Cleaning and protect ion
General information
Regular core preserves vehicle value .
Regular and correct care will contribute to
maintaining the beauty and value of your
Audi. Furthermore, good care may be a condi ­
tion for substant iat ing a warranty claim
should corrosion damage or pa int defects oc­
cur.
Your authorized Audi R8 dealer has a variety
of
dedicated vehicle-care products. Please
make sure you apply them correctly .
.8, 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 pol ish remover or other volatile
fluids. They may be toxic, flammable or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ignit ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, etc. without pro­
tecting your hands and arms. You may cut yourse lf on sharp-edged metal parts.

page 146, General
information .
Test the brakes carefully
each time you wash the vehicle.
@ For the sake of the environment
Select only environmentally friend ly clean­
ing products . Leftover cleaning products
should not disposed of in the household
waste.
Care of exterior
Washing your vehicle
T he longer i nsect remains, bird dropp ings,
tree res in , road and indust rial dust, tar, soot
part icles, road salt, and other aggressive de­
posits remain on the vehicle surface, the more
lasting their destructive effect will be . High
temperatures, for example from intense sun­
li ght, intens ify the corrosive effect.
After the end of winter road salting, the un­
derside of the vehicle should be thoroughly
washed .
Automatic car washes
Before going through an automatic car wash,
yo u should take the usual precautions (closing
the windows). If your vehicle has special ac­ cessories -e.g . spoilers, radio antenna -it is
best to speak to the operator of the car wash
c:> (D .
Only use car washes where the vehicle re­
mains stationary and the cleaning equipment
moves aro und the vehicle 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 power washer
When washing yo ur vehicle with a power
washer, be sure to follow the operating in­
structions for the power washer . This applies
particularly to the
pressure and the spraying
distance.
Maintain sufficient distance from
soft materials such as rubber hoses, sound
deaden ing mater ial, and the parking aid sen ­
sors* that are located in the front or rear
bumper .
Do not use washers with
a rotating jet or a
nozzle spraying
a high pressure jet of water in
any case. ..,.

(D Note
-Never use chemical solvents (e.g . lighter
flu id, turpentine), waxes, shoe polish or
s imilar products on Alcantara ® surfaces.
- To avoid damage, have stubborn stains
removed by a commercia l cleaning spe­
cialist.
- Do not use brushes, stiff sponges or sim­
ilarly abrasive cleaning aids.
Safety belts
Heavily soiled safety belts may not retract
properly .
~ Keep belts clean.
~ For cleaning, use a mild soap and water sol­
ution. Let belts dry thoroughly and away
from direct sunlight.
~ Do not allow inertia reel safety belts to re­
tract before they are completely d ry.
~ Check the condition of your safety belts reg­
ularly.
A WARNING
Damaged safety belts can break in a crash.
- Any thing tha t might damage you r safety
belts co uld mean that you and your pas ­
sengers wo uld not be adequately pro­
tected in an accident.
- Safety belt performance depends on cor­ rect installation . Never remove belts
from the vehicle to clean them.
- Do not use chemical cleaning agents,
bleach o r dyes . They have corrosive prop­
erties which weaken the webbing.
- When cleaning your safety belts, inspect
them for damage. If you discover dam­
age, see your authorized Audi dea ler.
- Always read and heed all WARNINGS and
the informat ion
¢page 156.
1) Use o nly the correct cleaning sol utio ns. Neve r use gas­
oline or d iese l fuel.
Cleaning and protec tion
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Corrosion p rotection
The engine compartment and transmission
have been corrosion-protected at the factory.
Good anti-corrosion treatmen t is very impor­
tant, partic ularly in the winter.
If the vehicle
is frequently driven on salt treated roads, the
entire engine compartment and plenum panel
shou ld be thoroughly cleaned at the end of
winter and retreated to prevent salt damage .
At the same time, the underside of the veh icle
shou ld be washed as well.
If the engine compartment is cleaned at any
time with grease remov ing solutions
1>, or if
you have the engine washed, the a nti-corro­
s ion treatment is almost always removed as
well.
It i s therefo re essentia l to have a long­
lasti ng corrosion protection reapplied to all
su rfaces, seams, joints and components in the
engine compa rtment .
A WARNING
--=
Be aware: The eng ine compartment of any
motor veh icle is a potentially hazardous
area.
- Before work ing in the engine compart­
ment, be sure to read the information
¢page 172.
-Before reaching into the front p lenum
panel, a lways remove the ignit ion key.
Otherwise, the w indshield wiper system
could u nintentionally be sw itched on,
possibly caus ing persona l injury from the
mov ing wipe r linkage.
- Never reach i nto the area around or
touch the rad iator fan. The aux iliary fan
is tempe ratu re controlled and ca n sw itch
on s uddenly -even when the ignition is
off. .,.

