system and operate telephone functions through
your MMI. You can make calls using the antenna
on your cell phone.
A WARNING
- Medical experts warn that cell phones can
interfere w ith the function of pacemakers.
Always ma inta in a m inimum distance of 20
centimeters between the cell phone anten­
na and the pacemaker.
- Do not carry the cell phone in a pocket di­
rectly over the pacemaker when the phone
is switched on.
- Sw itch the cell phone off immediately if
you suspect it may be interfering with the pacemaker.
- Do not use the voice recognition system*
c::> page 168 in emergencies because your
voice may change in stressful situations. It may take longer to dial the number or the
system may not be able to dia l it at all. Dial
the emergency n umber manua lly.
- Switch your cell phone off in areas where
there is a risk of an exp losion. These loca­
tions are not always clea rly marked. This
may include gas stations, fuel and chemical
storage facilities or transport vehicles, or lo ­
cations where fuel vapors (such as propane
or gasoline vapor in vehicles or bu ildings),
chem icals or large quantities of dust parti­
cles (such as flour, sawdust or metal) may
be present in the air. Th is also applies to all
other locations where you would normally
tu rn your vehicle engine off.

Checking and Filling
Gasoline
Fuel supply
Applies to: veh icles with gaso line engine
Using the right fuel helps keep the environment
clean and prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
grade gasoline. Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
p lease go to the official website
(www.toptiergas .com) .
The recommended gasoline octane rating for
your engine can also be found on a label located
on the inside of the fuel filler flap . This rating
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a min imum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKl/91
RON octane fuel will slightly reduce engine pe r­
formance.
Use unleaded gasoline only. Unleaded gasoline
is available throughout the USA , Canada, and in
most European countries . We recommend that
you do not take your vehicle to areas or countries
where un leaded gasol ine may not be available.
For more information on refueling your vehicle,
see
c::> page 317 .
Octane rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore , buy ing
the correct grade of gasoline is very important to
h e lp prevent possible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
ings that can usually be found on the filler pump:
- Premium Grade: 91
-96 AKI
Checking and Filling
-Regu lar Grade: 87 -90 AKI
E xplanation of the abb reviations:
AKI =
Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = R esearch Octane Number
MON = Motor Octane Number.
(D Note
- Do not use any fuel w ith octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage w ill occur .
- Do
not us e leaded gasoline. The use of lead­
ed gasoline will severe ly damage your vehi­
cle'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 al­
cohol or MTB E (commonly referred to as oxygen ­
ates) if the blended mixture meets the following
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% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- Anti-knock index must be 87 AKI or higher.
- Blend must not conta in more than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti-knock 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 es­
pecially well for winter or summer dr iving . Dur-
ing seasonal change-over, we suggest that you
..,.
315

Checking and Filling
fill up at busy gas stations where the seasonal
adjustm ent is more likely to be mad e in time.
0 Note
- Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the speci­
fied criteria in this chapter .
- If you are 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
Applies to: vehicles with gasoline engine
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) .
316
After an extended period of using inadequate
fuels, built-up carbon deposits can rob your
en­
gine of peak performance.
([) Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New Vehi­
cle Limited Warranty.
- Do not add aftermarket fuel additive prod­
ucts to your fuel tank.
Diesel fuel
Applies to: vehicles with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) No. 2.
The ULSD No. 2 meets the ASTM 0975.
Diesel fuel with concentrations of biodiesel high­
er than 5
% such as 811,820 or 8100 are strictly
prohibited.
Service station fuel pumps are labeled with the
correct fuel information for easy recognition by
the user. If the diesel fuel pump is not labeled
ask the station operator what fuel is being dis­
pensed before filling up your vehicle.
ULSD No. 2 may not be available outside the USA
and Canada. Be sure to check before traveling to
other countries.
ULSD No. 2 can become thicker in very cold tem­
peratures, and this can impair the engine's start­
ing and running . Depending on the season , gas
stations provide ULSD No. 2 that flows better in
cold temperatures so that you can continue oper­
ating your vehicle as usual.
(D Note
- Your vehicle's diesel engine was designed
soley 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 War­
ranty.
- If you put any amount of incorrect fuel in
the fuel tank, do not start the engine under
.,..

any circumstances. Immediately contact the
nearest authorized Audi dealer or author­
ized Audi Service Facility for assistance.
These fuels contain substances that can se­
verely damage the fuel system and the en­
gine if the engine is started.
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 319.
You can find the fuel tank capacity of your vehicle
in
¢page 381.
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 315.
Your veh icle fuel tank has an onboard refuelling
vapor recovery system. This feature he lps to pre­
vent fuel vapors from escap ing 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.
A 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).
(D Note
Never dr ive your vehicle until the fuel tank is
completely empty. The irregu lar supply of
Checking and Filling
fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

Checking and Filling
filler door. For additional information on fuel,
see
<=> page 315.
The fuel tank capacity of your vehicle is listed in
the
Technical Data section <=> page 381.
To avoid fuel spilling or evaporating from the fuel
tank always close fuel cap properly and com­
pletely . An improperly closed fuel filler cap may
also cause the MIL lamp
<=>page 24 to come on.
A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, explo­
sions or serious injuries.
- Fuel ignites easily and can cause serious
burns and other injuries .
- If you do not switch the engine off when fu­
eling and/or do not insert the fuel nozzle
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 electric­
ity before touching the fuel nozzle . Static
electricity can create sparks, which can ig­
nite vapors when fueling.
- Do not smoke or have an open flame in the
area when fueling your vehicle or filling a
fuel container because this increases the
risk of an explosion .
-For your safety , carrying fuel containers in
your vehicle is not recommended. Whether
full or empty, the container can leak and
cause a fire in the event of an accident.
-If you must make an exception and trans­
port a fuel container, note the following:
- Never fill the fuel container with fuel
while it is in or on the vehicle . Stat ic elec ­
tricity is discharged when filling which can
cause the fuel vapors to ignite and in­
creases the risk of an explosion.
- Always place a fuel container on the
ground before filling.
318
-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 contact with
the container when filling it with fuel. This
prevents static electricity from discharg­
ing .
-Never spill fuel in the vehicle or the lug­
gage compartment . Evaporated fuel is ex­
plosive and increases the risk of serious in­
jury or death .
- Follow legal requirements when using, storing and transporting fuel containers .
-Make sure the fuel container conforms to
industry standards (ANSI/ASTM F8S2 -86).
{(D Note
- Remove spilled fuel from vehicle paint im­
mediately, because it can damage paint.
- 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 exhaust
system and increase the risk of damage to
the catalytic converter.
- If the fuel tank runs completely empty in a
vehicle with a
diesel engine, the ignition
must remain switched on for at least 30
seconds after refueling before starting the
engine.
It may take longer than usual for
the engine to start, even up to a minute.
This is because the air must first bleed out
of the fuel system when starting the engine.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming up.
@ Tips
Diesel vehicles are equipped with a diesel mis­
fueling guard.
It allows the vehicle to be fu­
eled only with a diesel fuel pump nozzle. A
worn or damaged nozzle or a nozzle that is
too small may not be able to open the diesel
misfueling guard. If this is the case, try turn­
ing the nozzle before inserting it in the fuel
filler neck, use a different fuel pump, or see
