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 .•
Generator 0
This warning/indicator light detects a malfunction in the
generator or in the vehicle's electrical system.
The d warning/indicator light illuminates when you switch on the
ign ition and mus t go out after the engine has started .
If the
d warning/indicator light illuminates while you are driving,
you shou ld contact your authorized Audi dealer. Since the vehicle
Controls and equip ­
ment
Instruments and warning /indi cator lights
battery is discharging, you shou ld switch off any unnecessary elec ­
trical consumers (for examp le, the air conditioner).
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.

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 (MIU -in the instrument cluster
=> page 17, 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 authorized Audi dealer.
If the light illuminates , the electronic speed limiter may also be
malfunctioning . For more information =>
page 30, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate

Driver informati on displ ay
Trip computer
Introduction
The trip computer gives you informati on on current and
average fuel mileage, average speed, fuel range and
driving time.
F ig. 22 T rip compu te r
di spl ay: Ave ra ge f uel
mil eage
The fol lowing driving information is continuously evaluated by the
t rip computer and can be displayed sequential ly in the instrument
cluster display.
Fuel r ang e
The estimated cruising range in miles (km) appears in the display.
This tells you how far your vehicle will be able to trave l on the
current tank of fuel and with the same driving sty le. The display
changes in increments of 6 miles (10 km).
The cruising range is ca lculated based on the fuel consumption for
the last 18 miles (30 km). If you drive conservatively, the cruising
range will increase .
Avera ge fu el mil eage
The average fuel economy in MPG (1/100 km) since you last cleared
the memory appears in this display. You can use this display to
adjust your driving technique to achieve a desired mileage.
C urr en t fu el mi leage
The instantaneous fuel consumption in m iles per gallon (1/ 100 km)
is shown in this disp lay. You can use this display to adjust your
driving technique to achieve a desired mileage .
Fuel consumption is recalculated at interva ls of 33 yards (30
meters) . When the vehicle is stationary, the most recent fuel
consumption is displayed .
Averag e sp eed
The average speed in mph (km/h) since the last time the display was
reset appears in the display.
E la psed time
The length of time that you have been driving since you last reset
the memory appears in this display.
[ i ] Tips
• Fuel consumptions (average and current), range and speed are
displayed in metric units on Canadian models .
• All stored values will be lost if the vehicle battery is
disconnected. •

Driver information display
In addition, all the values in the single -trip or the total -trip memory
can be deleted simultaneously.
[ i ] Tips
All stored values will be lost if the vehicle battery is disconnected. •
MMI settings
Basic settings for the trip computer can be made in the
MM/.
Fig. 25 MMI display :

driving information from the trip computer shou ld be shown in the
instrument cluster display . If one of the pieces of driver information
is turned
off, that driver in formation will not be shown in the display.
The information will continue to be calculated by the trip computer
and can be turned back
on at any time. •
Tire pressure monitoring system
General notes
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significantly
under-inflated . The TPMS on ly provides a low tire pressure warning
and does not reinflate your tires .
Accordingly, when the low tire pressure telltale illumin ates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under ­
inflated tire causes the tire to overheat and can lead to tire failure.
Under -inflation also reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping ability .
0 Note
• Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver's responsibility to maintain correct
tire pressure, even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure telltale. .,,_

effective range depends on severa l things . Remember, if the battery
is weak, the effect ive range decreases.
I f you need to replace the remote co ntro l, or if you need to have it
repaired , you must see your authorized Audi dealer. Only then can
you use the key again .
Person alizing the m ast er key
When the ignition is tu rned off or when the vehicle is locked, various
convenience settings are stored automatical ly and assigned to the
key that was used . The settings that are assigned to the master key
are recalled automatically when the veh icle is unlocked, when the
door is opened or when the ignition is switched on .
Settings are saved for the fo llowing systems:
• Climate contro l
• Central locki ng
Con tro ls and eq uip­
ment
Op ening and clo sing
• Ambient lighting
• Windows
• Acoustic Parking System*
• Seat memory *
The
Remot e control ke y function must be activated in the MMI
~ page 92, so that the se ttings for the driver's seat (including the
settings for the ste ering column and exterior mirrors) are saved on
t he master key through the sea t memory when the vehicle is locked,
and are set automatica lly when the vehicle is unlocked .
[ i ] Tips
• I f the ignition is switched on, the remote control system is deac­
t ivated.
• The remote control syst em can be affected by other syst ems
operating in the same frequency range close t o the vehicle, such as
