Vehicle care and clean ing
General information
Regular, proper care helps to maintain your
vehicle 's value. It can also be a requirement
when submitting warranty claims for corro ­
sion damage and paint defects on the body .
The required cleaning and care products can
be obtained from your authorized Audi dealer
or a qualified workshop . Read and follow the
instructions for use on the packaging.
A WARNING
-Us ing clean ing and care products incor­
rectly can be dangerous to your hea lth.
- Always store cleaning and care products
out of reach of children to reduce the risk
of poisoning.
@) For the sake of the environment
-Preferably use environmentally-friendly
products when buying cleaning agents.
- Do not d ispose of leftover cleaning and
care products with household trash .
Car washes
-
The longer that deposits such as insects, bird
droppings, tree sap or road salt remain on the
vehicle, the more the surface can be dam­ aged. High temperatures such as those
caused by sunlight increase the corrosive ef­
fect.
Before washing, wet heavy deposits w ith plen­
ty of water.
Also, wash the underside of your vehicle once road salt stops be ing used for the season.
Pressure washers
When washing your vehicles with a pressure
washer, always follow the operating instruc­
tions provided w ith the pressure washer . Th is
is especially important in regard to the pres ­
sure and spraying distance. Do not aim the
spray directly at seals on side w indows, doors,

the hood, the rear lid or the sunroof* or at
tires, rubber hoses, insulating material, sen­ sors* or camera lenses* . Keep a distance of at
least 16 inches (40 cm).
Do not remove snow and ice with a pressure
washer.
Never use rotary nozzles or high pressure noz­
zles.
The water temperature must not be above
140 °F (60 °C) .
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows and roof* are
closed and the windshield wipers are

working down using a soft sponge or cleaning
brush. Use solvent-free cleaning products.
Washing vehicles with matte finish paint
by hand
To avoid damaging the paint when washing,
first remove dust and large particles from
your vehicle. Insects, grease spots and finger­ prints are best removed with a special cleaner
for matte finish paint.
Apply the product using a microfiber cloth. To
avoid damaging the paint surface, do not use
too much pressure .
Rinse the vehicle thoroughly with water. Then
clean using a neutral shampoo and a soft mi­
crof iber cloth.
Rinse the vehicle thoroughly again and let it
air dry . Remove any water residue using a
shammy.
Stubborn deposits such as bi rd droppings or
tree sap are best removed with plenty of wa-
ter and a microfiber cloth.

210 Vehicle care and cleaning
A WARNING
-Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk
of accidents .
- To reduce the risk of cuts, protect your­
self from sharp metal components when
washing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef­
fect may be delayed due to moisture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applications.
(!;) Note
- If you wash the vehicle in an automatic
car wash, you must retract the rear spoil­
er if necessary, and fold the exterior mir­
rors in to reduce the risk of damage.
Power folding exterior mirrors* must on­
ly be folded in and out using the power
folding function.

the vehicle in direct sunlight. -
To reduce the risk of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:
- To reduce the risk of damage to the
surface, do not use polishing agents or
hard wax.
- Never use car wash cycles that apply
protective wax.
It can destroy the
matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte finish paint. The paint could be
damaged when the stickers or magnets
are removed.
@ For the sake of the environment
Only wash the vehicle in facilities specially
designed for that purpose. This will reduce
the risk of dirty water contaminated with
oil from entering the sewer system.

Gasoline
Fuel supply
Appl ies to vehicles: with gasoline engine
Using the right fuel helps keep the environ­
ment clean and prevents engine damage .
Fuel recommendation
The fuel recommended for yo ur vehicle is un ­
l e aded premium
grade gasoline . Audi recom­
mends using TO P TI ER D ete rgent Gaso line
wi th a m inimum octane ra ting o f 91 A KI ( 95
RO N). Fo r more informa tio n o n TOP TIER De­
tergent Gasoline, p lease go to the o fficia l
websi te (www. topt iergas .com) .
The re commended gasoline octane rati ng for
your engine can a lso be fo und o n a label loc at­
ed on the ins ide of the fuel filler flap . This ra t­
ing may be specif ied as AK I or RO N.
Your veh icle may also be operated using un­
l eaded regular gasoline with a minimum oc ­
tane rating of 87 AKI/91 RO N. However, using
87 A KI/91 RON octa ne fue l wi ll slightly re ­
d uce eng ine perfo rmance .
Use unleaded ga soline only. U nleaded g aso­
l ine is available th rougho ut the USA, Canada,
a nd i n most E uropean countries . We recom ­
mend that you do not ta ke yo ur vehicle to
areas or co untries where unleaded gasoline
may not be ava ilable.
F or mo re informat io n on refue ling your ve hi­
cle, see~
page 216.
Octane rating
Octane rating ind icates a gaso line's abili ty to
res ist eng ine dam ag ing "knoc k" ca use d by
premature ign ition and detona tion. Therefore,
buy ing the correct grade of gaso line is very
important to he lp prevent possible engine
damage and a loss of engine performance.
Gasoline mos t commonly used in the Unite d
States and Canada has the following octane r
atings t hat can usu a lly be found on the fi ller
pump:
- Premium Gra de: 91 -96 A KI
- Regular Grade : 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti K nock In d ex = (R+M )/2 = (RON
+ MON)/2
R ON= Resear ch Octane Numb er
MON = Motor Octane Num ber .
(D Note
-Do not use a ny fue l w it h o ctane rat ings
lower tha n 87 A KI or 91 RO N othe rwise
expensive engi ne damage w ill occur.
- Do
not use leaded gasoli ne. The use of
leaded gasoline w ill severely damage
yo ur v ehicle's cata lytic co nve rter and its
ability to co ntrol exha ust em issions .
Blended gasoline
Applies to vehicles: with gasoline engine
Use of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether )
You may use unleaded g asoline blende d wi th
alcohol o r MTBE (commonly referred to as
oxygenates) if the blende d mixture meets t he
f o llow ing criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti -kno ck index must be 87 A KI or higher.
- Blend must contain no more t han 3% meth-
anol.
- Blend must contain more than 2% co -sol -
vents.
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
- Anti -knock index must be 87 AKI or higher .
- Blend must not conta in mo re tha n 15%
ethanol.
Blend of ga soline and MTBE
- Anti-knock index must be 87 AKI or higher. IJll,

