scanned for their operating status when yo u
switch the ignition on and whi le you are driving.
Malfunctions or required service procedures are
signaled audibly and indicated by red and yellow
illuminated symbols and reminders in the dis­
play.
A WARNING
--- Never rely exclusively on the outside tem­ pe ratu re d isplay to dete rm ine if a road sur­
face is icy or not. Keep in mind that road sur­
faces, espe cially bridges and overpasses,
could be ice covered and slippery even at an
outside temperature above 41 °f (+S °C).
- Always remember, even if the "snowflake"
symbo l (ice warning) does not appear in the
display, black ice cou ld be on the road .
-Always red uce your speed and d rive with
specia l care in cold weather conditions when
the chance of encountering icy road surfaces
increases.
(j) Tips
If the vehicle is stationary, or if yo u are driv­
ing at a very low speed, the temperature
shown in the disp lay might be slightly higher
than the actual outside temperature . This is
caused by the heat being radiated from the
engine.

On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢-4 in the
instrument cluster is part of the On-Board Diag ­
nostic (OBD II) system.
The warning/indicator light illuminates when the
ignition is switched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates that the MIL is working properly.
If the light does not go out after the engine is
started, or illuminates while you are driving, a malfunct ion may exist in the engine system. If
the light illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained high speeds and/or rapid accelerations)

and have the condition corrected. Contact your
authorized Audi dea ler.
If t he light illuminates, the electronic speed lim­
ite r may also be ma lf u nctioning. For more infor­
mation

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

On-Board Diagnostics
Fig. 18 Locat ion of Data Link Connector (DLC)
On-Board D iagnost ics monitors the components
of your emission control system. Each monito red
component in your engine system has been as­
signed a code. In case of a malfunction, the com­
ponent will be ident ified and the fault stored as a
code in the control module memory.
T he MIL light may also illum inate if there is a
leak in the on-board fuel vapo r recovery system .
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed
