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

road and the b ra kes are no t used . Li kewise,
yo u clean off accu mulated salt coatin g from
brake d iscs and pads with a few cautio us ap
plications of t he brake

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

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.

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.
Cleaning and protect ion
General information
Regular core preserves vehicle value.
Regular and correct care will contribute to
maintaini ng the beauty and value of your Au
d i. Furthermore, good care may be a condition
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.
- Do not clean the undersides of chassis,
fenders, wheel covers, e tc. wit h out pro
tecting your hands and arms . You may
c u t yourself on sharp -edged metal parts .
- Moist ure and ice on brakes may imp air
braking efficiency
c:> page 153, Broking.
T est the brakes carefully each time you
wash the vehicle.
@) For the sake of the environment
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
