A WARNING
-
-Never rely exclus ively 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 "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.
(1) Tips
- At temperatures below 14 °F (+ 5 °() a
snowf lake symbol appears ahead of the
temperature display. It is intended to re­ m ind the driver to pay special attention
to
ice on the road <::;> .&,. If the vehicle is
stationa ry, or if you are driving at a very
low speed, the temperature shown in the
display might be slightly hig her than the
actual outside temperature. This is
caused by the heat being radiated from
the engine .
- You can select the units used for temper­
ature, speed and other measurements in
the MMI.
- For information on the audio/video and
navigation* functions, refer to the sepa­
rate MMI owner's manua l.

the engine starts and the idle has stabilized.
This indicates that the MIL is working proper­
ly.
If the light does not go out after the engine
i s started, or illuminates whi le you are driv­
ing, a ma lfunction may exist in the engine sys­
tem .
If the light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing susta ined high speeds and/or rapid accel­
erat ions) and have the condition corrected.
Contact your authori zed Audi dealer .
If the light illuminates, the electronic speed
limiter may also be ma lfunctioning. For more
information

limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate

On-Board Diagnostics
Fig . 16 Locat io n of Data Link Co nnector (D LC)
On-Board Diagnostics monitors the compo­
nents o f your emission control system. Each
monitored component in your engine system
has been assigned a code. In case of a mal­
function, the component will be identified
and the fault 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 veh icle and make sure the fuel filler
cap is properly closed
Q page 22 7. In order to make an accurate diagnosis, the
stored data can on
ly be displayed using spe­
c ial diagnostic equipment (generic scan tool
for OBD).
In order to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (D LC). The DLC is located to the
right of the hood release~
fig. 16.
Your authorized Audi dea ler or a qualified
service station can interpret the code and per­
form the necessary repair.
A WARNING
-Do not use the diagnostic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a collision!
Electronic speed limiter
-
Your vehicle may be factory equipped w ith
t ir es 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 also has an e lectronic speed limit­
er . The electronic speed limiter prevents your
vehicle from going faster than the tire speed
rating . For more information
Q page 257.
If the engine control unit receives faulty vehi­
cle road speed signals, the Malfunction Indi­
cator Lamp (MIL)
¢fj will illuminate . If this
occurs, contact the nearest authorized Audi
dealer for assistance.
S models
Your vehicle's top speed is electronica lly limit­
ed to 155 mph (250 km/h).
If the engine control unit receives faulty vehi­
cle roadspeed signals, the Malfunction Indica­
tor Lamp (MIU¢.§ will illuminate . If this oc­
