Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
.,. Wash the whee ls with a sponge o r hose
brush every other week.
.. For deep cleaning afterwards, use only a
dedicated
a ci d-fr ee cast alloy wheel cleaner .
.,. Rub a coat of
liquid w ax onto the r ims every
three month. Be sure to reach and treat all parts of the rim .
To preserve the decorative appearance of the
cast alloy wheels, some special care is neces­
sary . In add it ion to road dirt and salt, brake
dust is also corros ive. If left on for too long,
brake dust ca n cause pitting .
Use only special
acid-free cleaners formulated
for alloy rims . Safe products are available at
your Aud i dealer. Never leave the cleaner on
the r ims longer than spec ified on the label. If
not rinsed off p romptly, the acid co nta ined in
some cleane rs can attac k the th reads on the
wheel bo lts.
Never use abras ive or metal polishing clean­
i n g agents. If the protective coat ing has been
chipped, e.g. by k icked up road dirt, touch it
up as soon as possib le.

Cleaning and protec tion 209
Body cavity sealing
The body cavity sealing does not need to be
checked .
All body cav ities which could be affected by
corros io n have been thoroughly protected at
the factory .
This sealing does not require any inspection or additional treatment. If any wax should seep
out of the cavity when the ambie nt tempera­
ture is high, it can be removed with a plastic
scraper and a su itable solvent .
A WARNING
Solvents can be dangero us.
- Benz ine is flammab le and toxic. If you
use benz ine fo r removing the wax, keep
sparks, flame and lighted cigarettes
away. Never dump ben zine on the
groun d, into open streams or down sew­
age drains .
- Be s ure to obse rve all safe ty and environ­
men tal reg ulations. Fo llow all instruc­
tions on the container.

ing p roducts that have been tested and ap­
p roved fo r you r vehicle.
Care of interior
Infotainment components
The MMI/RSE* display may be cleaned with a
soft cloth and commercially-ava ilable "LCD
cleaner" . The cloth should be coated lightly
when the clean ing solution when cleaning the
d isplay.
The MMI/RSE* contro ls must be cleaned first
with a brush so t hat dirt does not ente r the
un it or enter between the buttons and the
housing. Then wiping the controls with a cloth
dampened with dish detergent and water is recommended.
CJ) Note
- To avoid sc ratch ing the disp lay, you
shou ld never clean it dry.
- To prevent damage, ma ke sure fluids do
not enter the controls.
Aluminum trim
Use only n eutral-pH products to remove spots
and deposits from aluminum surfaces.
Chrome ca re products and alkaline cleaners
will attack aluminum s urfaces and can dam­
age them over time.
A WARNING
A lways read and heed all WARNINGS and
other information
c> page 204.
Fabrics and fabric coverings
Fabr ics and fabric cover ings (e .g. seats, door
trim panels, etc.) should be cleaned at regular i ntervals w ith a vacuum cleaner. This removes
su rface di rt particles which could become em ­
bedded in the fabri c through use. Steam
cleaners should not be used, because the
steam tends to p ush the dirt deeper into the
fabric and lock it there.
Normal clean ing
Generally, we recommend using a soft sponge
o r a lint-free microfiber clo th to the clean fab­
ric. Brushes shou ld only be used for carpets
and floor mats, since other fabric surfaces
could be harmed by brushes.
Norma l su rface stains can be cleaned using a
commercially available foam cleaner . Spread
the foam on the s urface of the fabric with a
soft sponge and work it in gently. Do not satu­
rate the fabric. Then pat the foam dry using
absorbent, dry cloths (e.g. m icrof iber cloth)
and vacuum it after it has dried completely.
Cle anin g sta ins
Stains caused by beverages (e .g. coffee, fruit
juice, etc.) can be treated with a mild deter­
gent solution. Apply the detergent solution
with a sponge. In the case of stubborn stains, a detergent paste can be applied directly to
the stain and worked into the fabric. After­
wards, use copious amounts of clean water to
remove the rema in ing deterge nt. Apply the
water wit h a damp clo th or sponge an d pat
the fabric dry with an abso rbent, dry cloth .
Stains from choco late or makeup should have
detergent paste (e.g. ox-gall soap) rubbed in­
to them. Afterwa rds, remove the soap with
water (damp sponge) .
Alcohol can be used to treat stains from grease, o il, lipstick or a ballpoin t pen . Melted ..,.

grease or dye must be patted off using ab ­
sorbent materia l. It may be necessary to re­
treat the areas with detergent paste a nd wa­
ter.
I n the case of genera l soiling of the uphols­
tery and cover material, we recommend hiring
a specialist that has the equ ipment to clean
the seat covers and other fabric surfaces by
shampooing and spray extraction.
A WARNING
Always read and heed all WARNINGS and
the information
Q page 204.
Open Velcro fasteners on your clothing can
damage the seat cover. Please make sure
that Velcro fasteners are closed.
Plastic parts and instrument panel
Always use a clean cloth moistened in clear
water to clean these areas. For pers istent dirt
use an Audi approved
s olvent -fr ee plasti c
cleane r/pro te cta nt.
A WARNING
So lvents can change the properties o f
some plastics and make it ha rder for the
airbag to dep loy.
- Never clean the instr ument pane l o r the
s u rface of airbag modules with cleaning
products that contain solvents.

