174 Cleaning and protection
• Once the stain is no longer visib le, use a
soft dry cloth or tissue to soak up the mois ­
ture.
Do not use leather cleaning products on Al ­
cantara .
You may use a suitable shampoo fo r remov ing
d ust and dirt.
Dust and grit in the pores and seams can
scratch and damage the surface. If the ca r is
l eft standing i n the sun fo r long periods, the
A lcantara should be protected against direc t
sunlight to prevent it from fading. Slight co lor
variations will deve lop in normal use and are
not an indication of material deterioration.
{[) Note
-Never use chemical solvents (e.g . lighter
fl uid, turpentine), waxes, shoe polis h or
similar products on Alcantara ® surfaces.
- To avoid damage, have stubborn stains removed by a commercial cleaning spe­
cia list.
- Do not use br ushes, stiff sponges or sim­
ilarly abrasive cleaning aids.
Safety belts
Only well -maintained safety belts work relia ­
bly when needed .
Heavily soiled safety belts may no t retr act
p roperly.
• Keep be lts clean.
• Fo r cl eaning, use a m ild soap and wate r sol­
u tion. Let be lts dry thoro ughly and away
from direct sunlight .
• Do not a llow inertia reel safety be lts to re­
tract before they are completely dry .
• Check the condition of your safety belts
reg­
ularly.
.&_ WARNING
Damaged safety belts can break in a crash.
1l Use o nly the co rrect cleaning so lu tions. Never use gas­
o line or d iese l fue l.
-Anyth ing that might damage your safety
be lts could mean that you and your pas­
sengers would not be adequate ly pro­
tected in an accident.
- Safety belt performance depends on cor­
rect insta llation. Never remove be lts
from the veh icle to clean them .
- Do not use chemical clean ing agents,
b leach or dyes. They have co rrosive prop­
erties which wea ken the webb ing.
- When clean ing your safety be lts, inspect
them for damage . If you discover dam­
age, see your Audi dealer.
'
- Always read a nd heed all WARNINGS and
the information

Engine compartment
Be especially careful when cleaning the en­
gine comportment.
Alway s swit ch off the ign ition before clean­
ing the engine <=;>.&, .
Plenum panel
Remove leaves from the plenum panel in front
of the w indshield under the eng ine hood . This
prevents the water drain holes from becoming
blocked, and it prevents debris from enter ing
the vehicle interior t hro ugh the heating and
ventilat ion ducts.
Corrosion protection
T he engine compartment and transmission
have been corrosion -protected at the factory .
Good anti- corrosion treatmen t is very impor­
tant, particu larly in the w inter.
If the vehicle
is frequently driven on salt treated roads, the
entire engine compartment and p lenum panel
shou ld be thoroughly cleaned at the end of
winter and retreated to prevent salt damage.
At the same time, the underside of the vehicle
shou ld be washed as well.
If the engine compartment is cleaned at any
time with grease removing solutions
1>, or if ..,.

-Blend must contain not more than 15%
MTBE.
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 177
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more info rmation on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
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 179.
You can find the fuel tank capacity of your ve­ hicle in
Technical Data ¢ page 240.
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 176.
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 fuel containers in your car.
Gas canisters and other containers used to

A WARNING
Imp roper 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 .
- Fai lure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fu lly into the fuel filter neck could cause
fuel to spray out of filler neck or to ove r­
f low. Fuel spray and overflowing fuel can
cause a fire.
- Never use a ce llu lar telephone whil e re­
fue ling . Th e e lec tromagnet ic radiat io n
can cause spa rks th at can igni te fuel v a­
pors an d cause a fire.
- N ever get back in to your vehicle whi le re­
fue ling.
If in excep tio nal cir cumstances
you must get back in your vehi cle while
ref ueling, make ce rtain that you close
the door and touch metal to discharge
static electricity be fore touching the fill­
er nozzle again . Static e lectr icity can
cause sparks that can ignite fuel vapors
re leased d uring refueling .
- Never smoke or have an open f lame any­
where in or near your ve hicle when refu­
eling or fi lling a portable fue l conta iner .

