Introduction
The Driver information display inside the instru­
ment cluster provides you, the driver, with im­
portant information.
Fig. 7 Instrument cluster: ce nter display

Center display
With the ignition on, the display in th e Driver In­
formation System shows the following informa­
tion :

Auto Check Control
Some functions and vehicle components are
scanned for their operating status when you
switch the ignition on and while you are driving. Malfunctions or required service procedures are
signaled audibly and indicated by red and yellow
illum inated symbols and reminders in the dis­
play.
A WARNING
--
- Never rely exclus ively on the outside tem­
pe rature display to determine if a road sur­
face is icy or not. Keep in m ind 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
display, black ice could be on the road.
- Always reduce your speed and dr ive 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 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.

¢page 26.
Single-trip memory (Trip computer 1)
The single-trip memory stores the trip informa­
tion from the time the ignition is turned on until
it is turned off.
If the trip is continued within 2
hours
from the time the ignition was turned off,
the new data w ill be included in the calculat ion of
the current tr ip inf ormat ion . If the trip is inter ­
rupted fo r
more than 2 hours the memory is re­
set automat ica lly.
Total-trip memory (Trip computer 2)
Unlike the single-trip memory, the total-trip
memory is not reset automatically. This permits
you to evaluate your driving data for the entire period between manual resets.
Efficiency program*
The efficiency program can help you to use less
fuel¢

On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ift 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 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 dealer.
If the light illuminates, the electronic speed lim­iter may also be malfunctioning. For more infor­
mation
¢ page 29, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate ¢
page 200.

On-Board Diagnostics
Fig. 17 Loca tion of Data Link Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code. In case of a malfunction, the com­
ponent 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 system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel f iller cap is prop­
erly closed
¢ page 200.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (gener ic scan tool for OBD).
In order to connect the special d iagnost ic equip­
ment, push the p lug into the Data L ink Connector
(DLC). The DLC is located to the right of the hood
release
¢ fig. 17.
Your authorized Audi dealer or qualified work­
shop can interpret the code and perform the nec­
essary repair.
.&, WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a co lli­
sion!
