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

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

- If the indicator light and the message ap­
pear
while dri ving , the emergency braking
function may not be available. It may not be
poss ible to set the parking brake or release
it once it has been set. Seek professional as­
s istance .
(USA models): If the warning light
1111 and
the warning light
EiJ appear together, imme­
diately contact your authorized Aud i dealer or
qualified workshop to have all brake pads in ­
spected
~ page 21 .
When the light comes on, an audib le warning
signal is also given.
.&_ WARNING
- Always observe the warnings in
~ page 22 7, before opening the hood
and checking the brake fluid .
- Driv ing with low brake fluid is a safety
hazard. Stop the car and get professional
assistance.
- If the 1111 (USA models)/ . (Canada
mode ls) brake system indicator light
tu rns on together with the ABS and ESC
indicator lights, the ABS/ ESC regu lating
function may have failed. Functions that
stabilize the vehicle are no longer availa­
ble. This could cause the vehicle to
swerve and increase the risk of sliding.
Drive carefu lly to the nearest authorized
Audi dealer or other qualif ied workshop
and have the malfunction corrected .
- If the brake warning/indicator light does
not go out after a few seconds and the
park ing brake is released, or lights up
wh ile you are driv ing, the fluid level in
the brake f luid rese rvoir is too low . If you
believe that it is safe to do so, proceed
immedi ately at low speed to the nearest
authorized Aud i dealer o r qualified repair
facility and have the brake system in­
spected.
- Always keep in mind that after several
brake applications, yo u will need g reater
pressure on the brake peda l to stop your
vehicle. Do not re ly on stra ined brakes to
respond w ith maximum stopp ing power in critical situations
. You must allow for
increased braking distances. The extra
distance used up by fading brakes could lead to an accident .
PARK/(®) Electromechanical parking brake
The warning/indicator light monitors the
electromechanical parking brake .
If the indicator light -(USA models) /.
(Canada mode ls) turns on, the parking brake
was set. If the parking brake is set when the

.. Continue driving only after the eng ine cool­
ant warn ing/ indicator light goes out .
.. Contact your authorized Audi dealer for as-
sistance if necessary .
If the engine coolant level is correct, then the
radiator fan may be the cause of the malfunc­
tion .
• Coolant temperature too high! Please let
engine run with vehicle stationary
If the indicator light turns on and the mes­
sage appears in trailer mode*, let the engine
run at idle for a few m inutes to cool down.
A WARNING
