a) Tips
The instrument illumination for the needles
and dials turns on when the ignition is turned
on and the lights are turned off. The illumina
t ion fo r the dials reduces automatically and
eventua lly turns off as brightness outside in
creases . This function reminds the driver to
turn the headlights on at the appropriate
time.
Engine coolant temperature gauge
The engine coo lant gauge (D Q page 10, fig. 3
only works when the ign ition is on. To prevent
10
damage to your engine, please note the follow
ing important points:
Engine cold
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem
perature yet. Avoid high engine speeds, heavy en
gine loads and heavy throttle applications.
Normal temperature
The engine has reached its operating tempera
ture once the LEDs up to the center of the gauge
turn on under normal driving conditions. The
LEDs higher up may turn on when the engine is
under heavy load or the exterior temperature is
high . Th is is no need to worry as long as the.
warning light in the instrument cluster does not
ill uminate .
If the LEDs in the upper area of the
display and the indicator light. in the instru
ment cluster display turn on, the coolant temper
atu re is too high
Qpage 15.
A WARNING
-Always observe the warning in <9page 216,
before opening the hood and checking the
engine coolant level.
Page 13 of 294
-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 or hear steam or coolant escap ing .
Q) Note
-Mounting additional lights or accessories in
front of the air inlets reduces the cooling ef
fect of the radiator. At h igh outside temper
atures or h igh engine load, the engine cou ld
ove rheat.
- The front spoiler has been designed to prop
erly distribute the cooling air when the veh i
cle is moving.
If the spoiler is damaged, this
could red uce the cooling effect and the en
gine could then overheat . Ask your author
ized Audi dealer for assistance.
Tachometer
The tachometer displays the engine speed in rev
olutions per minute (RPM).
You shou ld shift to the next lowest gear when
the speed is below 1500 RPM. The beginning of
the red zone in the tachometer indicates the maximum permissib le engine speed for all gears
once the engine has been broken in and when it is
warmed up to operating temperature. Before reaching the red zone, you should shift into the
next h igher gear, choose the Dor S selector lever
position, or remove your foot from the accelera
tor pedal.
CD Note
The tachometer needle© c::> page 10, fig. 3
should only be in the red zone br iefly: other
w ise, this increases the risk of e ngine dam-
age. The location where the red zo ne begins
varies depend ing on the eng ine.
@, For the sake of the environment
Upshifting early helps you to save fuel and re
duce operating noise.
In strum ents an d ind ic a to r ligh ts
Fuel level
The fue l gauge only works when the ignition is
on.
If t h e fue l level drops below 2.6 gallons (10
lite rs), the bottom LED turns red and the indica
tor light
t]J turns on c::> page 21. The bottom
LED blinks red when the fue l level is very low.
T he possible range based on the c urrent fue l lev
el is shown in tab@c::>
page 23, fig . 4 .
Fo r the tank capacity in your veh icle, refer to the
T echn ica l Data c::>
page 2 71.
CD Note
Never drive until the tank is completely emp
ty. The irregu la r supply of fuel that resu lts
from that can cause t he engine to m isfire. Un
combusted f uel w ill then en ter the exha ust
system . This can cause ove rheating and dam
age to the catalytic converter.

On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ifi in the
instrument cluster is part of the On-Board Diag
nostic (OBD II) system .
The warning/indicator light illuminates when the
ignit ion 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 wh ile you are driving, a
28
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 dea ler.
If t he light illuminates, the electronic speed lim
iter may also be ma lfunctioning. For more infor
mation ¢
page 29, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