168 Fuel supply and filling your fuel tank
-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
especially well for winter or summer driving .
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time.
(CT) Note
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system.
- Do not use fuels that fail to meet the
specified criteria in this chapter.
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel supplier.
- Do not use fuel for which the contents cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac ­
turers is carbon deposit build-up caused by
the type of gasoline you use.
A lthough gasoline grades differ from one
manufacturer to another, they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
brands include additives to keep engine and fuel
systems clean, they are not equally effec­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadequate
fuels, built-up carbon deposits can rob your
engine of peak performance.

Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the unlocking system should fail, you can
still open the flap manually -for detailed in­
structions see¢
page 170.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data <=>page 225.
The label on the inside of the fuel filler flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see ¢
page 167.
Your vehicle fuel tank has an on-board refuel­
ing vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly while protecting the environment,
please follow this refueling procedure careful­
ly.
.8, WARNING
Under normal operating cond itions, never
carry additional fuel containers in your car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must

transport fuel to use for your lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
ASTM F8S2 -86) .
@ Note
Never drive your vehicle until the fuel tank
is completely dry. The irregular supply of
fue l can cause misfiring. Gasoline cou ld
enter into the exhaust system and damage
the catalytic converter .
Refueling

fig. 131.
Fuel supply and filling your fuel tank 169
Refueling procedure
.. Insert the fuel nozzle from the gasoline
pump into the fuel filler neck as far as it will
go.
.. Select a medium refueling rate so that the
nozzle switches off automatically when the
tank is full.
Putting the fuel cap back on
.. After filling your tank, twist the fuel filler
cap clockwise until you hear a definite click.
.. Close the fuel filler flap.
To avoid fuel spilling or evaporating from the
fuel tank always close fuel filler cap proper ly
and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp ¢
page 26
to come on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injuries.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can
cause a fire.
- Never use a cellular telephone while re­
fueling. The electromagnetic radiation
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle while re­
fueling.
If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling .
- Never smoke or have an open flame any­
where in or near your vehicle when refu-
eling or filling a portable fuel container. ..,.

1 70 Fuel supply and filling your fuel tank
-For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle (for example, in the luggage compart­
ment, or on the trunk). Static electrici­
ty can build up while filling and can ig­
nite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
-A lways keep the filler nozzle complete­
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozzle must always be
in contact with the-container. This will
help prevent static electricity from dis­
charging and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are
highly flammable.
- Always observe local and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers.
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F852-86).
(D Note
If any fuel has spilled onto the car, it
should be removed immediately to prevent
damage to the paint .
@) For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first
time, the tank is full. Do not try to add
more fuel because fuel may spill out. In
addition, the expansion space in the fuel
tank will be filled -causing the fuel to overflow
when it becomes warm and pol­
lute the environment.
(D Tips
- Running your engine while refueling may
cause vapors to escape or even fuel to
spill out of the tank . This would then
shut off the fuel nozzle before the tank
is full.
- Do not refuel your vehicle with the ig n i­
tion switched on. The fuel gauge may
otherwise not indicate the correct fuel
level after refueling .
Unlocking the fuel filler flap
by hand
You can open the fuel filler flap by hand if the
power locking system should fail.
