-The relevant safety requirements must be
observed when the vehicle or components
of the system are scrapped. A qualified
dealership is familiar with these regulations
and will be pleased to pass on the informa­
tion
to you.
-
Be sure to observe all safety, environmental
and other regulations if the vehicle or indi­
vidual
parts of the system, particularly the
safety belt or airbag, are to be disposed. We
recommend you have your authorized Audi
dealer perform this service for you.
Service and disposal of safety belt preten ­
sioner
The safety be lt pretensioners are parts of the
safety belts on your Audi. Installing, removing,
servicing
or repairing of belt pretensioners can
damage the safety belt system and prevent it
from working correctly in a collision .
There
are some important things you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
-
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and
death by preventing a safety belt preten­
sioner from activating when needed or acti­
vating it unexpectedly:
-
The belt pretensioner system can be activat­
ed only once.
If belt pretensioners have
been activated, the system must be re­
placed.
- Never repair, adjust,
or change any parts of
the safety belt system.
-Safety belt systems including safety belt
pretensioners cannot be repaired. Special
procedures are required for removal, instal­
lation and disposal of this system.
-For any work on the safety belt system, we
strongly recommend that you see your au­
thorized Audi dealer or qualified technician
who has an Audi approved repair manual,
training and special equipment necessary .

A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly:
- 1
-Never cover, obstruct, or change the steer­
ing wheel horn pad or airbag cover or the in­
strument panel or modify them in any way.
- Never
attach any objects such as cup holders
or telephone mountings to the surfaces cov­
ering
the airbag units.
- For cleaning
the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened with plain water. Solvents or cleaners
could damage the airbag cover or change
the stiffness or strength of the material so
that the airbag cannot deploy and protect
properly.
- Never repair,
adjust, or change any parts of
the airbag system.
-All work on the steering wheel, instrument
panel, front seats or electrical system (in­
cluding
the installation of audio equipment,
cellular telephones and CB radios, etc.)
must be performed by a qualified technician
who has the training and special equipment
necessary.
- For any work on
the airbag system, we
strongly recommend that you see your au­
thorized Audi dealer or qualified workshop.
- Never modify
the front bumper or parts of
the vehicle body.
- Always
make sure that the side airbag can
inflate without interference:
- Never install
seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi.
- Never
use additional seat cushions that
cover the areas where the side airbags in­
flate.
Airbag system
-Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi­
ately by an authorized Audi dealer.
-The airbag system can deploy only once. Af­
ter an airbag has been deployed, it must be
replaced with new replacement parts de­
signed and approved especially for your
Audi
model version. Replacement of com­
plete airbag systems or airbag components
must be performed by qualified workshops
only. Make sure that any airbag service ac­
tion is
entered in your Audi Warranty &
Maintenance booklet under AIRBAG RE­
PLACEMENT RECORD.
-For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit
interrupter.
-Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
technicians who have
the experience, in­
formation and special tools necessary to
perform the work safely.
-
If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed.

-If you a re unable to determine whether or
not a particular fuel blend
meets the speci­
fications, ask your service station or its fuel
supplier.
-
Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from
the use of fuels differ­
ent from those specified are not the respon­
sibility 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 problems 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 manufactur­
ers
is carbon deposit build-up caused by the type
of gasoline
you use .
Although gasoline grades differ from one manu­
facturer
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.
Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas­
oline.
For more information on TOP TIER Deter­
gent Gasoline, please go to the official website
(www.toptiergas .com).
After an extended period
of using inadequate
fuels, carbon deposit build-ups can rob your en­
gine of peak performance.

Damage or malfunction due to poor fuel qual­
ity
is not covered by the Audi New Vehicle
Limited Warranty.

Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind
the fuel filler flap.
If the power locking system should fail, you can
still open
the flap manually -for detailed instruc­
tions see
~page 235.
You can find the fuel tank capacity of your vehicle
in ~page 299.
The label on the inside of the fuel filler flap tells
you
the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
~page 231.
Your vehicle fuel tank has an on board refuelling
vapor recovery system. This feature helps to pre­
vent 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 carefully.
.&. WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous. Such containers,
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 always observe local and
state laws regarding the use, transportation
and storage of such fuel containers.
Make cer­
tain the container
meets industry standards
(ANSI/ASTM F8S2 -86).
{[) Note
Never drive your vehicle until the fuel tank is
completely empty. The irregular supply
of
fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

