At temperatures be low 41 °F (+5 °C), a snowflake symbol appears in
fr ont of t he te mp eratur e dis play . It is inte nded to remind the d river
to pay special attent ion to
ice on the road.
If your vehicle is stationa ry or if you are d riving at very low speeds,
th e te mpera ture d isplaye d may b e slig htly h igher t han the actu al

& WARNING
• Never use the outside temperature display to determine if a
road surfa ce is icy or not . Keep in mind that road surfa ces , espe ­
cially bridges and overpasses, could be ice covered and slippery
even at an outside temperature above 41
° F (+5 °C ).
• Always remember, even if the "snowflake " symbol (ice
wa rning) 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 in creases .
[ i ] Tip s
• I f the vehic le is stationary , or if you are driving at a very low
speed, the temperature shown in the d isplay migh t be slightly
h ig her than the actual outside temperature. This is caused by the
heat being radia ted from the engine .•

On-Board Diagnostic system (08D)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=> page 12, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
The warning/ind icator light illuminates when the ignition is
switched on and goes out after the engine starts and the id le has
stabi lized. This indicates that the MIL is working proper ly .
If the light does not go out after the engine is started, or illuminates
while you are driving, a ma lfunction may exist in the engine system.
If the light illuminates, 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 23, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
=> page 267. •
On-Board Diagnostics

On-Board Diagnostics monitors the components of your emission
control system. Each monitored component in your engine system
has been assigned a code. In case of a malfunction, the component
will be identified and the fault stored as a code in the control
module memory.
The MIL light may also illuminate if there is a leak in the on -board
fuel vapor recovery system. If the light illuminates after a refueling,
stop the vehicle and make sure the fuel filler cap is properly closed
=> page 267.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBDl.
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 hood release=>
page 22, fig. 17.
Your authorized Audi dealer or qualified workshop can interpret the
code and perform the necessary repair. •
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 vehicle from going faster than the
tire speed rating. For more information=>
page 299.
If the engine control unit receives faulty vehicle road speed signals,
the Malfunction Indicator Lamp (MIU will illuminate. If this
occurs, contact the nearest authorized Audi dealer for assistance.

Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
The speed warning system warns if the driver exceeds a previously stored maximum speed . A warning tone wi ll sound as soon as the
vehicle speed exceeds the set speed by about 3 mph (3 km/h) . At the
same time, a warning symbol appea rs in the display. The symbol's
appearance might be different in some models.
The speed warning system has
t w o wa rning thr esholds that func ­
tion independent ly o f each other and that have somewha t di fferent
purposes:
S p eed war ning 1
You can use speed warning 1 to set the maximum speed while you
are driving. This setting will remain in effect un til you turn off the
ignition, assuming that you have not changed or res et the setting.
The speed warning symbol
8 (USA mode ls)/ 8 (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 . T
he speed warning symbol wi ll 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 deleted.
Setting speed warning 1
::;> page 26 .
S peed w arning 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 general maximum speed limit, or if you do not
want to exceed a specified speed for winter tires.
T he speed warning 2 symbol,
8 , (USA models)/ 0 (Canada models)
appears in the display when you exceed the stored speed limit .
Un like warning 1, it wi ll not go out until the vehic le speed drops
b el ow the stored speed limi t.
