Normal temperature
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on under norma l driving conditions . 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.
warn ing light in the instrument cluster does not
illuminate . If the LEDs in the upper area of the
d isplay and the ind icator light . in the instru­
ment cluster display tu rn on , the coolant temper­
ature is too high
¢page 15.
_& WARNING
-Always observe the warning in ¢ page 220,
Working in the engine compartment,
before
opening the hood and checking the engine
coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment. You
could burn yourself. Let the engine cool off
first so that you cannot hear or see any
steam or engine coolant.
(D 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 high engine load, the engine could
overheat .
- The front spoiler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving.
If the spo iler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­
iz ed Audi dealer for assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revo­
lutions per minutes).
If engine RPM drops below 1,500, you should
downshift to the next lower gear. The red area at
the end of the scale indicates maximum permis­
sib le eng ine RPM after the break-in period. Be­
fore reaching this area, move the selector lever
Instruments and indicator lights
to position "D (Drive)" or ease your foot off the
acce lerator pedal.
(D Note
The tachome ter needle should only briefly be
in the red zone: you could damage your en­
gine! The beginning of the red zone varies de­
pending on the engine .
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.
Fuel gauge
The fue l gauge only works when the ignition is
on. If the fuel level drops below 4 gallons (15 lit­
ers), the bottom LED turns red and the indicator
l ight tllturns on
¢page 21. The bottom LED
blinks red when the fue l level is very low .
The possible range based on the current fue l lev­
el is shown in tab@¢
page 23, fig. 4.
(D Note
Never run the tank completely dry. An irregu­
l ar supply of fuel can cause engine misfiring
and fuel could enter the exhaust system. The
catalytic converter could then overheat and
be damaged.
Indicator Lights
Description
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or mal­
funct ions¢ ,&..
Messages may appear with some indicator lights.
A warning signal will sound at the same time.
The ind icator lights and messages in the center
of the displays may be replaced by other displays.
To show them again, select the tab for indicator lights and messages using the multifunction
steering wheel¢

brake system inspected.
- Always keep in mind that after several brake
applications, you will need greater pressure
on the brake pedal to stop your vehicle. Do
not rely on strained brakes to respond with
maximum stopping power in critical situa­
tions. You must allow for increased braking
distances . The extra distance used up by
fading brakes could lead to an accident.

Warm and cold
Climate control system
Description
The climate control system warms, cools and
adds humidity to the air in the veh icle inter ior. It
is the most effective when the windows and sun ­
roof* are closed . If the temperature inside the
parked vehicle becomes very warm, opening the
window briefly will speed up the cooling process.
I n all heating mode functions except
defrost, the
b lower only switches to a higher speed once the
engine coolant has reached a certain tempera­
ture .
Condensat ion from the cooling system can drip
and form a puddle of water under the veh icle.
This is normal and does not mean there is a leak.
P ollutant filt er
The po llutant filte r removes pollutants such as
dust and pollen from the a ir.
The air pollutants filter must be changed at the intervals specif ied in your Warranty
& Mainte­
nance booklet, so that the a ir cond it ione r can
properly work.
If you drive your vehicle in an area with high air pollut ion, the filter may need to be changed
more frequently than specified i n your Aud i Wa r­
ranty
& Maintenance booklet. If in doubt, ask
your author ized Audi Service Advisor for advice.
Key cod ed setting s
The climate control settings are automatically
stored and assigned to the remote contro l key
that is in use .
.8, WARNING
Reduced visib ility is dangerous and can ca use
accidents.
- For safe dr iv ing it is very impo rtan t that a ll
windows be free of ice, snow and condensa­
t ion .
76
- Complete ly familiarize yourself with the
proper use and function of the heating and
ventilation system and espec ially how to de­
fog and defrost the wi ndows .
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshield first, using the heat­ ing and vent ilation system. The washer solu­
tion may freeze on the windshield and re­
duce visibi lity.
(D Note
- If you suspect that the air conditioner has
been damaged, sw itch the system off to
avoid further damage and have it inspected
by a q ualified dealership.
- Repa irs to the Aud i air cond itioner requ ire
special techn ica l know ledge and spec ial
tools. Contact an a uthorized Audi dealer fo r
assistance.
@ For the sake of the environment
By reduc ing the amo unt of fuel you use, you
also red uce the amount of pollutants emitted
into the a ir.
(D Tips
- Keep t he a ir intake slots (in front of the
windshield) free from ice, snow and debr is
in orde r to maintain the prope r funct ion of
the climate control system .
- The energy management sys tem may sw itch
the seat heating* o r rea r window defroster
off temporarily. These systems are available
again as soon as the energy balance has
been restored.
- Air escapes through vents under the rear
window. When placing items of clothing on
the luggage compartment cover, ensure
that the openings are not covered.
