have approximately 1.9 gallons (7 litres) of
fuel left in the tank.
Time to refuel!
The total tank capacity of your vehicle is listed in
9 page 239.
(D Note
Never run the tank completely dry! An ir­
regu lar supply of fue l can cause eng ine
misfiring and fuel could enter into the ex­
haust system. The catalyt ic converter
co uld then overheat and be damaged.
Speedometer with odometer
The speedometer shows you the vehicle
speed, and the odometer shows you how
many miles (kilometers) you have driven.

matically lowering or raising the convertib le
top is not met and the switch to actuate the convertible top is pressed.
- The light i lluminates when the convertib le
top is opened or closed
incompletely.
nl /J Electronic stabilization program
(ESP)
If the G1 i ndicator lamp blinks while dr iv ing,
the ESP or ASR (Ant i-S lip Regulation) is active­
l y regulating.
If the G1 indicator lamp illuminates, the sys ­
tem has sw itched the ESP off. In this case, you
can switch the ignition off and then on to
switch the ESP on again. The system is func­
tioning completely whe n the indicator lamp
switches off .
I f the

was switched off with the
[ru bu tton.
ESP/ ABS fault! See owner's manual
If the G1 indicator lamp and the ll] ABS indi­
cator lamp illuminate and the dr iver message
appears, the ABS or e lectronic differential lock
is malfunctioning. This also interrupts the
E SP . The brakes st ill function with the ir nor­
mal power, but ABS is not active.
Drive to your authorized Aud i dea ler immedi­
ately to have the malfunction corrected .

of the On-Board Diagnostic (OBD II) system .
The symbol
rfl lights up when the ignition is
turned o n and will turn off after the engine
has started and ha s settled at constant idle
speed. This ind icates that the MIL is working
p roperly.
The warning light illuminates when there is a
malfunction in the engine e lectronic system. Contact
your authorized Audi dea ler and have
the malfunction corrected .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate

On-Board Diagnostic
system (OBD)
On-Board Diagnostics
Fig. 25 Locat ion of Data Link Connecto r (DLC)
On-Board Diagnostics monitors the compo­
nents of you r emission control system. Each
monitored compo nen t in your eng ine system
has been assigned a code . In case of a ma l­
function, the component will be identified
and the fau lt stored as a code in the control
module memory.
The MIL light may a lso illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem .
If the light illuminates after a refuelling,
stop the vehicle and make sure the fuel filler
cap is properly closed ¢
page 176.
In o rder to make an accurate diagnosis, the
stored data can only be displayed using spe­
cia l diagnostic equipment (generic scan tool
for OBD).
I n o rder to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (DLC). The DLC is located to the
right of the hood release¢
fig. 25.
Your authorized Audi dea ler or a qualified
service station can interpret the code and per­
form the necessary repair .
Malfunction Indicator lamp (MIL)
The Malfunction Indicator Lamp (MIL) &'I in
the instrument cluster¢
page 13, fig. 6 is
part of the On-Board Diagnostic COBO II) sys­
tem .
The warning/indicator light illuminates when
the ignit io n is switched on and goes out after
the e ngine starts and the idle has stabilized.
Th is indicates that the MIL is working prope r­
ly.
If th e light d oes not go out after the engine
is started, or illum inates wh ile you are dr iv­
ing, a malfunc tion may exist in the engine sys­
tem.
If the light illum inates, the catalytic con­
verte r could be damaged .
Continue driving
with reduced p ower (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact you r authorized Audi dea le r.
If the light illum inates, the electronic speed
limi ter may also be malfunct ioning . For more
i nformation ¢
page 28, Electronic speed
limiter.
An improperly clo sed fu el filler cap ma y also
cau se the MIL light to illuminate
¢ page 176.
Electronic speed limiter
Your vehicle may be factory eq uipped w ith
tires that are rated for a maximum speed of 130 mph (210 km/h) . This is less than the
maximum speed of your vehicle. To reduce the
risk of sudden tire fai lure and loss of control if
the vehicle is operated at excessive speeds,
your vehicle a lso has an electronic speed limit­
er . The electronic speed limiter prevents your
vehicle from going faster than the tire speed
rating. Fo r more information

