Checking and Filling
Fuel supply
Applies to vehicles: with gasoline engine
Using the right fuel helps keep the environ
ment clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is un
leaded premium
grade gasoline . Audi recom
mends using TOP TIER Detergent Gasoline
with a minimum octane rating of 91 AKI (95
RON). For more information on TOP TIER De
tergent Gasoline, please go to the off icia l
website (www.toptiergas.com).
The recommended gasoline octane rating for
your engine can a lso be found on a label locat
ed on the inside of the fuel filler flap. This rat
ing may be specified as AKI or RON.
Your vehicle may also be operated using un leaded regular gasoline with a minimum oc
tane rating of
87 AKI/91 RON. However, using
87 AKI/91 RON octane fuel w ill slightly re
duce eng ine performance.
Use unleaded gasoline only. Unleaded gaso
line is available throughout the USA, Canada,
and in most European countries. We recom
mend that you do not take your vehicle to
areas or countries where unleaded gasoline
may not be ava ilable .
For more informat ion on refueling your vehi
cle, see
c:> page 211 .
Octane rating
Octane rating indicates a gasoline's ability to
res ist engine damaging "knock" caused by
premature ign ition and detonation. Therefore,
buying the correct grade of gasoline is very
important to help prevent possible engine
damage and a loss of engine performance .
Gasoline most commonly used in the United
States and Canada has the following octane
ratings that can usually be found on the filler
pump:
- Prem ium Grade : 91- 96 AKI -
Regular Grade:
87 -90 AKI
E xplanation of the abbreviations:
AK I=
Anti Knock Index = (R +M)/2 = (RON
+MON)/2
RON= Research Octane Number
MON = Motor Octane Number.
(D Note
- Do not use any fuel w ith octane rat ings
lower than
87 AK I or 91 RON otherwise
expensive engine damage will occur .
- Do
not us e leaded gasoline. The use of
leaded gasoline w ill severely damage
your vehicle's catalytic converter and its
ability to control exhaust emissions.
Blended gasoline
Applies to vehicles: with gasoline engine
Use of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether)
You may use unleaded gasoline blended with
alcohol or MTBE (commonly referred to as
oxygenates) if the blended mixture meets the
follow ing criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti -knock index must be 87 AKI or higher.
- Blend must contain no more than 3% meth-
anol.
- Blend must contain more than 2% co-sol -
vents .
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
-Anti-knock index must be 87 AKI or higher.
- Blend must not co nta in more than 15%
ethanol.
Blend of gasoline and MTBE
-Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
M N
" > co ,...., \!) ..,.,
,...., ..,., ,....,
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.
Q;) 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
specificat ions, ask your service station or
i ts 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
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 differ from one manufacturer to another, they have cer tain
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.
Checking and Filling 211
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, carbon deposit build-ups can rob your engine of peak performance.
CJ) 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 power locking system should fail, you
can still open the flap manually -for detailed
instructions see~
page 213.
You can find the fuel tank capacity of your ve
hicle in
~ page 280.
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 210 .
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 .
A 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

ASTM F852 -86) .
(D 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
catalyt ic converter.

A WARNING
Not paying attention when fueling or han
d ling fuel incorrect ly can lead to fires, ex
plosions or serious injuries.
- Fue l ignites easily and can cause serious
burns and other injuries.
- If you do not switch the engine off when
fue ling and/or do not insert the fuel noz
zle completely into the tank opening ,
fuel can leak out or run over. Leaked fuel can ignite and start a fire .
- Do not use the telephone while fueling.
The electromagnetic rays can cause
sparks, wh ich can ignite fuel vapors and
start a fire.
- Do not sit in your vehicle while fueling . If
you must make an exception and enter
your veh icle again while fueling, close
the door and touch metal to discharge
s tatic electricity before touching the fue l
nozz le . Static electricity can create
sparks, wh ich can ignite vapors when fu-
eling . .,._

-Do not smoke or have an open flame in
the area when fueling your vehicle or fill
ing a fuel container because this
increases the risk of an explosion .
- For your safety, carrying fuel containers
in your vehicle is recommended. Wheth
er full or empty, the container can leak
and cause a fire in the event of an acci
dent .
- If you must make an exception and
transport a fuel container, note the fol
lowing:
- Never f ill the fuel container with fuel
while it is in or on the vehicle. Static
electricity is discharged when filling
which can cause the fuel vapors to ig
nite and increases the risk of an explo
s10n .
- Always place a fuel container on the
ground before filling .
- Always hold the fuel nozzle completely
in the fuel container when filling.
- If the fuel container is made of metal,
the fuel nozzle must always be in con
tact with the container when filling it
with fuel. This prevents static electrici
ty from discharg ing.
- Never sp ill fuel in the vehicle or the
luggage compartment. Evaporated fuel
is exp losive and increases the risk of
serious injury or death .
- Follow legal requirements when using,
storing and transporting fuel contain
ers.
- Make sure the fuel container conforms
to indust ry standards (ANSI/ASTM
F852-86).
(D Note
-Remove spilled fuel from vehicle paint
immediately, because it can damage
paint.
- Never drive until the fuel tank is com
pletely empty. The irregular supply of
fuel that results from that can cause the
engine to misfire. Uncombusted fuel will
enter the exhaust system and increase
Checking and Filling 213
the risk of damage to the catalytic con
verter.
@ For the sake of the environment
- If the fuel nozzle is used correctly , it will
indicate 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.
(D 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 ign ition
is switched on . Otherwise, the fuel
gauge may not show the correct level af
ter fueling the vehicle .
- The fuel filler door on your vehicle does
not lock when you lock the vehicle from
the inside .

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
cooling of interna l eng ine components, all in
te rnal combust io n engines consume a certa in
amount of oil. Oil consumpt ion va rie s from
engine to engine and may change sign ifi can tly
ove r th e life of the engine. Typically, engines
wi th a spec ified break -in pe riod (see
¢ page 196) consume more oil during the
break-in pe riod than they cons ume after oi l
consumption has stabilized.
U nder normal cond itions, the rate o f oi l con
s u mption depen ds on the q ual ity and viscos ity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac
tors are the amount of oil dilut ion from water
condensa tion or fuel residue a nd the oxida
tion level of the oil. As any engine is subject to
wea r as m ileage builds up, the oil consump
t ion may incre ase over time until replacement
of wo rn components may be come necessary.
With a ll these va riab les coming into p lay, no
standard rate of oil consumpt io n can be es
tabl is h ed or spec ified. There is no alte rn ative
to regul ar and frequent che cking of the o il lev
el , see
Note.
If the yellow engine o il leve l warning sy mbo l
