The illum inat ion for the instrument cluster lights up whenever you
switch o n the ignition with the
vehicle headlight s off. As the daylight
fades, the instrument cluste r illum ination likewise d ims automati­
cally and w ill go out completely when the outside light is very low .
T his featu re is mean t to remind you to switch on the headligh ts when
outs ide light conditions become poor .•
Engine coolant temperature gauge
The engine coo lant gauge ~ fig . 2 © only works when the ignition is
on. To p revent damage to yo ur engine, ple ase note the following
important po ints:
Engine cold
As long as the need le remains at the le ft end of the gauge, the engine
st ill has not re ached its operating tem perature. Avoid high eng ine
speeds, heavy engine loads and heavy throttle applicat ions.
Normal temperature
When the eng ine has reached its ope rating temperature, the needle
w ill move into the midd le of the gauge and remain t he re.
If the
eng ine is working hard at high outs ide temperatures, the needle may
go furthe r to the right. This is no need to wo rry as long as the _JL
wa rning light in t he instrument cluster does not illuminate .
Warning light in the instrument cluster -t
When the _ L warning light starts to flash, this ca n mean one of two
t hings: e ither the cool ant
temperature is too h igh, or the coolant
level is too low=> page 29. _,.

If the indicator goes all the way to the right side inside the coolant
t empe ra tu re ga uge, the n th e eng ine cool ant tempe rature is too high.
Pull off the road to saf e location , turn off the engine and let it cool
down.
If the warning lig ht comes o n aga in after yo u have driven a
short distance, contact a qualified workshop.
& WARNING
• Always observe the warning in ::::> page 281 , "Engine compart­
ment ", before opening the hood and checking the engine coolant
l e vel.
• Never open the engine hood if you see or hear steam, or if you
see engine coolant dripping from the engine compartment. You
c ould burn yourself. Let the engine cool off first so that you cannot
hear or see any steam or engine coolant .
0 Note
• Mounting additiona l lights or accessories in front of the a ir in lets
reduces the cooling effect of the radiator. At high outside tempe ra ­
tu res o r high engine load, the e ng ine could ove rheat .
• T he front spoi le r has bee n designed to properly distribu te the
cooling air when the vehicle is moving . If the spoiler is damaged, this
co uld reduce the coo ling effect and the eng ine could then overheat.
Ask your author ized A udi deale r for assistance. •
Tachometer (engine rev counter)
The tac home te r indicates the engine RPM (revoluti ons
pe r minu tes) .
The tachometer @::::> page 10, fig. 2 is the left of t he two large clock­
type displays .
Th e eng ine tu rns at a speed
1,000 times t h e si ng le dig it in t he
display, e .g. if the need le is pointing at the "2" the engine is tu rning
at 2, 000 R PM.

If e ngine RPM drops below 1,500, you s hould dow nsh ift to t he next
lower ge ar. T he re d area at t he e nd of the s cale i ndic ates m aximum
permissible e ngine RPM after the break-in per iod . Before reaching
this area, move the selector lever to posit ion "D (Drive)" or ease yo ur
foot off the accelerator pedal.
0 Note
The tachome ter needle s houl d not move in to the red range. If it does,
then only fo r a very short period of time . You could damage your

& WARNING
• Always observe the warnings in ::::> page 281, "Engine compart­
ment", before opening the hood and checking the brake fluid.
• Driving with low brake fluid is a safety hazard. Stop the car and
get professional assistance.
• USA models: If the BRAKE warning light, the ~ warning light
and the warning light come on together, the rear wheels
could lock up first under hard braking. Rear wheel lock-up can
cause loss of vehicle control and an accident. Have your vehicle
repaired immediately by your authorized Audi dealer or a qualified
workshop. Drive slowly and avoid sudden, hard brake applica­
tions.
• Canada models: If the brake warning light(())), the r-warning

by pressing the [CHECK) button:
Switch off engine and check coolant level
-Pull off the road .
- Stop the vehicle.
- Turn off the engine.
- Check coolant level=>
page 297.
-Add coolant if necessary=> page 298.
-Continue driving only after the engine coolant
warning/indicator light goes out.
- Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be the
cause of the malfunction.
If the generator warning/indicator light should also illuminate
=>
page 16, then the fan belt may be damaged .
& 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=>
page 63, "Emer­
gency flasher A".
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded.
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 of

malfunction in the engine cooling system -you could damage your
engine. •
Engine oil pressure malfunction "t':::7':
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil-pres­
sure indication is likely to inflict severe damage to the
engine.
If the ~ symbol appears in the display and blinks, the oil
pressure is too low. An additional driver message can also be
displayed by pressing the [CHECK] button:

Warm and cold
Climate controls
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the following settings:
- Set the temperature to 75
°F (+23 °C).
- Press the
[AUTO] button.
With this setting, you attain maximum comfort in the least amount
of time. Change this setting , as desired , to meet your personal needs.
The climate controls are a combination of heating, ventilation and cooling systems, which automatically reduce humidity and cool the
air inside your vehicle .
The air temperature, air flow and air distribution are automatically regulated to achieve and maintain the desired passenger compart­
ment temperature as quickly as possible.
The system automatically compensates for changes in outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode ~ page 106
for year-round comfort .
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This also
prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
condensation from the evaporator may drip under the vehicle . This is
normal and does not indicate a leak.
Controls and equip ­
ment Safety first
If the outside temperature is
low, the fan normally only switches to a
higher speed once the engine coolant has warmed up sufficiently .
The air conditioner temporarily switches off when you drive off from
a standstill using full throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filter (a combined particle filter and activated char­
coal filter) reduces or prevents outside air pollution (dust, or pollen)
from entering the vehicle.
The air pollutants filter must be changed at the intervals specified in
your Warranty
& Maintenance booklet, so that the air conditioner can
properly work.
If you drive your vehicle in an area with high air pollution , the filter
may need to be changed more frequently than specified in your Audi
Warranty
& Maintenance booklet. If in doubt, ask your authorized
Audi Service Advisor for advice.
Key coded settings
The air conditioner settings selected are automatically stored and
assigned to the key being used. When the vehicle is started, the air
conditioner automatically selects the settings assigned to that key.
This way every driver will maintain his/her own personal settings and
does not have to reset them manually.
If a different driver uses your key and changes the air conditioner
settings, the latest adjustments will erase and replace the settings
you have stored.
Energy management
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts of
