following functions: •
It illuminates for a few seconds after the ignition is turned on as
function check and then goes out.
• If the warning/ind icator light illuminates steadi ly, there is a

Driver information display
If the vehicle is stationary, or if you are driv ing at a very low speed, the
temperature shown in the display might be slightly higher than the
actual outside temperature. This is caused by the heat being radiated
from the engine.
If you have selected the °C (degrees Celsius) unit for temperature in
the
MM I, the outside temperature display a lso appears automatically
in
°C.
& 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 (+5 °C).
• Always remember, even if the "snowflake " symbol (ice
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. •

On-Board Diagnostics
Fig. 15 Location of
Data Link Connector
(OLC)
On-Board Diagnostics monitors the components of your emission
control system. Each mon itored 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 illum inate if there is a leak i n the on-board fuel
vapor recovery system.
If the light illuminates after a refuelling, stop
the vehicle and make sure the fuel filler cap is properly closed
~page 285.
In order to make an accurate diagnosis, the stored data can only be
displayed using special d iagnostic equipment (generic scan too l 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 hood release~ fig. 15. Your authorized
Audi dealer or a qualified service station can inter­
pret the code and perform the necessary repair.•
Electronic speed limiter
Your vehicle may be factory equipp ed w ith 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 a lso 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 318.
If the eng ine control unit receives faulty vehicle road speed signals ,
the Malfunction Indicator Lamp (MIL) will illuminate. If this
occurs, contact the nearest a uthorized Aud i dealer for assistance.
& WARNING
Always observe the posted speed limits and adjust your speed to
suit prevailing road , traffic and weather conditions. Never drive
your vehicle faster than the maximum speed rating of the tires
i nstalled. •
