162 Fuel supply and filling your fuel tank
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.
@ 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 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 i ts 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 fue l 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.
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 diffe r from one
manufac turer 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 systems clean, they are not equally effec­
tive. Audi 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 your engine of peak performance.
(D Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the unlocking system should fail, you can
still open the flap manually -for detailed in­
structions see
~ page 164.
You can find the fuel tank capacity of your ve­
hicle in~
page 224 .
The label on the inside of the fuel filler flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see
~ page 161 .
Your vehicle fuel tank has an on-board refuel­
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 while protecting the environment,
please follow this refueling procedure careful­
ly.
.&_ WARNING ~
Under normal operating conditions, never
carry additional fuel containers in your 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 fuel to use for your lawn mower, ..,.

snow blower, etc., be very careful and al­
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 F8S2 -86).
(D Note
Never drive your vehicle unti l the fuel tank
is completely dry. The irregular supply of
fue l can cause misfir ing. Gasoline cou ld
enter into the exhaust system and damage
the cata lytic conve rter.

Refuelling procedure
.,. Insert the fuel nozzle from the g asoline
pump into the fuel fi ller neck as far as it wi ll
go .
.,. Select a med ium refuelling rate so that the
nozz le switches off automatically when the
tank is full.
Putting the fuel cap bac k on
.,. After fi lling your tank, twist the fuel filler
cap clockwise until you hear a definite click.
.,. Close the fue l filler flap.
T o avoid fuel spill ing or evaporating from the
fuel tank always close fuel filler cap proper ly
and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp¢
page 30
to come on.
A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fue l 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 o ut 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 iat ion
can cause sp arks that can ignite fuel va­
pors and cause a fire.
- Never get back into yo ur vehicle while re­
fue ling.
If in excep tional circumstances
you must get back in your vehicle while ref ueling, 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 refue ling.
- Never smoke or have an open flame any­
where in or near your veh icle when refu­
eling or filling a portab le fuel conta iner.
- For your safety, we strongly recommend
that you do not t ravel with a portable

164 Fuel suppl y and filli ng your fuel t ank
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 po rtable fuel conta iner
while it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the tr unk). Static electrici­
ty can bui ld up while filling and can ig­
n ite fuel vapors causing a fire .
- Always place a po rtable fuel container
on the ground before filling.
- Always keep the f iller nozzle complete­
l y inside the portable container before
and d uring fi lling.
- If filling a portable container made of
metal, the filler nozz le must always be
in contact with the container. Th is w ill
he lp prevent static electricity from dis­
charging and cause a fi re .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are
h ighly flammable.
- Always observe local and state/provi n­
cial laws regarding the use, storage
and transporta tion of fuel conta iners.
- 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 immediate ly 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 fue l because fuel may spill out. In
add it ion, the expans ion space in the fuel
tank will be fi lled -causing the fue l to
overflow whe n it becomes warm and pol­
lute the env ironment.
(D Tips
- Running your engine whi le refue lling
may cause vapors to escape or even fuel
to spill out of the tank. This would then
shut off the fuel nozz le before the tank
is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may otherwise not ind icate the correct fue l
level after ref uelling .
Unlocking the fuel filler flap

page 17 will
illum inate until you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level sensor, we
still recommend you check the coolant leve l
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool­
i ng system should be inspected immediately
Checkin g and fillin g 173
by your authorized Audi dea ler . It is not
enough merely to add coo lant .
In a
s ealed system, losses can o ccu r on ly if
the boiling point o f the coo lant is exceeded as
a res ult of overheating.
(D Note
Do not ad d any type of radiator leak sea l­

.&_ WARNING
-The coo ling system is under pressure and
can get
very hot. Reduce the risk of
sca lding from hot coolant by following
these steps .
- Turn off the eng ine and a llow it to cool
down.
- Protec t your face, hands and arms from
escap ing fl uid and steam by cover ing
the cap with a large, thick rag.
- Tu rn the cap slowly and
very ca refully
in a counter -clockwise direct ion while
applying light, downward p ress ure on
the top of the cap.
- To avo id being burned, do not sp ill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glyco l in en­
g ine coolant can catch fire.
- Antifreeze is poisonous. Always store an ­
t ifreeze in its or iginal container and we ll
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
ta iner clearly marked "poison".
(D Note
- Coolant po llutes the environment and
could cause an engine fire. Excess cool­
ant will be forced out through the pres­
sure re lief
valve in the cap when the en­
gine becomes hot .
- If, in an emergency, only water can be
added, the correct ratio between wate r
and antifreeze~
page 172 must be re­
stored as soon as possib le.
@) For the sake of the environment
Dra ined coolant should not be reused. Al­
ways dispose of used coolant while obse rv­
ing all environmental regulations .
Radiator fan
The radiator fan switches on automatically by
itself .
The electric radiator fan is controlled by ther­
moswitches that switch on and off depending
on coolant and eng ine compartment tempera­
tures.
An a uxiliary electric radiator fan* sw itches on
and off depending on coolant temperature
and other vehicle operat ion conditions .
After you switch the engine off, the aux iliary
fan can continue running for up to 10 minutes
-even w ith the ignition off. It can even switc h

