.&_ 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
(+S 0
().
-Always remember, even if the "snow­
flake" symbol (ice warning) does not ap­
pear 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.
@ Tips
- If the vehicle is stationary, or if you are
driving at a very low speed, the tempera­
ture shown in the display might be
slightly higher than the actual outside
temperature. This is caused by the heat
being radiated from the engine.
- On vehicles with Audi Nav igation sys­
tem*, the displays may differ from their
normal appearance during navigation.

On-Board Diagnostic
system (OBD)
On-Board Diagnostics
Fig. 25 Locat ion of Data Link Connecto r (DLC)
On-Board Diagnostics monitors the compo­
nents of you r emission control system. Each
monitored compo nen t in your eng ine system
has been assigned a code . In case of a ma l­
function, the component will be identified
and the fau lt stored as a code in the control
module memory.
The MIL light may a lso illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem .
If the light illuminates after a refuelling,
stop the vehicle and make sure the fuel filler
cap is properly closed ¢
page 176.
In o rder to make an accurate diagnosis, the
stored data can only be displayed using spe­
cia l diagnostic equipment (generic scan tool
for OBD).
I n o rder 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. 25.
Your authorized Audi dea ler or a qualified
service station can interpret the code and per­
form the necessary repair .
Malfunction Indicator lamp (MIL)

part of the On-Board Diagnostic COBO II) sys­
tem .
The warning/indicator light illuminates when
the ignit io n is switched on and goes out after
the e ngine starts and the idle has stabilized.
Th is indicates that the MIL is working prope r­

tem.
If the light illum inates, the catalytic con­
verte r could be damaged .
Continue driving
with reduced p ower (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact you r authorized Audi dea le r.
If the light illum inates, the electronic speed
limi ter may also be malfunct ioning . For more

Electronic speed limiter
Your vehicle may be factory eq uipped 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 fai lure and loss of control if
the vehicle is operated at excessive speeds,
your vehicle a lso has an electronic speed limit­
er . The electronic speed limiter prevents your
vehicle from going faster than the tire speed
rating. Fo r more information
