A 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
slippe ry even at an outside temperature
above 41 °F (+S °C).
- Always remember, even if the "snow­
flake" symbo l (ice warning) does not ap­
pear in the d isp lay, black ice cou ld be on
the road.
- Always reduce your speed and drive with
specia l care in cold weather conditions
when the chance of encountering icy
road surfaces increases.
(D Tips
- At temperatures below 14 °F (+ 5 °C) a
snowf lake symbol appears ahead of the
temperature display. It is intended to re­
mind the driver to pay special attention
to
ice on the road c:> .&.. If the vehicle is
stationary, or if you are driving at a very
low speed, the temperature shown in the
display might be slightly h igher than the
actual outside temperature. This is
caused by the heat being radiated from
th e engine.

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ISi in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illumina tes when
the ignition is switched on and goes o ut after
the engine starts and the idle has stabi lized.
This indicates that the MIL is work ing proper­
ly.
If the light does not go out after t he engine
is started, or illuminates while you are driv ­
i ng, a mal function may e xist in the eng ine sys ­
tem.
If the light illumi nates, the catalytic con­
verter could be damaged .
Contin ue d riving
with reduced power (avoid­
i ng s usta ined h igh speeds and/or rapid accel ­
erations) and have the cond ition corrected .
Contact your a uthorized Audi dea ler.
If the light illuminates, the e lectronic speed
li miter may also be malfunct ion ing. For more
i nformation ¢
page 2 8, Electronic speed
limiter.
An improperl y closed fuel filler cap may also
cause the MIL light to illuminate

On-Board Diagnostics
Fig. 15 Location of Data Li nk Co nnector (D LC)
On-Boa rd Diagnost ics monitors the compo ­
nents of your em issio n cont ro l system . Eac h
monitored component in your engine system
has been assigned a code. In case of a mal ­
functio n, the component will be identified
and t he fault stored as a code in the control
module memo ry .
The MIL light may also illuminate if there is a leak in the on-board f uel vapor recovery sys­
tem. If the lig ht illum inates afte r a refuelling,
stop the vehicle a nd make sure the fuel fille r
cap is properly closed
¢ page 213.
In order to make an accurate diagnosis , the
stored data can o nly be disp layed using spe­
c ial diagnostic equipment (generic scan tool

28 Instruments and warning/indicator lights
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 interpret the code and per­
form 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 limit­
er. The electronic speed limiter prevents your
vehicle from going faster than the tire speed rating. For more information
c::> page 242.
If the engine control unit receives faulty vehi­
cle road speed signals, the Malfunction Indi­
cator Lamp (MIL)
II will illuminate. If this
occurs, contact the nearest authori zed Audi
dealer for assistance.
A 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 maxi­
mum speed rating of the tires installed.