188 Tire s and wheel s
forget the spare tire. If the pressure in any tire
is too high when the tire is "cold," let air out
of the tire slowly with the edge of the tire
ga uge and keep checking the pressure until
you reach the pressure that is correct for the
load (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the
d ifference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your veh icle as listed on the on
your ve hicle and in this manua l and the kind
of dr iving you p lan to do .
Never exc eed th e maximum inflati on pres­
sure listed on th e tir e s idewall for any rea ­
s on.
Remembe r that the vehicle manufacturer, not
the t ire manufactu rer, determ ines the correct
tire pressure for the t ires on your vehicle.
It is important to check the tire pressure when
the t ires a re cold .
- Read the requ ired tire press ure from the tire
pressure label located on driver's side B-pil­
lar .
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve.
- The tire pressures sho uld only be checked
and adjusted when the tires are cold. The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the valve stem cap on the valve.
Wh en should I check the tir e pr essure?
The correct tire pressure is espe cially impor ­
tant at high speeds . The pressure should
therefore be checked at least once a month
and a lways before starting a journey.
When should I ad ju st the tire pressures?
Adj ust the t ire p ressu re to the load yo u are
carry ing . After changing a wheel
or replacing whee
ls you have to adjust the tire p ressures
o n all whee ls. In addition, yo u m ust then initi­
alize the new tire press ures in the t ire pres­
s u re monitoring system¢
page 199.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious pe rsonal injury
or even death.
- When the warn ing symbol
RI] appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wea r and
can affect the handling of the vehicle and
s topping ability.
- I nco rrect tire pressures and/or underin­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout and su dden de­
flation, ca using loss of veh icle cont ro l.
- The drive r is responsible for the co rrec t
tire pressures for all tires on the veh icle .
The applicable pressure values are loca t­
ed on a sticker on the driver's side B -pil­
lar.
- On ly when all tires on the vehicle are fil­
led to the correct pressu re, the tire pres­
sure mon itor ing system can work cor­
rectly.
- The use of incorrect tire pressu re va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re p ress ure monito r­
ing system.
- Always inf late tires to the recommended
and correct t ire pressure before dr iv ing
off.
- Driving with unde rinf lated tires bend
mo re, letting them get too hot resulting
in tre ad separation, sudden tire failure
and loss of cont ro l.
- Excessive speed and/overloading can
cause heat b uild- up, sudden tire failure
and loss of cont ro l.

Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires -only use
the spare tire for a short period of time
and drive with extra care. Refit the nor­
mal road wheel as soon as safely possi­
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un­
deri nflated.
- For technical reasons it is not always
possible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air­
flow to the brakes can them to overheat, increasing stopping distances and caus­
ing a collision.
- Run flat tires may only be used on
vehicles that were equipped with them
at the factory . The vehicle must have a
chassis designed for run flat tires and a
factory-installed tire pressure monitor­ ing system that indicates a loss of tire
pressure. Incorrect use of run flat tires
can lead to vehicle damage or accidents.
Check with an authorized Audi dealer or
tire specialist 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
permitted .
Tires and wheels 195
@ Note
-For technical reasons, it is not generally
possible to use the wheel rims from oth­
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged.
(® For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
¢ page 192,
fig. 142 .
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder­
al Safety Requirements in addition to these
grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
For example, a tire graded 1S0 would wear
one and one half (1 1/2) times as well on the
government course as a tire graded 100. •

was manufactured. Please see c> page 193,
Speed rating (letter code)
for a listing of the
speed rat ing letter codes and the maximum
speed at which the tires can be driven .
The speed rating letter code
( c> page 184) is
on the side wall of the tire
c::> page 192 .
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed. Always know the maximum
speed before driving off . Never drive faster
than the speed permitted for your specific
w inte r tires . This will cause damage to the
tires leading to an acc ident and serious
personal injury to you and yo ur passen­
gers .
A WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire fai lure in­
cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immed iately.
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for
wh ich the winter or other tires installed
on your vehicle are rated .
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winte r tires and all-whee l
drive tempt you into taking extra r is k s . A l­
ways remember:
- When brak ing, an a ll-wheel drive vehicle
hand les in the same way as a front drive
vehicle.
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice conditions.
Tire s an d wheel s 197
@) For the sake of the env ironment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow cha ins may be fitted only to the front
wheels, and only to certain tire sizes . Ask your
authorized Aud i dealer on which tire sizes
snow chains can be used .
If you are go ing to use snow chains, then you
must install them on the front wheels at
least .
The snow chains mus t have low-prof ile links
and must not be th icker than 0 .53 inch