-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time .
(D 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 fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its 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 l ems 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
Fuel supply and filling your fuel tank 175
fuel systems clean, they are not equally effec ­
tive .
A udi 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, built-up carbon deposits can rob yo ur
engine of peak performance.
Q) Note
Damage or malfunction due to poor fue l
quality is not covered by the Aud i 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 fille r flap.
If the unlocking system should fail, you can
still open the flap manually -for detailed in ­
structions see ¢
page 177.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢ page 239.
The label on the inside of the fuel fi ller flap
tells you the correct fue l for your vehicle. For
more information about fuel specifications,
see ¢
page 174.
Your vehicle fue l tank has an on -board refue l­
li ng 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 fo llow this refueling procedure careful­
ly.
_&. WARNING
Under normal operating conditions, never
carry additional fue l conta iners in yo ur car.
Gas canisters and other containers used to
transport f uel can be dangero us. Such con­
tainers, 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 al­
ways observe local and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 - 86).
(D Note
Never drive your vehicle until the fuel tank
is completely dry. The irregular supply of
fuel can cause misfiring. Gasoline could
enter into the exhaust system and damage
the catalytic converter.
Refuelling
Fig. 132 Driver's door: Un locking fuel filler flap
Fig. 133 Fuel cap hooked on the opened fue l filler flap
When adding fue l, the ignition and any ce llu­
lar phones in the vehicle must be switched
off .
Taking the fuel cap off
• To open the fuel filler flap, pull the button
9fig. 132.
• Unscrew fuel filler cap counter-clockwise
and hang it on the fuel filter flap¢
fig. 133 .
Refuelling procedure
• Insert the fuel nozzle from the gasoline
pump into the fuel filler neck as far as it will
go.
• Select a medium refuelling rate so that the
nozzle switches off automatically when the
tank is full.
Putting the fuel cap back on
• After filling your tank, twist the fuel filter
cap clockwise until you hear a definite click.
• Close the fuel filler flap.
To avoid fuel spilling or evaporating from the
fuel tank always close fuel filler cap properly and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp¢
page 28
to come on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fue l is highly flammable and can cause
severe burns and other injuries.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filter neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can
cause a fire.
- Never use a cellular telephone while re­
fueling. The electromagnetic radiation
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle while re­
fueling.
If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling .
- Never smoke or have an open flame any­
where in or near your vehicle when refu­
eling or filling a portable fuel container.

-For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle (for example, in the luggage compart­
ment, or on the trunk) . Static electrici­
ty can build up while filling and can ig­
nite fuel vapors causing a fire.
- Always place a portable fuel container
on the ground before filling .
-Always keep the filler nozzle complete­
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozzle must always be
in contact with the container. This will
help prevent static electricity from dis­
charging and cause a fire.
- Never spill fuel inside the vehicle or
luggage compartment. Fuel vapors are
highly flammable.
- Always observe local and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F852-86).
(D Note
If any fuel has spilled onto the car, it
should be removed immediately to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correctly operated nozzle switches off automatically for the first
time, 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
Fuel supply and filling your fuel tank 177
overflow when it becomes warm and pol­
lute the environment.
a) Tips
- Running your engine while refuelling
may cause vapors to escape or even 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 igni­
tion switched on. The fuel gauge may
otherwise not indicate the correct fuel
level after refuelling.
Unlocking the fuel filler flap
by hand
You can open the fuel filler flap by hand if the
power locking system should fail .
Fig. 134 Lu ggage compartment: Cover in the right ­
side interior trim
If the power locking system should fail, you
can still open the flap manually:
.. Open the rear lid.
.. Open the round cover in the right-side interi­
or trim .
.. Remove the red plastic knob from its retain­
er.
.. Pull the plastic cord in the direction of the
arrow to unlock the fuel filler flap
~fig. 134 .

-Apply the parking brake.
- Move selector lever to "P" (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wa it until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
-If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever to "P" (Park).
Checking and filling 179
-Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts . Tie back hair before
starting, and wear no clothing that will
hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards
