Some f unctions and vehicle components are
scanned for their operating sta tus when yo u

A WARNING
-
- Never rely exclusively on the outside
temperature display to determine if a
road surface is icy o r not . Keep in m ind
th at r oad surfaces, espec ia lly br idges
and overpasses, co uld be ice covered and
slippery even at an outside tempe ratu re
above 41 ° F (+S °C).
- Always remember , even if the "snow­
f lake" symbo l (ice warning) does not ap­
pear in the d isp lay, black ice cou ld be on
the road .
- Always reduce your speed and drive with
special care in cold weather conditions
when the chance of encountering icy
road surfaces increases.
{I) Tips
If the vehicle is stationary, or if yo u a re
driving at a very lo w speed, the tempera­
ture shown in the display might be s light ly
higher than the actua l outs ide tempera­
ture. This is caused by the heat be ing radi­
ated from the engine .

26 Driver information d isplay
The values in the single -trip or the total-trip
memory can a ll be reset to zero at the same
time under
Reset in the menu.
I n addition, you can determine what informa­
tion from the trip computer should be shown
in the instrument cluster d isplay. If one of the
p ieces of driver information is turned
Off, that
driver information will not be shown in the
display. The information will continue to be
calculated by the trip computer and can be
turned back
On at any time .
@ Tips
-This function is not available on all
vehicles.
- The dr iving information in the efficiency
program is also reset to zero with the
s ingle-trip memory.
Gearshift Indicator
App lies to vehicles: with manua l transmission and gear­
shift indicator
This indicator can help conserve fuel.
F ig. 12 Disp lay : Gea rs hift indicator
In order to become familiar with the gearshift
indictor, at first just drive the way you are
used to. If the current gear -and the driving
situa tion -is not the best one for conserving
fuel, then the indicator will display the recom­
mended gear. The display shows the current
gear and the gear that is recommended
¢ fig. 12.
- Upshifting The display will light up to the
right of the gear currently se lected if it is
recommending a higher gear.
-Downshifting: The display will light up to
the
left of the gear currently selected if it is
recommend ing a lower gear.
Sometimes the indicator will recommend
skipping a gear (3
> S).
If there is no gearshift recommendation, then
j us t drive in the appropriate gear for conserv­
ing fuel.
(D Note
This indicator can help you conserve fuel.
This indicator is not meant to show you
which gear you should always be in in all
driving situations . Sometimes, in situa­
tions such as passing, driving through
mountains or when towing a trailer, there
won't be any gearshift recommendation.
@ Tips
The display does not light up when the
clutch pedal is being depressed.

Resetting the service interval display
Your authorized Audi dealer w ill rese t the cor­
responding service schedule after performing
the appropriate service on your vehicle. Yo u
also have the possibility to reset the oil
change schedule after having performed an
oil change according to Audi specifications.
Select
I CAR I function button > Service interval
display > Reset oil change interval
or !CARI
function button > Car systems* control but­
ton

0 Note
- Only reset the oil change d isplay when
you have completed an oil change.
-If you disconnect the battery terminals,
no calculat ions can be made for the serv­
ic e interval display during this tim e and
no service rem inder will appear. Remem­
ber that observing the proper service in­
terva ls is vitally important to extending
the life of your vehicle, particularly the
engine, and maintaining its va lue. Even if
the mileage dr iven is low, the max imum
period of one year from one serv ice to
the next must not be exceeded .
(D Tips
The informat ion in the Service Reminder
remains stored even when the vehicle bat­
tery is disconnected.
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
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 stabilized .
This indicates that the MIL is work ing proper­
l y.
Driver information display 29
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 ­
tem.
If the light illuminates, the catalytic con­
verter could be damaged.
Continue d rivin g
with reduced power (avoid­
ing su sta ined high speeds and/or rapid accel ­
erations) and have the cond ition corrected.
Contact your authorized Audi dealer.
If the light illuminates, the electronic speed
li miter may also be malfunct ioning. For more
information
c;,page 30, Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c:;, page 210.
On-Board Diagnostics
Fig. 18 Location of Data Link Connector (D LC)
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 memo ry .
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem. If the light illumi nates afte r a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed
¢ page 210.
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). .,.

30 Driver in formation d isplay
In o rder to connect the special diagnostic
equipment, push the plug i nto the Data Link
Connector (DLC) . The DLC is located to the
right of the hood release¢
fig. 18.
Your authorized A udi dealer or qualified work­
shop can interpret the code and perform the necessary repa ir .
.&_ WARNING
Do not use the diagnostic connector for
personal use. Incorrect usage can cause
ma lfunctions, which can increase the risk
of a coll is ion!
Electronic speed limiter -
Your veh
icle may be factory equipped with
tires that are rated for a maximum speed of 130 mph (210 km/h) . Thi s is m ay be less than
the maxim um speed of your ve hicle. To red uce
the r isk of sudden tire fail ure and loss of con­
trol if the vehicle is operated at excessive
speeds, yo ur vehicle has an e lectronic speed
limiter. The electronic speed limiter prevents
your ve hicle from going faster than the tire
speed rat ing. For more information

If the engine control unit rece ives fa ulty vehi­
cle roadspeed signa ls, the Ma lfunction Indica­
tor Light (MIL)
