Driver information display
& 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
hood open
With the ignition switched on, the open-door-or-lid warning illumi­
nates when at least
one door, or the engine hood or the trunk lid is
not closed . The symbol also shows you which door(s) or lid is not
closed. The illustration shows that both the driver's and the right
rear door are not closed
:::::, fig. 14.
If the engine hood or trunk lid are not closed, the display will flash.
As soon as all the doors and lids are properly closed, the warning
goes out.
~

You can switch off the open-door-or-lid warning display by briefly pressing the On Board computer control
but tons => page 39. The
open door or trunk warn ing will, however, illuminate again as soon
as there is a change in the position of the doors, engine hood or
trunk lid. •
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
information=> page 28, "Electronic speed
limiter".

On-Board Diagnostics monitors the components of your emission
control system . Each control led component in your engine system
has been assigned a code. In case of a malfunction, the component
wil l be identified and the fault stored as a code in the control
modu le memory.
The M IL lamp may a lso illuminate if there is a leak in the on-board
fuel vapor recovery system. If the light illuminates after a refuelling,
pull off the road and stop the vehicle, then check that the fuel fi ller

In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnos tic equipment (generic scan tool for
OBD).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is located to the right of
the engine hood release

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.

Whenever the ignition is turned on, Auto -Check Control checks the
proper functioning of important vehicle components and systems.
Auto -Check Contro l keeps up its continuous monitoring of vehic le
systems even as you are driving.
If Auto Check senses an irregular condition or a malfunction
requiring urgent repair, it generates a specific symbol or short
message in the instrument cluster center display . You will also hear
an audible warning tone . The disp lays a re color coded in either red
or yellow depending on their level of priority.
A red symbol means
D anger , a yellow symbol indicates Warning .
Along with some particular red symbols, a message will appear in
the display to alert the driver to certain conditions. •

Driver information messages
Along with some particular warning/indicator lights and instrument cluster symbols, additional messages will
appear in the display .
A driver information message will appear in the display when, for
example :
a light bulb has burnt
out => page 35,
or if you drive off with the parking brake s till engaged (pulled up).
or before you move the selector lever in gear (automatic transmis­
sion).
Driver information messages can be switched o n by the driver when
a priority 1 symbol appears and flashes =>

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.
Setting speed warning 1

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 .

[ i ] Tip s
Even though your vehicle is equipped with a speed warning system,
you shou ld still watch the speedometer to make sure you are not
driving faster than the speed l imit. •
