Malf unctions or faults will be identified either with a red symbol
(pr iority
1-Dange r!) or with a ye llow symbo l (prio rity 2 -Warn ing). •
Electronic power control C
This warning/indicator light monitors the electronic
power control.
The warn ing/indicator light (Electro nic Power Control) illumi-
nates when you turn on the ignition as a function check .
(I] Tips
If this warning/indicator light illuminates while you are driving, then
there is a malfunct io n in the engine electron ics . Have the ma lfunct io n
corrected as soon as possib le by your authori zed Audi dealer or qual­
ified repair fac ility. •
Generator 0
This warning/indicator light detects a malfunction in the
generator or in the vehicle's electrical system.
T he O warning/ind icator light illum inates when you sw itch on the
ignition and must go out after the engine has started .
If the O warning/indicator light illum ina tes while you are d riving,
you should contact your authorized Audi dea ler. Since the veh icle
bat tery is d ischarging, you shou ld switch off any unnecessary elec ­
trical consumers (for example, the air conditioner) .

Electronic stabilization program (ESP) ,
This warning/indicator light monitors the electronic
stabilization program .
The war ning/ indicator lig ht has t he fo llow ing funct ions:
• It blinks while you are driving when the ESP is working .
• It illumina tes when yo u sw itch on the ignition for approximate ly 2
seconds as a funct ion check.
• It ill uminates when the re is a malfunct ion in the ESP. T he
message
ESP fault! See owner's manual a lso appears in the instru­
ment cl uste r display and a w arning tone sounds.
• It illuminates continuously when the ESP is sw itched off.
• It illum inates if the re is a malfu nction in the ABS, s ince the ESP is
part of the ABS system .
If the battery terminals were disconnected and re- connec ted, the
vehicle was jump started or the battery is very weak, the ESP sensor
system goes thro ugh a learning process for the firs t few yards . The
warning/indicator light illuminates. The warn ing/indicator light goes
out as soon as t he learning process is comp lete.
If the ESP warning/i ndicator lig ht ill uminates and stays on afte r you
have started the engine, t his may mean that the control system has
temporar ily switched off the ESP . If this is case , you ca n react ivate
the ESP by turning the ignition off and then on aga in. The
