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 ¢

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

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.
