Electronic power control
,._
This warning/indicator light monitors the electr onic
power control.
The warning/indicator light (Electronic Power Control) i llumi -
nates when you turn on the ignition as a function check.
[ i ] Tips
If this warning/indicator light illuminates whi le you are driving, then
there is a malfunction in the engine electronics . Have the malfunc­
tion corrected as soon as possible by your authorized Audi dea ler or
qualified repair facility .•
Generator D
This warning/indicator light detects a malfunction in the
generator or in the vehicle's electrical system.
The O warning/indicator light i lluminates when you switch on the
ignition and must go out after the engine has started.
If the O warning/indicator light illuminates while you are driving,
you should contact your authorized Audi dealer . Since the vehic le battery is discharging, you should switch off any unnecessary elec
­
t rical consumers (for example, the air conditioner) .
0 Note
If the _f_ warning/indicator light (malfunction in the engine coo ling
system) in the instrument cluster should illuminate=>
page 31, stop
the vehicle and turn off the engine . The water pump is not working
- this can cause engine damage. •
Electronic stabilization program (ESP) This warning/indicat or light monitors the electr onic stabi ­
lization program .
The warning/indicator light has the following functions:
• It blinks while you are driving when the ESP is working .
• It illuminates when you switch on the ignition for approximate ly
2 seconds as a function check .
• It illuminates when there is a malfunction in the ESP. The
message
E S P f ault ! Se e owner 's manual also appears in the instru ­
ment cluster display and a warning tone sounds .
• It illuminates continuously when the ESP is switched off .
• It illuminates if there is a malfunction in the ABS, since the ESP
is part of the ABS system.
If the battery terminals were disconnected and re-connected , the
vehic le was jump started or the batte ry is very weak, the ESP sensor
system goes through a learning process for the first few yards. The
warning/indicator light illuminates . The warning/indicator light
goes out as soon as the learning process is complete.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine, this may mean that the control system has
temporarily switched off the ESP . If this is case, you can reactivate
the ESP by turning the ignition off and then on again . The .,_

Fuel supply and filling your fuel tank 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
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
filler cap may also cause the MIL lamp=>
page 27to come on.
& 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 refueling and/or to insert
the pump nozzle fully into the fuel filler neck could cause fuel to spray out of filler neck or to overflow. Fuel spray and overflowing
fuel can cause a fire.
• Never use a cellular telephone while refueling . The electromag­
netic radiation can cause sparks that can ignite fuel vapors and
cause a fire.
• Never get back into your vehicle while refueling. If in excep­
tional circumstances you must get back in your vehicle while refu­
eling, make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again.
Static electricity can cause sparks that can ignite fuel vapors
released during refueling .
& WARNING (continued)
• Never smoke or have an open flame anywhere in or near your
vehicle when refueling 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 container, 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 compartment, or on
the trunk). Static electricity can build up while filling and can
ignite fuel vapors causing a fire.
- Always place a portable fuel container on the ground before
filling.
- Always keep the filler nozzle completely 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 discharging and cause a fire.
- Never spill fuel inside the vehicle or luggage compartment. Fuel vapors are highly flammable .
- Always observe local and state/provincial laws regarding the
use, storage and transportation of fuel containers.
- Make certain the fuel container meets industry standards
(ANSI / ASTM F852-86l.
0 Note
If any fuel has spilled onto the car, it should be removed immedi -
ately to prevent damage to the paint. _.,

& WARNING (continued)
• When disconnecting the battery, first disconnect the negative
cable and then the positive cable.
• Before reconnecting the battery, make sure all electrical
consumers are switched off. Reconnect the positive cable first and
then the negative cable. Never interchange the cables -this could
start a fire!
• Never charge a frozen or a thawed-out battery. It could
explode! If a battery has frozen, then it must be replaced. A
discharged battery can freeze over at 32 °F (0 °CI.
• Make sure the vent hose is always attached to the opening on
the side of the battery.
• Never use batteries which are damaged. There is the danger of
an explosion! Always replace a damaged battery.
& WARNING
California Proposition 65 Warning:
• Battery posts, terminals and related accessories contain lead
and lead compounds, chemicals known to the State of California
to cause cancer and reproductive problems. Wash hands after
handling.
0 Note
• Do not disconnect the vehicle battery when the ignition is
switched on or when the engine is running, otherwise, you will
damage electronic components in the electrical system.
• If your vehicle is going to stand for a long period of time without
being driven, protect the battery from "freezing", otherwise it will
be damaged and will then have to be replaced .•
Battery charging
Starting the engine requires a well charged battery.
Always read and heed all WARNINGS below=> & and => &
in "Working on the battery" on
page 321.
-Turn off the ignition and all electrical consumers.
- Make sure the area is well ventilated when you charge
the battery.
- Attach the red (positive
8) clamp of the charging equip­
ment to the positive terminal of the battery and the black
(negative(:)) clamp to the jumper terminal.
- Only now plug the mains lead for the charging equip­
ment into the wall outlet and turn it on=> &.
-Make sure the charging rate is not over 30 amps/14.8
Volt.
-When the battery is fully charged: Turn the charging
equipment off and remove the mains lead from the wall
outlet.
- Now remove the clamps for the charging equipment .
A discharged battery can freeze at temperatures of only O °C . Allow
a frozen battery to thaw completely before attempting to charge it
=> &. However, we recommend not using a thawed battery again
because the battery casing can be cracked due to ice formation and
can leak battery acid.
Battery charging (Maximum charging rate of 30
amps/14.8 Volt)
When charging at /ow voltages (e.g. with a trickle charger), the
battery cables do not have to be disconnected first. The battery caps
should
