Driver information system
On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢• in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system.
The warning/indicator light i lluminates 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 acce lerations)
and have the condition corrected. Contact your
authorized Audi dealer.
I f the light illuminates, the electronic speed lim­
iter may also be malfunctioning. For more infor­
mation
c::> page 28, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c::> page 192.
On-Board Diagnostics
Fig. 16 Loca tion of Data Link Connec tor (DLC)
On-Board Diagnostics monito rs the components
of your emission control system. Each monitored
component in your engine system has been as­
signed 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 .
28
The MIL light may also illuminate if there is a
l eak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed
c::> page 192.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using spec ia l diag­
nostic equipment (generic scan tool for 080).
In order to connect the specia l diagnostic equip ­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the r ight of the hood
release
c::> fig. 16.
Your authorized Audi dealer or qualified work­
shop can interpret the code and perform the nec­
essary repair.
A WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!
Electronic speed limiter
Your vehicle may be factory equ ipped with tires
that are rated for a maximum speed of 130 mph
(210 km/h) . This is may be less than the maxi­
mum speed of your vehicle. To reduce the risk of
sudden tire failure and loss of control if the vehi ­
cle is operated at excessive speeds, your vehicle
has an e lectronic speed limiter. The electronic
speed limiter prevents your vehicle from going
faster than the tire speed rating. For more infor­
mation
c::> page 209.
-
If the engine contro l unit receives faulty vehicle
roadspeed signals, the Malfunction Indicator
Light (MIL)
II will illuminate. If this occurs, con­
tact the nearest author ized Audi dealer for assis­
tance.
A WARNING
Always observe the posted speed lim its and
adjust your speed to suit prevailing road, traf­
fic and weather conditions. Never drive your
vehicle faster than the maximum speed rating
of the tires installed.

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,
please go to the official website
(www.toptiergas.com).
The recommended gasoline octane rating for
your eng ine 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 AKl/91
RON octane fue l will s lightly reduce eng ine 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 unleaded gasoline may not be available.
For more informat ion on refueling your vehicle,
see
~page 192.
Octane rating
Octane rating ind icates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignition and detonation. Therefore, buying
the correct grade of gasoline is very important to
he lp prevent possible eng ine 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
190
Explanation of the abbreviations:
AKI= Anti Knock Index= (R+M)/2 = (RON+MON)/
2
RON = Re search Octane Number
MON= Motor Octane Number.
CJ) Note
- Do not use any fuel 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 a l­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixture mee ts the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knock index must be 87 AKI or h igher .
- 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 h igher.
- Blend must not contain more than 1S% etha-
nol.
- Veh icles with flex ible fuel engine: 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-over, we suggest that you ""

Fuel and R efue lin g
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 differ from one manu­
facturer to another, they have certa in things in
common. All gaso line grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l 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 T IER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the officia l website
(www.toptiergas.com).
After an extended period of using inadequate
fue ls, built-up carbon deposits can rob your en­
g ine of peak performance .
CD Note
-Damage or ma lf u nction due to poor fuel
quality is not covered by the Aud i New Vehi­
cle Limited Warranty .
- Do not add aftermarket f uel addit ive prod­
ucts to your fuel tank.
Refueling
Fuel filler neck
The fuel f iller neck is located on the r ight rear
side panel behind the fuel f iller flap .
If the power Locking system should fail, you can
still open the flap manually -for deta iled instruc­
tions seer:>
page 194.
You can find the fue l tank capacity of your vehicle
in r:>
page 246 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fue l specifications, see
c:> page 190 .
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
192
po lluting the environment while you refuel your
vehicle. In order to fi ll the tank properly while
protecting the environment, please follow this
refueling procedure carefu lly.
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 fuel can be dangerous. Such containers,
fu ll or empty, may leak and could ca use a fire
in a co llision.
If you must tra nsport f uel 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 fue l containers . Make cer­
tain the container meets industry standards (ANSI/ASTM F852 -86).
CD Note
Never drive your vehicle until the fue l tank is
complete ly empty. The irregular supply of
f u el can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

wise as far as it wi ll go.
.,. Close the fuel filler flap .
To avo id f uel spi lling or evaporating from the fue l
tank always close fuel cap properly and com ­
p letely.
A WARNING
Improper refueling or handling of fue l can
cause fire, exp losion and severe burns.
-
- Fuel is highly flammable and can cause se­
vere burns and other injuries.
- Failure to shut the engine off whi le refuel­
ing and/or to insert the pump nozzle fu lly
into the fuel filler neck could cause fue l to
spray out of f iller neck or to overflow. Fuel
spray and overflow ing fuel can cause a fire.
- Never use a cellular telephone wh ile refuel­
ing. The electromagnetic radiation can
cause sparks that can ignite fuel vapors and
cause a fire.
- Never get back into your vehicle while refu­
eling. If in exceptional c ircumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch meta l to discharge static e lectric­
ity before touching the filler nozzle again.
Fu el and R efu elin g
Static electricity can cause sparks that can
ignite fue l vapors released during refue ling.
- Never smoke or have an open f lame any­
where in or near your vehicle when refueling or filling a portable fuel conta iner .
- For your safety, we strongly recommend
that you do not travel with a portable f uel
container in your veh icle. The container, full
or empty may leak and cou ld cause a fire,
especially in a crash .
- If, under exceptional c ircumstances, you
must transport a portab le fuel container,
please observe the following:
- Never fill a portable fuel container while it
is anywhere in or on the vehicle (for exam­
ple, in the l uggage compartment, or on
the trunk). Static e lectric ity can build up
while filling and can ignite fuel vapors
caus ing a fire .
-Always place a portab le fue l conta iner on
the ground before fill ing .
- Always keep the filler nozzle completely
inside the portable container before and
during f il li ng.
- If filling a portab le container made of
metal, the f iller nozzle must always be in
contact with the container. This will help prevent static electricity from d ischarging
and cause a fi re.
- Never spill fuel inside the vehicle or lug­
gage compartment. Fuel vapors are highly
flammable.
- Always observe local and state/provincial
laws regarding the use, storage and trans­
po rtation of fue l conta iners.
- Make certain the fuel conta iner meets in­
dustry standards (ANSI/ AS TM F852 -86).
(D Note
If any fuel has sp illed onto the car, it should
be removed immediately to prevent damage
to the pa int.
@) For the sake of the environment
As soon as the correct ly operated nozzle
switches off automat ically for the first time,
193

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
spill 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
locked when you lock the vehicle 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.
