n,/{J Electronic Stabilization Control
(ESC)
If the G1 indicator lamp blinks while driving,
the ESC or ASR (Ant i-S lip Regulation) is active­
ly regulating.
If the G1 indicator lamp illuminates, the sys­
tem has switched the ESC off. In this case , you
can switch the ignition off and then on to
sw itch the ESC on again . The system is func­
tioning completely when the indicator lamp
switches off .
I f the

dures are signaled audibly and indicated by
red and yellow illuminated symbols and re­
minders in the d isplay.
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) II in
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 stabi lized .
This indicates that the MIL is working proper­
l y.
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 engine sys- tern.
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 condition corrected.
Contact your authorized Audi dea ler.
If the light illuminates, the electronic speed
limiter may also be malfunct ioning. For more
information
q page 31, El ectronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
~page 212.
On-Board Diagnostics
Fig. 18 Locat ion of Data L ink Connector (DLC)
On-Board Diagnostics monitors the compo­
nents of your em ission control system . Each
monitored component in your engine system
has been assigned a code . In case o f a mal­
function, the component will be identified
and the fault stored as a code in the control
module memory.
T he 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
q page 212.
In order to make an accurate diagnosis, the
stored data can on ly be displayed using spe ­
cial diagnostic equipment (generic scan tool
for OBD).
In order to connect the special diagnostic
equipment, push the plug into the Data Link ..,.
