The instrument illumination (for dials and
needles) turns on when the ignition is on
and the vehicle lights are turned off. As
the daylight fades, the illumination of the
dials likewise dims automatically and wil l
go out completely when the outside light
is very low. This feature is meant to rem ind
you to switch on the headlights when out­
side light conditions become poor.
Engine coolant temperature gauge
The engine coolant gauge CD¢ page 11, fig. 3
only works when the ignition is on. To prevent
damage to your eng ine, please note the fol­
l owing important points:
Engine cold
If only the LEDs at the bottom of the gauge
turn on, the eng ine has not reached operating
temperature yet . Avoid high engine speeds,
heavy engine loads and heavy throttle applica­
tions.
Normal temperature
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on under normal driving cond i­
t ions. The LEDs higher up may turn on when
the engine is under heavy load or the exterior
temperature is high. This is no need to worry
as long as the. warning light in the instru­
ment cluster does not illuminate. If the LEDs
in the upper area of the disp lay and the indica­
tor light . in the instrument cluster display
turn on, the coolant temperature is too high
¢page 17.
A WARNING
-Always observe the warn ing in
¢ page 224, before opening the hood
and checking the engine coolant level.

12 Instrum ent s and w arn ing /indic ato r light s
-Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself . Let the engine
cool off first until you can no longer see
o r hear steam or coo lant escaping.
@ Note
- Mounting additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the rad iator . At h igh outside
temperatures or high eng ine load, the
engine could overheat.
- The front spo iler has been designed to
proper ly distribute the cooling air when
t h e ve hicle is moving.
If the spoiler is
dam aged, th is co uld red uce the cooling
effect and the engine co uld then over­
heat . Ask your authorized Audi dea ler for
assistance .
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine RP M drops be low 1,500, yo u should
downshift to the next lower gear. The red a rea
at the end of the sca le indicates maximum
perm iss ib le engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position D/S (Drive) or ease
your foot off the accelerator pedal.
(D Note
The tachometer needle should on ly br iefly
be in the red zone: you could damage your
engine! The beginn ing of the red zone var­
ies depending on the engine .
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.
Fuel gauge
The fuel gauge only works when the ignition is
on .
If the fuel level d rops below 2 . 6 ga llons (10 liters), the bottom LED turns red and the
indicator light
Em turns on
¢ page 22. The
bottom LED blinks red when the fuel level is
very low.
T he possible range based on the current fuel
level is shown in tab@<=>
page 24, fig . 4 .
(D Note
Never run the tank completely dry. An ir ­
r egular supply of f uel can cause engine
misfiring and fuel could enter the ex ha ust
system . The catalytic converter could then
overheat and be damaged.
Warning/indicator Lights
Description
The ind icator lights in the instrument cluster
blink or turn on. They indicate funct ions or
malfunctions <=>,& .
Messages may appear with some indicato r
lights. A warning signal will sound at the
same t ime. The indicator lights and messages
in the center of the displays may be rep laced
by other d isplays . To show them again, select
the tab for ind icator lights and messages us­
i ng the multifunction steering wheel
Q page 24. If t here are several malfunc­
t ions, you can display them one at a time us­
ing the thumbwheel.
Some indicato rs lights in the d isplay can turn
on in severa l co lors.
A WARNING
- F ailure to heed w arning l igh ts and other
important vehicle in forma tion may res ult
in ser io us personal inj ury or vehicle dam­
age .
- Whenever stalled or stopped for repair, move the vehicle a safe d istance off the
road, stop the engine, and turn on the
emergency flasher<=>
page 44.
-The engine compartment of any motor
veh icle is a potentially hazardous area.

EPC Electronic powe r control
App lies to vehicles: with gaso line engine
This warning/indicator light monitors the
electronic power control .
The Ga warning/ indicator light (Electron ic
Power Control) illuminates when you switch
the ignition on as a function check .
@ Tips
If this warning/indicator light illuminates
while you are dr iving, then there is a mal­
function in the engine electron ics. Have
the malfu nction corrected as soon as pos-
l ) - : USA models only
-
'
sible by your authorized Audi dealer or
qualified repair facility .
W Glow plug system
Applies to vehicles: with diesel eng ine
The control light illuminates when the glow
plug system is active.
If the II i ndicato r light illum inates, the g low
pl ug system is a ct ive. You sho uld start the en­
gine immediately after the ind icator light
switches off. The indicator light only illum i­
nates for approximate ly 1 second if the en­
gine is warm or if the outs ide temperature is
above 46 QF (8 Q().
(l) Tips
-If the glow plug indicator light illum i­
nates while dr iving, there is an eng ine
control malfunction. The engine should
be checked immed iate ly.
- If the ind icator light does not illuminate
at all when switch ing the ign it ion on,
there may be a malfunction in the glow
plug system. The engine sho uld be
ch ecked.
0 Malfunction Indicator Lamp (MIL)
T he Ma lf u nction Indicator Lamp ( MIL) is pa rt
of the On-Board Diagnostic (OBD II) system.
T he symbo l
¢.j lights up when the ignition is
switched on and will turn off after the engine
has started and has settled at a constant idle
speed. This indicates that the MIL is work ing
properly.
The warning lig ht ill uminates when there is a
malfunction in the engine electron ic system.
Contact your a uthorized Audi dea ler and have
the malfunction corrected.
An improperly closed fuel filler cap may a lso
ca use the MIL light to illuminate

@ Tips
- Sunglasses with polarization fi lters and

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 o ut 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 while you are driv­
ing, a ma lfunction 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
r=.> page 31,
Electronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c:>page 218.
On-Board Diagnostics
Fig. 16 Locat ion of Data L ink Con nector (DLC)
On-Board D iagnost ics monitors the compo­
nents of your em iss ion control 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.
T he MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem.
If the light illum inates after a refuelling,
stop the vehicle and make sure the fuel filler
cap is properly closed
c:> page 218.
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
r=.> fig . 16 .
Your authorized Audi dea ler or a qualified
serv ice station can interpret the code and per­
form the necessary repair.
A WARNING
Do not use the diagnostic connector for
personal use. Incorrect usage can cause
