vehicle, particularly the engine, and main­
taining its value. Even if the mileage driven
is low, the maximum period of one year
from one service to the next must not be ex­
ceeded.
@ Tips
The informat ion in the Service Rem inder re­

disconnected.
On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ift in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system .
The warning/indicator light illuminates when the
ignition is switched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates that the MIL is working properly .
If the light does not go out after the engine is
started, or illuminates while you are driving, a malfunction may exist in the engine system.
If
the light illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained high speeds and/or rapid accelera­
tions) and have the condition corrected. Contact
your authorized Audi dealer.
If the light illuminates, the electronic speed lim­iter may also be malfunctioning. For more infor­
mation
¢ page 29, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate ¢
page 200.

On-Board Diagnostics
Fig. 17 Loca tion of Data Link Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code. In case of a malfunction, the com­
ponent will be identified and the fault stored as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel f iller cap is prop­
erly closed
¢ page 200.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (gener ic scan tool for OBD).
In order to connect the special d iagnost ic equip­
ment, push the p lug into the Data L ink Connector
(DLC). The DLC is located to the right of the hood
release
¢ fig. 17.
Your authorized Audi dealer or qualified work­
shop can interpret the code and perform the nec­
essary repair.
.&, WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a co lli­
sion!

Fuel and Refueling
Fuel and Refueling
Fuel
Fuel supply
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 ins ide 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 minimum octane rat­
ing of 87 AKl/91 RON . However, using 87 AKI/91
RON octane fuel w ill slightly reduce engine per­
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 gaso line may not be available.
For more information on refueling your vehicle,
see
c::> page 200.
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
he lp prevent poss ible engine damage and a loss
of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
i n gs that can usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
- Regular Grade: 87 -90 AKI
198
Explanation of the abbreviations:
AKI= Anti Knock Index= (R+M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON = M otor Octane Number.
CJ) Note
- Do not use any fue l with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage will occur.
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions.
Blended gasoline
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixt ure 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-knoc k index must be 87 AK I or higher.
- Blend must not contain more than 15% etha-
nol.
- Vehicles with flexib le fue l eng ine: blend must
not contain more than 85% 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
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-ove r, we suggest that you .,.

Fuel and Refueling
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up ca used by the type
of gasoline you use.
Although gasoline grades d iffer from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on v ital 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
fue ls, built-up carbon depos its can rob your en­
g ine of peak performance.
CD 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 yo ur fuel tank.
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel f iller flap .
If the power locking system should fail, you can
still open the flap manually -for detailed instruc­
tions see
c> page 202.
You can find the fuel tank capacity of your vehicle
in
c> page 256 .
The label on the inside of the fuel filler flap tells
you the correct fue l for your vehicle. For more in­
formation about fuel specifications, see
<=>page 198.
Your vehicle fuel tank has an on-board refuelling
vapor recovery system. This feature he lps to pre­
vent fuel vapors from escaping from the tank and
200
polluting the environment whi le you refuel your
vehicle. In order to fill the tank proper ly while
protecting the env ironment, please follow th is
refueling procedure carefully.
A WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
can isters and other containers used to trans­
port fue l can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a col lision.
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).
CD Note
Never drive your vehicle until the fuel tank is
complete ly empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter the exhaust system and damage the catalytic
converte r.

pletely.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe b urns.
-
- Fuel is highly flammable and can cause se­
vere burns and other injur ies .
- Failure to shut the engine off wh ile refuel ­
ing and/or to insert the pump nozz le fully
into the fuel filler neck could ca use fue l to
spray out of filler neck or to ove rflow. Fuel
spray and overflowing fue l can cause a fire.
- Never use a cellular telephone wh ile refuel­
ing. The electromagnetic radiation can
cause spa rks that can ignite f uel vapors and
cause a fire.
- Never get back into your vehicle while refu­
eling. If in except ional circumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch meta l to discha rge static ele ctric­
ity befo re touching the filler noz zle ag ain.
Fuel and R efueling
Stat ic elect ricity can cause sparks that can
ignite fue l vapors released during refueling.
- Never smo ke or have an open flame any ­
where in or near your vehicle when ref ueling
or filling a portable fuel container .
- For your safety, we strongly recommend
that you do not trave l with a po rtable fuel
container in your veh icle. The container, fu ll
or empty may leak and co uld cause a fire,
especially in a crash.
- If, under except ional circumstances, you
m ust transport a portable fuel container,
p lease observe the following:
- Never fill a portab le fue l conta iner while it
is anywhere in or on the vehicle (for exam­
ple, in the l uggage compa rtment, o r on
the trunk). Static electricity can build up
while filling and can ignite fuel vapors caus ing a f ire .
-Always place a portab le fue l conta iner on
the ground before fi lling .
-A lways keep the f iller nozzle comp lete ly
inside the portable container before and
during f il li ng.
- If filling a portable conta iner made of
metal, the filler nozz le must always be in
contact with the container . This will he lp
prevent stat ic elec trici ty from discharging
and ca use a fire.
- Never spill fue l inside the vehicle o r lug­
gage compartment. F uel vapors a re highly
flammable.
- Always observe loca l and state/prov incial
laws rega rding the use, storage a nd trans­
po rtation of fuel contai ners.
- Make ce rtain the f uel con tainer mee ts i n­
dust ry standards (A NSI/ AS TM F852 -86).
(D Note
If any fuel has sp illed onto the car, it should
be removed immed iately to p revent damage
to the pa int.
@) For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first time,

Fuel and Refueling
the tank is full . Do not try to add more fuel
because fuel may spill out. In addition, the
expansion space in the fuel tank will be filled -
causing the fuel to overflow when it becomes
warm and pollute the environment.
(D Tips
- Running your engine while refuelling may
cause vapors to escape or even cause fuel to
sp ill out of the tank. This would then shut
off the fuel nozzle before the tank is full.
- Do not refuel your vehicle with the ignition
turned on. The fuel gauge may otherwise
not indicate the correct fuel level after refu­
elling .
- The fuel filler flap of your vehicle is not
l ocked when you lock the veh icle from the
inside .
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the
power locking system should fail.
