A WARNING
-Forward-fac ing ch ild seats installed on the
front passenge r seat may inte rfere with the
deployment of the a irbag and cause serious
persona l injury to the child .
- If except ional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat , the child's safety
and well-being require the following special
precautions to be taken:
- Always make sure that the forward -facing
seat has been designed and cert ified by its
manufacture r fo r use on a front passenger
seat with a front and s ide a irbag.
- Always carefully follow the manufacturer's
instructions provided with the child seat
or i nfant car rier.
- Never p ut the fo rward-facing child re­
stra int up against o r very near the instru­
men t panel.
- Always move the front passenger seat to
the highest posit ion in the up and down
ad justment range and move it back to the
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible, before installing
the forward-facing ch ild restraint.
- Always make sure that the safety be lt up­
per anchorage is behind the child restra int
and not next to or in front of the child re­
stra int so that the safety belt will be prop­
erly positioned .
- Always make sure that nothing prevents
the front passenger's seat from be ing
moved to the rearmost posit ion in its fore
and aft adjustment range .
- Never place objects on the seat (such as a
laptop, CD p laye r, electronic games de­
vice, powe r inverter or seat heater for
child seats). These may influence the elec-
Ch ild safety
trical capacitance measu red by the capaci­
tive passenger detection system and can
also fly around in an accident and cause
serious personal injury.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, powe r inverter or seat heat ­
er for child seats) on the front passe nger
seat if the device is connected to the 12-
vo lt socket or the cigarette lighter soc ket.
- If a seat heate r has been retrofitted or
othe rw ise added to t he front passenger
seat, neve r insta ll any child res traint sys­
tem on this seat.
- Make su re that there a re no wet objects
(s uch as a we t towe l) and no w ater or ot h­
er liquids on the front passenger seat

Checking and Filling
-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.
(D Note
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 234.
You can find the fuel tank capacity of your vehicle in
~ page 291.
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.
.8, 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 F852 -86).
CI) 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.

Check ing and F illing
Using the proper engine oil is impo rtant for the
functionality and service life of the engine. Your engine was facto ry-filled with a h igh-quality oi l
which can usually be used throughout the entire
year.
@) Note
Your Limited New Vehicle War ranty 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 Warran ty
& Maintenance booklet.
- Use only a high quality eng ine oil t hat ex-
p ressly complies with the Audi oil qua lity
standard specified for your vehicle's engine .
Using a ny o ther oil can cause serious engine
d am age.
- D o not mix any lubricants o r other addit ives
i nto the engine oil. Doing so ca n cause en­
g ine damage.
(D Tips
I f you need to add oil and there is none availa­
ble t hat meets the Audi o il quality standard

Engine oil consumption
T he engine in your vehicle depends on an ade­
quate amoun t of oil to lubricate and cool all of
i ts moving par ts.
In order to p rovide effective lubr ication and cool­
ing of internal engine components, all interna l
combustion engines consume a cer tain amount
of oil. Oi l co nsumption varies from engine to en ­
g ine and may change significant ly over the life of
the eng ine . Typically, eng ines with a specified
238
b reak -in period (see q page 57) cons ume more
oi l during the break-in period than they consume
after o il consumption has stab ilized.
U nder normal cond itions, the ra te of oil con ­
s u mption depends on the q ua lity and viscos ity o f
the oil , the RPM (revo lutions per minute) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further facto rs a re
the amount of o il di lution from wate r condensa­
tion or fue l resid ue a nd the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the o il consumption may increase ove r
ti me until replacement o f wo rn components may
become ne cessary.
With a ll these va riables coming into p lay, no
standard rate of o il consumption can be estab­
li sh ed or spec ified . T he re is no alte rnative to reg­
u lar and freq uen t che cki ng of the oil level , see
Note .
If the yellow engine oil level warning symbo l l!I
in the instrument clus ter lights up , you sho uld

_& WARNING
Before you check a nyt hing in the en gine com ­
partment, always read and heed all WARN­
INGS
9 page 235.
@ Note
D riving w ith an insufficient oil level is like ly to
cause severe damage to the eng ine.
(D Tips
- The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
it . Instead, check the oil level in your en­
gine at regular intervals , preferably each
time you refuel, and always befo re going
on a long trip .
- If you have the impress io n your engine con­
sumes excessive amounts of oil, we recom­
mend that yo u consult an authorized A udi

,&. WARNING
i=
- When adding eng ine oi l, do not let oil drip
onto hot engine components. This increases
the risk of a fire.
- You must seal the cap on the oil filler open­
ing correctly so that oil does not leak out
onto the hot engine and exhaust system
when the engine is running, because this is
a fire hazard.
-Always clean skin thoroughly if it comes into
contact with eng ine oil.
(D Note
- The engine oil level must not be under the
ma rking
(D ¢ fig. 182, because th is increas­
es the risk of engine damage .
- After adding engine oil, the oil level must
not be above the marking @c>
fig. 182, be­
cause this increases the risk of catalytic con ­
verter and/or engine damage. Do not start the engine. Contact an authorized Audi
dea ler or authorized Audi Service Facility to
have excess engine oil extracted if necessa­
ry.
- Do not mix any additional lubricants into
the engine oil. Damage caused by such addi-
tives is not covered by the warranty. .,.

Checking and Filling
@ For the sake of the environment
-Engine oil should never enter the sewer sys­
tem or come into contact with the ground
under any circumstances.
- Pay attention to legal requirements when
disposing of empty oil containers.
(D Tips
The engine oil consumption may be up to 0.5 quart/600 miles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be higher during the
first 3,000 miles (5,000 km). Because of this,
the engine oil level must be checked regular­
ly .
It would be best to check each time you re­
fuel your vehicle and before long drives.
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, always read and heed all WARNINGS
q .&.
in Working in the engine compartment on
page 235.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet. This is very important because the
lubricating properties of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oil should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time. This is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
quired, we strongly recommend that you have
240
your oil changed by an authorized Audi dealer or
a qualified service station.
If you choose to change your oil yourself , please
note the following important information:
& WARNING
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
-
-To reduce the risk of burns from hot engine
oil, let the engine cool down to the touch.
- When removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the total amount of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine oil is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
(D Note
Never mix oil additives with your engine oil.
These additives can damage your engine and adversely affect your Audi Limited New Vehi­
cle Warranty.
@I For the sake of the environment
- Before changing your oil, first make sure
you know where you can properly dispose of
the used oil.
- Always dispose of used engine oil properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station .

Cooling system
Coolant
The engine cooling system is filled with a mixture
of pur ified water and coolant additive at the fac­
tory. This coo lant must not be not changed.
The coolant level is monitored through the. in­
dicator light
¢page 12. However , we do recom­
mend occasionally check ing the coo lant level
manually.
If you must add coolant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
Coolant additive
The coolant additive is made of anti-freez ing and
corros ion protection agents. Only use the follow­
ing coolant addit ives . These additives may be
mixed with each other.

and have the cooling 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.
A WARNING
The cooling system is pressurized and can be­
come very hot. To reduce the r isk of burns
from hot coolant:
- Do not open the coolant expansion tank cap when the eng ine is hot. This increases the
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 o n the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­ haust system or hot eng ine components .
T he ethylene glycol in eng ine coolant can
catch fire under certa in circumstances.
- The coo lant add itive and the coolant can be
dange rous to your health. For this reason,
keep the coolan t in the origina l container
and away from children. There is a risk of
poisoning.
- When working in the engine compartmen t,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of inj ury.
(D Note
Do not add coolant if the exp ansion tank is
empty . Air could enter the cooling system and
damage the engine . If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