-For your safety, we strongly recommend
that you do not trave l w ith a portab le
fuel container in your vehicle. The con­
tainer, full or empty may leak and cou ld
cause a fire, especially in a crash.
- If, under except ional circumstances, you
must transpo rt a portable fuel container,
please observe the following:
- Never f ill a portable fue l container
while it is anywhere in or on the vehicle (for examp le, in the luggage compart­
ment, or on the tr unk) . Static electric i­
ty can bu ild up while f illing and ca n ig­
n ite fuel vapors causing a f ire.
- Always place a portable fuel container
on the ground before filling .
-Always keep the fi ller nozzle comp lete­
ly inside the portable conta iner before
a nd during filling.
- If filling a portable container made of metal, the filler nozz le must always be
in contact with the containe r. 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/p rov in­
cial laws regard ing the us e, storage
and trans po rt ation of fuel con tainers.
- Make certa in the fuel conta iner meets
in du stry standards (ANSI/ ASTM
F8 52-86).
(D Note
If any fuel has spilled onto the ca r, it
should be remov ed immed iate ly to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correctly operated nozzle sw itches off automatically fo r the fi rs t
time, th e tank is full. Do not try to add
more fue l because fuel may spill ou t. In
a dd ition, the exp ansio n sp ace in the fuel

188 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 compart­
ment on page 180.
• Park your vehicle on a level surface.
• Switch the ignition off.
• Read the coolant level at the coolant expan­
s ion tank ¢
page 182, fig . 134. With a cold
engine, it must be above the "min" mark .
With a hot engine, it ca n be a little above
the indicated range .
The location of the coolant expans ion tank
can be seen in the engine compartment illus­
tration
¢ page 182.
To obtain an accurate read ing, the engine
must be switched off.
The expansion tank in yo ur vehicle is equipped
with an e lectric coolant level sensor .
When the coo lant level is too low, the warning
light in the A uto- Check System ¢
page 16 will
illuminate until yo u add coo lant and the level
has been restored to normal. Even though
there is an electric coo lant 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 cooling
system . In the event of coolant loss, the cool­
ing system should be inspected immediately
by your author ized Audi 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 overheat ing.
(D Note
Do not add any type of radiator lea k seal­
ant to your 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 res ult 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 compart­
ment on page 180 .
• Turn off the engine.
• Let the engine cool down.
• Place a thick rag over t he coo lant expansion
tank

