Auto Check Control
Some functions and vehicle components are
scanned for their operating status when you
switch the ignition on and whi le you are driv­
ing . Malfunctions or required service proce­
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 , espec ially br idges
and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F (+S °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 conditions
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 slightly
higher than the actual outside tempera­
ture. This i.s caused by the heat being radi­
ated from the engine .

-The information in the Service Reminder
remains stored even when the vehicle
battery is disconnected .
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 Diagnostic (080 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 whi le you are driv­
ing, a malfunction may exist in the engine 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 condition corrected.
Contact your authorized Audi dealer .
If the light illuminates, the electronic speed
limiter may also be malfunctioning. For more
information ¢ page 29, Electronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
¢page 204.
On-Board Diagnostics
Fig . 16 Locat ion of Data Link Connector (DLC)
Driver information display 29
On-Board Diagnostics monitors the compo­
nents of your emission contro l 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
~ page 204.
In order to make an accurate diagnosis, the
stored data can on ly be displayed using spe ­
c ial diagnostic equipment (generic scan tool
for 080).
In order to connect the special diagnostic
equipment, push the plug into the Data Link
Co nnector (DLC) . The DLC is located to the
right of the hood release ¢ fig . 16 .
Your authorized Audi dealer or qualified work­
shop can interpret the code and perform the necessary repair.
A WARNING u:;
Do not use the diagnostic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a collision!
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 may be less than
the maximum speed of your vehicle. To reduce
the risk of sudden tire failure and loss of con­
trol if the vehicle is operated at excessive
speeds, your vehicle has an electron ic speed
limiter . The electronic speed limiter prevents
your vehicle from go ing faster than the tire
speed rating. For more information
