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 22 7, 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.
