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 so that you cannot hear or
see any steam or engine coolant .
@ 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~ turns on ¢
page 21. 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 23, 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.

Warm and cold Climate controls
Description
App lies to vehicles: with three -zone cl imate contro l or
four -zone a uto mat ic climate contro l
The climate control system warms, cools and
adds humidity to the air in the vehicle interior .
It is the most effective when the windows and
sunroof* are closed . If the temperature inside
the parked veh icle becomes very warm, open­
i ng the w indow br iefly will speed up the cool­
ing process.
In all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
drip and form a puddle of wate r under the ve­
h icle. This is normal and does not mean there
is a leak .
Pollutant filt er
The pollutant filter removes pollutants such
as dust and po llen from the air.
The air pollutants filter must be changed at
the intervals specified in your Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work .
If you drive your vehicle in an area with high
a ir pollution, the filter may need to be
changed more frequently than specified in
your Aud i Warranty
& Ma intenance booklet. If
i n doubt, ask your authori zed Audi Service Ad­
visor for adv ice.
K ey coded settings
Three-zone climate control: the blower set ­
ting and air distribution are stored automati­
cally and ass igned to the remote control key
that you are using.
Four-zone automatic climate control: The cli­
mate contro l settings are automatica lly stor­
ed and assigned to the remote control key
that is in use .

A WARNING
-
Reduced visibi lity is dangerous and can
cause acc idents .
- For safe driving it is very important that
all windows be free of ice, snow and con­
densat ion.
- Comp letely fam il iarize yourse lf with the
proper use and funct ion of the heat ing
a nd ventilation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer system in freez ing weathe r unt il you
have wa rmed the windshie ld first, using
the heating and ventilation system. The
washer sol ution may freeze on the wind­
shie ld and red uce visibi lity.
CJ) Note
- If you s uspect that the air conditioner
has been damaged, switch the system
off to avoid furt her damage and have it
inspected by a qualified dea lership .
- Repairs to the Audi air conditioner re­
quire specia l technical know ledge and
special tools. Contact an authorized Audi
dealer fo r ass istance.
@ For the sake of the envi ronment
By reducing the amount of f uel you use,
you also red uce the amount of pollutants
emitted into the air.
(D Tips
- Keep the air intake s lo ts ( in front of the
w indshield) free from ice, snow and de­
bris in order to maintain the proper func­
tion of the climate control system.
- The energy ma nagement system may
switch the seat heating* or rear window defroster off temporar ily. These systems
are available again as soon as the energy
balance has been restored .
- Air escapes through vents under the rear
window. When plac ing items of cloth ing
on the luggage compartment cover, en­
sure that the openings are not covered.