190 Checking and filling
If the brake fluid level falls considerably b e­
l ow the "MIN" mark, the brake warning/ indi­
cator light (U .S . mode ls:
1111 , Canad ian
model s:. ) will come on
c> page 14 . Do not
continue to ope ra te the vehicle. The comple te
brake system shou ld be thoroughly checked
by an author ized Audi dealer or ot her quali­
fied fac ility and the cause corrected . If the
b rake fluid level is too low, the b rake war ning/
i ndicator ligh t w ill illuminate. Contact an a u­
thor ized A udi dealer
immediatel y.
Changing brake fluid
Hove the broke fluid changed by on experi­
enced technician.
Brake fl uid abso rbs moist ure from the a ir. If
the wate r content in the b ra ke fluid is too
h igh, cor ros ion in the br ake sys tem may result
after a per iod of t ime . The bo iling point of the
brake fluid wi ll also decrease considerab ly and
decrease braking performanc e.
Therefore, the brake fl uid mus t be changed
every tw o year s. Always use new b rake fluid
which conforms to Federal Motor Veh icle
Standard "FMVSS 1 16 DOT 4".
The brake flu id rese rvoi r can be difficul t to
r each, therefo re , we recommend that yo u
have the brake f luid changed by yo ur autho r­
ized
Audi dealer. Your dea ler has the correct
too ls , the right brake f luid and the know-how
to do this for you.
A WARNING
- Brake fluid is poiso nous . It must be stor­
ed only i n the closed orig inal container
o ut o f the reac h of children!
- Brake fa ilure can result from old o r inap ­
propriate b rake fluid . Observe these pre­
caut ions :
- Use only bra ke fluid that meets SAE
specif ication
J 1 703 and co nforms to
Federal Motor Vehicle Standard 116 .
Always check with your a uthori zed Audi
dealer to ma ke sure you are using the
correct brake flu id. The correct type of brake flu
id is also ind icate d on the
brake f lu id rese rvoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapo r lock if
the brake fluid is left in the system too
long. This can seriously affect the effi­
c iency of t he brakes as well as your
safety . T his co uld resu lt in a n accide nt.
([) Note
Brake fluid will damage the paint of your
vehicle.
@ For the sake of the environment
Because o f the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
required and the necessary expertise, we
recomme nd that you have the brake flu id
changed by yo ur autho rize d Aud i deale r.
Battery
General information
Your vehicle is equipped with a specia l bat ­
tery, an
ACM battery. This battery is located
in the 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 serv 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 again . T o p revent t his, t he battery
shou ld only be disconne cted from the veh icle
elect ric a l sys tem when abso lutely ne cessary
f or rep air s.
Vehicles not driven for long periods
If you do not drive your vehicle ove r a period
of seve ral days o r weeks , e lectr ica l compo-
nents a re g radually cut back or switched off.
Ill-

forget the spare tire. If the press ure in any tire
is too high when the tire is "cold," let air out
of the tire slowly with the edge of the t ire
gauge 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 a ir
that you need to reach the correct pressure for
the veh icle 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 exce ed the ma ximum inflation pres ­
s ur e listed on t he tire s idewall for any re a­
s on.
Remember that the vehicle manufacturer , not
the t ire manufacturer , determ ines the correct
tire pressure for the tires on your veh icle .
It is important to check the tire pressure when
the t ires a re cold .
- Read the req uired tire press ure from the tire
pressure label located on driver's s ide B-pil­
l ar .
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressure ga uge on the valve.
- The tire pressures sho uld on ly be checked
and adjusted when the tires are cold . The
s light ly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the va lve stem cap on the valve .
When should I check the tire pressure?
The correct tire pressure is espec ially impo r­
tant at high speeds . The pressure sho uld
therefore be checked at least once a month
and a lways befo re starting a journey.
When should I adjust the tire pressures?
Adj ust the tire pressu re to the load you are
carry ing . After changi ng a wheel
or replacing
Tire s an d wheel s 203
whee ls yo u have to adjust the ti re p ressu res
o n all whee ls. In addition, yo u m ust then initi­
a lize the new tire pressu res in the t ire pres­
s u re monitoring system
Q page 214.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serio us pe rsonal injury
or even death.
- When the warning symbol
[I] appears in
the instrument cluster, stop and inspect
the t ires.
- Inco rrect tire pressure and/or underinfla­
tion can cause increased tire wea r and
can affect the handling of the vehicle and
stopping ability.
- Inco rrect tire pressures and/or underin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and su dden de­
flation, ca using loss of veh icle cont ro l.
- Th e drive r is responsi ble for the correc t
tire pressures for all tires on the veh icle.
The applicable pressure values a re locat ­
ed on a sticke r on the dr iver's side B-pil­
lar.
- On ly when all tires on the vehicle are fil ­
led to the correct pressure, the t ire 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 th e ti r e p ressu re monito r­
ing system.
- Always inf late tires to the recommended
a nd correct t ire p ress ure before dr iv ing
off.
- Driving with unde rinflated tir es bend
mo re, letting t hem get too hot resulting
in tre ad separation, sudden tire f ailure
and loss of cont rol.
- Exces sive speed and/overloading can
cause he at bu ild- up, sudden tire failure
an d loss of cont rol. •
