Electronic Stabilization Program (ESP) fJ
The warning/indicator ligh t monit ors the electr onic s tabi ­
lization program.
The ~ warning/indicator light has the fol lowing functions:
• it flashes while you are driving, when the ESP is working .
• it illuminates when you switch on the ignition for approximately
2 seconds as a funct ion check.
• it illuminates when there is a ma lfunction in the ESP.
• it illuminates after the battery has been disconnected .
• it illuminates continuous ly when the ESP is switched off . •
it illuminates if there is a malfunction in the ABS, since the ESP
is part o f the ABS system.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine, this may mean that the control system has
temporar ily switched o ff the ESP . If this is case, you can reactivate
the ESP by switching the ignition off and then on again . The
warning/indicator light should go out to show that the system is
ful ly functional again .
I f the battery terminals were disconnected and re -connected, the
vehic le was jump started or the battery is very weak, the ESP sensor
system goes through a learning p rocess for the firs t few yards.
D uring th is time, t he ind icator l ight i llu minates. It goes out as soo n
as the learning process is comp lete.

Outside temperature display
F ig. 12 Ce nter disp lay:
o utside te mperature
The outside temperature wil l be displayed when you switch on the
ignition~ fig . 12. If your vehicle has an Automatic transmission, the
outside temperature will appear in the disp lay only after you have
moved the selector lever into a gear (for example, when you shift
into
" D "l.
The snowflake symbo l also appears when the outside temperature
is between 41 °F (+5 °Cl and 23 °F (-5 °Cl. This is to warn you, the
driver, to be extra cautious because the road surfaces may be
ic y. If
the vehicle is at a standstill, or if you are driving at a very low speed,
the tempe rature shown in the display might be s lightly higher than
the actual outside temperature. This is caused by the heat being
radiated from the engine.
Remember, your vehicle is equipped with air conditioning and if
you change the display from °F (Fahrenheit) to °C (Centigrade), then
the outside temperature will automatically be displayed in °C (Centi -
grade)~ page 128. ...

& WARNING
• Never rely exclusively on the outside temperature display to
determine if a road surface is icy or not. Keep in mind that road
surfaces, especially bridges and overpasses, could be ice covered
and slippery even at an outside temperature above 41 °F
1+5 °Cl.
• Always remember, even if the "snowflake" symbol lice
warning) does not appear in the display, black ice could be on the
road .
• Always reduce your speed and drive with special care in cold
weather conditions when the chance of encountering icy road
surfaces increases.
[ i ] Tips
When using the navigation system feature "Destination", the
outside temperature is also displayed.•
Miles (kilometers) to empty
The miles (kilometers) to empty indication is a valuable
aid to schedule the refueling stops on a trip.
Fig . 13 Center display:
miles (kilometers) to
empty
Th is feature shows you the estimated range in miles (kilometers)
:::::, fig. 13 until the tank runs dry. This feature calculates how far you
could drive with the amount of fuel left in your fuel tank while
driving under the current driving conditions. The remaining
distance is recalculated every
6 miles (10 km).
While calculating the miles (kilometers) to empty, the system also
calculates your fuel consumption over the last
18 miles (30 km).
Remember:
-the more economica lly you drive, the further you can
go.•
Warning : engine hood, door or rear lid open
Fig . 14 Display: door ,
rear lid, and engine

On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL) (USA
models) / (Canada models)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=> page 19, fig. 9 is part of the On -Board Diagnostic (OBD II) system.
The warning/indicator light il luminates when the ignition is
switched on and goes out after the engine starts and the idle has
stabi lized . This indicates that the MIL is working prope rly.
If the light do es 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
w ith redu ced pow er (avoiding sustained high
speeds and/or rapid accelerations) and have the condition
corrected. Contact your authorized Audi dealer.
If the light illuminates, the e lectronic speed limiter may also be
malfunctioning . For more

Electronic speed limiter
Your vehicle may be factory equipped with tires that are rated for a
maximum speed of 130 mph (210 km/h}. This is less than the
maximum speed of your vehicle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operated at excessive speeds, your vehicle also has an electronic speed limiter . The elec ­
tronic speed limiter prevents your vehic le from going faster than the
tire speed rating. For more
information~ page 305, "New tires and
r eplacing tires and wheels" .
If the vehicle approaches the tire speed rating, the engine control
unit wi ll turn off the fuel injectors. You will notice an immediate loss
of engine power and a drop in road speed.
If the engine control unit receives faulty vehicle road speed signals,
t he Malfunc tion Indicator Light (MIU will illuminate. If this occurs,
contact the nearest authorized Audi dea ler for ass istance.

Driver inf orma tion di spl ay
The speed warning system warns the driver if he exceeds a previ­
ously stored maximum speed . A warning tone wi ll sound as soon as
the vehic le speed exceeds the set speed by about 6 miles per hour
(10 km/h) . At the same time, a warning symbol appears in the
display~ fig. 21 .
The speed warning system has
t wo wa rning thre sholds that func ­
tion independent ly of each other and that have somewhat different
purposes:
Sp eed w arnin g 1 -
You can use speed warning 1 to set the maximum speed while you
are driving . This setting will remain in effect until you turn off the
ignition, assuming that you have not changed or reset the setting.
The speed warning symbol (USA models)/ (: (Canada models) in
the warning 1 disp lay appears when you exceed the maximum
speed. It goes out when the speed falls be low the stored maximum
speed .
The speed warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed is de leted.

S pee d w arni ng 2
Storing warning 2 is recommended if you always want to be
reminded of a certain speed, for example when you are traveling in
a country that has a genera l maximum speed limit, or if you do not
want to exceed a specified speed for winter tires.
The speed warning 2 symbol, (USA models)/ (Canada models) appears in the disp lay when you exceed the stored speed limit .
Unlike warning 1, it wil l not go out until the vehicle speed drops
below the stored speed limit .