,...., ..,., ,....,
-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 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 .
(D 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 fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- 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 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.
Although 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 supply and filling your fuel tank 215
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more info rmation on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
fuels, carbon deposit build-ups can rob your
engine of peak performance.
Q) Note
Damage or malfunction due to poor fue l
quality is not covered by the Aud i New Ve­
hicle Limited Warranty.
Diesel fuel
Applies to veh icles: w ith diese l eng ine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2. The ULS D No. 2 meets the ASTM D975.
D iesel fuel w ith concentrations of biodiese l
highe r than 5 % such as Bll, B2O or BlOO are
strictly prohib ited.
Serv ice stat ion fuel pumps are labeled with
the correct fuel informat ion for easy recogn i­
t ion by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav­
eling to other countries.
ULSD No. 2 can become thicker in very cold
temperatures, and this can impair the en­ gine's start ing and running. Depending on the
season, gas stat ions provide ULSD No. 2 that
flows better in cold temperatures so that you
can continue operating your vehicle as usua l.
(D Note
-Your vehicle's diesel engine was de­
signed soley for use with ULSD No. 2.
Th erefore, never use gasoline, heating
oil, other f uels or flow improvers . These
contain substances that wi ll severely
damage the fuel system and the engine. .,.

216 Fuel supply and filling your fuel tank
Such damage will not be covered by your
New Vehicle Limited Warranty.
- If you p ut any amount of incorrect fuel in
the fue l tank, do not start the engi ne un­
der any circumstances. Immediately con­
tact the nearest authorized Audi dealer
or authorized Audi Service Facility for as­
s istance. These fuels contain substances
that can severely damage the fuel sys ­
tem and the engine if the engine is start­ ed.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system should fa il, you
can st ill open the flap manually -for detailed
instructions see
c;, page 218.
You can find the fue l tank capacity of your ve­
hicle in
c;, page 290.
The label on the inside of the fue l filler flap
tells you the cor rect fuel for your vehicle . Fo r
more information about fuel specifications,
see
c;, page 214.
Your veh icle fuel tank has an onboard refue l­
ling 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 whi le protecting the env ironment,
please follow this refueling procedure careful­
ly .
A WARNING
Under normal operating conditions, neve r
carry additiona l fuel containers in you r 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 fue l to use for yo ur 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 F852 -86).
(D Note
Never drive your vehicle until the fue l tank
is completely empty. The irregu lar supply
of fue l can cause misfiring. Gasoline could
enter the exhaust system and damage the
catalytic converter .

Refuelling procedure
"'Insert the fuel nozz le from the gasoline
pump into the fue l filler neck as far as it will
go.
"' Se lect a medium refuelling rate so that the
noz zle switches off automatically when the
tank is full.
Putting the fuel cap back on
"'After filling your tank, twist the fuel fi ller
cap clockwise as far as it will go.
"' Close the fuel filler flap .
To avoid fuel spi lling or evaporating from the
fuel tank always close fuel fi ller cap properly
and comp letely. An improperly closed fuel fill­
er cap may also cause the MIL lamp¢
page 29
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 eng ine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel f iller neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and ove rflow ing fuel can
cause a fire.
- Never use a cellular telephone while re­
fueling. The elect romagnetic radiation
can cause sparks that can ignite fue l va­
pors and cause a fire.
- Never get back into you r vehicle while re­
fueling. If in exceptiona l circumstances
yo u must get back in your vehicle wh ile
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 you r vehicle when refu­
eling or filling a portable fuel container .
- For your safety, we strongly recommend
that you do not travel w ith a portable
Fuel supply and filling your fuel tank 217
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 portab le fue l conta iner
on the ground before fi lling.
- Always keep the filler nozzle complete­
l y inside the portable container before
and during filling.
- If filling a portab le container made of
metal, the fi ller nozzle must always be
i n contact with the conta iner. This will
help prevent static electric ity 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 containers .
- 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 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
l ute the environment . •
•

218 Fuel supply and filling your fuel tank
@ Tips
-Running your engine while refuelling
may cause vapors to escape or even
cause fue l to spill out of the tank. This
would then shut off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle w ith the igni­
tion switched on. The fuel gauge may
otherwise not indicate the correct fuel
level after refuelling.
- Diesel vehicles* are equipped with a die­
sel m isfueling protector. It allows the
vehicle to be fueled only w ith a diesel
fuel pump nozzle. A worn or damaged
nozzle or a nozzle that is too small may
not be able to open the diesel misfueling
protector . If this is the case, try turning
the nozz le before inserting it in the fue l
filler neck, use a different fuel pump or see your authorized Audi dealer or au­
thorized repair facility for assistance.
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from
the inside.
Fuel filler flap emergency release
You can open the fuel filler flap by hand if the
power locking system should fail.
