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 br idges
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 disp lay, black ice cou ld be on
the road.
- Always reduce your speed and drive with
specia l care in cold weather cond itions
when the chance of encountering icy
road surfaces increases.
¢j) 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 s light ly
higher than the actual outs ide tempera­
ture. This i.s caused by the heat being radi­
ated from the engine .

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) (4 i n
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes out after
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
is started, or illuminates while you are driv­
ing, a malfunction may exist in the eng ine sys­
tem . If the light illuminates, the catalytic con­
verter could be damaged .
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact your authorized Audi dealer.
If the light illuminates, the electronic speed
limiter may also be malfunct ioning. For more
information
c:> page 31 , Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the
MIL light to illuminate
c:>page 217.
On-Board Diagnostics
Fig. 18 Locat io n of Data Link Con nector (D LC)
On-Board Diagnostics monitors the compo­
nents of 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 also illuminate if there is a leak in the on-board fuel vapor recovery sys­
tem. If the light illuminates after a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed

In order to make an accurate diagnosis, the
stored data can on ly be displayed using spe­
c ial diagnostic equipment (generic scan tool
