202 Fuel supply and filling your fuel tank
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 stations 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 flexible fuel en­
gines. Using high ethanol fuel in vehicles not equipped with flexible fuel engines
can cause severe engine damage.
- 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 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 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
lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Ethanol fuel (Bio -ethanol)
App lies to vehicles: with flexible fuel e ngi ne
You con recognize vehicles with a flexible fuel
engine by looking at the label on the inside of the fuel filler flap.
Vehicles with flexible fuel engines may be op­
erated with bio-ethanol fuels such as E85 (8S% ethanol 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 will increase when us­
ing bio-ethanol fuels 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 . This fuel evaporates again
when the engine is warmed up.
II Please warm up engine.
If the driver message appears in the instru­
ment cluster display, 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
engine or to the fuel system.
- If you use only E85, it is recommended
to fill the fuel tank completely with un­
leaded premium grade gasoline every
5,000 miles.
- If you experience starting, rough idle or
hesitation driveability problems, fill the
fuel tank completely with unleaded pre­ mium grade gasoline and drive it nor­
mally until the gasoline is used. See your
authorized Audi dealer if the problem
persists.
- Inform your authorized Audi dealer that
you are operating or have operated the
vehicle with E85.
- Read and follow the information and tips
about gasoline

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 specially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with anticorrosion addi­ tives (50% for USA models; 60% for Canadian 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 also raises the boil­
ing 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.
If you must add coolant, use a mixture of wa­
ter and coolant additive. Mixing the coolant
additive with distilled water is recommended.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢ .&.
in Working in the engine
compartment on page 206.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
Checking and filling 213
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
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.

Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by an authorized
Aud i dealer or qualified workshop . The elec­
trolyte leve l should also be checked each time
the battery is charged ¢
page 219.
Have the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a battery that is older than 5 yea rs .
W ith certa in types of a irbag deployment, t he
b attery is d isconnected from the vehicle elec­
tr ica l system for safety reasons¢.&.

pair, care and disposal of the airbags on
page 1 53.
Disconnecting the battery terminals
Some vehicle functions (power w indow regu­
lators , for example) are lost if the battery ter­
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
connected agai n. T o prevent this , the bat tery
should only be d isconnec ted from the vehicle
e lec tric al system when absolu tely necessa ry
for repairs .
Vehicles not driven for long periods
If you do not drive you r vehicle over a period
of severa l days or weeks, elec trical compo­
nen ts are gr adually cut b ack o r swi tched off .

problems w hen the weather is cold, but w ill
also last longer .
@ Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery s hou ld be removed and
stored where it will not freeze . This will
p revent it from be ing damaged and having
to be repla ced .

220 Check ing and filling
- To r educe the danger of explosion, never
co nnect or disconn ect cha rger cables
wh ile the c harger is operating.
- Fast char ging a battery is dangerous and
shou ld on ly be attempted by a compe­
tent technician w ith the proper equip­
ment .
- Battery acid that may spill d uring charg­
ing should be washed
off with a solution
of warm water and baking soda to neu ­
tralize the acid.
(Q) Note
Never use a fast charger as a booster to
start the engine . This will seriously dam­
age sensitive electronic components, such
as control units, relays, rad io, etc., as we ll
as the battery charger.
Battery replacement
The new battery must have the same specif/·
cations and dimensions as the original equip­
ment battery.
In tell igent energy management in your veh i­
cle is respons ible for d istributing the e lectr i­
cal energy throughout you r vehicle
~ page 185. The intell igen t energy m anage­
men t system w ill keep the engine ba tte ry
charged better then vehicles w ithout this sys­
tem . To make sure the additional e lectrica l en­
ergy is available once again after you have
changed the battery, we recommend that you install batteries o f the same type and ma nu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery hous ing. You r
author ized Audi dealer must code the battery
in the ene rgy managemen t system to enable
you to use the ene rgy management functions
correctly after replac ing the battery.
I f it is not poss ible to use a battery of this
type, the new bat tery m ust h ave the s ame ca­
pac ity, voltage ( 12-volts), amperage, con ­
struction and plug sea ling. When installing the battery, make su

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
tive ly small patch of rubber on each tire that
assures that a ll-impo rtant 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 mo re weight than they can safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
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.
Avoiding damage I f you have to drive over a curb or similar ob­
stacle, drive very s low ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chem ica ls includ ing gre ase, o il,
gasoline and b rake fluid off the ti res .
Inspect 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
install t hem.
When removed, the whee ls or t ires should be
stored in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on r ims, in a horizontal pos it ion if
they are mounted on rims. New tire
s
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is ofte n not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one s ide, th is may ind icate
t h at one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au ­
tho rized Aud i dea le r or q uali fied wor ks hop.
Unidirectional t ires
A un idirectional tire can be identified by ar­
rows on the s id ewa ll, that po int in the direc­
t ion the t ire is desig ned to rotate. You mus t
f ol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characterist ics regarding grip,
road no ise, wear and hyd rop laning resistance.
For more information
¢ page 249.
A WARNING
-New tires or tires 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 t he risk of
losing control, a collision and se rious
pe rsonal injuries, drive w it h specia l care
for the first 350 miles (560 km).
- Driving with worn or damaged tires can
le ad to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
fl ation, c rashes and seriou s personal in­
juries . Have wo rn or damaged t ires re­
p laced immediate ly .
- T ires age even if they are not being used
an d can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.
