A WARNING
- Always observe the warning in
c::> page 195 , 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
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 .
(D Note
-Mounting additional lights or accessories
in front of the air inlets reduces the cool­
ing effect of the rad iator. At high outside
temperatures or high eng ine load , the
engine could overheat.
- The front spoiler has been designed to
properly distribute the cooling air when
the veh icle is moving .
If the spoiler is
damaged , this cou ld reduce the cooling
effect and the engine co uld then over­
heat. Ask your authorized Aud i dealer for
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
I f engine RPM drops below 1,500, you should
downshift to the next lower gear . T he red area
at the end of the scale indicates maximum
perm issible engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position 0/5 or ease your foot
off the accelerator pedal.
@) Note
The tachometer needle@c::> page 10 ,
fig. 3 shou ld only briefly be in the red
zone: you could damage your engine! The
beg inning of the red zone varies depend-
ing on the engine .
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

Warm and cold Climate controls
Description
Th e climate control sy stem warms, cools and
adds humidity to the a ir in the veh icle inter io r.
It is the most effect ive when the windows and
power top are closed. If there is a build-up of
h eat inside the vehicle, ventilation can help to
speed up the cooling process .
I n all he ating mode f unctions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temp erature.
Condensat ion from the cooling sys tem can
d rip and form a puddle of water under the ve­
h icle. This is normal and does not mean there
is a leak .
Pollutant filter
The po llutant filte r removes po llutants s uch
as dus t and pollen from the air.
The air pollutants filte r must be changed at
the intervals spec ified in you r Wa rra nty
&
M aintenance book let, so tha t the air condi­
tioner can prope rly work .
If you drive your vehicle in an area w ith h igh
a ir po llution , the fi lter may need to be
changed more frequent ly than specified in
your Aud i Warranty
& Ma intenance bookle t. If
in doubt, ask your authorized A udi Service Ad ­
v isor for advice .
Key coded settings
The clima te control sett ings are automat ically
stored and assigned to the remote co ntro l key
that is in use. These set tings are differe nt
when the power top is open or closed .
& WARNING
Reduced visibility is dangero us and can
cause accidents . -
Warm and cold 69
-For safe driving it is very important that
all windows be free of ice, snow and con­
densat ion.
- Comp letely fam iliarize yourse lf with the
proper use and funct ion of the heat ing
and ve nti lation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer
system in freez ing weather unt il you
have warmed the w indshield first, using
the heating and ventilation system. The
washer sol ution may free ze o n the wind­
shie ld an d red uce visib ility.
(D Note
- If you s uspect that the air conditioner
has been damaged, switch the system
off to avoid furt her damage and have it
i n spected by a q ua lified dea lership.
- Repairs to the Audi air condition er re­
quire specia l techni cal know ledge and
speci al tools. Contact an autho rized Aud i
dealer fo r ass istance.
@ For the sake of the environment
B y reduci ng the amou nt of f uel you use,
you also re duce the amount of pollu tan ts
emitted in to the a ir .
(D Tips
- Keep the air intake s lo ts ( in fro nt of the
w indshield) free from ice, snow and de­
br is in order to maintai n the proper f unc ­
tion of the climate control system.
- T he energy m anagement 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 placing items of clothing
on the luggage compartment cover, en­
sure that the openings are not covered.
