Vehicle care and cleaning 171
Rinse the vehicle thoroughly again and let it
air dry. Remove any water residue using a
shammy .
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 r isk of cuts, protect your­
self from sharp metal components when
wash ing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef­
fect may be de layed 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 fold the exterior m ir­
rors in to reduce the ris k of damage to
the mirrors. Power folding exterior mir ­
rors* must only be folded in and out us ­
ing the power folding function. -
To prevent paint damage, do not wash
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 magnet ic
signs on vehicle parts painted w ith
matte fin ish 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 spec ially
designed for that purpose . This will red uce
the r isk of dirty water contam inated with
oil from entering the sewer system.

Fuel supply and filling
your f uel tank
Gasoline
Fuel supply
Using the right fuel helps keep the environ­
ment clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is un­
leaded premium
grade gasoline. Audi recom­
mends using TOP TIER Detergent Gasoline
with a minimum octane rating of 91 AKI (95
RON) . For more information on TOP TIER De­
tergent Gasoline, please go to the official
website (www.toptiergas.com).
The recommended gasoline octane rating for
your engine can also be found on a label locat­
ed on the inside of the fuel filler flap. This rat­
ing may be specified as AKI or RON.
Your vehicle may also be operated using un­ leaded regular gasoline with a minimum oc­
tane rating of 87 AKI/91 RON. However, using
87 AKI/91 RON octane fuel will slightly re­
duce engine performance.
Use unleaded gasoline only. Unleaded gaso­
line is available throughout the USA, Canada,
and in most European countries. We recom­
mend that you do not take your vehicle to
areas or countries where unleaded gasoline
may not be available.
For more information on refueling your vehi­
cle, see~
page 176.
Octane rating
Octane rating indicates a gasoline's ability to
resist engine damaging "knock" caused by
premature ignition and detonation. Therefore,
buying the correct grade of gasoline is very
important to help prevent possible engine
damage and a loss of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane ratings that can usually be found on the filler
pump:
Fuel supply and filling your fuel tank 175
- Premium Grade: 91 -96 AKI
- Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Knock Index= (R+M)/2 = (RON
+MON)/2
RON= Research Octane Number
MON= Motor Octane Number.
@ Note
-Do not use any fuel with octane ratings
lower than 87 AKI or 91 RON otherwise
expensive engine damage will occur.
- Do
not use leaded gasoline. The use of
leaded gasoline will severely damage
your vehicle's catalytic converter and its
ability to control exhaust emissions.
Blended gasoline
Use of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether)
You may use unleaded gasoline blended with
alcohol or MTBE (commonly referred to as
oxygenates) if the blended mixture meets the
following criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knock index must be 87 AKI or higher.
- Blend must contain no more than 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 contain more than 15%
ethanol.
Blend of gasoline and MTBE
- Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15%
MTBE.

ways observe local and state laws regard­
ing the use, transportat ion and storage of
such fuel containers . Make certain the con­
t ainer meets industry standards (ANSI/
AS TM F 852 -86).
(D Note
Never drive yo ur vehicle unt il the fuel tank
is completely empty . The irregular supp ly

Refueling procedure
• Insert the fuel nozzle from the gasoline
pump into the fuel fi ller neck as far as it wi ll
go .
• Select a medium refueling rate so that the
no zz le switches off automatically when the
tank i s full .
Putting th e fuel cap bac k on
• After filling your tank, twist the fuel cap
clockw ise as far as it will go .
• Close the fue l filler flap.
T o avoid fuel spill ing or evaporating from the
fuel tank always close fuel cap properly and
completely . An improper ly closed fuel filler
cap may also cause the MIL lamp ¢

to come on.
A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injur ies .
- 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. Fue l spray and overflowing fuel can
cause a fire .
- Never use a ce llu lar telephone while re­
fue ling. The electromagnet ic rad iation
can cause sparks that can ignite f uel va­
pors and cause a fire.
- Never get back into yo ur vehicle while re­
fuel ing.
If in excep tional 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 electr icity can
cause sparks that can ignite fuel vapors
released during refueling.
- Never smoke or have an open f lame any­
where in or near your veh icle when refu ­

floor pan from underneath regularly. If
you see spots from oil or other vehicle flu­
ids, have your vehicle inspected by an au­
thorized Audi dealer.

186 Checking and filling
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
qu ires little attention .
The cooling system has been filled at the fac­
tory with a permanent coo lant which does not
need to be changed. The coolant consists of a
mixture of spec ially conditioned water and the
manufacturer's glycol-basedcoolant addi-
tive G13 antifreeze with ant icorros ion addi­
tives (50% for USA models; 60% for Ca nada
models) . This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's cooling system from
corrosion and scaling.
It a lso raises the boil­
ing point of the coo lant.
Do not reduce the concentration o f the coo l­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protect ion is too low,
the coolant could freeze and damage the veh i­
cle heating and engine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- - 40 °F ( -40 °C) Canada.
I f you must add coo lant, use a mixture of wa­
ter and coolant addit ive. Mixing the coolant
additive with distilled water is recommended.
_& WARNING
Before yo u check anything in the engine
compartment, always read and heed all
WARNINGS
~ &. in Working in the engine
compartment on page 179.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
-
your vehicle is sufficient to meet the cli­ mate conditions . This is especia lly impor­
tant if you live in a reg ion where the win­
ter is extreme ly cold. If necessary, in­
crease the proportion of coolant add itive
to 60% .
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive G12++ or G13 for your vehicle.
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­ rosion protection. The resulting corro­
sion can cause a loss of coolant and se­
rious engine damage .
- Do not add any type of rad iator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair flu id may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

188 Checking and filling
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure re lief valve in the cap when the en ­
g ine becomes hot.
A WARNING
- The coo ling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps.
- Turn
off the eng ine and a llow it to 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 slowly and very ca refully
i n a co unte r-clockwise d irection while
apply ing light, downward press ure 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 certa in
conditions, the ethylene glyco l in en­
g ine coolant can ca tch f ire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its original container and we ll
o ut of the reac h of children.
- If you drain the coolant, it must be
caught and safely stored in a p roper con­
ta iner clear ly ma rked "poison".
(D Note
- Do not add coolant if the expansion tan k
i s empty. A ir could enter the cooling sys­
tem and damage the eng ine. If this is
the case, do not continue driving. Seek
professional assistance.
- Coolant po llutes the e nv ironment and
could cause an engine fire. Excess coo l­
ant will be forced ou t through the pres ­
su re re lief v alve in the ca p when the en­
gine becomes hot .
- If, in an emergen cy, only water can be
added, the corre ct ratio be twee n wa te r
and antifr eeze¢
page 186 must be re ­
stored as soon as possib le .

Radiator fan
The radiator fan switches on automatically by
itself
T he rad iator fan is driven by the engine v ia the
V-belt. The viscous clutch regulates the spee d
of the fan acco rding to the temperature of the
