page 28 . Malfunctions or faults wil l be identified either with a red
symbol (pr iority 1 -Danger!) or with a yel low symbol (priority 2 -
Warning). •
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) .

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

• 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

Service interval display
The service interval display reminds you when your next
service is due.
Fig. 14 Display:
Service interval display
The date for service is calculated automatically. Based on the
average distance driven in previous months, a monthly driv ing
distance is calculated . As soon as the distance remaining to the next
service drops below the distance driven monthly, the service
reminder is initiated. The maximum period from one service to the
next is one year.
Service reminder
30 days b efore the next service is due, a service reminder appears
in the display when you turn on the ignition => fig. 14.
Contro ls and eq uip­
ment
Driver information display
After about 5 seconds the display switches back to normal. The
distance and time remaining are updated each time the ignition is
turned on until the date due for service is reached .
Service
When the due date for service is reached, the message Service due
! appears in the display immediately after you turn on the ignition.
Additionally, a warning tone sounds . After about 5 seconds the
display switches back to normal.
0 Note
If you disconnect the battery terminals, no calculations can be
made for the service interval display during this time and no service
reminder will appear . Remember that observing the proper service
intervals is vitally important to extending the life of your vehicle,
particularly the engine, and maintaining its value . Even if the
mileage driven is low, the maximum period of one year from one
service to the next must not be exceeded. •
On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (Mill in the instrument cluster
=>
page 16, fig. 7 is part of the On -Board Diagnostic (OBD II) system.
The warning/indicator light illuminates when the ignition is switched on and goes out after the engine starts and the idle has
stabilized. This indicates 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 starts flashing , the catalytic converter could be damaged .
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition
corrected. Contact your author ized Audi dealer .

Memori es
The trip computer is equipped with two fully automatic
memones.
Fig . 22 Trip computer
display: memory level 1
You can switch between the trip computer 1 and 2 by pressing the
Reset button
@ ~ page 40, fig. 23.
You can tell which memory level is currently active by the number in
the display ~ fig . 22. The data from the single -trip memory
(memory level 1) is being displayed if a
1 appears . If a 2 is shown ,
then the data from the total -trip memory is being disp layed
(memory level 2).
Single-trip memory (Trip computer 1 )
The single-trip memory stores the trip information from the time the
ignition is turned on until it is turned off. If the trip is continued
within 2 hours from the time the ignition was turned off, the new
data will be included in the calculation of the current trip informa­
tion. If the trip is interrupted for
more than 2 hours the memory is
reset automatically.
Total-trip memory (Trip computer 2)
Unlike the single -trip memory, the total -trip memory is not reset
automatically . This permits you to evaluate your driving data for the
entire period between manual resets .•
