mater ial, and the park ing aid sen­
sors* that are located i n the front or rear
bumper.
Do not use washers with
a ro tating jet or a
nozzle spraying
a h igh pr essur e je t of wate r in
any case.

162 Cleaning and protection
Hand washing
When washing your vehicle by hand, first soft­
en the dirt with copious amounts of water and
rinse it
off as best you can.
Then clean the vehicle using a soft
sponge, an
auto glove or a low-pressure wash brush.
Work from the top down to the bottom, start­
ing with the convertible top
¢ page 163. Use
a
shampoo only for v ery stubborn dirt.
Rinse the sponge or auto glove thoroughly at
frequent intervals.
Clean the wheels, door sills and similar areas last. Use a separate sponge for this.
_& WARNING
-Car washes with conveyors can damage
the vehicle tires, which could cause the tire to lose pressure suddenly while driv­
ing and put you at risk for an accident.
Do not use car washes with conveyors.
- Switch
off the ignition when you wash
your vehicle to avoid an accident.
- Protect your hands and arms from sharp
metal edges when you clean the under­
body, the inside of the wheel wells or the
wheel covers to avoid cutting yourself.
- When washing your vehicle in the winter :
Moisture and ice in the brake system can
affect the brakes.
- Never wash tires with a jet that sprays
water in a direct stream . This could cause
invisible damage to the tires and weaken
them, even if the spray is from a relative ­
ly long distance and for a short time .
Damaged and weakened tires can fail
and cause accidents and personal injury.
(D Note
- Never drive your vehicle through any au ­
tomatic car wash that fails to provide ei­
ther sufficient clearance for your vehicle
or sufficient track width for your tires. Risk of expensive damage to the vehicle's
underbody , tires, and rims!
- As described in your Warranty
& Mainte­
nance booklet, damage or malfunction due to misuse of the vehicle or failure to
operate the vehicle in accordance with
the
instructions of this Owner's Manual
will not be covered under warranty.
- Fold the exterior mirrors flat - there is a
risk of damaging the exterior mirrors .
Power folding exterior mirrors must not
be folded in or out by hand. Use the pow­
er function!
- Do not wash the vehicle in direct sun­
light. You may damage the paint.
- Do not use sponges designed to remove
insects, rough kitchen sponges, or simi­
lar products. You risk damaging the
paint surface.
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
ing your vehicle. Never clean the head­
lights with a dry cloth or sponge . Use a
wet cloth or sponge .
It is best to use
soapy water.
- Never clean tires using a nozzle that
sprays water in a direct stream. Damage
can occur even with a relatively long
spraying distance and for a very short
time.
- To avoid damaging your vehicle, always
make sure that there is sufficient dis­
tance between the spray head and soft materials like rubber hoses, plastic parts
and sound-deadening materials. Never
aim the spray head at the same point for
a long time. This also applies to cleaning
headlights and painted bumpers. Re­
member: the closer the nozzle is to the
surface of the material, the greater the
stress on the material.
- Never clean the convertible top using a
power washer.
@) For the sake of the environment
Wash your vehicle only at specially de­
signed facilities. They can prevent any dirty
water contaminated by oil from entering
the waste water. In certain areas washing
a car outside of such facilities is not per­
mitted.
