- When switching the ignition on, the nee­
dles in the instrument cluster move up­
ward briefly.
- The illumination for the instrument clus ­
ter lights up whenever you switch on the
i gnition with the
vehicle headlights off .
As the daylight fades, the instrument
cluster illumination likewise dims auto­
matically a nd will go out completely
when the outside light is very low. This
feature is meant to remind you to switch
on the head lights when outside light
conditions become poor .
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions 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
permissible engine RPM after the br eak-in pe­
riod. Before reaching this area, move these­
lector lever to position "D (Drive)" or ease
your foot off the acce lerator pedal.
(D Note
The tachometer needle should only briefly
be in the red zone: you could damage your
engine! The beg inning of the red zone var­
i es depending on the engine.
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

Engine coolant temperature gauge
The engine coo la nt gauge ¢ page 10 , fig. 3@
only works when the ign ition is on. To prevent
damage to your e ngine, please note the fo l­
l owing important points:
Engine cold
As long as the nee dle rem ains a t the left end
of the gauge, the engine s till h as not reac hed
its operating temperat ure. Avoid high engine
speeds, heavy engine loads and heavy throt­
tle.
Normal temperature
W hen the engine has re ache d its ope rat ing
temperature, the need le w ill move into the
mid dle of t he gauge and rema in there .
If the
engine is working hard at high outside tem ­
peratures, the needle may turn fu rther to the
right. This is no cause for concern as long as
the . warni ng light in the inst rument cl uster
does not illuminate .
When the. war ning light starts to flash,
th is can mean one of two thi ngs: either the
coolant
temperature is too high, o r the coo l­
ant
level is too low ¢ page 17 .

_L Engine cooling system
A malfunction in the engine cooling system
must be repaired as soon as possible .
When the. symbol in the display flashes,
then either the eng ine coolant
temperature is
too h igh, or the coolant
level is too low . In ad­
d ition to the symbol, the fo llowing message
a lso appears in the display:
Sw it c h off engin e and ch eck coo lant l evel
~ Pull off the road and stop the vehicle.
~ Turnoff the engine.
~ Check coolant level ¢ page 173.
~ Add coolant if necessary ¢ page 173 .
~ Conti nue driving only after the eng ine cool­
ant warn ing/ indicator light goes out .
~ Contact you r authorized Audi dea le r fo r as-
s istance if necessary .
If the engine coolant level is correct, then the
radiato r fan may be the cause of the malfunc­
tion .
If the generator warning/ind icator light
should also illuminate ¢
page 16, then the
fan belt may be damaged .
A WARNING
-If your veh icle should break down for
mechanical or other reasons, park at a
sa fe distance from moving traffic, turn
off the engine and turn on the hazard
warning lights ¢
page 51, Emergency
flasher.
- Never open the hood if you see or hear
steam or coolant escaping from the en­
gine compartment - you risk being scald­
ed . Wait until you can no longer see or
hear steam or coolant escaping . -
The engine compartment of any vehicle
is a dangerous area . Before you perform
any work in the engine compartment,
turn off the eng ine and allow it to cool.
Follow the warn ing stickers .
(D Note
Do not continue dr iv ing if the . symbol
ill uminates. There is a malfunction in the
engine cooling system -you could damage
your engine .
~ Electro-mechanical power assist
If the indicato r light illum inates while you are
driv ing , there is a malfunction in the electro­
mecha nica l steering. If the indi cator light is
showing
'".[-1. there may be a reduction in pow ­
er steering assist. If the indicator light is
showing ., ther e may be a tota l loss of pow ­
er steering assist. The stee ring must be in­
spected immed iately by a qualified workshop
¢ .&. .With the eng ine not running (e.g . when
the car is being towed), there is also no power
ass ist available .
A WARNING
-
If there is a ma lfunction, the indicato r
l ight for the electro-mechanical power as­
sist il l uminates. Seek pro fessional assis­
tance.
~ Convertible top
The warning/indicator light monitors the con­
vertible top function .
The !I warning/ indicator light illumi nates
when you switch on the ignition for about 2 seconds as a check and then goes out. The
warning/indicator ligh t has the following
functions :
- The light illumi nates when the foldi ng top
opens or closes.
- I t flashes if one of the cond it ions for auto­
mat ically lower ing or ra is ing the convertible
top is no t met and the switch to actuate the

Climate controls
Controls
The air conditioning automatically maintains the selected temperature in the vehicle interior
throughout each season .
Fig. 79 Climate contro ls
We recommend the following sett ing :
> Rotate the knob 9 fig. 79 @ to the right to
switch on the air conditioning .
> Set the temperature to 72 °F (22 °().
> Press the !AUTO !~ fig. 79 button .
Using the previously recommended setting is
the quickest way to achieve a comfortable cli ­
mate in the vehicle . This setting should there­
fore only be changed when personal comfort
l eve ls or certain circumstances require it.
The climate controls are a combination of au ­
tomatic heating and ventilation systems and a
coo ling system which dehum idifies and coo ls
the air inside the vehicle.
The climate controls automatically maintain a temperature once it has been set. The tem­
perat ure of the air from the vents, fan speed
(air vol ume) and air distribution are also auto­
matically adjusted . The system also takes into
account strong sunshine so that manua l ad­
justment is not necessary. So in almost all
cases,
automatic mode offers the best condi­
tions for the comfort of the occupants at all
times of the year
9 page 71 .
Please note :
In cooling mode , relative humidity in the inte­
rior is reduced . This prevents the windows
from fogg ing up.
When relative humidity and temperatures outside are high ,
condensation can drip from
the a ir condition ing evaporator and form a
pool of water under the vehicle. This is normal
and not an ind ication of a leak!
When outside temperatures are low, the fan
does not switch to a higher speed until the
coolant has reached an adequate tempera ­
tu re, with the exception of the defrost set­
t in g.
When accelerating at wide-open throttle, the air conditioning compressor is temporarily
switched off to maintain full engine power.
In order to ensure engine cooling under ex­
treme engine loads, the compressor is switch­
ed off if coolant temperatures climb too high.
Functions are set by turning the rotary knob
or switched on and off by tapp ing the buttons.

@ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions, do not let your
vehicle stand and warm up. Be ready to
drive off immediately after start ing your
veh icle. Mainta in moderate speed until the
engine is completely warm . Remember,
the engine performs best at operating
temperature .
Stopping the engine
.,. Turn the ignition key to position @
¢page 73, fig. 82.
_& WARNING
-Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the
power steering is not guaranteed. You
must use more force to turn or brake if
necessary . Because you cannot steer and
brake as you usually would, this could
lead to crashes and serious injur ies.
- The radiator fan can continue to run for
up to 10 minutes even after you have
turned off the eng ine and removed the
ignition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build-up in the engine compartment .
(D Note
Do not stop the engine immediately after
hard or extended driving. Keep the engine
r un ning for approximately two minutes to
prevent excessive heat build-up.
