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 175
fuel systems clean, they are 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
fuels, built-up carbon deposits can rob yo ur
engine of peak performance.

Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fille r flap.
If the unlocking system should fail, you can
still open the flap manually -for detailed in ­
structions see ¢
page 177.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢ page 239.
The label on the inside of the fuel fi ller flap
tells you the correct fue l for your vehicle. For
more information about fuel specifications,
see ¢
page 174.
Your vehicle fue l tank has an on -board refue l­
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 while protecting the environment,
please fo llow this refueling procedure careful­
ly.
_&. WARNING
Under normal operating conditions, never
carry additional fue l conta iners in yo ur car.
Gas canisters and other containers used to
transport f uel can be dangero us. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must

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 fuel tank
is completely dry. The irregular supply of
fuel can cause misfiring. Gasoline could
enter into the exhaust system and damage
the catalytic converter.
Refuelling
Fig. 132 Driver's door: Un locking fuel filler flap
Fig. 133 Fuel cap hooked on the opened fue l filler flap
When adding fue l, the ignition and any ce llu­
lar phones in the vehicle must be switched
off .
Taking the fuel cap off
• To open the fuel filler flap, pull the button
9fig. 132.
• Unscrew fuel filler cap counter-clockwise
and hang it on the fuel filter flap¢
fig. 133 .
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 filter
cap clockwise until you hear a definite click.
• Close the fuel filler flap.
To avoid fuel spilling or evaporating from the
fuel tank always close fuel filler cap properly and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp¢
page 28
to come on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fue l 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 filter neck could cause
fuel 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
fueling. The electromagnetic 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 fuel container.

-For your safety, we strongly recommend
that you do not travel with a portable
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 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 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
cial 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 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
lute the environment.
a) Tips
- Running your engine while refuelling
may cause vapors to escape or even fuel
to spill out of the tank. This would then
shut off the fuel nozzle before the tank
is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may
otherwise not indicate the correct fuel
level after refuelling.
Unlocking the fuel filler flap
by hand
You can open the fuel filler flap by hand if the
power locking system should fail .

- Remove the igni tion key.

186 Checking and filling
Before you check anything in the engine com­
partment,
alwa ys r ea d and heed all WARN­
INGS ¢ A in Working in the engine
comportment on page 178.
• Switch the ignition off .
• Read the coo lant level at the coolant expan­
s ion tank ¢
fig. 141 . With a co ld engine, it
must be above the "min" mark. W ith a hot
engine, it can be a little above the indicated
range.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration .
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 ¢
page 31 will
blink until you add coo lant and the level has
been restored to no rma l. Even though there is
an electric coolant level sen sor, we still rec­
ommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system . In the event of coolant loss, the cool­
ing system should be inspected immediately
by your authorized A udi dealer. It is not
enough merely to add coolant .
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
@ Note
Do not add any type of ra diator leak seal­
ant to yo ur vehicle's eng ine coolant. Add ­
ing radiator repair f luid may adversely af­
fect the function and performance of your
cooling system and could result in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the engine com­
partment,
always read and heed all WARN­
INGS ¢ A in Working in the engine comport­
ment on page 178 .
•Turnoff the engine.

188 Checking and filling
If the brake fluid level falls considerably be ­
l ow the "MIN" mark, the brake warning/indi­
cator light (U .S . mode ls: . , Canadian
models: .) will come on
¢ page 16 and
¢ page 30. Do not continue to operate the ve­
h icle . The complete brake system shou ld be
thoroughly checked by an authorized A ud i
dea ler o r othe r qualified facility and t he cause
corrected. If the bra ke fluid level is too low,
the bra ke warning/ind ic a tor ligh t will illum i­
nate . Contact an authorized Aud i dea ler

Changing brake fluid
Hove the broke fluid changed by on experi­
enced technician.
B rake fl uid abso rbs mois ture from the a ir. If
the water content in the b ra ke fluid i s too
h igh, corros ion in the brake sys tem may result
after a period of t ime . The boi ling point o f the
b rake fluid wi ll also decrease considerab ly and
decrease braking per formance.
T herefore, the brake flu id mus t be changed
every two year s. Always use new b rake fluid
which conforms to Fede ral Motor Vehicle
Standard "FMVSS 116 DOT 4".
T he brake flu id rese rvoi r can be difficul t to
reach, therefo re, we recommend that yo u
have the brake f luid changed by yo ur autho r­
ized
Audi dealer . Your dealer has the correct
too ls, the right b rake f luid and the know-how
to do this for you.
A WARNING
- B rake fluid is poiso nous . It mus t be stor­

- Brake fa ilure can result from old o r inap ­
propriate b ra ke fluid. Observe these pre­
c aut ions:
- Use o nly brake fluid t hat meets SAE
specif ication
J 1703 and confo rms to
Federal Motor Vehicle Standard 116.
Always check with your a uthorized Audi
dealer to make s ure you are using the
correct brake fl uid. T he correct type of brake flu
id is also ind icate d on the
brake f lu id rese rvoir.
- The brake fl uid must be new . Heavy use
of the brakes can cause a vapo r lock if
the brake fluid is left in the system too

