_& 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 bridges
and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F
(+5 °() .
- Always remember, even if the "snow­
flake" symbol (ice warning) does not ap­
pear in the d isplay, black ice could be on
the road .
- Always reduce your speed and drive with special care in cold weather cond itions
when the chance of encountering icy
road surfaces increases.
(D Tips
-At temperatures below 14 °F (+ 5 °C) a
snowf lake symbol appears ahead of the
temperature display. It is intended to re­
m ind the driver to pay special attention
to
ice on the road c::> ,&. If the vehicle is
stationary, or if you are driving at a very
low speed, the temperature shown in the
display might be slightly higher than the
actual outs ide temperature. This is .,.

On-board computer
You can ca ll up the followin g in formation in
the on -board computer:
- Date
- Dr iving t ime (h) from the shor t-te rm memo-
ry
- Average consumption in MPG ( l/100 km)
from the short-te rm memory
- Average speed i n mph ( km/h) from the
short-te rm memory
- Distance driven in miles (km) from the
short-te rm memory
- Cur ren t fue l consumption in MPG ( l/100
km)
- Short-term memory overview
- Long-term memory overview
T he short-te rm memory collects driv ing infor­
mation from the time the ign ition is switc hed
on until it is switched off. If you continue driv­
ing within two ho urs after switch ing the ig ni­
tion off, the new values are included when cal­
cu lating the c urrent trip information .
Un like the short -term memory, the long-term
memory is not erased automatically. You can
select the time period for evaluating t rip in­

Fuel economy messages are displayed when
f uel consumption is increased by certa in con­
ditions. If you follow these fue l economy mes­
sages, you can reduce your vehicle's consump­
tion of fuel. The messages appear automati ­
cally and are only displayed in the efficiency
program. The fuel economy messages turn
off
automatically after a certain per iod of time .
.,. To turn an economy message
off immediate­
ly after it appears, press any button on the

The date and time are shown in the instru­
ment cluster d isplay
c:;, page 24, fig. 4. There
is also an ana log clock in the center console
c:;, fig. 12.
When you open the driver's door, the date and
time appear in the instrument cluster display
for 30 seconds . When the ign ition is switched
on, the time is always displayed in the status
line © regardless of the current display.
You can set the time on both clocks and the date display in the MMI. Refer to the MMI
owner's manual for instructions.
Service interval display
The service interval display reminds you when
your next service is due.
Fig. 13 Inst rume nt cluster: Serv ice inte rval d isp lay
The schedule for the next oil change or inspec­
tion is calculated automatically and displayed
accordingly. The display works in two stages :
Service reminder
30 days before the next service is due, a serv­
ice reminder appears in the display when you
switch the ignition on
c:;, fig. 13 .
After about S seconds the display switches back to normal. The distance and time re­
maining are updated each time the ignition is
switched on until the date due for service is
reached .
Service due
When the due date for service is reached, the
message
Service due! appears in the instru­
ment cluster immediately after you switch the
ignition on . Additionally, a warn ing tone sounds. After about 5 seconds the disp
lay
switches back to normal.
Calling up the service schedules
If or when an oil change or inspection is due,
can be shown in the MMI display by selecting
the service interval display in the car menu.
Select the
ICARI function button > Car sys­
tems
control button > Servicing & checks >
Service interval displays.
Resetting the service interval display
Your authorized Audi dealer will reset the cor­
responding service schedule after performing
the appropr iate service on your vehicle. You
also have the possibility to reset the oil
change schedule after hav ing performed an
o il change according to Aud i specif ications.
Select the
I CAR I function button > Car sys­
tems
control button > Servicing & checks >
Service Intervals > Reset oil change interval.
(D Note
If you disconnect the battery term inals, no
calculations can be made for the service
i nterval disp lay during th is time and no
serv ice reminder will appear. Remember
that observing the proper service intervals
i s vitally important to extending the life of
your vehicle, pa rticularly the engine, and
maintaining its value. Even if the mileage
driven is low, the maximum period of one
year from one service to the next must not
be exceeded.
(I} Tips
-Do not reset the display between oil
changes, otherwise the disp lay w ill be in­
correct.
- The information in the Service Reminder
remains stored
even when the vehicle
battery is disconnected .

Instrument s and warning /indicator lights
Open door/hood/rear lid warning
Fig. 14 D isplay: doors and rear lid open
With the ignition switched on, the warning il­
luminates when at least
one door or the hood
or the rear lid is not closed. The symbol also
shows you
which door(s) or lid is not closed.
In the illustration ¢
fig. 14 it is the driver's
door and the left rear door.
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 (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
ly .
If the light does not go out after the engine
is started, or illuminates while you are driv­
ing, a malfunction may ex ist 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
erat ions) and have the condition corrected.
Contact your author ized Audi dealer.
If the light illuminates, the electronic speed limiter may also be malfunctioning. For more
in formation ¢
page 30, Electronic speed
limiter.
An improperly closed fuel filler cap may a lso
cause the MIL light to illuminate¢
page 225.
On-Board Diagnostics
Fig. 15 Location of Data Link Connector (DLC)
On-Board Diagnostics monitors the compo­
nents of your emission control system. Each
monitored component in your engine system
has been assigned a code . In case of a mal­
funct ion, 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 225.
In order to make an accurate diagnosis, the
stored data can only 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
Connector (DLC). The DLC is located to the
right of the hood release
¢fig. 15.
Your authorized Audi dealer or a qualified
service station can interpret the code and per­
form the necessary repair.
A WARNING
Do not use the diagnost ic connector for
personal use. Incorrect usage can cause
malfunctions, wh ich can increase the risk
of a collision!

Electronic speed limiter
Your veh icle may be factory equ ipped with
tires that are rated for a maximum speed of
130 mph (210 km/h). This is less than the
maximum speed of your vehicle. To reduce the
risk of sudden tire failure and loss of control if
the vehicle is operated at excessive speeds,
your vehicle also has an electronic speed limit­
er. The electronic speed limiter prevents your
vehicle from going faster than the tire speed rating. For more informat ion
c::> page 259.
If the engine control unit receives faulty vehi­
cle road speed signals, the Malfunction Indi­
cator Lamp (MIU¢• will illuminate . If this
occurs, contact the nearest authorized Aud i
dealer for assistance.
58
Your vehicle's top speed is electronically limit­
ed to 155 mph (250 km/h).
If the engine control unit receives faulty vehi ­
cle roadspeed signals, the Ma lfunction Indica­
tor Lamp (MIU ¢.id will illuminate. If this oc­
curs, contact the nearest authorized Audi
dealer for assistance.
A WARNING
-
Always observe the posted speed limits
and adjust your speed to suit prevailing
road, traffic and weather conditions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires installed.
