This warning/indicator light monitors the electronic
power control.
The warning/indicator light (E lectronic 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 malfunction in the engine electronics . Have the malfunc ­
tion corrected as soon as possible by your authorized Audi dealer or
qualified repair faci lity .•

0 Note
If the _f_ warning/indicator light (malfunction in the engine coo ling
system) in the instrument cluster shou ld illuminate=>
page 33, stop
the vehicle and turn off the engine . The water pump is not work ing
- this can cause engine damage. •
Electronic stabilization program (ESP)
This warning/indicator light monitors the electronic stabi ­
lization program.
The warning/indicator light has the following functions:
• I t blinks while you are driving when the ESP is working.
• It illuminates when you switch on the ignition for approximately
2 seconds as a function check.
• It il luminates when there is a malfunction in the ESP.
• It illuminates when ESP or ASR (Anti-S lip Regulation) is deacti­
vated .
• 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
vehicle was jump started or the battery is
very weak, the ESP sensor
system goes through a learning process for the first few yards. The
warning/indicator light i lluminates . 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
te mporarily switched off the ESP. If this is case, you can reactivate
the ESP by turning the ignition off and then on again . The
warning/indicator light should go out to show that the system is
fully functional again.

<£> For th e sak e of th e environm ent
Driving w ith under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tip s
• Each tire, incl udin g the sp are, should be checked monthly when
cold and set to the recommended inflation pressure as specified on
the tire pressure label=>
page 317.
• The factory supplied spare whee l is equipped with a sensor for
the tire pressure monitoring system. As long as the spare whee l it
not mounted, the tire pressure of this tire will not be monitored.
• The tire pressure monitoring system he lps the driver to keep an
eye on t ire pressures. But the driver stil l has the responsibility for
maintaining the correct tire pressure.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature .
• When tires are replaced, the sensors and valves shou ld not be
detached or exchanged. Only the valve core needs to be rep laced
and, i f necessary, the valve and the wheel electronics replaced.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire p ressure monitoring system.
Otherwise the system w ill register a ma lfunction and a fault
message will be displayed . For more information, contact your Audi
dea ler.
• Adjust the tire pressure and store the pressure in the tire pres­
sure monitor ing system to the load you are carry ing. •

A ll pressure warning and system malfunction indicators in the
display will be canceled.
If a wheel change has been made, it is necessary to complete the
Initi alize w heel s function . After you have selected the function, the

Syste m malfu nc tion
If the warning light in the instrument cluster flashes for approxi­
mately one minute and then remains continuously il luminated and
additionally the
JIS => fig . 28 symbol appears in the display , the
tire pressure monitoring system is not available. This can have
various causes.
• If the message appears at the end of the learning process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a whee l sensor were
insta lled .
• A wheel sensor or other component may have failed .
• During initialization the system has detected more than 4 whee ls
on the vehicle, for examp le while driving next to another car with a
tire pressure monitoring system .
• A wheel change was made but the Initialize wheel s function
=> page 46was not activated.
• Audi replacement parts were not used .
• I f snow chains are being used , system function can be compro ­
m ised due to the shielding properties of the cha ins .
• T he tire pressure monitoring system may not be available
because of a radio ma lfunction.

• Transmitters with the same frequency, such as radio head­
phones in the veh ic le or radio equipment, can cause a temporary
disruption of the system through excessive electromagnetic fields.
• Eliminate the interference if possib le/if you can and then re-start
the
Init ialize wh eels function . If the warning light comes on again,
you shou ld contact your authorized Audi dealer immediate ly to have
the problem corrected.
• Do not use commercially available tire sealants. Otherwise, the
e lectrical components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni ­
toring system wi ll have to be replaced by a qua lified workshop .•
