- 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

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 lig ht 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 16 .

~ Contact your authorized Audi dea ler for as -
sistance if necessary.
If the engine coolant level is co rrect, then the
radiator fan may be the cause of the malfunc­
tion.
If the generator wa rning/ind icator light
should also illuminate
r:!:> page 16, then the
fan belt may be damaged.
A WARNING
- If your vehicle should break down for
mechanical or other reasons, park at a
safe distance from moving traffic, turn
off the engine and turn on the hazard
warning lights

illum inates. There is a ma lf u nct ion in the
eng ine cooling system -you co ul d damage
your eng ine.
@ Electro-mechanical power assist
If the indicator lig ht illuminates w hile you are
driving, there is a malfunction in the electro­
mechanical steering. If the ind icator light is
show ing ,£"~ . there may be a reduction in pow­
er steering assist. If the ind icator light is
show ing . , there may be a total loss of pow­
e r steering assist. The stee ring m ust be in­
spected immediately by a qua lified wor kshop

engine. For safety reasons, the eng ine will on ­
ly start when the clutch peda l is pressed.
;;,I C; Electronic Stabilization Control
(ESC)
If the hJ indicator lamp blinks while dr iv ing,
the ESC or ASR (Anti-Slip Regu lation) is active ­
ly regulating .
If the
G! indicator lamp illuminates, the sys­
tem has switched the ESC off. In th is case, you
can switch the ignition off and then on to
switch the ESC on again. The system is func­
t ion ing complete ly when the ind icator lamp
swi tches off.
If the
I) indicator lamp illuminates, the ESC
was switched off w ith the
[ru button .
Stabilization program and AB S fault! See
owner 's manual
If the G! indicator lamp and the [I] ABS indi­
cator lamp illum inate and the driver message
appears, the ABS or electron ic different ia l lock
is malfunct io ning . This also interrupts the
ESC. The brakes still function with their nor ­
mal power, but ABS is not active.
Drive to your authori zed A udi dealer immedi­
ate ly to have the malfunction corrected .

Warm and cold
Climate controls
Controls
The air conditioning automatically maintains the selected temperature in the vehicle interior
throughout each season .
Fig. 68 Climate contro ls
We recommend the following sett ing :
> Rotate the knob ¢ fig. 68 @to the right to
switch on the air conditioning .
> Set the temperature to 72 °F (22 °() .
> Press the !AUTO I ¢ fig . 68 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 persona l comfort
l eve ls or ce rtain circumstances requi re it .
The climate controls are a combination of au ­
tomatic heating and ventilation systems and a
coo ling system which dehumidifies and coo ls
the air ins ide the veh icle.
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 ai r d ist ribution are also auto­
mat ical ly adjusted . The system also takes into
account strong s unshine so that manua l ad­
justment is not necessary. So in almost all cases,
a ut om at ic mode offers the best cond i­
tions for the comfort of the occupants at all
times of the year ¢
page 69.
Please not e:
In cooling mode , relative humidity in the inte­
rior is reduced . This prevents the w indows
from fogg ing up.
When relative hum idity and temperatures
outside are high ,
conden sati on 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 outs ide 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 ing.
When accelerating at wide-open throttle, the air conditioning compressor is temporarily
switched off to ma intain 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.
Funct ions are set by turning the rotary knob
or switched on and off by tapp ing the buttons.

CD Note
-Avoid high engine speeds, fast accelera­
tion or heavy engine loads whi le the en­
gine is still cold. This could damage the
engine.
- The engine cannot be started by pushing or towing the veh icle.
@) For the sake of the environment
To avoid unnecessary engine wear and to
reduce exhaust emissions, do not let your
veh icle stand and warm up. Be ready to
drive off immediately after starting your
veh icle. Maintain moderate speed until the
eng ine is completely warm . Remember,
the engine performs best at operating
temperature .
Stopping the engine
~ Turn the ign ition key to position @
~page 71, fig. 71.
_& 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 engine 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.
CD Note
Do not stop the engine immed iate ly after
hard or extended driving. Keep the engine
running for approximately two minutes to
prevent excessive heat build-up.
