Exhaust tail pipes
Road salt and other corrosive materials will
damage the material in the exhaust tail pipes
if they are not cleaned regularly . Do not clean
the tail p ipes with wheel cleaner, paint pol ish,
chrome po lish or other abrasive cleaners.
C lean the tail p ipes with car ca re p roducts
that are su itable for stain less stee l.
Your author ized Audi dealer can provide clean­
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 care 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 200.
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 fabric 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 cloth 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 and 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 ..,.

208 Clea ning and protec tio n
Care and handling
Because of the exclusive nat ure of the types of
l eather that Audi uses and their unique prop ­
erties (such as sensitivity to oils, grease, soi l­
ing, etc.), you will need to be somewhat care­
fu l w ith these leathers, and a certain type of
care is required. For examp le, dark clothing
materials can d iscolor leather seats (especial­
ly if such cloth ing is damp and was not dyed
correctly). Dust and dirt part icles in pores,
folds, and seams can have an ab ras ive effect
and can damage the leather surface as well as
weaken seams.
The leather should be cleaned regularly as
needed. After having been used for a re latively
long t ime, your leather sea ts will acquire a
rich aged finish. This is a characteristic of nat­
ura l leather and a sign of true quality .
I n order to maintain the va lue of th is natura l
p rod uct over the life of your vehicle, you
should follow the recommendations below :
(D Note
-To keep you r leather from bleaching out,
do not a llow it to be exposed to bright
sunl ight for long periods of time. If you
have to leave the vehicle parked o utside
for long periods, cover the leather to
protect it from d irect exposure to sun­
li ght.
- Sharp objects on clothing, such as zip­
pers, rivets or sharp pieces on be lts can
leave permanent scratches or scrape
marks on the surface of the leather.
- After each time you clean the leather and
at regu lar intervals, use a leather preser­
vat ive creme that conta ins UV-blockers
and that works into the leather. This
creme wi ll nourish and moistur ize the
l eather, helping it to b reathe and stay
supple.
It also helps to bu ild up a protec­
tive coat ing on the s urface.
- Clean the leather every 2 -3 months,
and clean any areas that get soiled. - Remove fresh marks made by ballpoint
pens, ink, lipstick, shoe polish, etc. as
soon as poss ible.
- Preserve the color of the leather as need­
ed by using a specia l co lored leather care
creme to touch up areas of uneven color.
Cleaning and caring for leather
upholstery and trim
Applies to vehicles: with natural leather
Natural lea ther requires special care and a t­
tention .
Normal cl ean ing
.. Clean soiled areas with a slightly moistened
cotton or woolen cloth .
More stubborn dirt
.. More s tubbor n dirt ca n be removed using a
cloth saturated with a mild soap solut ion (2
tablespoons mild liquid soap).
.. Never allow the soap solution to saturate
the leath er, and make certain that no water
soak s into the seam s.
.. Wipe off the soap solution with a soft, dry
cloth .
Cleanin g spot s
.. Remove fresh wate r-b as ed spots (such as
coffee, tea, juices, blood) with an absorbent
cloth or paper towel.
.. Remove fresh
grease or oil -b ased spots
(such as butter, mayonnaise, chocolate) with
an absorbent cloth or paper towel, or use
the cleaner from the leather care kit if the
spot has no t yet penetrated into the surface
of the leathe r .
.. Use an oil/grease d issolving spray, if
o il/
grea se sp ots ha ve d ried on.
.. Remove specific kinds of spots (ballpoint
pen, fe lt marker, fingerna il polish, water­
based pa int, shoe polish, etc.) with a spot
remover specifically formulated for lea ther.
L e athe r care
.. Every half year use an approved leather care
product (available from your Audi dealer) to
care for the leather . .,.

210 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 200.
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 thoroughly 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 216.
-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
c> page 200.

212 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.
(D Note
'
Damage or malf u nct ion due to poor fuel
quality is not covered by the Aud i New Ve­
hicle Limited Warranty.
Fuel tank
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 214.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢ page 272.
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 211.
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.
Refuelling

• Unscrew fuel filler cap counter-clockwise
and hang it on the fuel filler flap
~ fig. 164 .
Fuel supply and filling your fuel tank 213
Refuelling procedure
• Insert the fuel nozzle from the gasoline
pump into the fuel filler neck as far as it will
go.
• Select a medium refuelling 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 as far as it will go.
• Close the fuel filler flap.
To avoid fuel spill ing 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 2 7
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
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.
- Never smoke or have an open flame any­
where in or near your vehicle when refu­
eling or filling a portable fue l container.
- For your safety, we strongly recommend
that you do not travel with a portable

214 Fuel supply and filling your fuel tank
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 bui ld up while filling and can ig­
nite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
- Always keep the filler nozzle complete­
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozz le must always be
in contact with the container. This will
help prevent static electricity from dis­
charging and cause a fire .
- Never spill 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 conta iners .
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F8S2 -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 noz zle
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 whi le refue lling
may cause vapors to escape or even
cause fuel to spi ll out of the tank. This
would then shut off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may otherwise not ind icate the correct fuel
level after refuelling .
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from
the ins ide .
Fuel filler flap emergency release
You can open the fuel filler flap by hand if the
power locking system should fail.