Battery
General information
Your ve hicl e is equipped with a specia l bat ­
tery, an
ACM battery. This battery is located
in t he luggage compartment and must be re­
placed with an origina l equipment battery.
U nder normal opera ting condit ions, the bat­
te ry is
maintenance-fr ee .
Have the battery checked when you take your
vehicle in for se rv ice . You a re well advised to
replace a battery that is o lde r th an 5 years .
Disconnecting the battery terminals
Some vehicle functions (power window reg u­
lators, for example) are lost if the battery te r­
mina ls are disconnected. T hese functions have
to be relearned after the battery termina ls are
connected aga in . T o prevent t his, t he battery
shou ld only b e disconne cted from the ve hicle
ele ct ric al sy stem w hen abso lutely ne cessary

Vehicles not driven for long periods
If you are go ing to let your vehicle stand for a
long time a nd not drive it, you should remem­
ber there are elect rical components which a re
Ill-

Never exceed the m aximum inflati on pres­
s u re li sted on the ti re sidew all for any rea­
son.
Remembe r that the vehicle manufacturer, not
the t ire manufacturer, determines the co rrect
tire pressure for the tires on your vehicle.
It is importan t to check the tire pressure when
t he t ires are cold .
- Read the requ ired ti re pressure from the tire
pressure label located on d river's s ide B-pi l­
l ar .
- T urn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressure gauge on the valve .
- The tire pressures should only be checked
and adjusted when the tires are cold . The
s li ght ly raised p ressures of warm tires must
not be reduced.
- Adjust the t ire pressure to the load you a re
ca rrying.
- Re install the valve stem cap on the valve .
When should I ch eck the ti re pres sur e?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and a lways before start ing a journey .
When should I ad just th e tir e pre ss ures?
Ad just the tire pressure to the load you are
carrying . After changing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition, you must then in it i­
alize the new tire pressures in the tire pres ­
sure mon itor ing system
q page 212 .
A WARNING
Incorrect tire pressures and/or unde rinfla­
tion can lead sudden tire failure, loss of cont ro l, col lision, ser ious persona l inju ry
or even death.
- When the warning symbo l
[D] appears in
the instrument cl uster, stop and inspect
the tires.
- Incor rect tire pressure and/or underinfla­
tion can cause increased tire wear and
Tire s an d wheel s 201
can affect the handling of the vehicle and
stopping ability .
- Incorrect tire pressures and/or underin­
flation can a lso lead to sudden t ire fail­
ure, including a blowout and sudden de­
flation, caus ing loss of veh icle control.
- The driver is responsible for the correct
tire pressures for all tires on the veh icle.
The applicable pressure values are locat­ ed on a sticker on the dr iver's s ide B-pil ­
lar .
- On ly when all tires on the vehicle are fil­
led to the correct pressure, the t ire p res­
sure mon itor ing system can work cor­
rectly.
- The use of incorrect tire p ressu re va lues
can lead to acc idents or other damage.
Therefore it is essential that the drive r
observe the spec ified t ire p ress ure val ues
for the t ires and the correct pressures for
the function of the tire press ure monito r­
ing system.
-A lways inflate tires to the recommended
and correct tire pressure before dr iv ing
off.
- Driving with underinf lated tires bend
mo re, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/over loading can
cause heat b uild-up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have
to change a wheel immediately, drive at
reduced speed to the nearest service sta­
tion to check the t ire p ressu re and add
a ir as requ ired.
(D Note
Driving w it h out valve stem caps can cause
damage to the tire valves. To prevent this,
always make sure that factory installed
valve stem caps on all whee ls are secu rely
mounted o n the valve. .,.

& WARNING
- Using incorrect or unmatched tires and/
or whee ls or improper tire and whee l
combinations can lead to loss of contro l,
collision and serious personal injury.
- Always use tires, rims and wheel bo lts
that meet the specifications of orig inal
factory-installed tires or other combina­
t ions that have been spec ifically ap­
proved by the vehicle manufacturer .
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . T ires that are more than 6 years
o ld can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used ti res on you r vehicle if
yo u are not s ure 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.
- All four wheels must be fitted with radia l
t ires of the same type, size (roll ing cir­
cumference) and the same tread pattern .
Driv ing with different tires reduces veh i-
Tire s an d wheel s 207
cle handling and can lead to a loss of
contro l.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for examp le w ith winter t ires -only use
the spare t i re for a short period of time
and drive with extra care . Refit the nor ­
mal road wheel as soon as safely poss i­
ble .
- Never drive faster than the max imum
speed for which the tires on your vehicle
are rated because tires that are dr iven
faster than their rated speed can fa il
suddenly.
- Ove rloading tires cause heat build-up,
sudden tire fa ilure, including a blowout
and sudden deflation and loss of contro l.
- Temperature grades apply to tires tha t
are properly infla ted and not over or un­
derinf lated .
- For technical reasons it is not always
possible to use whee ls from other vehi­
cles -in some cases not even wheels
from the same ve hicle mode l.
-If you install wheel trim discs on the ve ­
hicle wheels, make sure that the air flow
to the brakes is not b locked. Reduced air­
f low to the brakes can them to overheat,
increas ing stopping d istances and caus­
ing a co llision .
- Run flat tires may only be used on vehi­
cles that were equ ipped w ith them at the
factory. The veh icle must have a chassis
des igned for run flat ti res and a factory­
installed t ire p ressure monito ring sys­
tem that indicates a loss of ti re p ressu re.
I nco rrec t use of run fl at tires can lead to
veh icle damage o r accidents. Check with
an authorized Audi dealer or tire special­ ist to see if your vehicle can be equipped
with run flat tires. If run flat tires are used, they must be installed on all four
wheels. Mixing tire types is not permit-
ted .