Natural leather
Appl ies to vehicles: with natural leather
Audi makes great efforts to maintain the
properties, natural look and feel of interior
leather .
General
We offe r ma ny d iffe rent types of leathe r o n
ou r vehicles. Most are diffe rent types of nappa
l eather, which has a smooth surface and
comes in various colo rs .
T he intensity of the co lor determ ines the visu­
al cha racteristics and appea ran ce. If the su r­
f a ce of the leather has a typ ica l na tural look,
then the leather is a nap pa lea ther that has
been left in a relative ly natura l condition . This
leather offers particularly good comfort and
breathes well. Fine veins, closed grains, insect
bites, sk in fo lds, and subt le variations in color
rema in v isible. These character istics demon­
strate that the mate rial is natural.
Natura l nappa leather is not covered by a co l­
or finish. It is therefore more sens it ive to soil­
ing and wear, which is someth ing you need to
conside r if ch ildren, animals or other factors
might prove to be part icu larly hard o n the
leat her .
By contrast, leather types that are covered by
a colo red finish layer are more durable. This
has a positive effect on the leather 's resist­
an ce to wea r and soiling in da ily use. On the
othe r hand, the typica l charac teristics of natu­
ral leathe r are barely or not appa ren t. Howev­
er, this does not mean that the leathe r itse lf
is of infe rior quality. •
•

~ Apply the product very sparing ly .
~ Wipe it off with a damp cloth.
If you have any questions abo ut cleaning and
caring for the leather in your vehicle, it is best
to contact your authorized Audi dealer, who
will be glad to help you and tell you about our
fu ll range of leather care products, such as:
- Leather cleaning and care kit
- Creams to care for colored leathe r
- Spot removers for ballpo int pens, shoe pol-
ish , etc.
- Oil/grease dissolv ing spray
- New and upcoming products.
A WARNING
Always read and heed all WARNINGS and other information
~ page 204.
CD Note
- Never use chemical solvents (e.g. lighter
flu id, turpentine), waxes, shoe polis h or
s imilar products on the leather surfaces
i n your Audi.
- To avoid damage, have stubborn stains removed by a commerc ial cleani ng spe­
cia list .

214 Cleaning and protection
-When cleaning your safety belts, inspect
them for damage.
If you discover dam­
age, see your Audi dealer .
- Always read and heed all WARNINGS and
other information
c> page 204.
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Always switch off the ignition before clean­
ing the engine
c> .&..
Plenum panel
Remove leaves from the plenum pane l in front
of the windsh ield under the engine compart­
ment. This prevents the water dra in ho les
from becoming blocked, and it prevents de­
bris from entering the vehicle interior through
the heating and venti lation ducts .
Corrosion protection
The engine compartment and transmission
have been corrosion -protected at the factory.
Good ant i-corrosion treatment is very impor­
tant, particularly in the winter. If the veh icle
is frequent ly driven on salt treated roads , the
enti re engine compartment and plenum panel
should be tho roughly cleaned at the end of
winter and retreated to prevent sa lt damage.
At the same time, the underside of the vehicle
should be washed as we ll.
If the engine compartment is cleaned at any
time with grease removing solutions
1l, or if
you have the engine washed, the anti-corro­ sion treatment is a lmost always removed as
well. It is therefore essential to have a long­ lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the
engine compartment .
1l Use o nly the co rrect cle anin g so lu ti on s. Ne ver use gas­
o lin e or d ie se l fuel.
A WARNING
Be aware: The eng ine compartment of any
motor vehicle is a potentially hazardous
area .
- Before work ing in the engine compart­
ment, be sure to read the information
c> page 220.
-Before reach ing into the front panel, al ­
ways sw itch off the ignition . Otherwise,
the windshield wiper system could unin­
tentionally be switched on, possibly
causing personal injury from the moving
wiper linkage .
- Never reach into the area around or
touch the radiator fan. The auxiliary fan
is temperature controlled and can sw itch
on suddenly -even when the ignition is
off.
- Do not wash, wax or dry the engine with
the engine running . Moving or hot parts
could injure you.
- Do not clean the underside of the chas­
sis, fenders, wheel covers, or other hard
to reach parts without protecting your hands and arms . You may cut yourself on
sharp-edged metal parts.
-Always read and heed all WARNINGS and
other information

216 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
espec ially we ll for winter or summer driv ing.
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 fai l to meet the
specified criteria in this chapter.
- If yo u are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel sup plier.
- 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 respons ibility 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 l ems 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 g rades contain
substances that can cause deposits to co llect
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 a re 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
f uels, carbon deposit build-ups can rob yo ur
engine of peak performance.

Fuel filler neck
The fuel filler neck is located on the right rear
s ide panel behind the fuel filler flap.
If the power locking system should fail, you
can still open the flap manually- for detailed
instructions see
¢page 218.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢ page 276.
The label on the inside of the fuel fi ller flap
tells you the correct fue l for your veh icle. For
more information about fuel specifications,
see
¢ page 215.
Your vehicle fuel tank has an on board refuel­ li ng 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 wh ile protecting the environment,
please fo llow 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 empty. The irregular supply
of fuel can cause misfiring. Gasoline could
enter the exhaust system and damage the
catalyt ic converter.

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
fue l 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
fue ling. The electromagnet ic 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.