explos ive and increases the risk of serious
injury or death.
- Follow legal requirements when using,
storing and transporting fuel containers.
-Make sure the fuel container conforms to
industry standards (ANSI/ASTM F852-86).
CD Note
- Remove any overflowing fuel from the vehi­
cle
paint immediately.
- Never drive
until the fuel tank is completely
empty. The irregular supply of fuel that re­
sults from that can cause engine misfires.
Uncombusted
fuel will enter the exha ust
system and increase the risk of damage to
the catalytic converter.
@ For the sake of the environment
If the fuel nozzle is used correctly, it will indi­
cate that the tank is full the first time it
switches off automatically. Do not try to add
more fuel, because it can spill over. Also, the
expansion space in the tank will fill, which can
result in fuel spilling out when it becomes
warm and polluting the environment.
Tips
If adverse weather conditions cause the fuel
filler door to freeze shut, press on the center
of the filler door with the heel of your hand
and then try opening it again.
(0 Tips
-If the engine is running while fueling, va­
pors
can escape or the fuel can spill over.
Because
of this, the fuel nozzle switches off
before the tank is full.
-
Do not fuel the vehicle when the ignition is
switched on. Otherwise, the fuel gauge may
not show the correct level after fueling the
vehicle.
- Your vehicle
is equipped with a misfueling
guard.
It allows the vehicle to be fueled on­
ly with the correct fuel pump nozzle.
- A worn
or damaged nozzle or a nozzle that
is too small may not be able to open the
diesel misfueling protector. If this is the
234
case, try turning the nozzle before inserting
it in the fuel filler neck, use a different fuel
pump or see an authorized Audi dealer or
authorized Audi Service Facility for assis­
tance.
-The misfueling guard does not open when
adding fuel from a fuel container. When re­
fueling with a reserve canister, you
must
use the funnel stored in the luggage com­
partment qpoge 234, fig. 179.

Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure
that your vehicle is running in on
environmentally sound manner.
.,.. Always use lead-free gasoline Q page 231, Gas­
oline grade .
.. Never run the tank down all the way to empty.
.. Never put too m uch motor oil in your engine
Q page 240, Adding engine oil "t::r..
.. Never try to push-or tow-start your vehicle.
The
catal ytic converter is an efficient "clean-up"
device built into the exhaust system of the vehi­
cle. The catalytic
converter burns many of the
pollutants in the exhaust gas before they are re­
leased into
the atmosphere .
Checking and Filling
The exclusive use of unleaded fuel is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
f= - I
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never
touch the exhaust tail pipes once they
have become hot. This could result in burns.
-Do not park or operate the vehicle in a reas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or
other material which can cause a fire .
-
Do not appl y additional undercoating or
r ustproofing on or near the exhaust mani­
fold, exhau
st pipes, catalytic converter or
heat shields. During driving, the substance
used for un dercoating could overheat and
cause a fire.
CD Note
-Be aware that just one tank filli ng with
leaded fuel w ill already seriously degrade
the performance of th e c atalytic converter .
-
Do not exceed the correct engine oil leve l
Qpoge240 .
-Do not drive until the fuel tank becomes
completely empty. The engi ne could mis­
fire. Unbu r
ned fuel coul d also get into the
exhaust system and this could cause the
ca ta lyt ic co nver ter to overheat.
-Do not swi tch off the ignition whil e the vehi ­
cl e is moving .
-
Do not continue to operate your vehi cle un­
der these condi tions, as o therwise fuel c a n

Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled
with a high-quality oil
which
can usually be used throughout the entire
year.
CD Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet.
-
Use only a high quality engine oil that ex-
pressly complies
with the Audi oil quality
standard specified for your vehicle's engine.
Using any other oil can cause serious engine
damage.
-
Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en­
gine damage.
Tips
If you need to add oil and there is none availa­
ble
that meets the Audi oil quality standard
your engi
ne requires, you may add a tota l of
no more than O.S qt/l of a high-quality "syn­
thetic" oil that meets the following spec ifica­
tions.

Engine oil consumption
The engine in your vehicle depends on an ade­
quate
amount of oil to lubricate and cool all of
its moving parts.
In order to provide effective lubrication and cool­
i ng
of internal engine components, all internal
combustion engines consume a certa in amount
of oil. Oil consumption varies from engine to en­
gine and may change significantly over
the life of
the engine. Typically, engines with a specified
break-in period
(see~ page 56) consume more
oil during the break-in period than they consume
after oil consumption has stabilized.
Under normal cond it ions, the rate of oil con­
s u
mption depends on th e qu ality and viscos ity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient tem­
perature and road conditions. Further factors are
the amount of oil dilution from water condensa­
tion or fuel residue and the oxidation level of the
oil. As any engine is subject to wear as mileage
builds
up, the oil consumption may increase over
t ime
until replacement of worn components may
become necessary.
With all these variab les coming into play, no
standard rate
of oil consumption can be estab­
lished
or specified. There is no alternative to reg­
ular and frequent checking of the oil level, see
Note .
If the yellow engine oil level warning symbol II
in the instrument cluster lights up, you should
check
the oil level as soon as possible
~page 240. Top off the oil at your earliest con-
venience

