210 Checking and Filling
Checking and Filling
Gasoline
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 of91 AKI (95
RON) . For more information on TOP TIER De ­
tergent Gasol ine, please go to the official
website (www .toptiergas.com).
The recommended gasoline octane rating for
your engine can also be found on a label locat­
ed on the ins ide 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 engine 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 available.
For more information on refueling your vehi­
cle, see
~ page 212.
Octane rating
Octane rating ind icates 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
r atings that can usually be found on the filler
pump : - Premium Grade: 91
-96 AKI
- Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI= Anti Knock Index= (R+M)/2 = (RON
+MON)/2
RON= Research Octane Number
MON = Motor Octane Number .
@ Note
-Do not use any fuel w ith octane ratings
lower than 87 AKI or 91 RON otherwise
expensive engine damage w ill occur.
- Do
not use leaded gasoline. The use of
leaded gasoline will 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
following criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti-knock index must be 87 AK I 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 contain more than 15%
ethanol.
Blend of gasoline and MTBE
-Anti-knoc k index must be 87 AK I or higher.
- Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline

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 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
M
N fuel systems clean, they are not equally effec-o
iii 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.
Diesel fuel
App lies to vehicles : wit h diese l eng ine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2 . The ULSD No. 2 meets the ASTM D975.
Diesel fuel with concentrations of biodiesel
higher than 5
% such as B11, B2O or B1OO are
strictly prohibited.
Service station fuel pumps are labeled with
the correct fuel information for easy recogni­
tion by the user.
If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav­
eling to other countries.
ULSD No. 2 can become thicker in very cold
temperatures, and this can impair the en­
gine's starting and running. Depending on the
season, gas stations provide ULSD No . 2 that
flows better in cold temperatures so that you
can continue operating your vehicle as usual.
(D Note
- Your vehicle's diesel engine was de­
signed solely for use with ULSD No. 2.
Therefore, never use gasoline, heating
oil, other fuels or flow improvers. These
contain substances that will severely
damage the fuel system and the engine.
Such damage will not be covered by your
New Vehicle Limited Warranty.

212 Checking and Fill in g
- If you put any amount of incorrect fue l in
the fue l tank, do not start the engine un­
der any circumstances. Immediately con­
tact the nearest authorized Audi dealer
or authorized Audi Service Facility for as­
sistance. These fuels contain substances
that can severely damage the fuel sys­
tem and the engine if the engine is start­
ed.
- If the diesel fuel quality is poor, it may
be necessary to have the water drained
from the water sepa rator in the
f ue l fi l­
te r
more often than specified in the
maintenance schedu le . This can help re­
duce engine ma lfunctions

The fuel filler neck is located on the right rear
side panel behind the fuel fi ller flap.
If the power locking system should fail, you
can st ill open the flap manually- for detailed
instructions
seer:::.> page 214.
You can find the fuel tank capacity of your ve­
hicle in
Qpage 288.
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
c;,page 210.
Your veh icle fuel tank has an onboard refue l­
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 protect ing the env ironment,
p lease follow t his refueling procedure careful­
ly.
.&_ WARNING
Under norma l operating conditions, neve r
carry additiona l fuel containers in your car .
Gas can isters and other containers used to
transport fue l can be dangerous. Such con­
tainers, full or empty, may leak and cou ld
cause a f ire in a collision. If you must transpo
rt fuel to use for your lawn mower,
snow b lower, etc., be very careful and al­
ways observe local and state laws regard­ ing the use, transportation and storage of
such fuel containers. Make certa in the con­
tainer meets industry standa rds (ANSI/
ASTM F8S2 -86).
(D Note
Neve r drive your veh icle until the fue l tank
i s completely empty. The irregular supply
of fue l can cause misfir ing. Gasoline cou ld
enter the exhaust system and damage the
catalytic converter.

A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, ex­
plosions or serious injuries.
- Fuel ignites easily and can cause serious
burns and other injuries.
- If you do not switch the engine off when
fueling 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, which 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 vehicle again while fueling, close
the door and touch metal to discharge
static electricity before touching the fuel
nozzle. Static electricity can create
sparks, which can ignite vapors when fu­
eling.
Checking and Filling 213
- Do not smoke or have an open flame in
the area when fueling your vehicle or fill­
ing a fuel container because this increas­
es 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 fill 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
sion.
- 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 discharging.
- Never spill fuel in the vehicle or the
luggage compartment. Evaporated fuel
is explosive 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 industry standards (ANSI/ASTM
F8S2-86).
@ 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

the risk of damage to the catalytic con ­
verter .
- If the fuel tank runs comp letely empty in
a vehicle with a
die sel en gine , the igni­
tion must remain switched on for at l east 30 seconds after refueling before
starting the engine.
It may take longer
than usual for the engine to start, even up to a minute . Th is is because the air
must fi rst b leed out of the fuel system
when starting the eng ine.
@) For the s ake 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 t ry to add more fuel, because it can
spill over. Also , the expansion space in
the tank will fill, which can resu lt in fuel
spilling out when it becomes warm and po lluting the environment .
@ Tips
-If the engine is runn ing whi le fueling, va­
pors can escape or the fuel can spi ll over.
Because of this , the fuel nozz le 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 af­
ter fueling the vehicle.
- Diesel vehicles are equipped with a diesel misfueling guard
ll. It allows the vehicle
to be fueled only with a diese l fuel pump
nozzle.
- A worn or damaged nozzle or a nozz le
that is too small may not be able to open
the d iesel m isfueling protector . If this is
the case, try t urni ng the nozzle before
i nserting it in the f uel filler neck, use a
different fuel p ump or see you r a uthor­
i zed Audi dealer or author ized repair fa­
cility for assistance .
- The m isf ueli ng guard does not open
when adding fuel from a fuel container .
ll Market-sp ec ifi c
You can bypass it by adding the diesel
fuel s lowly.
- The fuel fi ller door on your vehicle does
not lock when you lock the vehicle from
the inside.
