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
system fault in the Adaptive A ir Suspens ion. A system fault can result
in limited ride comfort and
low ground clearance. The fault should be
corrected as soon as possible by an authorized Audi dealer.
• If the warning/indicator light flashes, you should not drive the
vehicle . The flashing wa rning/ind icator light points to an extreme
H igh level. A very
pronounced lifting of the veh icle (extreme High
level) can resu lt, for examp le, when a heavy load is removed from the
vehicle . As soon as the level has returned to normal, the
warning/indicator light stops flashing, and you can drive away.
• If the warning/ind icator light flashes in conjunction with the~
wa rning/indicator light, you shou ld not drive off immediate ly in o rder
to prevent damage to the underbody . The two warning/indicator
lights flashing together points to an extreme Low level. A very
pronounced lowering of the veh icle (extreme Low level) can result,
for examp le, from a heavy load. As soon as the level has returned to
normal, the warning/indicator lights stop flash ing, and you can drive
away .

Informat ion from the Driver Information System is shown in the
display in the center of the instrument cluster.
When you tu rn on the ign ition and while you are driving, some func­
tions and vehicle components are scanned for their operating status. Malfunctions or required service procedures are signalled audibly and
shown by red and yellow lighted symbols and reminders to the driver
in the display .
T he d river is a lso shown information about radio and CD operation
and directions for the navigation system. You can find additional
information on these subjec ts in the MMI manual.

m en t Vehicle
OP-eration
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. •
Auto Check Control
Introduction
The Auto-Check control monitors the funct io n of certain vehicle
features and components . It simply makes sure these features and
components are working properly. The Auto-Check control works as
long as the ignition is on, as well as whenever the vehicle is driven.
If a component is malfunctioning or if the need for an urgent repair
has been detected, this w ill appear in the instrument cluster display . .,,_