-When adding oil, do not let oil drip onto hot
engine components. Th ere could be risk of a
fire.
-
You must secure the cap on the oil filler
opening correctly so that oil does not leak
out onto the hot engine and exhaust system
when the engine is r unning, because this is
a fire
hazard.
- Always clean skin thoroughly if it comes into
co ntact with engine oil.
«I) Note
-The oil level must not be above the@
range, because this can cause damage to
the catalytic converter or the engi ne. Con­
tact an authorized Audi dealer or authorized
A udi Service Facility to have excess oil ex­
tracted if necessary.
-
Do no t mix any additional lu bricants into
the engine oil. Damage cause by such addi­
tives is not covered by the warranty.
@ For the sake of the environment
-Oil should never enter the sewer system or
come into contact with the ground.

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service
sta­
tion.
Before you check anything in the engine compart­
ment, alwa y s read and heed all WARNINGS
~page236.
The engine oil must be changed accord ing to the
intervals specified i n your Warranty & Mainte­
nance booklet. This is very important be cause the

Coo Ling 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
q uires
little attention.
The cooling
system has been filled at the factory
with a
permanent coolant which does not need to
be changed. The coolant consists of a mixture of
specially conditioned water and the manufactur­
er's glycol-based coolant additive G13 antifreeze
with anticorrosion additives (50% for USA mod­
els; 60% for Canadian models). This mixture
both assures the necessary frost protection and
protects metal components in the engine's cool­
ing
system from corrosion and scaling. It also
raises
the boiling point of the coolant.
Do not reduce the concentrat ion of the coolant in
the summer by addi ng p la in water. The propor­
tion of coolant additive must be at least 50°/o
but not more than 60°/o to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
gine 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.
242
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled
water is recommended.
A WARNING
~ h . Before you check anything in t e engine com-
partment, always read and heed all WARN­
INGS C)page 236.
CD Note
-Before winter sets in, have the coo lant
checked to see if the coolant additive in you r
vehicle is
sufficient to meet the climate con­
d itions. This is especia l
ly important if you
live
in a regio n where the winter is extre m e­
ly cold . If necessary, increase the proportion
o f coo la
nt ad ditive to 60o/o.
-When add ing coolant additive to your cool­
ing
system, remember:
-We recommend using only coolant addi­
tive G12++
or G13 (check the label) for
your vehicle. This coolant additive is avail­
able at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The resulting
corrosion can cause a loss of coolant and
serious engine damage.
-Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra­
dia to r repair fluid may adversely
affect the
func tion and performance of your cooling
system and could result in damage not cov ­
ered by your New Veh icle Limited W arranty .

"" Close the cap securely .
A coolant loss suggests a leak. Immediately drive
your vehicle
to an authorized Audi dealer or au­
thorized
Audi Service Facility and have the cool­
ing system inspected.
If the cooling system is not
leaking, a loss can come from
the coolant boiling
through overheating and being pushed
out of the
cooling system.
.&. WARNING
-The cooling system is pressurized and can be-
come very hot.
To reduce the risk of burns
from hot coolant:
-
Do not open the coolant expansion tank cap
w ith
the engine hot. There is a risk of burns .
- Stop
the engine and allow it to cool.
-
Protect your face, hands and arms from es-
caping coolant and
steam by covering the
coolant tank cap with a large, thick cloth.
- Turn
the coolant tank cap counterclockwise
slowly and keep light pressure on
the cap.
-
To reduce the risk of burns, do not allow any
antifreeze or coolant to dr
ip onto the ex-
Checking and Filling
ha ust system or hot engine components.
The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- The coolant additive and the coolant can be
dangerous to your health.
For this reason,
keep
the coolant in the original container
away from children. There is a
risk of poi­
soning.
-When working in the engine compartment,
remember
that the radiator fan can switch

Radiator fan
The radiator fan switches on automatically by it­
self.
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch
the engine off, the auxiliary fan
can continue running for
up to 10 minutes -even
with
the ignit ion off. It can even switch on again
later by itself c:? & . if
- the temperature of
the engine coolant rises due
to
the heat build-up from the engine in the en­
gine compartment, or
-
the engi ne compartment heats up because the
vehicle is parked in intense sunlight.
.&. WARNING
-To reduce the risk of personal injury never
touch
the radiator fan.
- The auxiliary electric fan
is temperature
controlled and can switch on suddenly even
when
the engine is not running.
