_& WARNING
--Never rely exclusively on the outside tem­
perature display to determine if a road sur­
face is icy or not. Keep in mind that road
surfaces, especially bridges and overpasses,
could be ice covered and slippery even at an
outside temperat ure above 41 °F (+S °C).
- Always remember, even if the "snowflake"
symbol (ice warning) does not appear in the
d isp lay, black ice could be on the road.
- Always reduce your speed and drive with specia l care in co ld weather conditions when
the chance of encountering icy road surfaces
increases .
(0 Tips
- If the vehicle is stationary, or if you are driv­
ing at a very low speed, the temperature
shown in the display might be slightly high­
er than the actual outside temperature . This
is caused by the heat being radiated from
the engine . .,..

The short-term memory collects driving informa­
tion from the time the ignition is sw itched on un­
til it is switched off. If you cont inue driv ing with­
in two hours after switching the ignition off, the
new values are included when calculat ing the cur­

Fuel consumption
The current fuel consumption can be displayed
using a bar ~
fig. 8. The average consumpt ion
(mpg) stored in the short-term memory is also
displayed . When the bar turns green, your veh icle
saves fuel by one of the following functions:
-Recuperation : When the vehicle is coasting or
driving downhill, electrical ene rgy can be stor­
ed in the battery. The bar will move toward D.

On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ifi in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system .
The warning/indicator light illuminates when the
ignit ion 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 wh ile you are driving, a
28
malfunction 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 accelera­
tions) and have the condition corrected . Contact
your authorized Audi dea ler.
If t he light illuminates, the electronic speed lim­
iter may also be ma lfunctioning. For more infor­
mation ¢

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

On-Board Diagnostics
Fig. 16 Loca tion of Data Link Connector (DLC)
On-Boa rd Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s ig ned a code . In case o f a malfunct ion, the com­
pon ent will be identified and the fault stored as a
code in the contro l module memory.
The MIL light may also illum inate if there is a
leak in the on-boa rd fuel vapor recovery system.
If the light illuminates after a refuelling, stop
the vehicle and make sure the fuel filler cap is properly closed

In order to make an accu rate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for OBD) .
