212 Fuel supply and filling your fuel tank
- Anti-knock index must be 87 AKI or higher.
- 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.
CD Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only
be used in vehicles with flex ible fuel en­
gines. Using high ethano l fuel in vehicles
not equipped with flexib le fue l eng ines
can cause severe engine damage.
- Methanol fuels which do not mee t 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 identif ied.
- 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 driveab ility and performance prob­
le ms due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Ethanol fuel (Bio-ethanol)
Applies to vehicles: wit h flexible fue l e ngi ne
Vehicles with f lexible fuel engines may be op­
erated with bio-ethanol fuels such as E85 (85% ethano
l and 15% gasoline) or with un­
leaded gasoline (91 AKI/ROZ 95). The vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption wi ll increase when us­
ing bio-ethano l fue ls due to the lower amount
of energy contained per unit volume in etha­
nol.
Warming up the Flexible fuel engine in
low temperatures
Due to the chemical composition of bio-etha­
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures . Th is fuel evaporates again
when the engine is warmed up.
II Please warm up engine.
If the driver message appears in the instru­
ment cluster disp lay, drive with a warm en­
gine to reduce the oil level.
CD Note
- Never fill with methanol or with a higher
percentage of bio-ethanol than 85%
(E85). A higher percentage of bio-etha­
nol in the fuel can cause damage to the
eng ine or to the fuel system .
- Read and follow the information and t ips
about gasoline¢
page 211.
Gasoline additives
A major concern among many auto manufac­
turers is carbon depos it build-up caused by
the type of gaso line you use .
Although gasoline grades differ from one manufacturer to another, they have certain
th ings in common . All gasol ine grades conta in
substances that can cause deposits to collect
on vital engine parts, such as fue l injectors
and intake valves. A lthough most gasoline
brands include add itives to keep engine and
f uel systems clean, they are not equally effec­
tive .
Audi recommends using TOP TIER Detergent
Gasoline . For mo re information on TOP TIER .,.

214 Fuel supply and filling your fuel tank
Refuelling procedure
.. Inse rt the fue l nozzle from the gasol ine
pump into the fue l filler neck as far as it will
go.
.. Select a m edium refu elling rate so that the
no zzle switches
off automatica lly when the
tank is full.
Putting the fuel cap back on
.. After filling your tank, twist the fuel 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 cap properly and
comp letely.
A WARNING
Improper refueling or handling of fue l can
cause fire, explosion and severe burns.
- Fuel is highly f lammable 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 overflow ing fuel can
cause a fire .
- Never use a cellular telephone while re­
fueling . The electromagnetic radiation
can cause sparks that can ignite fue l va­
pors and cause a fire.
- Never get back into your vehicle while re­
fueling. If in exceptiona l circumstances
you must get back in your vehicle wh ile
refue ling, make certa in 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.
- For your safety, we strongly recommend that you do not travel w ith a portable
fuel container in your vehicle. The con- tainer, fu
ll or empty may leak and could
cause a fire, especially in a crash .
- If, under exceptional circumstances, you
must transport a portab le fuel container,
please observe the following:
- Never fill a portable fuel container
wh ile 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 fue l vapors causing a fire .
-Always place a portab le fue l container
on the ground before filling .
- Always keep the filler nozzle complete­
ly inside the portable container before
and during filling.
- If filling a portab le 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 spill fuel inside the vehicle or luggage compartment . Fuel vapors are
highly flammable .
- Always observe local and state/provin­
c ial 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 spi lled onto the car, it
should be removed immediately to prevent
damage to the paint.
@) For the sake of the environment
As soon as the correct ly operated nozzle
switches
off automat ically 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 wi ll be filled -causing the fuel to
overflow when it becomes warm and pol­
lute the environment.

Working in the engine compartment
Be especially careful whenever you work in
the engine compartment .
Whenever you must perform any wo rk in the
engine compartment, for example checking
and filling different fluids, th ere is a risk of
injury, burns and accidents. To prevent per­
sonal injury always observe the following
WARNINGS. The engine compartm ent of any
vehicle is a hazardous area

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
quires little attention .
The cooling system has been filled at the fac­
tory with a permanent coolant which does not
need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly ­
col-based coolant additive G13 antifreeze with
anticorrosion additives (50% for USA models;
60% for Canadian models). This mixture both
assures the necessary frost protection and
protects metal components in the engine's
cooling system from corrosion and scaling. It
also raises the boiling point of the coolant.
Do not reduce the concentration of the cool­
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 antifreeze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi­
cle heating and engine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31°F(-35 °C)USA
- -40 °F ( - 40 °C) Canada.
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS
¢ .&. in Working in the engine
compartment on page 216.
(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 especially impor­
tant if you live in a region where the win­
ter is extremely cold. If necessary, in-
Checking and filling 223
crease the proportion of coolant additive
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 radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid 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.

Di sconn ecting the battery t erminal s
Some vehicle functions (power w indow regu­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connec ted again. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs .
Vehicl es not driven for long p eriod s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cu t back or switched off .
This reduces energy consumption and main ­
tains starting capability over a longer per iod

Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustment. The conven ience
functions will be ava ilable again whe n you
turn on the ignition and sta rt the eng ine.
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop . This
i s because more powe r is also consumed while
start ing , and the head lights, rea r window de­
fogger, etc., are used more often .

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tively small patch of rubber on each tire that
assures that a ll- important contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry more weight than they can safely han­
d le, avoiding damage from road hazards and
r eg ularly inspect ing t ires for damage i nclud­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separat ion and blowouts.
A vo idin g damage
If you have to drive over a curb or similar ob­
stacle, drive very slow ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chemicals includ ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
i nstall them .
When removed, the wheels or t ires should be
sto red in a cool, dry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims .
Tires an d wheel s 231
New tires
New ti res have to be broken in¢& .
The tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
patte rn.
H idden damage
Damage to tires and r ims is often not readily
visible . If you notice unusual v ib rat ion or the
vehicle pulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
ti res m ust be chec ked immed iate ly by an au­
thorized Audi dea le r or q ua lified wor kshop .
Unidirectional tires
A un idirectional tire can be identified by ar­
rows on the sidewa ll, that po int in the direc­
tion the t ire is designed to rotate. You must
f ol low the specified di rection of rotation . T his
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.
For more information ¢
page 258.
A WARNING
New tires or t ires that are o ld, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
also be broken-in. To reduce the risk of losing control, a collision and serious
personal injuries, drive w ith special care
for the first 350 miles (560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail­
ure, including a blowout and sudden de­
fl ation, cras hes and se riou s personal in­
juries . Have worn or damaged t ires re­
placed immediate ly.
- Tires age even if they are not being used
and can fai l sudden ly, especially at hig h
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at low
speed.

232 Tire s and wheel s
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
