This indicates that the MIL is working proper­
ly.
If the light does not go out after the engine
i s started, or illuminates whi le you are driv­
ing, a ma lfunction may exist in the engine sys­
tem .
If the light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing susta ined high speeds and/or rapid accel­
erat ions) and have the condition corrected.
Contact your authori zed Audi dealer .
If the light illuminates, the electronic speed
limiter may also be ma lfunctioning. For more

On-Board Diagnostics
Fig . 16 Locat io n of Data Link Co nnector (D LC)
On-Board Diagnostics monitors the compo­
nents o f your emission control system. Each
monitored component in your engine system
has been assigned a code. In case of a mal­
function, the component will be identified
and the fault 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 veh icle and make sure the fuel filler
cap is properly closed
Q page 22 7. In order to make an accurate diagnosis, the
stored data can on
ly be displayed using spe­
c ial diagnostic equipment (generic scan tool
for OBD).
In order to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (D LC). The DLC is located to the
right of the hood release~
fig. 16.
Your authorized Audi dea ler or a qualified
service station can interpret the code and per­
form the necessary repair.
A WARNING
-Do not use the diagnostic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a collision!
Electronic speed limiter
-
Your vehicle may be factory equipped w ith
t ir es 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 also has an e lectronic speed limit­
er . The electronic speed limiter prevents your
vehicle from going faster than the tire speed
rating . For more information
Q page 257.
If the engine control unit receives faulty vehi­
cle road speed signals, the Malfunction Indi­
cator Lamp (MIL)
¢fj will illuminate . If this
occurs, contact the nearest authorized Audi
dealer for assistance.
S models
Your vehicle's top speed is electronica lly limit­
ed to 155 mph (250 km/h).
If the engine control unit receives faulty vehi­
cle roadspeed signals, the Malfunction Indica­
tor Lamp (MIU¢.§ will illuminate . If this oc­
curs, contact the nearest authorized Audi
dealer for assistance.

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 F8S2 -86) .
@ Note
Never drive your vehicle until the fuel tank
is completely empty. The irregular supply
of fuel can cause misfiring. Gasoline could
enter the exhaust system and damage the
catalyt ic converter.
Refuelling

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 filler
cap clockwise as far as it will go.
• Close the fuel filler flap.
To avoid fuel spill ing or evaporating from the
fuel tank always close fuel filler cap proper ly
and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp ¢

to come on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel 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 filler neck could cause
fue l 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
fue ling. The electromagnet ic rad iation
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 fue l container.
- For your safety, we strongly recommend
that you do not travel with a portable

228 Fuel supply and filling your fuel tank
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 bui ld 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 nozz le 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 conta iners .
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F8S2 -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 noz zle
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
overflow when it becomes warm and pol­
lute the environment.
(D Tips
-Running your engine whi le refue lling
may cause vapors to escape or even
cause fuel to spi ll out of the tank. This
would then shut off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may otherwise not ind icate the correct fuel
level after refuelling .
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from
the ins ide .
Fuel filler flap emergency release
You can open the fuel filler flap by hand if the
power locking system should fail.

or coolant escaping from the engine compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood .
'Working in the engine compartment
Be especially careful whenever you work in
the engine compartment.
Whenever you must perform any work in the
engine compartment, for example checking
and filling different fluids, there is a risk of injury, burns and accidents. To prevent per­
sonal injury always observe the following
WARNINGS. The engine compartment of any
vehicle is a hazardous area
~ ,&. .
A WARNING
To help avoid injury, before you check any­
thing under the hood:
- Turn off the engine.
- Switch off the ignition .
- 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. Wait 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.
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