224 Check ing and filling
cold engine, the coo lant level should be be ­
tween the "min" and "max" markings. When
the engine is warm, the level may be s light ly
above the "max" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
c:> page 218.
To obtain an accurate reading, the engine must be switched
off.
The expansion tank in you r vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning light in the Auto-Check System
c:> page 15 will
i l lum ina te unti l you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time.
Coolant los s
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
sea led system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheat ing.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect yo ur face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
top of the cap.
- To avoid be ing burned, do not spill ant i­
freeze or coolant on the exhaust system
'
or hot engine parts. Under certain cond i­
tions, the ethylene glycol in engine coo l­
ant can catch fire.
(D Note
Do not add any type of radiator leak sea l­
ant to your vehicle's engine coolant. Add­ i ng radiator repa ir fl uid may adverse ly af­
fect the funct ion and performance of your
cooling system and could result in damage
not covered by your New Veh icle L imited
War ranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the eng ine com­
partment,
always read and heed all W ARN­

E ven in a n emerge ncy, if coolant add i-
t ive G12 ++, G 12+ or G12 is not available, do
not use a d iffe rent addit ive. Use plain water
instead unti l you can get the correct additive
and can restore the correct ratio . This shou ld
be done as soon as possible.
If you have lost a considerab le amount o f
coolant, then you sho uld add cold antifreeze
and co ld water on ly w hen the engine is cold.
Always use

_& WARNING
-The cooling system is under pressure and
can get very hot. Reduce the risk of
scald ing from hot coolant by following
these steps.
- Turn
off the engine and a llow itto cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slow ly and very carefully
in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being burned, do not spi ll an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts . Under certain
conditions, the ethylene glycol in en­
g ine coolant can catch fire .
- Antifreeze is poisonous. Always store an­
tifreeze in its or iginal containe r and we ll
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Coolant pollutes the env ironment and
could cause an engine fire. Excess cool­
ant will be forced out through the pres­
su re relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the cor rect ratio between water
and antifreeze ¢
page 223 must be re­
stored as soon as possib le.
@ For the sake of the environment
Drained coolant should not be reused . A l­
ways dispose of used coolant while obse rv­
ing all environmental reg ulations.
Checkin g and fillin g 225
Radiator fan
The radiator fan switches on automatically by
itself.
An auxiliary electric radiator fan switches on
and
off depending on coolant temperature
and other vehicle operat ing cond it ions .
After you switch the engine
off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition
off. It can even switch
on again later by itself ¢&. , if
- the temperature of the engine coo lant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
_& WARNING
-To reduce the risk of personal injury nev­
er touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can sw itch on suddenly
even when the engine is not running.
- The a uxiliary radiator fan sw itches on au­
tomatically when the engine coo lant
reaches a certa in temperature and will
continue to ru n until the coolant temper­
ature drops.
Brake fluid
Checking brake fluid level

226 Check ing and filling
Before you check anything in the engine com­
partment,
always r ea d and heed all W ARN­
INGS
¢ A in Working in the engine compart­
ment on page 216.
• Read the brake fluid leve l from the brake
fluid reservoir
¢ fig. 173. The brake fluid
l evel must be between the
"MIN" and
"MAX" markings .
The location of the brake fluid reservoir can be
seen in the engine compartment illustration
co page 218.
The fl uid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
I f the b rake fluid level falls
considerably be­
l ow the "MIN" mark, the brake wa rning/indi ­
cator light- (U.S.
models) ;II (Canadian
models) will come on
¢ page 14. Do not con ­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized Audi dealer or other quali­
fied fac il ity and the cause corrected. If the
brake fluid level is too low, the brake warn ing/
i ndicator light w ill illuminate. Contact an au­
thor ized Audi dealer
imm ediatel y.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moistu re from the a ir . If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
b rake fluid w ill also decrease considerably and
dec rease braking per formance.
Therefore, the brake flu id must be changed
ev ery tw o y ear s. Always use new b rake fluid
which confo rms to Fede ral Motor Vehicle
Standard "FMVSS 1 16 DO T 4".
The brake flu id rese rvoi r can be difficult to
r each, therefo re , we re commend that yo u
have the brake fl uid changed by yo ur a utho r­
ized
Audi dealer. Your dea ler has the correct tools, the
right brake flu id and t he know -how
to do this for you.
A WARNING
-- Brake flu id is poisonous. It must be stor-
ed only in the closed or igina l container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake f lu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
spe cifi cation
J 17 03 and conforms to
Federa l Motor Vehicle Standard 1 16 .
Always chec k with your authorized A udi
dealer to make sure yo u are using the
correct brake fluid. The cor rect type of
brake flu id is also ind icated on the
brake f lu id reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left i n the system too
long . This can se riously affect the effi­
c iency of the brakes as well as your
safety . T h is i:ou ld result in an ai;i;ident.
(D Note
Brake fluid will damage the pai nt of you r
vehicle .
@ For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
